2 Welcome to the Summer School This year s workshop on "Interfacial phenomena in theory and practice" is a continuation of the tradition of Summer Workshops originating from the postgraduate students meetings organized by SURUZ - Scientific Network Surfactants and Dispersed Systems in Theory and Practice since Improvement of quality of life, protection of the environment and economical use of energy and raw materials are requirements of our times. Miniaturization, which is one of the answers to these needs, means moving from macro- to micro- and nano-dimensions and to finely dispersed systems. The aim of SURUZ was to network high quality scientific centers in Poland, which were involved in research on surfactants and dispersed systems. The activities of the network concentrated on the basic research as well as on development of new compounds and technologies, which find practical application. The organization of the network facilitated exchange of the personnel, information and dissemination of scientific results. It contributed to optimization of use of research infrastructure available to the members of the network. The exchange of PhD students and young scientists was especially encouraged to enable learning the techniques, which are not available in their home institutions. Organization of the network was supposed to prevent fragmentation, overlap of the research topics and favor cooperation. Although the project was finished in 2007 the annual meetings as summer school at the Sudomie Lake have been continued. This year s workshop will be attributed to the latest achievements and developments in surfactants, nanoparticles, photocatalysis, biochemistry and as a new topic at the school- the processes involved in the shale gas exploration. As an interdisciplinary meeting it aims at bringing together researchers working on elucidation and better understanding of surface phenomena on process engineering. A broad scientific program includes lectures given by professors, oral presentations given by young scientists and numerous discussions. We are also proud to host once more during this year's session a great physicochemist, honorary Chairman of J. Haber Institute of Catalysis and Surface Chemistry of Polish Academy of Sciences in Cracow Professor Andrzej Pomianowski. During Workshop, our Special Guest will introduce speech about Advances in knowledge on the colloids of nano-metric dispersion presenting recent research advances on the subject of layered silicates, which due to their crystal structure may to turn to the liquid crystalline state due to hydration process. Such transition enabled rapid development in the new field of basic research. Layered silicates are used in such diverse fields exploitation of shale gas or production of nano-tech composite materials. We welcome back those of you who have pioneered with us in the past, as well as those who will be joining us for the first time. We are convinced that you will find the time spent in Sudomie inspiring pleasant and productive. Jan Hupka 2 BA-2

17 DETERMINATION OF ASPHALT-AGGREGATE ADHESION Robert Aranowski 1, Przemysław Wojewódka 1, Krzysztof Błażejowski 2 1 Gdansk University of Technology, Chemistry Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk, Poland 2 ORLEN Asfalt Sp. z o.o. ul. Chemików 7, Plock, Poland One of the main factors of asphalt pavements resistance for asphalt stripping is the adhesion between asphalt binder and the mineral aggregate. There are currently no standard laboratory test procedures that can quickly and accurately measure the strength of the interaction (bond) between the binder and aggregate. One of the most simple methods to evaluate the adhesion forces is the contact angle measurement. Contact angles at the mineralbinder-air interface were measured using a high temperature contact angle goniometer by a sessile drop technique. The influence of five different adhesion promoters that varied in chemical composition and two mineral aggregates (limestone and granite) has been analyzed in wide range of temperature (40 C 200 C). The road binder 35/50 (pen@25 C F) was used as the bituminous phase. Four adhesion promoters used in research affect the contact angle decrease at granite aggregate in higher temperature range (above 75 C), comparing to pure binder. In case of limestone, the difference of measured contact angles between pure binder and binder with additives is not evident and one can say that activity of some promoters is neutral or adhesion could be even worse. Full range temperature contact angle measurements can be used in estimation of asphalt aggregate adhesion in warm mix asphalt technologies. 17

18 TRANSPORT PROPERTIES OF LAYER-BY-LAYER ASSEMBLIES OF SPHERICAL PARTICLES AT SOLID/LIQUID INTERFACE Piotr Batys, Paweł Weroński Jerzy Haber Institute of Catalysis and Surface Chemistry PAS, Kraków, Poland Recent advances in the nanotechnology have made possible the production of functional colloidal materials with controlled surface and bulk properties, such as surface-activated, magnetic, conductive, biocompatible, fluorescent, hollow, or nanoporous particles. The ability of colloidal particles to self-organize opens up a big world for novel applications of their multilayer structures. In this work we present computer simulation results of the layer by layer self-assembling process of colloidal particles. We have generated five multilayer structures of monodisperse spherical particles according to a generalized model of random sequential adsorption of hard spheres [1]. We have studied five multilayers of similar thickness, each created at a different single-layer surface coverage = a 2 /N, where a and N denote the particle radius and number density, respectively. Our results suggest that the single-layer coverage has a significant effect on the film transport properties [2]. The local values of multilayer porosity and tortuosity exhibit decaying oscillatory variations in the distance range dependent on the surface coverage (see Fig. 1). Fig. 1. Porosity as a function of distance from adsorption surface, calculated for single-layer coverage Dashed line denotes mean porosity. Graph to the right represents corresponding multilayer slice of thickness 5a. The mean multilayer porosity and tortuosity describe equations linear with respect to the surface coverage. The mean tortuosity and porosity of multilayer created with our model are also connected by a linear equation valid for any single-layer coverage and number of layers (see Fig. 2). FIG. 2. Mean tortuosity as a function of mean porosity of 1, 2, 5, and 10-layers. Symbols denote, from right to left, values corresponding to coverage 0.10, 0.20, 0.30, 0.40, and Line represents theoretical predictions. Our results suggest that all the film characteristics strongly depend on the method of its preparation and can be controlled by manipulating the single-layer surface coverage or deposition time. The results can be useful for efficient designing multilayers with desired properties. 1. P. Batys and P.

19 ESTIMATION OF ORGANIC FRACTION OF MUNICIPAL SOLID WASTE AND ITS ELUATE IN METHANE FERMENTION PROCESS Nikola Chruściel Gdańsk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdańsk, Poland Advisor: Jan Hupka Climbing he waste hierarchy, anaerobic digestion is an attractive method of waste treatment especially for the organic fraction of municipal solid waste (ofmsw). OFMSW and garden waste, depending on the season with putting the European Council Directive on the Landfill of Waste 1999/31/EC into nation legislation, Poland is faced to treat the high organic fraction in its MSW. This paper assesses the possibility of OFMSW fermentation and its eluate (water solution of washed wastes) and to convert organic substrates into biogas. MSW are composed of food, green and garden waste, which make the wastes heterogeneous in composition and structure [1-2]. Two organic fractions of MSW were considered as a substrate: source separated OFMSW and mechanically separated OFMSW. 1. Luning L., E.H.M. van Zundert, A.J.F.

20 A NOVEL GROUP OF INORGANIC MATERIALS OBTAINED VIA SOL-GEL ROUTE DEDICATED FOR ENVIRONMENTAL APPLICATIONS Filip Ciesielczyk, Milena Przybysz, Przemysław Bartczak, Teofil Jesionowski Institute of Chemical Technology and Engineering, Faculty of Chemical Technology, Poznan University of Technology, M. Skłodowskiej-Curie 2, Poznan; Poland; Recent years have seen a noticeable rapid development of technologies and methods for the synthesis of inorganic powders, which are used in various industries (such as the ceramics, pharmaceuticals, food, cosmetics and construction industries). Among the many common techniques, one that is quite widely used is the sol-gel method [1]. The sol-gel method can be used for the synthesis of a large number of compounds, including hybrid powders, nanocomposites, nanopowders, and many others [2]. Due to the flexibility of its process parameters, it can be used in many areas of science and industry, including medicine and dentistry. The sol-gel method ensures the high purity of the products and the possibility of mixing organic and inorganic components on a nanometric scale. The process usually takes place at low temperature and in mild reaction conditions, which permits, for example, the trapping of molecules such as enzymes or proteins, which have low thermal and chemical stability [3]. The efficiency of the sol-gel process is affected by several parameters, including temperature, ph, amount and type of solvent used, type of catalyst and metal precursor, as well as the concentration of reagents. Very often the sol-gel method is used for the preparation of hybrid materials. The powders thus obtained, subjected to a calcination process, in many cases exhibit interesting crystalline structures with a broad spectrum of application [4]. With regard to the dynamic development of industry and the continuing need for new multifunctional materials, an attempt was made to produce a novel xmgo ysio 2 powder with defined physicochemical properties, including specified crystalline and porous structure. The powders were prepared by the sol-gel process using magnesium ethoxide as the organic precursor of magnesium, methyl alcohol as the solvent, the base catalyst 25% ammonia, and the silicon precursor tetraethoxysilane (TEOS). The investigated properties of the powder confirmed its high level of activity and ability to adsorb selected hazardous metals ions from aqueous solutions, and the efficiency of adsorption was strongly dependent on the contact time of the reactants, the type of metal ion precursor used, and especially on the ph of the reaction medium. 1.

The effect of calcination temperature (from 350 to 700 C) and source TiO 2 on the structure and properties of TiO 2 loaded with Au/Pd nanoparticles will be presented (Table 1). In addition, size and shape of nanoparticles using electron microscopy (TEM and SEM), surface area (BET), phase composition (XRD), the surface compsition (XPS) and study mechanism of radical O - under visible light by in-situ technique EPR will be showed.

22 MASS TRANSPORT IN PERVAPORATION Anna Dawiec, Anna Witek-Krowiak, Zygmunt Sadowski Wroclaw University of Technology, Faculty of Chemistry, Institute of Chemical Engineering, Norwida 4/6, Wroclaw, Poland Pervaporation is a membrane separation process, where selected compounds from the multicomponent solution are selectively transported through the dense, composite membrane. One of the biggest challenge in the designing of the pervaporation process is selection of the appropriate membrane material, because interactions between the penetrant and the polymer membrane material, as well as its mobility through the membrane matrix, determines the selectivity and efficiency of the process. Nowadays, most of the research is related to the development of new membrane materials, however fundamental is understanding of the mass transfer through the dense membrane. Some models were proposed to predict the mass transport of the penetrants through the PV membranes, including the solution-diffusion model[1], the pore flow model[2], the resistance-in-series model[3], and the molecular dynamic simulation[4]. Generally, the solution-diffusion theory is the most commonly used to describe the mass transport in PV process. According to this theory, the mechanism of the transport process can be divided into three steps: a) the selective sorption of molecules at the upstream side of the membrane, b) the diffusion through the membrane material, c) the desorption and evaporation at the permeate side of the membrane. This paper discusses the mass transfer theoretical fundamentals in the pervaporation of aroma compounds through hydrophobic membrane. The sorption and diffusion steps will be described in detail including the most wildly used mathematical models. On the basis of theoretical consideration, the mass transport mechanism can be successfully predicted leading to optimization and scaling up of the process. 1. Wijmans, J.G., R.W.

23 COPPER BIOMIMETIC COMPLEXES AS POTENTIAL COMPONENTS OF FUEL CELLS Sylwia Godlewska, Katarzyna Baranowska, Anna Dołęga Gdansk University of Technology, Chemical Faculty, Department of Inorganic Chemistry, Narutowicza 11/12, Gdansk, Poland Faced with depletion of fossil fuels our civilization have to find alternative ways of producing energy. Therefore fuel cells are currently the subject of interest to many researchers. Compared to conventional energy production the fuel cell does not generate pollution which is an important advantage to environment. Therefore they could be promising energy source. Laccases are copper proteins that belong to the family of blue multicopper oxidases. Their active site consists of copper - imidazole cluster and catalyzes the four-electron reduction of dioxygen to water.[1] The ability of laccases to reduce dioxygen has inspired several research groups to study laccases as cathode catalysts in the fuel cell.[1-3] Inspired by the information founded in literature we considered possibility of using of copper complexes as part of fuel cell cathode. Till now we have synthesized a series of copper complexes with N- and O- ligand. All obtained compounds will be described in the presentation. 1. M. Smolander, H. Boer, M. Valkiainen, R. Roozeman, M.

24 PHOTOCATALYTIC ACTIVITY OF TiO 2 LOADED WITH MONOMETALLIC AND BIMETALLIC Au AND Pt NANOPARTICLES Anna Gołąbiewska 1, Anna Zielińska-Jurek 1, Wojciech Lisowski 2, Marcin Jarek 3, Grzegorz Nowaczyk 3, Adriana Zaleska 1 1 Gdansk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk,Poland 2 Mazovia Center for Surface Analysis, Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland 3 NanoBioMedical Center, Adam Mickiewicz University, Umultowska 85, Poznan, Poland In the present work, we received TiO 2 nanocomposites modified by monometallic (Au,Pt) and bimetallic (Au/Pt) nanoparticles. The aim of this study was to determine the effect of deposition of metal nanoparticles and matrix type on photocatalytic activity in visible light of Au/Pt-TiO 2 and Pt-TiO 2 photocatalysts prepared using a water-in-oil microemulsion system of water/aot/cyclohexane. The obtained photocatalysts were subsequently characterized by a BET surface area method and X-ray powder diffraction analysis (XRD), transmission scanning electron microscope (STEM), diffuse reflectance UV Vis spectra (DRS) and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity of noble metal modified-tio 2 powders under visible light irradiation was estimated by measuring the decomposition rate of phenol in an aqueous solution. The results indicated that phenol degradation rate under visible light in the presence of TiO 2 loaded with Au/Pt nanoparticles differed from 0.7 to 2.2 µmol dm min for samples prepared using different reducing agent as show in Table 1. Sodium borohydride (NaBH 4 ) favors formation of smaller Au/Pt nanoparticles and higher amount gold in Au/Pt is in the form of electronegative species (Au δ- ) resulted in higher photoactivity. TiO 2 obtained by TIP hydrolysis in microemulsion system seems to be the best support for Au/Pt nanoparticles from all among investigated matrix.

25 MULTISCALE CHARACTERIZATION OF TRANSPORT PHENOMENA IN GEOMATERIALS Jan Góral The University of Utah, College of Mines and Earth Sciences, Department of Mining Engineering, UT Recently discovered massive unconventional oil and gas resources have become an increasingly important factor in the global energy outlook. Because the demand for energy is expected to increase significantly in the near future, oil and gas is expected to play an increasing role in the future power mix and global energy outlook. Despite the discovery of large number of proven unconventional oil and gas reserves across the world, petroleum industry is facing numerous technical challenges that are limiting feasibility of oil and gas production. One of the most important challenges facing the development of unconventional oil and gas technologies is an inadequate understanding of the transport phenomena within porous geomaterials matrix. A detailed description of transport phenomena is crucial for accurate predictions of multicomponent fluid transport and, ultimately, for optimizing oil and gas exploration and production. Understanding geophysical, geochemical and geomechanical properties of the reservoirs is essential from both the scientific and economic perspective. Any and all of potential solutions for optimal shale gas extraction relate to characterizing mechanisms of transport phenomena and formation damage, which are generally associated with diffusive or mechanical interactions between treating fluid, formation fluid, and the formation rock itself. Successful representation and quantification of stimulation triggered hydraulic, geochemical, and geomechanical processes within wellbore, reservoir, and caprock environments requires modeling and simulation approach that explicitly integrate these processes. Precise information about geophysico-chemical and geomechanical properties along with transport characteristics will help enhance predictive capability of well and reservoir performances, provide a new basis for reservoir stimulation design, and improve water management. The proposed research approach will provide a better understanding about changes in 4D reservoir fluid distributions across the full reservoir lifecycle and significantly reduce the uncertainty about direction and extent of fracturing fluid propagation. 25

26 ROLE OF ENDOTHELIUM IN TARGETED DRUG DELIVERY Janina Grodzka, Andrzej Pomianowski Jerzy Haber Institiute of Catalysis and Surface Chemistry, Polish Academy of Science, Niezapominajek 8, Cracow, Poland The endothelium is the net of the practically one-molecular thickness cells (endothelial reticulum) that are surrounding every organ, playing various functions. The first of the basic endothelium functions is the control of possibilities and rates of the substances exchange between cells within the endothelium and the remaining parts of the organism. This exchange may be "passive" (dependent on the maximum diameter of the reticulum "windows") and the active one (due to the specific molecular interactions). The second function is the production of phagocytes. The endothelium is the greatest organism gland, both because of a great number of cells and their active surface. It controls the intensity of phagocytes production during infections. When ill, the endothelium becomes dysfunctional. In order to properly learn and apply the endothelium functions in the targeted drug delivery it is necessary to find out both the structure and functions of the endothelium. This knowledge is required to create such a method of drug delivery that the medicine, which is usually poisoning for healthy organism cells hits exclusively the infected organism cells, thanks to the endothelium signals. 26

27 SUBMARINE GAS PIPELINES SPREADING OF METHANE IN WATER Jan Hupka Gdansk University of Technology, Chemical Faculty, Department of Inorganic Chemistry, Narutowicza 11/12, Gdansk, Poland In principle, the way in which methane spreads in water is unknown. Undoubtedly, it depends on the gas release intensity. If a pipeline is damaged or bursts under water at a large depth, the gas plume will go through the sea surface by forming a funnel of bubbles (the funnel is about 30 m in diameter) at a flow speed of about 10 m/s. Some studies show that methane outflow forms a single large bubble or several bubbles. If the radius of a large gas bubble is comparable to or greater than the ship's hull, then the ship can sink. Sinking can occur because a mound of water forms above the bubble as it approaches the sea surface. A deep trough forms at either side of the mound and the water flow can carry the ship to one of the troughs. Whether or not a given ship can sink chiefly depends on its position in relation to the gas bubble. If it is situated far away from the bubble, the ship is in no danger. If it is situated exactly above the bubble, the ship is also safe, because being in a stagnant flow, the ship will not be sucked into the formed trough. The most dangerous position for the ship is between the stagnation point and the edge of the mound where the trough formed. When the ship is not at rest then it is able to move to a safe area by using its own power. Fig.1 Water and air circulation diagram for larger gas release 1.

28 SHAPE-DEPENDENT PHOTOCATALYTIC ACTIVITY OF DECAHEDRAL ANATASE TITANIA PARTICLES M. Janczarek, 1,2 E. Kowalska, 2 B. Ohtani 2 1 Gdańsk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk, Poland 2 Catalysis Research Center, Hokkaido University, Sapporo, Japan Single-crystalline anatase titanium(iv) oxide particles are technologically interesting for their semiconducting properties, e.g. in photocatalysis and photovoltaics. It was recognized in the previous research that decahedral anatase particles (DAPs) with exposed {001} and {101} facets exhibit the high level of photocatalytic activity [1-2]. It is well known that the photocatalytic activity depends on structural and physical properties of TiO 2. Therefore a relationship between properties and activity should exist. The problem is about the explanation of the intrinsic role of particle shape in this relationship. Gas-phase reaction process of TiCl 4 oxidation was proved to be an efficient method to prepare DAPs with a significant potential to process scale-up. The shape of anatase titania single crystal which determines the type of the exposed crystal facet, has been recently recognized as a potential key-factor of photocatalytic activity. The influence of main properties of DAPs on photocatalytic activity and reaction selectivity with a particular focus on the particle morphology have been analysed. The clarification of the role of particle shape is the key to understand the photocatalytic activity of anatase single crystal and to morphological control of photocatalyst with well-defined crystal facets. 1.

29 ANALYSIS OF COMBINED CYCLES Dawid Jędrychowski Gdansk University of Technology, Chemical Faculty, Department of Inorganic Chemistry, Narutowicza 11/12, Gdansk, Poland Poland has significant reserves of conventional energy sources, especially coal and lignite. We also have reserves of natural gas and shale gas prospectively. Status of mineral resources in Poland determine electricity production. There are many solutions to increase efficiency and minimize energy losses. One of these are combined cycles, which are a combination of the gas and steam turbine, where the heat from the exhaust gas is recovered and used in a steam circuit. This solution helps to reduce energy loss and increase the efficiency of the system by a few percent. On the basis of the actual total power efficiency of the system was determined. The resulting efficiency of the system was significantly higher than that obtained at each circuit separately. 29

31 ODOURS EMISSION FROM SELECTED FRACTIONS OF MUNICIPAL SOLID WASTES Izabela Konkol Gdansk University of Technology, Chemistry Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdańsk, Poland Advisor: Jan Hupka Aerobic and anaerobic degradation of bio-fraction of municipal solid wastes (MSW) involves production of biogas, emission of volatile compounds and odours. Environmental impacts of MSW processing depends on the quantity and characteristics of the organic fraction [1]. The aim of the work was to propose a new method of isolation of odorous compounds emitted from municipal solid wastes [2], based on the important of the temperature on the volatilization of organic compounds that depends on their vapour pressure [3]. In this regard, mixed municipal solid waste samples, collected before the sorting line and fraction mm, which is transported to the composting plant, were used mm fraction of MSW is obtained by separation on sieve drum and sorting in the cabin. Samples of waste fraction were collected by quartering. From each fraction five samples were taken for isolation organic compounds. After weighting, samples were dried under a slight vacuum. The temperature was increased from 60 C to 105 C. The vapors flow through the bulb placed in a salt-ice mixture. The water vapor and volatile compounds underwent condensation. Obtained in this way an aqueous phase was subjected to chemical analysis and the ph was determined. The greatest amount of condensate was obtained by drying mm fraction, while the average value for the mixed waste was 30% lower. Total organic carbon analyses show the greatest amount for fraction mm (1120 mg/l), it is 10 times higher than for mixed waste. 1. Scaglia B., V. Orzi, A. Artola, X. Font, E. Davoli, A.

32 INFLUENCE OF FROTHER TYPE AND ITS DOSSAGE ON FLOTATION OF CARBONACEOUS COPPER SHALE Przemyslaw B. Kowalczuk, Jan Drzymala Wroclaw University of Technology, Wybrzeze S. Wyspianskiego 27, Wroclaw, Poland Flotation is a physicochemical process commonly used to separate valuable from gangue materials utilizing differences in their surface properties. The surface properties can be characterized by different parameters, including contact angle of the air/solid/liquid system, surface tension, solids surface shape and roughness, zeta potential. These properties can be modified by using different chemical reagents, including flotation frothers. The role of frothers is to prevent a bubble coalescence and stabilize froth as well as to rapture the liquid film between the bubble and hydrophobic solid surface. In this work we investigated the influence of type and dosage of different frothers on a flotation performance of carbonaceous copper shale. It was found that all of the investigated in this work frothers, such as aliphatic alcohols, poly(propylene glycols), poly(propylene glycol) alkyl ethers and poly(ethylene glycol) alkyl ethers, can be used for flotation of carbonaceous copper shale. The high flotation recoveries suggested that the investigated frothers can act both as frothers, adsorbing at the liquid/gas interface, and as collectors, acting at the other two, solid/gas and solid/liquid, interfaces. To check this, the contact angle studies were conducted. The relationship between hydrophobicity, expressed as the receding and advancing contact angles, and frother dosage clearly indicated that the frothers do not change the contact angle of carbonaceous copper shale. It means that the investigated frothers do not adsorb at the solid/gas interface and do not act as collectors. A good flotation performance was caused by the influence of frother concentration on the thin liquid film (layer) stability between the hydrophobic solid and the bubble surface. 80 concentration, mg/dm P 3 C 3 P 3 concentrate yield, % C 6 C 4 P 3 C 1 P 3 C 4 E 3 C 6 E 2 C 4 E 1 C 2 E 2 C 11 C concentration, g/mg (Cx, CxEy, CxPy are symbols of frothers) This work was supported by the National Science Centre Research Grant (U-2012/07/D/ST8/02622). 32

33 TiO 2 NANOTUBES AS A PLATFORM FOR ELETRODEPOSITED POLIMERIC NANOSTRUCTURES Damian Kowalski UNIVERSITY OF REIMS CHAMPAGNE-ARDENNE, UFR Sciences Exactes et Naturelles Laboratoire de Recherche en Nanosciences (LRN), Campus Moulin de la Housse - Bâtiment 6, BP REIMS Cedex 2, FRANCE Anodic alumina oxide (AAO) nanoporous membrane is one of the most widely used hard template materials for synthesis of electrodeposited nanostructures. The secondary material is typically deposited in the pores of AAO forming nanowires of desired length and diameter. Recently, 1-D TiO 2 nanotubes become of high interest due to a very high degree of control over their geometry and functional properties arising from semiconductive nature of titania. 1 Herein we demonstrate a general approach for electrodeposition in TiO 2 nanotubes with conducting polymers as a model case. 2 By adjusting the current/potential protocols the polymer can be deposited either in free space in between nanotube walls and/or inside the nanotubes forming specific geometries between n-type inorganic semiconductor and p-type conducting polymer. The resulting polymer nanostructures are in the form of nanowires, nanopore arrays (Fig.1 left), and inverse-nanotube-array (Fig. 1 right). 3-5 The results will be discussed in view of potential application of the nanostructures.

Ohtani, 1 A. Markowska-Szczupak 3 1 Hokkaido University, Sapporo, Japan 2 Gdansk University of Technology, Gdansk, Poland 3 West Pomeranian University of Technology, Szczecin, Poland 4 Swinburne University of Technology, Hawthorn, Australia, Regarding catalytic and plasmonic properties of gold nanoparticles (NPs), the novel area of research on photocatalytic gold properties has been recently started. In contrast with catalytically active gold NPs, where nanosized gold is recommended [1], our results showed that polydispersity of deposited gold NPs on semiconducting support was beneficial for photocatalytic activity under visible light irradiation. It is thought that wide size/shape distribution of gold NPs, and thus the ability of absorption of light in a wide wavelengths range is responsible for the high level of photoactivity [2]. Though desirable absorption properties of plasmonic photocatalysts can be easily obtained by preparation of nanoparticles of different sizes and shapes, their photocatalytic activities under visible light irradiation are still low and should be enhanced. The improvement of photocatalytic activities under visible light irradiation was achieved by enlargement of interfacial contact between titania and NPs of noble metals, extension of photoabsorption ranges (by preparation of NPs of various sizes and shapes or composed of two kinds of noble metals [3]), and by deposition of noble metals NPs on faceted titania, i.e., octahedral (OAPs) and decahedral (DAPs). Plasmonic photocatalysts composed of titania and NPs of Ag, Au or Cu showed also high antiseptic properties under vis irradiation, due to possible synergism of antiseptic properties of noble metals and photodisinfection properties of photocatalyst. 1.

36 SELECTED TECHNOLOGICAL ASPECTS OF COPPER ORE ENRICHMENT PROCESS Katarzyna Księżniak, Witold Pawlos Gdańsk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdańsk, Poland Here I will describe an operation of Division of Concentrators, comprised of three ore enrichment plants, located in different mines but having separate organization structures. Ore processing facilities play a special role in copper ore production process. Their aim is to maximize the metal recovery and to produce concentrate with the quality parameters required by the smelters, at the lowest cost possible. All of the enrichment facilities use the same basic methods and processes, however, due to the varying quality of the ore, the facilities apply modified procedures such as sifting and crushing, milling and classifying, flotation, thickening and filtration, and drying. Efficient management of the processing plant requires knowledge of the detailed characteristics of the feed material for mineralogical, for example, release and association of minerals. Mineralogical analysis provides essential information on the optimization of technological processes, as well as the organization of production, and allows identification of the source of the irregularities. Recent studies of intermediates and products that have been performed using optical microscopy, are vague and unsupported by statistical analysis. It is expected that by the MLA will shorten the time of analysis, as well as will increase their accuracy. Systematically carried out the analysis will allow to build effective database and indication of the stage of the technological process in which losses occur. The advantage of this system is to generate improved and diverse information mineralogical and presence-based applications of simulation tools. 36

37 PDADMAC DEPOSITION STUDIES - QCM AND STREAMING POTENTIAL MEASUREMENTS Katarzyna Kubiak, Aneta Michna, Zbigniew Adamczyk, Krzysztof Jamroży Jerzy Haber Institute of Catalysis and Surface Chemistry, Polish Academy of Sciences, Niezapominajek 8, Cracow, Poland. The adsorption of polymers at solid/liquid interfaces is of a major significance for many practical and natural processes such as formation of nanocoatings on textiles, nano-encapsulation for controlled drug delivery and release, cell adhesion, protein and enzyme immobilization and separation. In this work, adsorption kinetics of the cationic polyelectrolyte poly(dimethyldiallylammonium chloride) (PDADMAC) having molar mass of 101 kg mol -1 on a surface of gold and mica was determined. Initially, the bulk characteristics of the polyelectrolyte were investigated using the DLS and micro-electrophoretic measurements which allowed one to determine the dependance of hydrodynamic diameter and zeta potentials on ionic strength at ph 5.8. Furthermore, the kinetics of PDADMAC adsorption were evaluated under in situ conditions using the streaming potential measurements and the quartz crystal microbalance (QCM-D). This allowed one to derive the calibration dependencies of the zeta potential on the polyelectrolyte coverage for various ionic strength successfully interpreted in terms of the 3-dimensinal (3D) electrokinetic model. Using these data, the PDADMAC desorption kinetics were quantitatively analyzed. In this way the desorption constants, the equilibrium adsorption constants and the binding energies of PDADMAC were determined, varied between and kt, for ionic strength of 10-3 and 0.15 M, respectively. These energies agree with the proposed model of discrete electrostatic interactions among ion pairs present at the polyelectrolyte chain and the substrate surface. The mean-field electrostatic interactions approach proved inadequate. The obtained results showed that PDADMAC monolayers can be widely used as an convenient platform for nanoparticle and protein immobilization.

38 SELF-ASSEMBLY OF NONIONIC SURFACTANTS IN IONIC LIQUIDS Anna Latowska, Justyna Łuczak Gdańsk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdańsk, Poland Self-assembly of amphiphiles in various solvents is a subject of increasing attention, however most of the described solvents, besides water, belong to volatile organic solvents [1]. Since ionic liquids were found to have remarkable solvation abilities, they were found to support micellization of some surface active agents. Four ionic liquids with 1-butyl-3-methylimidazolium cation, [BMIM], and tetrafluorobotate, [BF 4 ], hexafluorophosphate, [PF 6 ], bis(trifluoromethane sulfonylimide, [Tf 2 N] and trifluoromethanesulfonate, [TFO] anions, were examined for supporting micelle formation of three nonionic surface active agents, namely Triton X- 100, Triton X-114 and Tween 20. The presence of micellar aggregates in ionic liquid-surfactant solutions was examined by means of surface tension measurements in a pedant drop mode. Size of micellar aggregates was examined using dynamic light scattering technique. Obtained results allowed determination of adsorption and micellization parameters for the systems, which subjected micellization. Micellar aggregation was confirmed in the systems containing [BF 4 ] and [PF 6 ] anions in case of each of examined surfactants. In systems based on [BMIM][Tf 2 N] and [BMIM][TFO] ionic liquids no aggregates were detected in given experimental conditions. Such results indicate an influence of the anion type in the solvent on its ability to support micelle formation, therefore the presence of [BF 4 ] and [PF 6 ] anions does support the process, however [Tf 2 N] and [TFO] does not, in the applied conditions. 1.

39 CATALYTIC PROPERTIES OF Pd-Cu/Al 2 O 3 CATALYSTS IN THE LIGHT OF MUTUAL INTERACTION BETWEEN Pd AND Cu Magdalena Lesiak 1, Michał Binczarski 1, Izabela Witońska 1, Stanisław Karski 1 1 Institute of General and Ecological Chemistry, Lodz University of Technology, Poland Furfural is easily obtained from renewable sources (e.g.: corn cobs, wood, cotton hulls, straw) and the further processing leads to a useful from the chemical industry point of view products such as: furfuryl alcohol, tetrahydrofurfuryl alcohol, maleic acid, tetrahydrofuran, 2-methylfuran, 2-methyltetrahydrofuran, 5-methyl furfural [1]. The hydrogenation of furfural takes place mostly in the gas phase and conducting it in the liquid phase is a major challenge for the chemical industry. The reaction proceeds over chromium-copper catalysts in the liquid medium usually in moderate yield to furfuryl alcohol. The greatest drawback of cooper chromite based catalysts is their toxicity which causes severe environmental pollution [2]. Furfuryl alcohol is mainly used for the preparation of resins, phenolic resin modifiers, urea resins and a solvent. Furthermore, furfuryl alcohol is used in the preparation of tetrahydrofurfuryl alcohol, lysine, vitamin C, lubricants, dispersing agents and plasticizers [2]. The main by-product of the conducted reaction is tetrahydrofurfuryl alcohol, which is called a "green solvent" and like furfuryl alcohol is widely used in industry. The screening of catalysts 5%Pd/support (Al 2 O 3, TiO 2, C akt. ) was taken. Among the examined systems, the highest selectivity to the furfuryl alcohol was obtained on 5%Pd/Al 2 O 3 system. Bimetallic palladium-copper catalysts were deposited during the preparation step on Al 2 O 3. Bimetallic catalysts contain always 5wt-% Pd and respectively 1.5, 3 and 6wt-% Cu. For comparison, the monometallic 5%Cu/Al 2 O 3 catalyst was used in studied reaction. Reactions of furfural (0.1 M) reduction were performed in a high-pressure batch reactor (Parr) with the using of constant amount of catalyst (0.5 g), hydrogen pressure (20 bar), temperature (90 C) and volume of furfural (25 ml). The process was carried out for 2 hours. On the basis of obtained results, it was found, that the catalysts containing Pd in their composition are more active than the monometallic copper system in the reaction of furfural reduction. However, an increase in the concentration of Cu in the bimetallic supported systems on the base of palladium results in lower selectivity to tetrahydrofurfuryl alcohol. For the bimetallic catalysts the X-ray study (XRD), temperature-programmed reduction of H 2 (TPR H 2 ) and carbon monoxide chemisorption (FTIR), were performed. The results show that the metals are alloying in the bimetallic systems, wherein stoichiometry of the alloys depend on the quantity of introduced copper. The formation of the alloys is probably connected with the further reduction of furfural to furfuryl alcohol. The addition of copper into palladium catalysts leads to the decreasing of yields of ring hydrogenation product as tetrahydrofurfuryl alcohol. 1. Win D.T., Furfural - Gold from Garbage.

40 INVESTIGATION OF BARRIER AND ADHESION MECHANISMS OF ANTICORROSION COATINGS USED FOR LESS PRECISELY PREPARED SURFACE Milena Lewińska, Andrzej Miszczyk, Kazimierz Darowicki Gdansk University of Technology, Chemical Faculty, Department of Electrochemistry, Corrosion and Materials Engineering, Narutowicza 11/12, Gdansk, Poland Corrosion processes occurring on the surface of steel can lead to significant structural damage. In order to protect constructions of transmission towers against corrosion coating systems are used. Over long term exposed to atmospheric condition renovation of paint system needs to be carried [1-3] Due to the function and location of the transmission towers, environmental and economic aspects, renovation process must meet specific requirements for surface preparation processes, the selection of appropriate coating system and its application. Coatings systems especially designed for less than ideal conditions from different paint producers were applied over long-term exposed to atmospheric conditions on carbon steel, galvanized carbon steel (without and with steel corrosion products) and weathering steel. Generally, properties of the protective paint systems are determined by the barrier and adhesion mechanisms. Determination of the barrier properties of paint systems is possible through the use of Electrochemical Impedance Spectroscopy (EIS) [4]. The mechanism of adhesion is determined by measuring the adhesion strength of a paint system to the surface [3]. Initial and wet adhesion, as well as, barrier properties were tested [5]. For this purpose the thermal shocks that model changes in real conditions were used [6]. This procedure allows to evaluate the properties of paints and select such coating system that would be appropriate for less precisely prepared surface 1. ISO ISO ISO Barsoukov E. and J.R.

41 CHARACTERIZATION AND TECHNICAL APPLICATION OF FINE PHOTOCATALYTICAL PARTICLES A STUDY OF THE IMMOBILIZATION OF PHOTOCATALYSTS Marek Lieder, Andreas Hänel Gdansk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk, Poland Environmental pollution, global warming, and fossil fuel shortening are current and urgent problems of the humanity. Photocatalysts are promising materials for the decomposition of pollutants in the gaseous and aqueous phase, for the generation of hydrogen by water splitting, for utilization in dye sensitized solar cells or in the photoconversion of carbon dioxide to low-molecular hydrocarbons. TiO 2 is one of the most investigated photocatalysts, since it is chemically inert and easily available. The technical and large-scale application of photocatalysis is not satisfactorily realized yet, since several unsolved problems exist. The first problem is that TiO 2 exhibits a band gap of 3.2 ev, which corresponds to a radiation wavelength of 388 nm (UV-A). Solar light consists only of 3 6% UV radiation. Secondly, the majority of conducted research investigated the decomposition of single compounds in laboratory scale. However, in technical applications large amounts of diversity of compounds need to be decomposed in a certain time, whereas the reactions can influence each other. Furthermore, large surface areas of the photocatalysts are required for high photocatalytic activity. Thus, photocatalysts are commonly applied as nanoparticles, whereas they have to be cumbersomely separated downstream of the process. Immobilization of photocatalyst particles would be advantageous, so it could be reused several times. However, immobilization methods like dip-coating, sol-gel, whipping, spraying or cluing were insufficient and unsatisfactory [1]. Thus, a better immobilization method is required. Electrochemical preparation (especially cathodic deposition) of photocatalysts with simultaneous immobilization has been barely considered. Nevertheless, it is proposed that electrochemical deposition offers several advantages in comparison to other methods, like low preparation costs, easiness, and control of the deposited film thickness. 1.

42 STUDIES ON FORMATION AND PERCOLATION IN IONIC LIQUIDS/TX- 100/WATER MICROEMULSIONS Justyna Łuczak Gdańsk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdańsk, Poland The subject of ionic liquids (ILs) has generated interest since many of them have negligible volatility, wide liquid regions, exhibit significant conductivity, favorable solvating properties, and thereby may be an alternative to traditional solvents. Application of these compounds as one of the phases in aqueous and nonaqueous microemulsions is an example of subjects of increasing attention. Ionic liquids may not only play a role of a polar phase but also of an organic solvent [1-3]. This second application is probably a more promising possibility from a green chemistry point of view due to elimination of the volatile organic solvents being a nonpolar part of microemulsions. Ternary microemulsion systems of H 2 O/Triton X-100/[BMIM][Tf 2 N], and H 2 O/Triton X-100/[BMIM][PF 6 ] were prepared, compared and characterized for phase behavior for different water/surfactant ratios, at 25 o C. It was found that a change of an anion structure in the ionic liquids determines the total monophasic area of the systems. A liquid crystalline mesophase was detected in H 2 O/Triton X-100/[BMIM][PF 6 ]. The microemulsion domains were identified by means of conductivity, viscosity and dynamic light scattering measurements. An increase in water mass fraction resulted in an increase of electrical conductivity of both systems, however not as rapid as in typical microemulsion systems. The conductivity data were analyzed in terms of percolation theory, and it was revealed, that the theory may be adopted only partially. The variations of the dynamic viscosity of surfactant/il mixtures, as a function of water mass fraction along the experimental dilution lines, differs significantly from typical solvent based microemulsions. The size of water/ils microemulsion droplets, measured by dynamic light scattering, is nearly independent from the content of water. 1.

43 WATER QUALITY AND FLOTATION OF LGOM COPPER ORES Andrzej Łuszczkiewicz, Jan Drzymała Wroclaw University of Technology, Wybrzeze Wyspianskiego 27, Wroclaw, Poland Physico-chemical properties of water used in technological applications are very important factors affecting flotation used for upgrading of ores and raw materials. Water applied for industrial enrichment of copper ores at KGHM Copper S.A. in Poland is a mixture of mine and recycled waters coming from a tailing pound. The waters contain a substantial load of soluble salts, mainly NaCl and some sulfates as well as organic matter. Water from the Żelazny Most tailing pound contains from 23 to 33 g/dm 3 of salts while mining water up to 250 g/ dm 3. As a result, the flotation waters contain from 20 to 50 g/dm 3 of soluble matter, depending on the flow sheets of the Copper Ore Concentrator. The presentation discusses an influence of water quality on flotation of copper ores processed by the Lubin, Polkowice and Rudna Concentrators. It was found that dilution of industrial water with tap water sometimes improves flotation while water made more mineralized by evaporation of industrial water clearly deteriorates flotation results. It was also determined that purified with activated carbon industrial water also leads to worse flotation results while adding NaCl to industrial water does not alter the selectivity of flotation Cu and Corg while it decreases the selectivity of flotation of Ag and Pb component of the ore. It was concluded in the presentation that a slow increase of NaCl content in industrial waters with years of KGHM operation should not impact upgrading. However, a presence of an unknown organic substance which decreases selectivity of flotation is harmful for the flotation process and its identity should be establish possibly soon.

44 ADVANCED OXIDATION PROCESSES IN WATER RECYCLING RESULTING FROM HYDRAULIC FRACTURING Joanna Mioduska Gdansk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk, Poland Advisors: Jan Hupka/Anna Zielińska-Jurek Water is the main component of the fracturing fluid, which is injected into the shale formation to increase permeability of the rock and to unblock the movement of gas or oil residing within the structure. Hydraulic fracturing requires a large quantity of fresh water, which in Pomerania should be taken from surface reservoirs. After the completion processes, water partially returns to the surface as so-called flowback water. The returning fluid has already changed composition, due to rock leaching and blending with reservoir water, which causes transfer of soluble compounds into the aqueous phase. The flowback water usually contains elevated amount of total dissolved solids (TDS), total suspended solids (TSS) as well as metals such as barium, strontium, and calcium, and naturally occurring radioactive materials (NORMs), which may be present sometimes in concentrations raising concern. It may also contain nitrite, sulfate, other metals, and organic compounds including ethers, ketones, trihalomethanes, aromatic hydrocarbons and polycyclic aromatic hydrocarbons. Due to the use of up to m 3 of water per 1 km of horizontal section of the well, a new methods of water treatment are being developed. Wastewater purification may involve pre- and advanced- treatment. As far as advanced methods are concerned they may refer to the improvement of biological or physicochemical properties. The method that drew my attention refers to the heterogeneous photocatalytic degradation, which is related to one of advanced oxidation processes. Photocatalysis has been successfully used for effective treatment of water polluted with toxic substances. During irradiation at appropriate wavelength, free electrons with corresponding holes form on the surface of the photocatalyst. Due to theirs ability to react with water or oxygen, hydroxyl or superoxide anion radicals are formed. These moieties have strong oxidizing properties and are able to break down organic compounds into carbon dioxide and water. One of the most commonly used photocatalyst is titanium dioxide, however, it is active mostly in the UV light. Its activity can also be triggered in visible light, which requires modification of its surface. In this regard, titanium dioxide was modified by adding transition metal into the structure. Such modifications offer the possibility of enhanced oxidation of organic pollutants present in the flowback water from fracturing processes. 44

45 RELATIONSHIP BETWEEN MUD LOGGING AND WELL LOGGING DATA IN BALTIC BASIN BOREHOLES Anna Mykowska Gdansk University of Technology, Chemical Faculty, Department of Chemical Technology, Narutowicza 11/12, Gdansk, Poland Advisor: Jan Hupka GR NPHI LLD RHOB Well logging and mud logging data can be the basis for the evaluation of geological formations. The data are also used in drilling process control and to ensure safety during work on the borehole. The aim of the paper is to investigate the results obtained from well logging and mud logging from two exploration boreholes in Baltic Basin. Four major types of logs: gamma ray (GR), bulk density (RHOB), compensated neutron (NPHI) and resistivity (LLD dual laterolog, long distance resistivity) were analyzed and compared with respect to stratigraphy. The next step was to make a reference of these parameters to the lithological structure obtained from mud logging. This allows to correlate the depth of geological levels in different boreholes which can be used for subsequent drilling. The comparison can partially replace core analysis, giving direct information about lithology and gas hydrocarbons. Information provided this way has a lower degree of reliability than the data from core analysis however utilitarian objective of the research is an economical aspect - saving expenses of coring while maintaining the maximum possible information about reservoir. Due to the fact that the Precambrian crystalline substrate is shallower in the area of geological elevation and deeper in the area of syneclise, the difference between the depth of the geological layers in the discussed boreholes can be observed. Gamma ray logs correspond to lithology obtained from mud logging. Fig. 1 Selected well logs from Baltic Basin borehole 45
