9 PLENARY SESSION PLENARY I QUANTUM CONTROL AT THE NANOSCALE: MANIPULATING ELECTRONS FOR QUANTUM INFORMATION Mario F. Borunda Oklahoma State University, Stillwater, OK, USA Keywords: Quantum Control, Quantum Information, Nanostructures. The quest for solid-state quantum computing in semiconductor nanomaterials has led to break through in the initialization, processing, and readout of single- and two-particle states in coupled quantum dots. Fast and accurate control of electronic states is a key requirement for solid-state quantum information processing.i will present theory and calculations for coherent high-fidelity quantum control of many-particle states and for the local control of electronic charge. Coupling a two-electron double quantum dot to a terahertz optical source enables targeted excitations that are one to two orders of magnitude faster and significantly more accurate than those obtained with electric gates. I will also present the idea of local optimal control theory as a powerful approach to find optimized gate voltages that induce coherent transitions between electronic states. The proposed schemes achieve (i) faster operation time and (ii) limits the frequencies used in the control fields to the experimentally accessible range, while maximizing the fidelity of the processes. The ability to coherently control arbitrary twoelectron states to maximize their entanglement and coherently manipulate charge states opens up further opportunities in nanoscience and represents a clear advancement in solid-state quantum information. PLENARY II CORRELATION BETWEEN PARTICLE SIZE AND SINTERING BEHAVIOR OF NANOPOWDERS Olivia A. Graeve Olivia A. Graeve,2,a, James T. Cahill,,b Hoorshad Fathi, 2,c James P. Kelly,2,d Department of Mechanical and Aerospace Engineering, University of California, San Diego 9500 Gilman Drive MC 04, La Jolla, CA , USA 2 Kazuo Inamori School of Engineering, Alfred University,Pine Street, Alfred, NY 4802, USA a b c d

10 Keywords: Triboluminescence, nanopowders, coatings, crack detection, combustion synthesis, structural health monitoring. We present an overview of fundamental responses and limits of precipitation processes for the synthesis of nanostructured ceramic nanopowders, with special emphasis on combustion synthesis for the preparation of borides and reverse micelle synthesis for the preparation of oxides. Advanced sintering techniques for nanostructured materials will also be described and a correlation between powder particle size and sintered grain size will be presented. Boride compounds have proven essential for myriad applications such as reinforcing phases in metal-matrix composites and armor materials. One particular sub-group in this large class of materials includes the hexaborides. We will demonstrate the first instance of the preparation of boride materials by the efficient combustion synthesis technique at a temperature of 320 C. We will also present an analysis and systematic investigation of the structure and stability of reverse micelle systems with the addition of NH 4 OH, ZrOCl 2, and Al(NO 3 ) 3 salts. The concept of an electrical double layer, as it applies to reverse micelles, will be considered for explaining features of destabilization, including the initial decrease in reverse micelle size, the destabilization concentration, and the effect of cation valence. We propose that the reduction in size prior to instability is caused by compression of the reverse micelle electrical double layers, as higher concentrations of salts are present. All these effects have important implications for the preparation of nanopowders by reverse micelle synthesis. If the reverse micelles are unstable before the precipitates are formed then the advantage of reverse micelle synthesis is immediately lost. PLENARY III STUDIES OF SUPPORTED NOBLE METAL NANOPARTICLES FOR SUSTAINABLE FUELS PRODUCTION Alexander Orlov,a, Peichuan Shen, Yan Li 2 and Shen Zhao Materials Science and Engineering, Stony Brook University, Stony Brook, NY 794, USA 2 Computational Science Center, Brookhaven National Laboratory, Upton, NY 973, USA Keywords: Nanoparticles, catalysts, photocatalysis, noble metals Understanding the role of noble metal nanoparticles in production of H2 under light under solar light is a growing area in sustainable energy research. Although there are numerous studies of using these metals as co-catalysts, the issues related to a size range where they lose their metallic properties is a very promising area of investigation. In this study we combine experimental studies of primarily Pt based 2

11 catalysts with DFT calculations, where we explore the issues related to shape and size of these nanoparticles. More specifically, we utilize microscopy, spectroscopy and reactor studies to understand the advantages of using nanometer and sub-nanometer particles for photocatalytic water splitting and water gas shift reactions. The results obtained for Pt nanoparticles will be compared to data obtained for other noble metal catalysts. PLENARY IV PROCESSING OF NANOCRYSTALLINE TRANSPARENT CERAMICS FOR PHOTONIC APPLICATIONS E. H. Penilla, A. T. Wieg, C. L. Hardin, Y. Kodera and J. E. Garay a Materials Science and Engineering Program and Mechanical Engineering University of California, Riverside Keywords: Photonic materials, ceramics, nanocrystalline. It is well known that microstructure can significantly affect the optical properties of polycrystalline ceramics. For example, holding the grain and pore sizes to length scales less than the wavelength of light can be significantly increase transparency. Recently, the versatile material processing technique of current activated pressure assisted densification (CAPAD), often called Spark Plasma Sintering (SPS) has been gaining momentum as a tool for producing optical ceramics. The primary reason is that CAPAD is especially effective in overcoming the grain growth challenge. Additionally, there is now evidence that the technique is capable of producing non-equilibrium ceramics, i.e. materials that cannot be made using conventional sintering. The method draws its effectiveness from large electric current densities that serve to heat the materials and can also alter the processing kinetics. After an overview of our processing techniques, we will present results from ongoing work on tailoring the optical properties of oxide and nitride ceramics. We will discuss results showing improved visible light transmittance and luminescence and will also show efforts on fabricating near net shaped ceramics. 3

12 PLENARY V ENABLING CHEMICAL DISCOVERY THROUGH THE LENS OF A COMPUTATIONAL MICROSCOPE Rommie E. Amaro a 3234 Urey Hall, La Jolla, California, , United States Keywords: molecular biophysics, drug discovery, rational design, cancer, p53 With exascale computing power on the horizon, computational studies have the opportunity to make unprecedented contributions to drug discovery efforts. Steady increases in computational power, coupled with improvements in the underlying algorithms and available structural experimental data, are enabling new paradigms for discovery, where in computationally predicted ensembles from large-scale biophysical simulations are being used in rational drug design efforts. Such investigations are driving discovery efforts in collaboration with leading experimentalists. I will describe our work in this area that has provided key insights into the systematic incorporation of structural information resulting from stateof-the-art biophysical simulations in to protocols for inhibitor and drug discovery, with emphasis on the discovery of novel druggable pockets that may not be apparent in crystal structures. PLENARY VI NANOTECHNOLOGY DERIVED STRATEGIES AS POTENTIAL TREATMENTS FOR CENTRAL NERVOUS SYSTEM TUMORS Milan Makale University of California San Diego, Moores Cancer Center, 3855 Health Sciences Drive Keywords: Radiotherapy; nanoparticle; cancer. La Jolla, CA, USA, Standard chemo-radiotherapy falls far short in the most common and lethal forms of brain cancer in adults and children. These tumors are often distressingly resistant to radiation and chemotherapy, and these standard protocols induce profound life-long morbidity in the few surviving patients. We believe there are two key issues in translational brain cancer research which are linked to the stubborn resistance of this tumor; () potent anti-tumor agents able to overcome resistant brain tumors in culture have fared poorly in preclinical development because of pharmacokinetic, toxicity, and targeting limitations, and (2) megavoltage radiotherapy of the brain and spinal cord is an extremely useful 4

13 mainstay and palliative measure, but the required doses are too high, causing severe normal tissue damage. PLENARY VII IN-VITRO SELF-ASSEMBLED PLANT VIRUS-LIKE PARTICLE VECTORS FOR MAMMALIAN CELLS Charles M. Knobler Department of Chemistry and Biochemistry, University of California, Los Angeles, CA USA Keywords: In vitro assembly, plant viruses, RNA packaging, gene delivery The Cowpea Chlorotic Mosaic Virus consists of a protein shell called the capsid made up of 80 identical proteins that surrounds and protects the genome, 3,000 nucleotide-long single-stranded positivesense RNA. Remarkably, the virus is capable of self-assembling when the pure RNA and pure protein are mixed in an appropriate buffer solution. More remarkable still, the capsid can assemble around non-viral RNAs, ranging in length from 00 to 0,000 nt, as well as anionic polymers, quantum dots and nanoemulsion droplets. This capacity to package a wide variety of cargoes can be utilized for delivery of genetic information to cells as demonstrated by recent experiments [Azizgolshani, et al. Reconstituted Plant Viral Capsids Can Release Genes to Mammalian Cells, 203Virol. 44, 2 7] that this plant virus can be employed for transfection of mammalian cells. PLENARY VIII ON THE ORIGIN OF INCOMPLETENESS IN IMMATURE HIV-GAG PARTICLES Bogdan Dragnea Chemistry Department Indiana University Bloomington, IN 47408, U.S.A. Keywords: Self-assembly, HIV, virus assembly, nanoparticle, electron microscopy. To understand and interfere with the stages of the virus life cycle, knowledge of the structural properties of viruses and their assembly intermediates is required. A case in point is the human immunodeficiency virus type (HIV-), which, despite intense study, still presents challenges coming from a limited knowledge of its architecture and the transformations associated with its passage from the noninfectious immature state to the infectious mature state during the viral life cycle. An intriguing feature of the immature HIV- is the sizable gaps in its protein lattice observed by electron microscopy. The origin of the gaps is not understood but they may be important for the timing of release of the viral 5

14 particle from the cellular membrane before assembly is completed. We hypothesize that the gaps are unavoidable consequences of the high aspect ratio of the protein subunits constrained to assemble on a spherical shell. We present experiments testing this hypothesis by nanoparticle directed assembly. PLENARY IX HT SINGLE PHASE MULTIFERROICS José Antonio Eiras Universidade Federal de São Carlos - Departamento de Física Grupo de Cerâmicas Ferroelétricas - CEP São Carlos - SP Brazil a, b, c Keywords: Magnetoelectric coupling (ME). In the last decade, intensive research efforts have been devoted to produce magnetoelectrics materials viewing to improve the electric control of the magnetization and vice-versa at high temperatures. Among the materials with potential characteristics to present improved magnetoelectric coupling (ME) arise the single phase multiferroics (SPM), that present the coexistence of electric and magnetic ordering below characteristics temperatures. The cross-coupling between the magnetic and electric orders parameter, termed magnetoelectric coupling, brings novel physical phenomena and offers potential ability to control or sense the material polarization or magnetization states with either magnetic or electric field. This opens possibilities to develop devices (transducers, sensors, actuators ) for new technological applications. The main challenge for practical application of SPM lies in the difficulty to obtain materials with multiferroics characterisitics around room temperature. Typical lead based perovskites that can present multiferroics ordering are Pb(Fe /2 Nb /2 )O 3 and Pb(Fe 2/3 W /3 )O 3. Reports related to these materials attributed the magnetic ordering to the Fe 3+ ions, while the ferroelectric ordering was related to the W 6+ or Nb 5+ ions. In this presentation experimental results of Pb(Fe /2 Nb /2 )O 3 and (- x)pb(fe 2/3 W /3 )O 3 xpbtio 3 (PFWPT) (0 x 0.30) ceramics, viewing to the establishment of the magnetoelectric coupling around room temperature will be presented. The temperature intervals where ferroelectric or magnetic ordering occurs and coexists and the characteristics of the magnetoelectric coupling were investigated through magnetic, dielectric spectroscopy and anelastic measurements as a function of the temperature. Evidences of changes in magnetic ordering (above 500 K) and the presence of magnetoelectroelastic anomalies (in the temperature range of 200k to 300 K), will be discussed. 6

15 PLENARY X INTEGRATION OF FUNCTIONAL OXIDES WITH SEMICONDUCTORS Ravi Droopad, a, R. Contreras-Guerrero, Hanu Arava, J. Rojas Ramirez, Robert Klie 2, Jeremy Levy 3, Byounghak Lee Ingram School of Engineering, Texas State University, San Marcos, TX Dept. of Physics, University of Illinois-Chicago, Chicago, IL Dept. of Physics and Astronomy,University of Pittsburgh, Pittsburgh, PA Dept. of Physics, Texas State University, San Marcos, TX Keywords: Epitaxial oxides, molecular beam epitaxy, semiconductors. Oxides have played an important role in the creation of the transistor leading to the proliferation of modern day consumer electronics. In this application the oxide layer is amorphous, act as a dielectric with low leakage, and has a high quality interface that is only possible with silicon. Crystalline oxides on the other hand possess rich and diverse properties that can be exploited to create novel functional devices when integrated with other semiconductors. One such example is the use of ferroelectric layers to perturb the 2 dimensional electron gas channels in III-V semiconductors leading to reconfigurability of high speed optoelectronic devices. Another is the use of magnetic layers on semiconductors to fabricate spin transport devices and novel non-volatile memories. However the challenge is the integration of these crystalline oxide materials, and controlling the interface quality, with semiconductors. With the recent advances in oxide molecular beam epitaxy, high quality functional oxides with near perfect interface can now be grown. In this presentation, I will outline the growth of these crystalline oxides on both silicon and GaAs which demonstrate functionality. Bonding chemistry at the oxide/semiconductor heterointerfaceis also investigated in an attempt to understand the atomic structure of such interfaces. PLENARY XI NANOSCALE EFFECTS ON THE MECHANICAL PROPERTIES OF BIOLOGICAL MATERIALS Joanna McKittrick Department of Aerospace and Mechanical Engineering and Materials Science and Engineering Program University of California, San Diego, 9500 Gilman Dr., La Jolla, CA 92037, USA Keywords: Biological materials, mechanical properties 7

16 Structural biologicl materials such as mollusk shells and bone are light weight, strong and fracture resistant. Due to the hierarchical structure of these materials, each level presents a strengthening and toughening mechanism. At then at nanoscale, features such as sacrificial bonds, bridges and viscoelastic stretching are present. This presentation will discuss how these features operate and interact to result in these extraordinary properties of biological materials. PLENARY XII WHAT IS NEXT IN HIGH RESOLUTION ELECTRON MICROSCOPY IN NANOTECHNOLOGY? Miguel JoseYacaman University Of Texas at San Antonio, PhysicsDepartment Modern electron microscopy has achieved an old dream to break the A resolution barrier. Indeed Microscopes such as the ARM in UTSA have a resolution of 0.8 A (80 pm) that can be achieved in a routine basis. Our microscope was the number one in the world until recently the DOE center at Berkeley achieved 0.5 A. In real terms since the size of the atom is in that range (Helium atom is 40 pm) it means that the resolution that we have achieved is the limit of can be achieved. Below the nuclear interactions will dominate and other phenomena will dominate. So what is the Future of Electron Microscopy? It can be say that from now on all the improvements will be not in resolution but in other areas. In this talk we will review the most significant areas of nanotechnology that demand significant improvements in Electron microscope techniques. Some examples are the need of more accurate in situ experimentation and measurements, single electron detection, need of low voltage and many others. PLENARY XIII COMMERCIALIZATION OF NANOTECHNOLOGY INNOVATION AT UNIVERSITY: CONCEPT TO PRODUCT Bhabendra Pradhan CTO, Nanoholdings LLCcountry Rowayton, CT, USA Keywords: List the keywords that best describe the contents of your paper. One of the biggest challenges for our society is to find ways provide energy needed for our growing demand, and at the same time preserves our eco-system. Nanotechnology can contribute a 8

17 positive development in this direction in several ways. University s leading scientists invent many new technologies at universities laboratory. Of ten university inventions fall in the innovation gap which refers to the difficulty of obtaining capital to develop the technology further for commercialization or materializing these new concepts into a viable product. This talk will discuss finding promising new university innovations and starting new companies to develop and commercialize them. Nanoholdings is a company whose business model is to fill this gap for energy and wáter related nanotechnologies. Several examples will be discussed which represent technology developments and commercialization at different university worldwide that have enormous potential. PLENARY XIV OXIDE AND II-VI MATERIALS ENABLING NOVEL DEVICES FOR FLEXIBLE AND LARGE AREA ELECTRONICS Manuel Quevedo Department of Materials Science and Engineering, University of Texas, Dallas Keywords: Radiation detectors, II-VI, Thin Film Transistors, Electrical Performance Low temperature device technologies that have enabled flexible displays also present opportunities for flexible electronics and flexible integrated systems. Of particular interest are possible applications in flexible, low metal content, sensor systems for unattended ground sensors, smart medical bandages, electronic ID tags for geo-location, conformal antennas, neutron/gamma-ray/x-ray detectors, etc. In this talk, our efforts to develop novel inorganic semiconductor materials based on oxides and II-VI systems for novel CMOS integration schemes, circuits, memory, sensors as well as advanced metal contacts, dielectrics and semiconductors for flexible electronics are presented. In particular, we discuss fundamental materials properties including crystalline structure, interfacial reactions, doping, etc. defining device performance and reliability of inorganic oxides and II-VI materials. Materials characterization methods including RBS, XPS, XRD, etc. are used to analyze materials deposited by pulsed laser deposition, chemical bath deposition and inkjet printing. With the materials developed here thin film transistors (TFTs) with mobility s as high as ~30 cm2/v s, Ion/Ioff of ~09 and VT shift of less than ~0. ev are demonstrated. To achieve these TFTs characteristics, a variety of contact materials, gate dielectric, annealing conditions and device structures were studied. The factors affecting VT instability are also presented and correlated to electrode materials, gate dielectric, and post-annealing conditions. In short, TFT instability is correlated to traps and impurities at the dielectric/semiconductor and/or semiconductor film. In addition, integration of these TFTs in CMOS circuits is demonstrated. In particular, a variety of logic gates and FRAM memory cells are demonstrated. The feasibility of II-VI and oxides for flexible 9

18 and transparent devices as well as novel radiation sensors is discussed. Finally, we demonstrate an integrated neutron sensor fully fabricated at UT-Dallas that includes wireless communication to a mobile device.) PLENARY XV PHASE STABILITY IN MULTILAYERED THIN FILMS Raymundo Arróyave,2,a, Anchalee Junkaew,b,Byoungsoo Ham 2,c, Department of Materials Science and Engineering, Texas A&M University, USA 2 Department of Mechanical Engineering, Texas A&M University, USA c Keywords: Nano-films, phase stability, thermodynamics On the basis of the underlying thermodynamic constraints, phase stability of constituents in metallic multilayer thin films can be markedly different from the stability of the same material in bulk form. In the absence of size effects, metastable (and even unstable) phases can only be stabilized in bulk form under further constraints, such as elevated-pressures and temperatures. On the other hand, interfacial effects resulting from the growth of nanolayer systems has been shown to stabilize these metastable phases under ambient conditions, albeit under coherency constraints arising from the epitaxial growth of these films. The stabilization of these so-called pseudomorphic phases results from the competition between bulk and interfacial contributions to the free energies of the multilayer systems. In this work, a classical thermodynamic approach has been used for describing the pseudomorphic growth in Mg/Nb multilayer films. The bi-phase diagram of these films has been predicted theoretically and the predictions were verified experimentally by growing multiple Mg/Nb thin films that were characterized through high resolution transmission electron micrograph (HRTEM) and X-ray diffraction (XRD) measurement. The good agreement between predictions and experiments shows that the stability of multilayer films can be explained through simple thermodynamic analysis on the competition between bulk and interfacial energies.

19 O-00 FTIR study of benzyl alcohol and benzaldehyde adsorption on Au/Ce-Al-O catalysts Elena Smolentseva, a, Sergey Beloshapkin 2,b, Elena V. Gusevskaya 3,c, Sergio Fuentes,d and Andrey Simakov,e Universidad Nacional Autónoma de México, Centro de Nanociencias y Nanotecnología, km.07 carr. Tijuana a Ensenada, C.P , Ensenada, B.C., México 2 Materials & Surface Science Institute, University of Limerick, Limerick, Ireland 3 Universidade Federal de Minas Gerais, Belo Horizonte, MG, Keywords: Gold catalysts, FTIR, benzyl alcohol, benzaldehyde. The oxidation of alcohols is an important goal for synthetic organic chemistry. Gold catalyzed oxidation of alcohols, which involve O2 as an oxidant, is a good option because it is cheap, safe and produces only water as a by-product. The catalytic efficiency of gold catalysts depends on the size of Au nanoparticles and the affinity of the support to stabilize key reaction components. The present work was dedicated to the FTIR study of benzyl alcohol and benzaldehyde adsorption on the gold catalysts supported on Ce-Al-O mixed oxides, alumina and ceria as well. Gold catalysts (3 wt.%) were prepared by deposition-precipitation with urea and activated in oxygen or in hydrogen at 350ᵒC. Samples were characterized by FTIR, XPS, in situ UV-Visible spectroscopy and TEM. It was revealed that the nature of adsorbed complexes and their stability are determined by the nature of supports and type of catalyst redox pretreatment. The data obtained are in a good correlation with the catalytic activity and selectivity of these gold catalysts in aerobic oxidation of benzyl alcohol. The authors thank to E. Flores, P. Casillas, V.García, F.Ruiz, E.Aparicio, M. Sainz and J. Peralta for their kind technical support in this work.

20 2 Centro de Nanociencias y Nanotecnología, Universidad Nacional Autónoma de México (CNyN- UNAM), Ensenada, BC, 22860, México. a Keywords: Nanoreactors, Encapsulation, Au-Pd nanoparticles, Nitrophenol, SiO 2 and ZrO 2. In the last few years, the encapsulation of catalytically active nanoparticles with formation such structures as nanoreactors has become very attractive due to their high stability against the reaction conditions. In order to enhance the catalytic performance of these nanoreactors, the encapsulation of bimetallic nanoparticles has been proposed. The nanoreactors based on Au-Pd nanoparticles are very promising because these nanoparticles are characterized with high efficiency in the multiple reactions of fine and environmental chemistry. However, till now only Au-Pd encapsulated in silica 2 ) and tested in CO oxidation have been reported. On the other hand, the reduction of nitrophenol into aminophenol, the most common reaction for test of nanoreactors, is relevant by two main reasons: (i) hydrogenation of nitro-compounds helps with the environmental pollution; and, (ii) the product, aminophenol, is useful in pharmaceutical industry and photographic. Therefore, here is reported the design of 2 nanoreactors with yolk shell structure and test of their activity in the catalytic reduction of nitrophenols. The proposed 2 nanoreactors, successfully prepared via the traditional bottom-up route, were characterized with a mono dispersion of Au-Pd cores inside the inorganic shells. The porous structure of the ZrO 2 shells allows free transport of nitrophenol and aminophenol during the reaction. Partial covering of Au core with Pd significantly improved catalytic activity of nanoreactors. Consequent catalytic runs revealed superior stability of 2 nanoreactors compared to the reference AuPd/ZrO 2 catalyst. To the best of our knowledge this is the first study of 2 nanoreactors. The authors would like to thank O. Callejas, M. Vega, E. Flores, F. Ruiz, J. Peralta andm. Sainz for technical assistance.
