6 Mercado mundial de nanorrevestimientos anti-huellas, anti-bacterianos, anti-incrustantes y auto-limpiables Publicada en The Vertical Markets Research Portal, 08/16/2012. Nanocoatings are routinely applied to a wide variety of substrate materials (plastics, glass, metals, ceramics and textiles). Due to the properties inherent at the nanoscale, the coatings are typically multifunctional, exhibiting one or combinations of the following properties: scratch and abrasion resistance, anti-static, oleophobic, easy-to-clean, antireflective, anti-microbial activity, sensor and catalytic activity. NOTICIAS La nanotecnología ayuda a los fabricantes de alimentos a hacerlos más saludables Publicada en foodmanufacture.co.uk, 08/01/2012. UK food manufacturers have been urged to recognise the massive potential of nanotechnology in creating healthier foods. Tiny nano particles can deliver a more rapid hit of taste, thus enabling ingredients such as fat and salt to be reduced in recipes, which also reduces the cost of ingredients, Barry Park, theme manager at nanotechnology promotion body Nanotechnology Knowledge Transfer Network (NanoKTN), told FoodManufacture.co.uk. Estudios sugieren a los xilanos como sustitutos del almidón en los bioplásticos del futuro Publicada en foodproductiondaily.com, 08/01/2012. A new Finnish study suggests that xylans and mannans, plant cell wall polysaccharides derived from agricultural and forestry sidestreams, could replace starch as a base material for biodegradable packaging. One interesting trend is the reinforcement of polysaccharide-based films with nano-sized components, such as cellulose or clay, according to the study. AGOSTO 2012 Página 4

To improve lignin antioxidant activity, we employed supercritical antisolvent (SAS) method for preparation of nanoscale lignin (0.144 ± 0.03 μm) using acetone as a solvent and supercritical carbon dioxide as an antisolvent. Organic nitrogen uptake by arbuscular mycorrhizal fungi in a boreal forest Publicada en ScienceDirect_NanoFood, 08/22/2012. Matthew D. Whiteside, Michelle A. Digman, Enrico Gratton, Kathleen K. Treseder The breakdown of organic nitrogen in soil is a potential rate-limiting step in nitrogen cycling. Arbuscular mycorrhizal (AM) fungi are root symbionts that might improve the ability of plants to compete for organic nitrogen products against other decomposer microbes. However, AM uptake of organic nitrogen, especially in natural systems, has traditionally been difficult to test. AGOSTO 2012 Página 13
