Nitrocellulose-Stabilized Silver Nanoparticles as Low Conversion Temperature Precursors for Inkjet-Printed Electronic Circuits

Nguyen B.T., Nguyen M.T., Gautrot J.E., Nguyen B.T., Nguyen M.T., Zhu X.X., Université de Montréal, CA

Liquid-based inkjet printing is considered as a constructive (rather than destructuve) low-cost technique for printed circuit boards fabrication. A convenient way of depositing silver films and lines using inkjet technology is to generate silver nanoparticles [...]

Dispersing Nanoparticles – The Key to Application

Pilotek S., Tabellion F., Schär S., Steingröver K., Buhler PARTEC GmbH, DE

Inorganic nanoparticles are used in many different branches: e.g. display technology, consumer goods, coatings, plastics, cosmetics, and paper industry use nanoparticles as major components or functional additives. In most applications, the particles are needed in [...]

Nanophase Separated Anionic Amphiphilic Model Polymer Conetworks Based on Methacrylic acid

Kali G., Georgiou T.K., Iván B., Patrickios C.S., Loizou E., Thomann Y., Tiller J., Hungaryan Academy of Sciences, HU

Two series of model amphiphilic polymer conetworks were synthesized by group transfer polymerization (GTP). The first one was composed of the hydrophobic methyl methacrylate (MMA) and the hydrophilic methacrylic acid (MAA), and the second one [...]

Morphology and Phase Transitions in Styrene-Butadiene-Styrene Triblock Copolymer Grafted with Polyhedral Oligomeric Silsesquioxanes

Drazkowski D.B., Lee A., Michigan State University, US

Two symmetric triblock copolymers of polystyrene-butadiene-polystyrene (SBS) with different styrene content were grafted with varying amounts of polyhedral oligomeric silsesquioxane (POSS) molecules with either isobutyl or phenyl moiety. The POSS octamers, R’R7Si8O12 were designed to [...]

Parylene Polymers for Nanotechnology Applications

Kumar R., Greiner A., Specialty Coating Systems, US

During the past several years, Parylene polymers have been considered an integral part of micro devices by many biomedical engineering researchers as devices are made of Parylene through MEMs technology. In advancing Parylenes applications further [...]

Technological prospecting on Area of Nanotechnology with emphasis in nanostructured polymers

Borschiver S., Jose Guimaraes M., Nahum e Marietta Lissker, BR

The areas of application for nanotechnology extend to practically all industrial and service sectors. Currently there exist initiatives for investment in nanotechnology in both developed countries and those in the process of development. The present [...]

New Characterisation Techniques for the Study of Nanoscale Polymeric Systems in Two- & Three-Dimensions

Stokes D.J., Reyntjens S., Jiao C., Hayles M.F., Hubert D.H.W., FEI Company, NL

Activity in the development of polymer-based materials, composites and devices is more intense than ever. At the same time, techniques and methods for their characterisation have become more powerful, giving new insights into the spatial [...]

pH-responsive self assemblies for “smart surface coatings”

Baquey G., Sakai K., Perrier S., Biggs S., Chamelic Ltd, UK

Over the last few years, adsorption of polyelectrolytes at solid/liquid interfaces has gained in popularity due to their potential applications for drug delivery, for the preparation of nanosized materials and for the fabrication of smart [...]

Vibrational spectroscopy of nanoscale needle shaped histamine

Sonois V., Faller P., Bacsa W.S., Fazouan N., Estève A., University Paul Sabatier, FR

Amino acids in aqueous solutions have low Raman signals and are difficult to detect at low concentrations. To increase Raman signals one often uses UV excitation. We find that nano-needels can be grown from droplets [...]

Controlling the Surfaces of Food: Self-Assembly of Biopolymers

Berg M.C., Mowers W.A., Silberstein S.R., Soane D., DuraFizz, LLC, US

DuraFizz develops and applies nanotechnology-inspired innovations to the food industry by controlling the spontaneous self-assembly of biopolymers at surfaces. This principle is demonstrated in several current research projects including nutrient encapsulation, edible foams, and fryer [...]
