Effect of Sonication on Mechanical Properties of Polymers and Nanocomposites

Sha X., Beyle A., Ibeh C.C., Pittsburg State University, US

This study investigates the influence of sonication on the viscosity and mechanical properties of polymeric nanocomposites. Parameters of study are percentage level of catalyst, temperature level, neat polymer (vinyl ester), nanoparticle [nanoclay] infused polymer (nanocomposite) [...]

Metal-polymer hybrid material: A unique coordination for carbon-carbon coupling reactions

Islam R.U., Witcomb M.J., Mallick K., Mintek, ZA

A method for making poly-aminophenol based hybrid material by in-situ polymerization of aminophenol using palladium acetate as the oxidant is described. The oxidative polymerization of aminophenol leads to the formation of poly-aminophenol, while the reduction [...]

Nanoparticle synthesis using polyelectrolyte nanoreactors

Anderson D.J., Dinglasan J., Goh J.B., Goh M.C., Veletanlic E., Goh J.B., Goh M.C., Vive Nano, CA

We report a facile method to synthesize a wide range of nanoparticles via polyelectrolyte nanoreactors. The nanoreactors are formed through ion-induced collapse of highly extended, high molecular weight anionic polyelectrolytes using metal salts. The formation [...]

Spray-coating deposition for large area organic thin-film devices

Abdellah A., Baierl D., Fabel B., Lugli P., Scarpa G., Technische Universitaet Muenchen, DE

Organic electronic devices based on solution-processable polymers are among the most promising applications of organic semiconductors. Low-cost fabrication by means of simple coating and printing techniques is surely one of their greatest advantages. We report [...]

Nanopatterned Organic Materials for Photovoltaic Devices

Williams S.S., Hampton M.J., Retterer S.T., Templeton J.L., Samulski E.T., DeSimone J.M., University of North Carolina at Chapel Hill, US

In order to further increase the efficiency of current state-of-the-art photovoltaic devices, the interfacial architecture must be controlled at the nanoscale such that the D/A blend results in an ideal morphology for maximizing charge collection [...]

Conformational analysis of alternating copolymers and their association into nanoarchitectures

Chan A.S.W., Groves M., Malardier-Jugroot C., Royal Military College of Canada, CA

Our research focuses on the characterization of the association and the properties in aqueous solution of nano-structures, particularly on nanotubes composed of amphiphilic alternating copolymers. These copolymers constitute a pH sensitive hydrophilic group (maleic anhydride) [...]

The SURVISMETER – a Green Technology in Service

Singh M., Bhanumati S., Shukla A., Shukla S.S., Shukla A., Shukla S.S., University of Delhi, IN

Viscosity is a measure of stickiness and the reverse is fluidity. It is a valuable data for all liquids in the oil, lubricant, paint, polish, food, beverage, cosmetic, biosolvents, drugs and pharma, polymer, nanomaterials, and [...]

Synthesis of thermal interface material with high thermal conductivity for high efficacy of LED

Han C.J., Han J.-I., Yu S.H., Hong S-J, Kim Y-S, Han C.J., Han J.-I., Korean Electronics Technology Institute, KR

Thermal dissipation problem for LED is critical for high efficacy and reliability. Inorganic filled grease type thermal interface material (TIM) has widespread use for heat management of LED. Conventional TIM materials, however, has relative low [...]

Enhanced Biodegradation of 2,3,4,5,6-pentachlorocyclohexan-1-ol — a b-HCH Metabolite — in the Presence of a and g-HCH Isomers by Pseudomonas aeruginosa ITRC-5

Singh A., Kumar A., Misra K., Rice University, US

Chlorinated insecticide hexachlorocyclohexane (HCH), which is still used in many countries in agriculture and forestry, leads to environmental problems. HCH consists of a mixture of four isomers: a-, b-, g-, and d. Efforts have been [...]

Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water

Singh A., Sar P., Bennett G., Rice University, US

The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]
