Towards Nanoscaled Systems: New Dispersing Technologies

Fischer L., Scheid S., Thomas C., Serendip AG, CH

The presentation will give an overview of state-of-the-art technologies and today’s possibilities as well as technical and regulatory limitations. The focus will be on the potential of a new generation of homogenizers, which allowfor the [...]

Self-Assembly of Polymers and NanoParticles in Personal Care Products

Berg M.C., Suddaby N.A., Soane D., Soane Labs, US

Soane Labs develops and applies nanotechnology and advanced polymer chemistry to the personal care industry trough novel colorants and high-affinity polymers. By controlling the spontaneous self-assembly of polymers and nanoparticles at interfaces, the color, look, [...]

Structure-property relationships in Pd/Polycarbonate based chemical sensors

Atre S.V., Valmikanathan O.P., Meka D.B., Prasad S., Oregon Nanoscience & Microtechnologies Institute, US

The effects of nanparticle surface chemistry, size, concentration and distribution on the properties of Pd/polycarbonate nanocomposites was investigated. Interesting trends in electrical conductivity and thermal stability of the nanomposites were identified. These trends were used [...]

Palladium/Polymer nanocomposite based Chemiresistive SO2 Sensor

Meka D., Onbattuvelli V., Atre S., Prasad S., Portland State University, US

Here we present a highly sensitive nanocomposite based Chemiresistive SO2 sensor. The main objective of this research is focused on developing a cost effective, integrable and disposable gas sensor which detects SO2 gas molecules in [...]

New Type of High Sensitive Detection of Particles Based on DeFET

Ibrahim M.F., Elsayed F., Ghallab Y.H., Badawy W., University of Calgary, CA

This research work presents a new implementation of the CMOS electric-field sensor, titled as Differential Electric Field Sensitive Field Effect Transistor (DeFET). The DeFET is successfully used in detection of small partials and it is [...]

Nanosize Iron Oxide for CO Oxidation

Wu Z., Fransson M., Zhou B., Headwaters Technology Innovations LLC, US

Transition metal oxides are desirable alternatives to precious metals based catalysts for CO oxidation since they are less costly. Several nanosize iron oxides were prepared by using Headwaters Technology Innovation (HTI) NxCat® colloidal chemistry nanotechnology. [...]

Nanomaterials down the drain: perception and reality

Sellers K., Bergeson L.L., AMEC, US

The fate of nanoparticles in commercial products at the end of product life is not entirely clear. This uncertainty, coupled with the unknowns regarding the potential for risks to human health and the environment, could [...]

Effects-Based Risk Assessment of Emerging and Existing Nanomaterials

Chan-Remillard S., Kapustka L., Goudey S., Golder Associates Ltd. & HydroQual Laboratories Ltd., CA

Nanotechnology has been compared to the industrial revolution in its scope of applications and ability to dramatically transform new and existing technologies. Nanotechnology is a quickly emerging field where the toxicological effects on human and [...]

Disinfection of Cryptosporidium Parvum Oocysts in Water using Ultrasonic Treatment

Olvera M.E., Ilangovan K., Instituto Tecnologico y de Estudios Superiores de Monterrey, MX

Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of [...]

Photocatalytic Activity Assessment of Some Transition Metal Doped

Popa M., Baia L., Baia M., Ghica C., Cosoveanu V., Baia L., Baia M., Danciu V., Babes-Bolyai University, RO

Titania based aerogels are nanoscopic pore-solid architectures with high surface area and a continuous mesoporous network fashioned from interconnected nano-quasicrystallites building blocks that make them attractive for various (photo)catalysis based applications [1]. Besides the role [...]
