Evaluation of Antibacterial Activities of Zinc Oxide-Titanium Dioxide Nanocomposites Prepared by Sol-Gel Method

Chang H., Leung H., Nanyang Polytechnic, SG

Antibacterial activity of ceramic powders has attracted attention as a new technique that can substitute for conventional methods using organic agents. Ceramic powders of zinc oxide (ZnO), calcium oxide (CaO) and magnesium oxide (MgO) were [...]

Molecular approach for the synthesis of supported nanoparticles on active carbon using noble metal clusters

Willocq C., Vidick D., Hermans S., Delcorte A., Bertrand P., Dubois V., Devillers M., Université catholique de Louvain, BE

A molecular approach was envisaged for the preparation of nanoparticles supported on carbon. The support was first treated in order to build suitable anchors for organometallic compounds on the surface. Palladium clusters of various nuclearities [...]

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, [...]

Toughening mechanisms of nanoparticle-modified epoxy polymers

Mohammed R.D., Johnsen B.B., Kinloch A.J., Taylor A.C., Sprenger S., The University of Trinidad and Tobago, TT

An epoxy resin, cured with an anhydride, has been modified by the addition of silica nanoparticles. The particles were introduced via a sol-gel technique which gave a very well-dispersed phase of nanosilica particles which were [...]

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 [...]

Conductance Enhancement of Nanoparticulate Indium Tin Oxide Layers Made by Printing Technique

Gross M., Maksimenko I., Faber H., Linse N., Wellmann P.J., University Erlangen-Nuremberg, DE

To improve their conductance we applied several treatments on nanoparticulate indium tin oxide (In2O3:Sn, ITO) layers: post bake, infiltration by an ITO precursor solution with subsequent sol-gel transformation into ITO, treatment with etching agents as [...]

Process Intensification Strategies for the Synthesis of Superparamagnetic Nanoparticles and Fabrication of Nano-Hybrid

Chin S.F., Iyer K.S., Raston C.L., Saunders M., Miss, AU

Superparamagnetic magnetite (Fe3O4) nanoparticles are important for a diverse range of applications such as, magnetic resonance imaging, targeted drug delivery and magnetic separation. The most common cost effective and convenient way to synthesize Fe3O4 nanoparticles [...]

Investigations on the convective heat transfer in Ag – and Cu – ethylene glycol nanofluids

Dzido G., Chmiel-Kurowska K., Gierczycki A., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Science, PL

Common coolants as water, oil or ethylene glycol are characterized by poor thermal properties, i.e. convective heat transfer and heat conductivity coefficient. Addition of solid particles with size less than 100 nm can significantly improve [...]
