Novel Nanostructures for Solid State Alcohol Breath Analyzers

Tricoli A., Righettoni M., Pratsinis S.E., Swiss Federal Institute of Technology, CH

Solid state alcohol breath analyzers are commonly used by the law enforcement authorities, due to high sensitivity toward ethanol, their portability and fair response and recovery times. Common materials for the synthesis of the sensitive [...]

Novel Flame-Gradient Method for Synthesis of Metal Oxide Nanomaterials

Merchan-Merchan W., Saveliev A.V., Desai M., The University of Oklahoma, US

Various transition metal oxide nanostructures are synthesized using a novel probe-flame gradient method. An opposed flow flame of methane and oxygen enriched air provides a hightemperature reacting environment forming various structures directly on the surface [...]

NanoZeolites – porous nanomaterials for cleantech, encapsulation and triggered release applications

Daniell W., Sauer J., Kohl A., NanoScape AG, DE

Recent advances in hydrothermal synthesis techniques and procedures to modify the surfaces of the particles have led to the development of a new class of material – the NanoZeolites. The availability of porous, nanocrystalline materials [...]

Nanoscaled Mg(OH)2 Used as Flame Retardant Additive

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

Headwaters Technology Innovation (HTI) has applied aqueous colloidal chemistry with great success in the development of “bottom-up” nanomaterials and nanotechnologies. One such material is a nano-scaled magnesium hydroxide, NxCat® Mg(OH)2, which is primarily used as [...]

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 [...]
