Commercial Applications of Oleophobic and Superoleophobic Membranes

Ratnasinghe L., Lanza E., Cytonix, LLC, US

We will present data on the performance of oleophobic and superoleophobic surfaces for a variety of commercial membrane and filter applications. It is well known that oleophobic surfaces create oil resistant, anti-fingerprint surfaces that are [...]

NanoZeolites – small particles, small pore, big impact! Porous nanoparticles for environmental applications

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

NanoScape has developed hydrothermal synthesis techniques which allow nanocrystalline, porous aluminosilicates (NanoZeolites) to be manufactured, currently on a 100kg p.a. scale. A range of NanoZeolites are available with pore sizes ranging from 3A to 100A. [...]

New nanostructured cellulose materials

Vismara E., Gastaldi G., Melone L., Cosentino C., Torri G., Politecnico di Milano, IT

Optimized synthesis of new cellulose-GMA materials via radical and physical chemical activation, their chemical composition determination and derivatization quantification. Structural solid state NMR and IR ATR characterizations. Derivative screenings for possible use in filtration of [...]

Experimental evaluation of individual protection devices against nanoaerosols:

Golanski L., Rouillon F., Guiot A., Bernard S., Tardif F., CEA, FR

Analysts have estimated that the worldwide market for nanoparticles will be about 340 billion Euro in 2011 which would rank it alongside the automobile and microelectronic industries. However, potential impact of these new materials on [...]
