20090111897 - Reversible biogel for manipulation and separation of single-walled carbon nanotubes: The invention provides the use of novel, binary guanosine gels for simple, rapid and nondestructive solubilization of individual single walled carbon nanotubes (SWNTs) at high concentrations. The gels exhibit selectivity between metallic and semiconducting SWNTs and, further, among SWNTs with different chiralities.... Agent: Elmore Patent Law Group, PC

20090105354 - Dispersion of zirconium dioxide and zirconium mixed oxide: Dispersion of zirconium dioxide having a solids content of from 30 to 75 wt. %, based on the total amount of the dispersion, and a median value of the particle size distribution in the dispersion of less than 200 nm, obtainable by predispersing a zirconium dioxide powder and/or a zirconium... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.C.

20090105355 - Flocculant for separating and flocculating oil and water: A flocculant for separating and flocculating oily components and water components is provided so that no sludge is produced when the oily components and the water components contained in the emulsion having a high COD value; and the throughput of the active sludge is not decreased in the secondary treatment... Agent: Hedman & Costigan P.C.

20090093553 - Method for the production of suspensions of nanoparticulate solids: The invention relates to a process for preparing suspensions of nanoparticulate solids, wherein the solids present in the suspension are present in the form of nanoparticulate primary particles or very small aggregates.... Agent: Connolly Bove Lodge & Hutz LLP

20090093554 - Highly dispersible carbon nanospheres in an organic solvent and methods for making same: The particle sizes of agglomerates of carbon nanospheres are reduced by dispersing the carbon nanospheres in an organic solvent. The carbon nanospheres are multi-walled, hollow, graphitic structures with an average diameter in a range from about 10 nm to about 200 nm, more preferably about 20 nm to about 100...
