The present invention provides anodes comprising an electrically conductive substrate, comprising at least one non-uniform surface; and a random network of silicon nanowires (Si NWs) chemically grown on said at least one non-uniform surface of the substrate, wherein the Si NWs have at least about 30% amorphous morphology, and methods of manufacturing of the anodes. Further provided are lithium ion batteries comprising said anodes.

High-capacity silicon nanowire based anode for lithium-ion batteries

A method of fabricating a nanostructure, which comprises forming an elongated tubular nanostructure, and generating conditions for said tubular nanostructure to unwrap.

Method of fabricating a nanoribbon and applications thereof

Provided is a method for preparing letrozole, which includes reacting an activated bis-(4-cyanophenyl)-methane with a triazole to produce letrozole, and, optionally, purifying the letrozole. Also provided are highly pure letrozole, and a method of purifying letrozole, which method includes precipitating letrozole, e.g., by selective precipitation from a reaction mixture and/or by subjecting the letrozole to one or more crystallizations.

Letrozole production process

A novel process for preparing highly pure cilostazol, effected by reacting 6-hydroxy-3,4-dihydroquinolinone and 5-(4-chlorobutyl)-1-cyclohexyl-1H-tetrazole in the presence of a hydrated inorganic base, is disclosed. Further disclosed is highly pure cilostazol, and particularly highly pure cilostazol that is substantially free of 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)-butoxy]-1-[4-(1-cyclohexyl-1H-tetrazol-5-yl)-butyl ]-3,4-dihydro-1H-quinolin-2-one.

Highly pure cilostazol and an improved process for obtaining same
