N-N bond cleavage in N-nitrosoarylamines
The rupture of N-N bonds in three specific N-nitrosoarylamines (N,N'-dimethyl-N,N-dinitroso-para-phenylenediamine, Cupferron, and N-nitrosodiphenylamine) upon electrochemical oxidation in acetonitrile solution is investigated.

Simple, responsive and cost effective simultaneous quantification of Ga(III) and In(III) in environmental water samples [PDF]
The simultaneous determination of Ga(III) and In(III) in environmental water samples was described. The procedure was based on adsorptive stripping voltammetry using an in situ plated bismuth film electrode as a working electrode.

New solvothermal routes for GaN nanocrystals
GaN nanocrystals (see Figure) of hexagonal structure and varying diameters have been prepared by the reaction of hexamethyldisilazane (HMDS) with gallium cupferron or GaCl3 under solvothermal conditions.
