for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...

The cluster representation matrices have already been successfully used to enumerate close-packed vacancy clusters in all single-lattice crystals [I, 2]. Point defect clusters in double-lattice crystals may have identical geometry but are distinct due to unique atomic postions enclosing them. The method of representation matrices is extended to make it applicable to represent and enumerate ...
