31. They include oxides, sulfides, nitrides and phosphides. 32. Nanocrystalline vanadium nitride has been claimed to have potential for use in supercapacitors. 33. Thick polyimide can cover up the pinholes in the PECVD silicon nitride below. 34. This light uses a gallium nitride -based semiconductor for blue light emission. 35. :: : How about titanium with titanium nitride coating at the outside? 36. Additionally the barrels are nitride coated for corrosion resistance. 37. The parts are made from boron nitride powders adding boron oxide for better compressibility. 38. Combustion of boron powder in nitrogen ultrafine boron nitride used for lubricants and toners. 39. Nitrides of the 8 transition metals decompose readily.40. Heptazines could be a precursor molecule to the diamond-like beta carbon nitride .
