Abstract

In this study, novel nano crystalline composite strings made from mixed nickel-tungsten oxides (NiWO4-WO3-WO2.9) have been fabricated. The NiWO4-WO3 fibers produced by the electrospinning method were post treated in an argon atmosphere at 800°C which yielded NiWO4-WO3-WO2.9 nanocrystals attached tog...
