Among binary compounds, there is a high potential for discovery of novel members (polymorphic phases or compounds) of the nitrides of transition metals group due to a pronounced dependence of the oxidation state of the metals (M) on pressure. The pow

Sol−gel processing via the modified nonalkoxide route resulted in the formation of nanocrystals of the corundum-type In2O3 polymorph, which revealed characteristic rhombohedra with a morphology very close to cubes. Because the cubic bixbyite-type I
