In this work, zinc chromite (ZnCr2O4) nanostructures have been synthesized through co-precipitation method. The effect of various parameters such as alkaline agent, pH value and capping agent type was investigated on purity, particle size and morphology
(Sb2O3/Sb2O5)-doped SnO2-Co3O4-Cr2O3 varistors: The Sb2O4 in-situ formation and its influence over the electrical and microstructural properties The present study aimed to systematically study the transitions and consequential effects of antimony oxide (Sb2O3 or Sb2O5) additions over the...
Paramagnetic layered semiconductor NbS 2 doped with some transition metals can transform into ferromagnetic material. That is why such materials are promising candidates for spintronic devices. It is found that only at certain concentrations of a doping metal T crystallographic ordering is possible, which...
