Nickel oxide NPs are widely recognized as excellent photocatalysts due to their unique optical features such bandgap energy, retention time, strong light absorption, electron-hole recombination duration, and significant negative oxidation potential of excited electrons. NiO nanoparticles were successfully created using a combination nickel hexahydrate precursor, ethanol, distilled water. was em...

In this study, High temperature superconductor YBa2Cu3O7-x (YBCO) nanoparticle was prepared by Sol-gel technique. The sol-gel includes a homogeneous solution of Y-Ba-Cu acetate precursor and acetic acid. powder compressed hydraulic at 5 ton/cm2 needed post-reaction heat treatment 850 °C for 8 h with oxygen flow. YBCO bulk has been characterized using traditional R-T measurements, producing best...
