Gadolinium aluminate perovskite (GdAlO3) was studied at high pressures of up to 23 GPa in a diamond anvil cell (DAC) using monochromatic synchrotron X-ray powder diffraction. Evidence pressure-induced phase transformation from orthorhombic (Pbnm) rhombohedral (R3¯c) structure observed 21 and further proved by DFT calculations. Before transition, the volumetric ratio polyhedron A B (i.e., VA/VB ...

In this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. For CaSnO3 preparation ammonia was used as precipitation agent. The effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. By changing in Ca(Sal)2 as a new precursor different morphologies were obtained. Ligand as a capp...

A direct electrosynthesis of H2O2 from either O2 or H2O is an attractive strategy to replace the energy-intensive industrial anthraquinone process. Two-electron water oxidation reaction (2e-WOR) offers several advantages over oxygen reduction such as better mass transfer due absence gas-phase reactants. However, 2e-WOR a more challenging and less studied process with only handful metal oxides e...
