This study explores the properties of NaMgMn2O4 spinel oxide, focusing on its structural, magnetic, electronic, optical, and thermoelectric characteristics
CdS single crystals of various stoichiometric ratios have been grown in vacuum sealed ampoules using the vertical pulling method. Stoichiometry and physical properties of the crystals were found to be strongly dependent on the pre-treatment of the charge. Optical transmission, electrical and microhardness...
Perovskite Strain Optical properties First-principles analysis Spin-orbital coupling effect And optoelectronic device 1. Introduction Solar power is an essential eco-friendly and sustainable energy source. Solar photovoltaic technology provides a remarkable alternative to conventional energy sources [1]. Photov...
method45. VASP was used to optimize the crystal structures and to calculate the mechanical properties. The Perdew-Burke-Ernzerhof (PBE) generalized-gradient-approximation (GGA)46was used for the exchange and correlation potential in solving the Kohn-Sham equation with an energy cut-off of 500 eV...
Question: What are the physical properties of carbonate minerals? Recrystallization: Recrystallization is when a substance is dissolved so that it can be purified in a hot liquid. When the solvent cools down, the solution is saturated with the solute that crystalizes, or forms a solid again. Car...
Why are ionic bonds stronger than covalent? How can one tell what bonds have been broken and what bonds have been formed from a chemical reaction? What are the differences between covalent bonds and ionic bonds? What determines the chemical properties of an atom?
