Abstract

A variety of bismuth oxides have been synthesized by hydrothermal reactions using NaBiO3·nH2O as a starting material.

Ultra-violet to visible band gap engineering of cubic halide KCaCl3 perovskite under pressure for optoelectronic applications: insights from DFT

“… 21–23 Because of their immense physical properties, such as photocatalytic, dielectric, ferroelectric, pyroelectric, piezoelectric, magnetic, superconductivity, and ionic conductivity, 24–31 perovskites are often referred to as “the department store of physical properties”. 32 The simple cubic perovskite with space group Pm 3̄ m (#221) could be oxide based (general formula ABO 3 ) 33 or halide based (general formula ABX 3 ), 34 where A and B are cations, while X is a monovalent halogen anion. 35 The first-principle calculations were successfully implemented to cubic perovskite compounds to analyze different physical properties.…”

Fe-Doped polydopamine nanoparticles with peroxidase-mimicking activity for the detection of hypoxanthine related to meat freshness

“…A high-temperature hydrothermal technique provides an efficient material synthesis method for controlling the crystal structure, crystallization form and grain purity of nanoparticles by adjusting the reaction conditions, which can quickly form crystal nucleation and accelerate crystal growth under high temperature and high pressure, effectively increasing the reaction speed and resulting in nanoparticles with high purity, uniform distribution, no agglomeration, crystalline form, and controllable properties. 35–38 Considering such excellent features, we successfully synthesized the spherical form of Fe-PDA for the colorimetric detection of hypoxanthine in various meat samples through the high-temperature hydrothermal reaction, and the surface morphology of the obtained Fe-PDA was studied by TEM (Fig. 2A).…”

Pressure-induced tuning of physical properties in high-throughput metal halide MSn2Br5 (M = K, Cs) perovskites for optoelectronic applications

“…The physical properties of a material, and hence its potential uses, are oen analyzed using both experimental and theoretical methods. [10][11][12][13] The arrangement of atoms within a material can signicantly affect its physical characteristics. Perovskite materials encompass a wide range of properties, such as conductivity, insulation, semi-conduction, and superconductivity.…”
