Hydrostatic pressure-induced reversible phase transformation in iron oxide nanoparticles.

We report hydrostatic pressure-induced reversible phase transformation in maghemite γ-FeO nanoparticles (cubic → tetragonal → cubic) using an diamond anvil cell (DAC) technique. Thermal arc plasma-synthesized nanoparticles, particularly in a He gas medium, exhibit the reversible phase transformation under pressure ranging from 0 to 2.58 GPa.

High-Temperature Dielectric Relaxation and Electric Conduction Mechanisms in a LaCoO-Modified NaBiTiO System.

This research study examines the high-temperature dielectric relaxation and electric conduction mechanisms in ()LaCoO-(1 - )NaBiTiO samples, where is 0.05, 0.10, and 0.

Spin and valence variation in cobalt doped barium strontium titanate ceramics.

In the present decade, owing to half-metallic ferromagnetism, controlled 3d transition metal-doping based defect engineering in oxide perovskites attracts considerable attention in the pursuit of spintronics. We aim to investigate the electronic structure of Co-doped barium strontium titanate (BaSrCoTiO where = 0, 0.1, 0.

Orbital hybridization-induced band offset phenomena in NiCdO thin films.

Herein, we present the cationic impurity-assisted band offset phenomena in NixCd1-xO (x = 0, 0.02, 0.05, 0.

High temperature-mediated rocksalt to wurtzite phase transformation in cadmium oxide nanosheets and its theoretical evidence.

Herein, a high temperature-induced phase transformation (PT) in chemically grown CdO thin films is demonstrated, and its corresponding electronic origin further investigated by density functional theory. In particular, the cubic rocksalt to hexagonal wurtzite PT in the CdO thin film annealed at 900 °C was confirmed by X-ray diffraction (XRD), which was consistent with the high-resolution transmission electron microscopy (TEM) results. Moreover, atomic force microscopy and scanning electron microscopy clearly evidenced the morphological evolution via the formation of a nanosheet network in the wurtzite-phase CdO film.

5,6-Benzoflavones as cholesterol esterase inhibitors: synthesis, biological evaluation and docking studies.

In a continued effort to develop potent cholesterol esterase (CEase) inhibitors, a series of 5,6-benzoflavone derivatives was rationally designed and synthesized by changing the position of the benzene ring attached to the flavone skeleton in previously reported 7,8-benzoflavones. All the synthesized compounds were checked for their inhibitory potential against cholesterol esterase (CEase) using a spectrophotometric assay. Among the series of forty compounds, seven derivatives (- to -) exhibited above 90 percent inhibition against CEase in an enzymatic assay.
