The A-site high-entropy perovskite oxide (La 1/6 Pr Nd Gd Sr Ba )MnO 3 with enhanced hydrogen production, phase stability, and surface oxygen exchange kinetics, offering the potential for tailoring properties in STCH application.
Repeatable tumor measurements are key to accurately assessing growth and treatment efficacy. A preliminary study that we conducted showed a novel 3D thermal imaging system (3D-TI) for measuring subcutaneous tumors in rodents significantly reduced interoperator variability across 3 vivo efficacy studies. Here further studied this reduction much larger dataset. dataset consisting of 6,532 paired 3D-TI caliper was obtained from scans 27 laboratories 289 studies, 153 operators, over 20 mouse...
Li, Na, K, Rb, and Cs have been intercalated into the two-dimensional (2D) van der Waals material WO2Cl2, with intercalation being reported for first time. The topochemical reaction of these alkali metals causes dramatic crystallographic, optical, electronic changes to WO2Cl2. During each metals, WO2Cl2 from a clear transparent insulating phase blue partially species finally lustrous bronze material. Upon intercalation, host undergoes significant systematic in interlayer spacing, as well 10...
In this work, the A-site of common SOFC cathode La 0.8 Sr 0.2 MnO 3-δ (LSM) is modified with additional lanthanide and alkali elements, resulting in composition (La 1/6 Pr Nd Gd Ba )MnO 3- δ . We show that amount oxygen released during reduction measured by thermo-gravimetric analysis significantly greater for “high entropy” perovskite oxide (HEPO) comparison 2/3 1/3 , latter having same total acceptor dopant a similar average radius. The origins enhanced will be discussed.
Recent atom interferometry (AI) experiments involving Bose–Einstein condensates (BECs) have been conducted under extreme conditions of volume and interrogation time. Numerical solution the rotating-frame Gross–Pitaevskii equation (RFGPE), which is standard mean-field theory applied to these experiments, impractical due excessive computation time memory required. We present a variational model that provides approximate solutions RFGPE for power-law potential on practical scale. This...
Compositionally complex oxides (CCOs), also referred to as high entropy oxides, have several different cations (typically 5 or more) occupying a single site. CCOs shown unique dielectric, ionic conductivity, and thermal conductivity properties, in addition promising electrochemical properties for solid oxide fuel cells (SOFCs) [1,2]. In this work, the A-site of common SOFC cathode La 0.8 Sr 0.2 MnO 3-δ (LSM) is modified with additional lanthanide alkali elements, resulting composition (La...
Solar thermochemical hydrogen (STCH) production uses concentrated sunlight to produce using reduction/oxidation of metal oxides. Typically, the oxide is heated high temperature (>1400 o C) causing it release oxygen, then cooled a lower (<1000 in steam whereby re-oxidizes, stripping oxygen from water molecules and producing hydrogen. Due improved stability, non-stoichiometric oxides that do not change phase during STCH process are typically used, even though reversible content less than...
