Summary: A BCFS perovskite hollow fiber membrane was prepared by phase inversion and sintering technique with the addition of Co2O3 to enhance mechanical strength and reduce sintering temperature. The membrane exhibits simultaneous permeation of hydrogen and oxygen, showing potential as a catalytic membrane reactor for various reactions. Simultaneous permeation enhances hydrogen and oxygen fluxes by reducing gas concentrations and promoting gas/ion exchange reactions.

Summary: Three high entropy BSCF perovskite membranes were designed and analyzed to improve oxygen permeation stability at high temperatures. The degradation mechanism was studied and a strategy to enhance stability was proposed. Coating the surfaces with Sm0.5Sr0.5CoO3-delta (SSC) improved the permeation stability and the high entropy strategy helped restrain phase transition.

Summary: SrFe0.95Mo0.05O3-delta (SFM5) perovskite hollow fiber (HF) membranes with a finger-like structure were fabricated using a phase inversion technique. The oxygen flux through SFM5 hollow fiber membrane was evaluated and reached 0.64 mu mol/cm2 *s at T = 880 degrees C, which is 5 times higher than that of a disk SFM5 membrane (0.12 mu mol/ cm2 *s). A further increase in oxygen fluxes was attained by Ag deposition on the inner surface of SFM5 hollow fiber membrane. The oxygen flux of SFM5 HF membranes is governed by surface-exchange reactions on the permeate side. The equilibrium 3 -delta -lg pO2 -T diagrams showed that doping of SF by molybdenum leads to a broadening of the cubic perovskite phase stability region.

Summary: Perovskite oxides with mixed ionic and electronic conductivity are of interest for oxygen separation membranes, but they often degrade due to segregation and reaction with sulfur-based species in natural gas. Coating these membranes with Alumina layers by atomic layer deposition can delay or prevent degradation, with a critical coating thickness of around 30 nm showing no negative effect on O-2 transport flux and good flux recovery after H2S removal. Thinner coatings provide little protection against poisoning, while thicker coatings significantly decrease O-2 permeation fluxes.

Summary: X-ray absorption spectroscopy was used to evaluate the correlations between oxygen desorption/absorption and electronic structure in SrFe0.6Mn0.4O3-delta. The research showed that the valence state of Fe ions changes and the coordination symmetry of Mn and Fe changes as temperature rises in the perovskite-type oxide. Oxygen release from the FeO6 octahedron was found to be accompanied by variations in neighboring Mn-O polyhedrons. The study suggests that optimizing the B-site elements in perovskite-type materials can enhance their oxygen storage capabilities.

Summary: The supercritical CO2-subcritical H2O system can serve as a reaction solvent for organic synthesis, promoting the conversion of organic compounds due to enhanced formation of carbonic acid and ionization of water under elevated pressures and temperatures. The biphasic nature of the system allows for extraction of less polar products from aqueous solutions. Experimental results showed higher yields and selectivity in converting glucose to HMF in this system, with potential mechanisms determined through quantum calculations.
