Solid Polymer Electrolyte with Compatible Cathode‐Electrolyte Interfacial Design Enabling Lithium Metal Batteries Operation at 4.8 V with Long Cycle Life

Advanced Materials, EarlyView.
This study introduce a novel approach to enhancing cathode‐SPE compatibility by utilizing the same poly(ionic liquid) (PolyIL)‐based material in both the SPE and the cathode binder. A modified biomass‐based PolyIL substrate, enriched with highly negatively charged C═O and ─OH groups, is incorporated into the SPE to improve Li+ migration and strengthen ...

Pairing N‐Vacancy and Adjacent Ni‐Sites in the Local Microenvironment to Regulate the Urea Oxidation Reaction Pathway With Enhanced Kinetics

Advanced Materials, EarlyView.
In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Mathematical modelling of flow and adsorption in a gas chromatograph [PDF]

arXiv
In this paper, a mathematical model is developed to describe the evolution of the concentration of compounds through a gas chromatography column. The model couples mass balances and kinetic equations for all components. Both single and multiple-component cases are considered with constant or variable velocity. Non-dimensionalisation indicates the small

Hyocholic acid as internal standard for quantitation of human fecal bile acids

Journal of Lipid Research, 1973
After hyocholate is added to a fecal homogenate, the bile acids are extracted, purified by thin-layer chromatography, and quantitated by gas–liquid chromatography as methyl ester trifluoroacetates on QF-1 columns.
