Extraction rates of zinc with ammonium chloride salts of Amberlite LA-2 in a horizontal rectangular channel.

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1989
Extraction rates of zinc with ammonium chloride salts of Amberlite LA-2 in hexane were measured in a horizontal rectangular channel. The experimental results were analyzed by considering the processes of diffusion in both solutions, adsorption and desorption to/from the interface and reactions at the interface for the species related as following steps;

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Differential effects of lipid composition on the thermal and functional properties of membrane associated CYP2J2

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract CYP2J2 is a membrane‐bound cytochrome P450 that is expressed in cardiomyocytes, where it is known to metabolize arachidonic acid into cardioprotective epoxyeicosatrienoic acids (EETs). It consists of transmembrane domains embedded in the hydrophobic segments of the cell membrane and surrounded by various lipids.

N‐Glycosyl Triazoline Glycomimetics via Huisgen Cycloaddition With an Electron‐Deficient Alkene and BF3‐Catalysed Triazoline Fragmentation to Aziridines

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 22, 9 June 2026.
Glycomimetics with triazoline and aziridine groups were synthesised via diastereoselective Huisgen cycloaddition from glycosyl azides. Density functional theory was applied to define the mechanism for BF3 promoted aziridine formation. Triazoline and aziridine derivatives were synthesised by diastereo‐ and regioselective Huisgen cycloaddition of 2,3,4,6‐
