Chemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.In CH2X2 (X=Cl, Br, and I) molecules, the magnitude of σ‐hole on the X atom decreases from CH2I2 to CH2Cl2 . Three different types of interactions i. e., C−X⋅⋅⋅O halogen bond, and C−H⋅⋅⋅O and O−H⋅⋅⋅X hydrogen bond, are possible in [CH3OH−CH2X2] complexes.

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries
Batteries &Supercaps, Volume 8, Issue 3, March 2025.This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...

Batteries &Supercaps, EarlyView.This study demonstrates that the cyclic stability of all‐solid‐state fluoride ion batteries can be improved substitution of carbon by conductive oxide nanoparticles or the application of high stack pressure. Both methods avoid carbon fluorination as a parasitic side reaction, increasing coulombic efficiency and enabling high cyclic stability at high ...

Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.
