Gelled Electrolyte Containing Phosphonium Ionic Liquids for Lithium-Ion Batteries
Nanomaterials, 2018 In this work, new gelled electrolytes were prepared based on a mixture containing phosphonium ionic liquid (IL) composed of trihexyl(tetradecyl)phosphonium cation combined with bis(trifluoromethane)sulfonimide [TFSI] counter anions and lithium salt ...

The effect of lead on dermal exposure of plasticizers in toys and associated risk assessment
Emerging ContaminantsNumerous studies reported risk assessment of human exposure to plasticizers in toys through dermal pathways, however, dermal bioaccessibility and percutaneous penetration of plasticizers under effects of lead had been seldom studied. In the present study,

Universal Reagent for Mild and Stereospecific Nucleophilic Substitution of Alcohols with Amines
Angewandte Chemie, Volume 137, Issue 13, March 24, 2025.A user‐friendly, shelf‐stable protonated betaine reagent (BEHT triflate), derived from Mitsunobu reagents, has been developed to enable the direct displacement of alcohols using primary and secondary amines as nucleophiles. The reaction with chiral, non‐racemic secondary alcohols proceeds with inversion of configuration, allowing for one‐step formation

Na2Fe3(SO4)4: A Zero‐Strain Sustainable Positive Electrode Material for Na‐Ion Batteries
Angewandte Chemie, Volume 137, Issue 44, October 27, 2025.A new sustainable zero‐strain Na2Fe3(SO4)4 (NFS) positive electrode material is obtained by only ball‐milling from cheap and available Na2SO4 and FeSO4. Iron coordination polyhedra include the Fe2O11 dimer of distorted octahedra (active during cycling) and FeO5 trigonal bipyramid, similar to that in the relative Pbca‐Na2Mn3(SO4)4 (NMS).
