Addition of carbonyl fluoride to organic and inorganic nitriles
… of anhydrous acid, the presence of an alkali metal fluoride and/or an increase in reaction time. The a,a-difluoroethyl isocyanate reacted with anhydrous ethyl alcohol to form the carbamate which slowly decomposed by splitting out hydrogen fluoride. The addition reaction proceeded more rapidly, …

Synthesis and evaluation of rare-earth doped glasses and crystals for optical refrigeration
… laser-cooling efficiency in Yb3+ and Tm3+ doped fluorides. The first instance of laser-induced cooling in a Tm3+-doped crystal, BaY2F8 was reported. Cooling by 3 degrees Kelvin below ambient temperature was obtained in a single-pass pump geometry at λ = 1855 nm. Protocols were developed for …

Tailoring Fluoride/Fluorine Bond Activity for High-Energy Li and Li-ion Batteries
… Li-ion cathodes utilize lithium transition metal oxides, while MnO₂, SOCl₂, and SO₂ are representative examples for Li primary cathodes. In contrast, fluoride-based cathodes are generally less investigated, with only several instances, but all with exceedingly high theoretical energy …
