Electroconductive MXene‐Thin‐Film‐Composite Membranes for Coupled Osmotic Concentration and PFAS Mineralization

Small, EarlyView.
An electroconductive MXene‐TFC membrane integrates osmotic dewatering with anodic oxidation to concentrate and mineralize PFOA at the membrane interface. The coupled AO‐PRO configuration accelerates degradation kinetics, achieves 99% rejection and up to 93% TOC removal, and lowers specific energy demand, offering a compact route for PFAS destruction ...

Organocatalytic asymmetric fluorination of α-chloroaldehydes involving kinetic resolution

Beilstein Journal of Organic Chemistry, 2014
In a previous study it was shown that the enantioselective α-fluorination of racemic α-chloroaldehydes with a chiral organocatalyst yielded the corresponding α-chloro-α-fluoroaldehydes with high enantioselectivity.

Deoxygenative gem-difluoroolefination of carbonyl compounds with (chlorodifluoromethyl)trimethylsilane and triphenylphosphine

Beilstein Journal of Organic Chemistry, 2014
Background: 1,1-Difluoroalkenes cannot only be used as valuable precursors for organic synthesis, but also act as bioisosteres for enzyme inhibitors. Among various methods for their preparation, the carbonyl olefination with difluoromethylene phosphonium

An Intramolecular Frustrated Lewis‐Pair Based on a Bismuth(III) Acid Site

ChemistryEurope, Volume 4, Issue 9, September 2026.
Triflate ligands were the key for the design of a frustrated Lewis pair (FLP) that utilizes a soft bismuth(III) center as the Lewis acidic site. The acceptor properties are based on empty p orbitals generated through the ionic binding of the triflate anions to the Bi center.

Investigation of Electro‐Oxidation and Ozonation for Removal of Organics in Wastewater Derived From Recycling Process for Lithium‐Ion Batteries

CleanMat, Volume 3, Issue 3, Page 170-183, September 2026.
To develop recycling processes for lithium‐ion batteries, wastewater treatment for the removal of organic compounds originating from the electrolyte was investigated using electro‐oxidation and ozonation. Based on the results, this paper proposes a process which combines these two methods to remove alcohols derived from the solvent and additives ...
