Rapid Methylation of Aryl Bromides Using Air‐Stable DABCO‐Bis(Trimethylaluminum) via Nickel Metallaphotoredox Catalysis

Angewandte Chemie, EarlyView.
Herein, we report the use of bis(trimethylaluminum)‐1,4‐diazabicyclo[2.2.2]octane (DABAl‐Me3) as practical source of radicals for the introduction of valuable methyl groups to aryl bromides via a Nickel/metallaphotocatalytic cross coupling strategy.

Synergistic toxicity of some sulfonamide mixtures on Daphnia magna [PDF]

, 2018
In livestock farming, sulfonamides (SAs) are used prophylactically and simultaneously in large numbers of animals. Therefore, traces of these compounds, alone or in combination, have been repeatedly detected in the environment.

Ultrathin Polymer Electrolyte With Fast Ion Transport and Stable Interface for Practical Solid‐state Lithium Metal Batteries

Advanced Materials, EarlyView.
High‐performance ultrathin (≈7.8 µm) polycarbonate‐based electrolyte (UPCE) is fabricated, without the use of additional liquid additives. The designed UPCE delivers a high ionic conductivity (4.8 × 10−4 S cm−1) and an ultrahigh critical current density (11.5 mA cm−2) at 25 °C.
