Pulsed‐Laser Ablation for the Synthesis of High‐Entropy Alloy Aerogels Toward H2O2 Production and Water Decolorization

Angewandte Chemie International Edition, EarlyView.
This work establishes a universal strategy for fabricating compositionally complex solid solution alloy aerogels via pulsed‐laser ablation and the sol‐gel process. The electrocatalytic capabilities of these aerogels are subsequently evaluated for H2O2 electrosynthesis and water treatment applications.

Uranium Isotope Fractionation During Coprecipitation with Aragonite and Calcite

, 2015
: Natural variations in 238U/235U of marine carbonates might provide a useful way of constraining redox conditions of ancient environments. In order to evaluate the reliability of this proxy, we conducted aragonite and calcite coprecipitation experiments

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.
