Tunable Preparation of β‐Substituted Alkenoate Esters via Radical Alkenylation of C(sp3)–H Bonds with Allenoates

Advanced Synthesis &Catalysis, EarlyView.
Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Zero‐Power, Optical Toxic Gas and Vapor Sensors Utilizing Printed Nematic Liquid Crystal Patterns on Selectively Reactive Substrates

Advanced Sensor Research, EarlyView.
Fast response, zero‐power, text or image sensors utilizing light transmission or reflection, and no unfavorable color change judgments, are fabricated using printed nematic liquid crystals patterned on reactive alignment layers, permit ppt‐ to ppb‐level sensitivity, and were field‐tested with active firefighters.

Field Trials of Low‐Cost Bi‐TiO2‐P25 Solar Photo Catalyst for Water Treatment

Advanced Sustainable Systems, EarlyView.
Journey of a low‐cost and easy to synthesize catalyst from development to validation in laboratory, followed by testing for its ability to reduce total coliform and E. Coli in the real‐world water using solar light in rural India. Abstract A low‐cost, easy to make Bi‐TiO2‐P25 composite is synthesized via a reverse micelle sol‐gel route and is tested ...
