Highly Efficient Transfer Hydrogenation of Alkenes With Ammonia Borane Mediated by a Simple Ni(II) Catalyst System

European Journal of Inorganic Chemistry, EarlyView.
Simple Ni(II) precatalysts and ammonia borane (AB) enable rapid, selective transfer hydrogenation of alkenes with turnover numbers up to 3960. AB activates the precatalyst through reduction to catalytically competent low‐valent nickel species and simultaneously provides H2 for hydrogenation. Transient hydride‐like species may be observed under selected

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

European Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

Molecular‐Grafting‐Induced Anion Immobilization in Polymer Electrolytes for High‐Transference‐Number and Dendrite‐Free Solid‐State Lithium Batteries

Electron, EarlyView.
By grafting lithium phenylsulfonate onto a PVDF backbone, we create a solid electrolyte that immobilizes anions and enhances Li+ transport. This results in a high Li+ transference number (0.67) and uniform ion flux, enabling stable, dendrite‐free cycling in lithium metal batteries.

Modelling the process of perchloroethylene removal from water using Zero Valent Iron-Permeable Reactive Barrier

سلامت و محیط, 2015
Background and objectives: Perchloroethylene (PCE) is categorized as contaminant of concern because of its adverse health effects and persistence in drinking water resources. Permeable reactive barrier with zero valent iron (ZVI-PRB) is a passive zone in

Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

FlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...

Water‐driven dispersible fiber electrode arrays for position‐dependent intracardiac electrophysiological recording

FlexMat, EarlyView.
Abstract Intracardiac electrophysiological recording plays an essential role in identifying abnormal cardiac electrical activity and guiding arrhythmia diagnosis and treatment planning. A key challenge for minimally invasive intracardiac electrodes is to combine reliable transvascular delivery with stable and compliant endocardial contact.

A Numerical Model (SEAM3D) to Assess the Biotransformation of Chlorinated Ethenes at a TCE/BTEX Contaminated Site

, 2002
Numerical models (GMS MODFLOW, SEAM3D, and SEAM3D Interface) were applied to simulate groundwater flow, petroleum hydrocarbon compound (PHC) transport and biodegradation, and the transport and biotransformation of chlorinated ethenes at Site FT-002 ...
