Exploring the Catalytic Activity of Ge(II) and Sn(II) Cationic Crown Ether Complexes: Hydrosilylation

Chemistry – A European Journal, EarlyView.
Easily synthesized [Ge([12]crown‐4)2][OTf]2 catalyzes the hydrosilylation of aldehydes to give reductively coupled ethers via a carbonyl‐activated reaction pathway. The mechanism proceeds through two distinct steps: hydrosilylation followed by etherification. The open coordination face of the active cationic Ge(II) catalyst facilitates the coordination

Amino Acid Modified Polymer Mesh for Removal of the Heavy Metal Ions Pb2+, Hg2+, Cu2+, and Ni2+ From Aqueous Solutions

Chemie Ingenieur Technik, EarlyView.
Adsorbents for cations of copper, lead, mercury, and nickel are obtained via grafting polymer mesh with an acrylic acid copolymer and subsequent functionalization with an amino acid. A distinct influence of the type of amino acid on the adsorption occurs.

Water‐based drilling fluids formulated with mature fine tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Mature fine tailings (MFT) are persistent, highly stable colloidal suspensions generated as byproducts of bitumen extraction from oil sands. Given their environmental risks, identifying viable applications for MFT could reduce their accumulation while offsetting natural resource use.

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.
