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 ...

Metalloporphyrin‐Based Cathode for Rechargeable Magnesium‐Ion Batteries: Copper Leaching and Interphase Formation

ChemSusChem, EarlyView.
The initial cycling of [5,15‐bis(ethynyl)‐10,20‐diphenylporphinato]copper(II) electrodes in rechargeable Mg‐ion batteries is studied using electrochemical, spectroscopic, microscopic, and spectrometric methods such as total reflection X‐ray fluorescence spectrometry and time‐of‐flight secondary ion mass spectrometry .

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Recent Advances on Self‐Powered Metal Halide Perovskite Photodetectors

EcoEnergy, EarlyView.
This review outlines that metal halide perovskites, with high absorption coefficient and carrier mobility, enable self‐powered photodetectors. These devices operate without external power, with improvements via structural optimization, film engineering, and defect passivation, showing promise in smart sensors and Internet of Things applications ...
