Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

Advanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Zero Thermal Expansion and Local Structure in KxMnxFe2‐xMo3O12‐Based Materials

Advanced Science, EarlyView.
Local structure engineering via ion insertion drives local structural transformation from low‐symmetry P21/a to high‐symmetry R‐3c, enhancing structural flexibility and realizing a transition from positive thermal expansion to wide‐temperature‐range zero thermal expansion in KxMnxFe2‐xMo3O12‐based materials.

The potential of fluorescent light tube powder as a sustainable partial cement replacement for mortar

Results in Materials
Fluorescent light tubes are an economical source of light. However, when they cease to emit light, they become waste tubes. These waste tubes can easily break into small particles that are non-degradable, posing significant waste management challenges ...

Enhancing Li‐S Battery Performance Through Low‐Concentration Electrolytes with Organic Se/Te Co‐Additives to Address Solubility and Kinetic Challenges

Advanced Science, EarlyView.
This work presents a low‐concentration electrolyte enabled by hybrid organic Se/Te additives (DPDSe/DPDTe) that restructures solvation, boosts polysulfide dissolution, and provides dual‐site synergistic catalysis, delivering high capacity and stable cycling in Li–S coin and pouch cells, supporting high‐energy, high‐power operation.

Unusual Thermally Induced Blueshift and Emission Amplification of Mn2+ Ions Enable Filter‐Free Luminescent Thermal Imaging

Advanced Science, EarlyView.
ABSTRACT The shift from point‐based thermal sensing to filter‐free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spectral regions matching the sensitivity profiles of the red, green and blue (RGB) channels of a digital camera.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference
