Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)

Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, EarlyView.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

Fluoro‐Functionalized Polyether Electrolytes Enabling High‐Energy‐Density Solid‐State Lithium‐Metal Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fluoro‐functionalized polyether electrolytes, which combine fluorine‐ and ether‐containing groups, achieve enhanced oxidative stability, high ionic conductivity, and superior interfacial stability. Due to their non‐flammability, remarkable flexibility, ease of processing, and design versatility, polymer‐based electrolytes containing polyethers have ...

Tuning Solvation Structures with KPF6 Additives for More Stable Lithium Metal Battery Cycling

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Introducing an optimal 0.1 m KPF6 additive into the conventional 1 m LiPF6‐EC/DEC electrolyte promoted small aggregate formation, enhanced Li+ transport, and facilitated a uniform SEI, thereby significantly improving the cycling stability of Li‖LiFePO4 cells. Uncontrolled dendrite growth and low Coulombic efficiency remain major challenges limiting the
