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

open access: yesThe 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

open access: yesChemSusChem, 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)

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

open access: yesENERGY &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

open access: yesENERGY &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

A Sulfur Fixation Strategy via Magnesium Oxide for Constructing High‐Rate Hard Carbon Anodes in Sodium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur fixation strategy via magnesium oxide is proposed to address sulfur dissolution in hard carbon anodes for sodium‐ion batteries. This method focuses on modifying the morphological structure of the hard carbon material, leading to significantly improved electrochemical performance.

Streamlined Synthesis of Triamantane from Readily Available Starting Materials

open access: yesHelvetica Chimica Acta, EarlyView.
A practical laboratory synthesis of triamantane based on the McKervey modification of the Schleyer stabilomeric synthesis is described. A high‐yielding rearrangement of Binor‐S and a significantly facilitated Diels–Alder step allowed an operationally simple sequence that reliably delivers triamantane on a tens‐of‐grams scale.

New Thioethers From 2-Nitropentachloro-1,3-Butadiene And Sulfonyl-1,3-Butadienes And Sulfinyl-1,3-Butadienes From Tetrakis(Organylthio)-1,3-Butadienes And Tris(Organylthio)-1,3-Butadienes

open access: yes, 1994
2-Nitropentachlorobutadiene (1) gives 3a-b, 3d and 4c by the reaction with thiols in DMF containing triethylamine. 5a-b, 6c and 6d are prepared by the reaction of compound 1 with thiols in EtOH containing sodium hydroxide. 7c and 7d are formed by the reaction of compound 1 with thiols in the absence of a solvent. Poly(thio)substituted compounds (8, 10,
