Steigerung der Effizienz der Kaskadenreaktion für integrierte anodische H2O2‐Erzeugung und Ammoximierung durch lokale pH‐Regulierung

open access: yesAngewandte Chemie, Volume 137, Issue 47, November 17, 2025.
Diese Arbeit integriert die anodische H2O2‐Erzeugung mit Ammoximierung für eine effiziente Oximsynthese. Durch die Regulierung des lokalen pH‐Wertes durch Elektrolytoptimierung erreicht das System eine Elektroneneffizienz von 81 % und eine H2O2‐Nutzung von 98 % und bietet damit eine verallgemeinerbare Strategie für elektrochemisch‐chemische ...

Investigation on the Low-Temperature Transformations of Poly(furfuryl alcohol) Deposited on MCM-41 [PDF]

open access: yes, 2013
MCM-41-type mesoporous silica was used as a support for poly(furfuryl alcohol) deposition. This material was produced by precipitation–polycondensation of furfuryl alcohol (FA) in aqueous slurry of the SiO2 support followed by controlled partial ...

Biodegradable Polyesteramide Films for Pervaporative Dehydration of Isopropanol–Water

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 38, October 10 2025.
ABSTRACT Polyesteramides are biodegradable polymers possessing good mechanical properties with potential applicability in membrane separations. In this work, polymer films from ε‐caprolactam and ε‐caprolactone‐based polyesteramides were prepared at a ratio of monomer units set so that the resulting copolymer had a low crystalline phase content.

Dual Roles of Deep Eutectic Solvent in Polysulfide Redox and Catalysis for Intermediate‐Temperature Potassium‐Sulfur Batteries

open access: yesAdvanced Materials, Volume 37, Issue 39, October 2, 2025.
A dual‐functional NiS‐DES interfacial strategy enables highly reversible K2S2/K2S conversion in intermediate‐temperature K‐S batteries by balancing adsorption and activation of intermediates at the catalytic interface, achieving high capacity, long cycle life, and low‐cost energy storage. Abstract Potassium–sulfur (K‐S) batteries hold great promise for
