Cosolvent‐Enhanced Dissolution of Long‐Chain Polyamides: Toward Room‐Temperature Material Recycling of Sustainable Composites

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Long‐chain polyamides (PAs) such as bio‐derived PA11 and conventional PA12 are difficult to dissolve at room temperature, hindering facile recycling by dissolution‐based methods. This work shows that adding a weak H‐bonding cosolvent to formic acid can rapidly dissolve long‐chain PAs at room temperature by balancing H‐bonding and dispersive ...

Dielectric and Piezoelectric Properties of Nylon 9 and Nylon 11 [PDF]

open access: yesPolymer Journal, 1986
Various specimens of nylon 9 and nylon 11 were prepared, and their crystalline structures, the temperature and frequency dependences of electric properties were investigated. Dielectric constants (at 10 Hz).of various specimens were about 2.5—3 in the temperature range from −160°C to room temperature, and they began to increase near Tg and reached ...

Selective Oxidation Strategies for Cost‐Efficient Green Hydrogen Production via Hybrid Water Electrolysis

open access: yesCarbon Energy, Volume 8, Issue 6, June 2026.
Hybrid water electrolysis has emerged as a promising alternative to conventional electrolysis for sustainable hydrogen production. The economic potential of replacing water oxidation with organic substrates is assessed. For each substrate, representative electrocatalysts and mechanistic insights are reviewed to identify design principles for optimized ...
