Modification of polyester fiber by blocked isocyanate impregnating solution and its adhesion to styrene-butadiene rubber

Hecheng xiangjiao gongye
Polyester fiber was modified by blocked isocyanate impregnation system instead of resorcinol-formaldehyde-latex impregnation system. The effects of the amount of 2,2-dimethylolbutyric acid (DMBA) and the mass ratio of blocked isocyanate to butadiene ...

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes. [PDF]

Angew Chem Int Ed Engl
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

A Biosourced and Self‐Healable Polymer Electrolyte for Potassium Batteries

EcoEnergy, EarlyView.
A biosourced lignin‐filled gel polymer electrolyte combines suppressed crystallinity, high ionic conductivity, and UPy‐driven self‐healing for potassium batteries. The optimized formulation sustains long‐term cycling with 97.5% capacity retention after 1000 cycles and preserves electrochemical operation after intentional membrane damage.
