Understanding Relative Reactivity-Governed Kinetics and Network Formation in Thiol-Yne and Other Competitive Consecutive Polymerizations

Abstract Thiol-yne polymerizations couple two sequential additions of thiol: first, to an alkyne and subsequently, to a vinyl sulfide, making the polymerization and the resulting polymer structure dependent on the relative reactivity. Herein, kinetic, analytical, and random-graph...

Nitric oxide–regulated temporally staged milk exosome hydrogel for the treatment of skin photoaging

Ultraviolet (UV)–induced skin photodamage can lead to sunburn, photoaging, and, in severe cases, precancerous lesions or malignant skin tumors. Cutaneous responses to UV injury exhibit pronounced circadian rhythmicity; however, current strategies focusing solely on physical UV sh...
