Enhanced Responsivity, Accuracy, and Stability of Aerosol Jet Printing via Mechanical Switching Valve Assisted Internal Shuttering. [PDF]
Adv Sci (Weinh)This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

Bifunctional Aziridines from Photochemically Generated FSO2NH2 for SuFEx Diversification of Alkenes
Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.Photochemically generated FSO2NH2 serves as a safe, practical nitrene precursor for Rh‐catalyzed aziridination of alkenes, granting access to previously inaccessible fluorosulfonyl aziridines. These bifunctional electrophiles merge aziridine ring strain with SuFEx reactivity to provide a modular platform toward aliphatic sulfamoyl fluoride derivatives ...
