Cellulose Acetate Fibers With Infiltrated ZnO Nanocrystals: Activation of Antibacterial Properties Against Acne vulgaris by Oxygen Plasma Treatment

open access: yesSmall, EarlyView.
We present biodegradable cellulose acetate fibers infiltrated with ZnO nanocrystals for Acne treatment. Fibers produced by centrifugal spinning were vapor‐phase infiltrated to contain uniform ZnO nanocrystals. Oxygen plasma treatment enhanced the fibers´ wettability.

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

open access: yesSmall, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
