Copper/PVA films showed strong visible-light antiviral activity against MHV-3. Films with copper microparticles reduced viral load by 43% under illumination, compared with minimal reduction in the dark.

HPLC-HRMS with chemometrics showed clear metabolomic changes in herbicide-treated rice, including reduced sugars, lower flavonoids, and disrupted phenylpropanoid pathways.

Pixel-based GC×GC-TOFMS preprocessing enables rapid chemometric comparison of Brazilian pre-salt oils, revealing subtle light-hydrocarbon patterns and distinguishing Barra Velha from Itapema.
