Photogenerated fluphenazine radical cations for antiviral functionalization of polypropylene masks
Polymer International, EarlyView.Fluphenazine impregnated into nonwoven polypropylene masks is photoexcited to a radical cation, which inactivates viruses on the polymer surface without causing damage to the masks. Abstract The incorporation of photoactive molecules into polymeric substrates offers a compelling route to introduce advanced functionality while preserving the host ...

Animal Conservation, EarlyView.The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).
