Antiviral Coatings During the COVID-19 pandemic, robust and effective antimicrobial antiviral fabrics have been required. In article 2104298, Michael D. Dickey, Vi Khanh Truong, Tae-il Kim, co-workers propose an easy-to-control straightforward method to coat gallium liquid metal (LM) particles on a wide range of facilitate deposition copper alloy (LMCu) particles. This coating can offer adhesio...
