Research by Physics Professor Shows Copper Foam Could Be Highly Efficient, Durable Filter for Reusable Masks and Air Cleaners
During the COVID-19 pandemic, people have grown accustomed to wearing face masks, but many coverings are fragile and not easily disinfected. In a recent Nano Letters article, Department of Physics professor Kai Liu and his group of researchers have transformed copper nanowires into metal foams that could be used in face masks and air filtration systems, which are more durable and have the potential to effectively filter out microbes.
