Light as a feather – technology to tackle Covid-19

March 25, 2021

Professor Kai Liu of the Georgetown Physics Department, has created a material that could be the basis of the next generation of ultra-effective face masks and air filters. Having begun work using metallic foams for hydrogen storage and to control air pollution, Kai pivoted last year to apply the nanotechnology to the COVID-19 crisis, exploiting the material’s efficiency, reusability, and recyclability to create low-cost face masks that have the potential to out-perform the N95 masks currently considered the gold standard in preventing transmission of the virus. The results are reported in Nano Letters.
