This entrepreneur claims his graphene-silver-coated masks kill coronavirus

Vikas Bardiya's firm Nanomatrix has, in a span of about a year, developed a dealer network in several large Indian cities and is exporting to the US, UAE and Thailand

It's an allotrope of carbon that has become a buzzword in industry for its tensile strength, which is about 100x that of steel of the same thickness. Scientists say the material, graphene, isn't something new and has, in fact, been used unknowingly for centuries in pencils and other applications of graphite. But its rediscovery in 2004 got scientists at the University of Manchester the Physics Nobel in 2010. Graphene today has applications in semiconductors, electronics, solar cells, smart phones, filtration, construction and even bio-engineering and cleaning up oil spills.
