How can fullerenes be used as lubricants
WebCarbon can form nanoparticle structures with a variety of shapes. The fullerenes form ball shapes and tubes. Graphene consists of a sheet of carbon atoms, one atom thick. WebThey can inhibit HIV-1 and also Gram +ve bacteria. Fullerenes and their derivatives are widely used in the medical field. Fullerene, namely C60, named after Architect Richard Buckminster Fuller, was produced by vaporizing graphite in the laser beam. Fullerenes are soluble in organic solvents and not in water.
