Discovery could mean new uses for the promising nanomaterials

18-Mar-2020

Ten years after producing the first sample of the now widely studied family of nanomaterials, called MXenes, Drexel University researchers have discovered a different way to make the atom-thin material that presents a number of new opportunities for using it. The new discovery removes water from ...
