Graphene’s Great Water-Filtration Potential Unveiled By New Research

The great potential that graphene has shown with regard to electronics and energy technologies is well known, but there’s quite a bit more to graphene than ‘just’ that…. In particular, the material possesses a number of strange qualities with regard to its interactions with water — qualities that are now … [continued]

Plasma-treated, Carbon-nanotube Filters For Water Purification In Developing Countries

Plasma-treated carbon nanotubes can function very effectively as an inexpensive means of purifying water in developing countries, according to new research from the Singapore University of Technology and Design. Water purification membranes enhanced with the plasma-treated carbon nanotubes are ‘perfectly’ structured for the removal of contaminants and brine from water, … [continued]
