By turning chitosan into beads and impregnating them with nanoparticles of titanium dioxide and aluminum oxide, scientists developed a technique that removes both arsenite and arsenate with the same efficacy as the nanopowders, but without the post-treatment filtration requirements. Inorganic arsenic, which can contaminate water supplies via runoff from industrialContinue Reading

By using spray-painted layers, each representing the components in a traditional battery, researchers at Rice University have developed lithium-ion batteries with consistent capacities that can be painted on almost any surface. Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface. The rechargeableContinue Reading

Using computer simulations, engineers at MIT have developed a new graphene-based desalination system that uses sheets of graphene with precisely sized holes, improving permeability and working hundreds of times faster than current techniques at the same pressure. The availability of fresh water is dwindling in many parts of the world, a problem thatContinue Reading
