This invention is a novel class of biodegradable hydrogels composed of hydrophobic biodegradable polymers [e.g., polylactide (PLA)] and hydrophilic natural polymers (e.g., dextran) that are chemically cross linked using UV photopolymerization to form an interpenetrating polymer network structure (IP.....

Dr. Cwiertny and his lab at the University of Iowa have invented a reactive filter consisting of immobilized carbon nanotubes (CNTs). In contrast to other forms of CNTs, the immobilized CNTs enhances disinfection and oxidation of pollutants in wastewater treatment systems when used in conjunction w.....
