Two researchers at Penn State University 's Department of Material Science and Engineering have invented a novel inhibitor that has a high efficiency to prevent copper corrosion in acidic solutions and in acidified neutral solutions and atmospheres. The inventors have demonstrated that this invention significantly decreases the corrosion rate of copper in sulfuric acid and also in neutral saltwater in comparison to BTA, which is presently the best inhibitor available on the market. Low temperature formation permits the formation of calcium deficient HAp coatings.
Calcium deficiency is critical in providing a resorbable coating.
Incorporation of fluoride where resorption is not desirable. The formation of adherent coatings of HAp on metal, ceramic, or polymeric substrates. The correct treatment of electron correlation in molecules needs a great deal of computing power because the size of the problem grows exponentially with the number of electrons in the problem. A large number of problems cannot be solved because of this difficulty. One problem with commercial possibilities is searching new catalyses for chemical and biological systems by computer simulations.
