I NDUSTRY NEWS Clifford K. Schoff Named Winner of Tess Award WASHINGTON — Dr. Clifford K. Schoff, formerly of PPG Industries and now a private consultant, will receive the Roy W. Tess Award in Coatings for 2008. Schoff is recognized as one of the world’s leading experts in the area of coatings defects, electropaint-substrate interactions, paint flow and rheological measurements, mechanical properties, and cure of coatings. He has contributed over 40 papers, articles and chapters to coatings literature and recently published his 40th one-page “Coatings Clinic” in JCT Coatings Tech. Schoff has led ASTM Subcommittee D.01.24 on Physical Properties of Liquid Paints for over 20 years, has written numerous ASTM test Schoff procedures and has championed the use of ASTM standards. He is currently Secretary of ASTM Committee D01 on Paints and Related Coatings, Materials and Applications. He is Chair of the Federation of Societies for Coatings Technology (FSCT) Publications Committee, a member of the Editorial Review Board, one of the technical editors of the Journal of Coatings Technology and Research and is active in the Pittsburgh Society for Coatings Technology. Schoff’s main research interests have involved physical testing and measurement, and their application to solving product and process problems and to developing new products, primarily in industrial and automotive coatings. He has developed lectures on surface defects, failure analysis, cure, rheological measurements, corrosion, pigment dispersion, surface preparation, optical microscopy and other related topics. He has taught short courses for FSCT, the Sociedad Argentina de Technólogos en Recubrimientos and at many universities. Schoff will receive the Tess Award during the 236th National Meeting of the American Chemical Society in Philadelphia, PA. He will present an award address at that time. The Tess Award is presented annually by the Division of Polymeric Materials: Science and Engineering in recognition of outstanding contributions to coatings science and technology. It is funded by a grant from Dr. and Mrs. Roy W. Tess. Nominations for the 2009 Roy W. Tess Award in Coatings are now being accepted; they are welcome from all sections of industry, academia and government. Nominations should be forwarded to Theodore Provder, Tess Award Chairman, at 26567 Bayfair Drive, Olmsted Falls, OH, 44138. All finalized nominations for the 2009 Tess Award should be submitted prior to September 1, 2008. For more information, contact Theodore Provder at tprovder@cox.net. Researchers Develop Low-Cost Technique for Producing Antimicrobial Paints NEW YORK — Researchers at the City College of New York (CCNY) and Rice University have developed a low-cost, environmentally friendly technique for embedding antimicrobial silver nanoparticles into vegetable oil-based paints. The method, reported in the March issue of Nature Materials, could give homes and workplaces a new defense against germs by applying a fresh coat of paint. Silver’s antibacterial properties have been known for thousands of years, and silver nanoparticles offer superior antibacterial activity while being non-toxic. However, coatings containing antimicrobial agents have failed commercially in the past due to their complex, multi-step preparation methods and high cost of production. The CCNY/Rice team developed a “green chemistry” approach to synthesize metal nanoparticles in common household paints in situ without using hazardous reagents and solvents. “We extensively worked on poly-unsaturated 10 APRIL 2008 | W W W . P C I M A G . C O M hydrocarbon chain containing polymers/oils to devise a novel approach to nanoparticle formation,” said George John, Professor of Chemistry at CCNY and lead author of the article. Poly-unsaturated hydrocarbons undergo auto-oxidationinduced crosslinking, which is similar to lipid peroxidation, the process by which fatty acids are oxidized in biological systems. During this process, a variety of chemically active species called free radicals are generated. These were used by the group as a tool to prepare metal nano-particles in situ in the oil medium. The nanoparticle-embedded coating can be applied like traditional paints to surfaces such as metal, wood, polymers, glass and ceramics. The metal nanoparticles show characteristic color but avoid the use of short-shelf-life organic-pigment paints. In addition, these coatings exhibited efficient antibacterial activity toward Escherichia coli and Staphylococcus aureus. The antibacterial property is important for hospitals and other public buildings that are prone to bacterial growth, a main cause of infection and disease. http://WWW.PCIMAG.COM
