Klaus D. Sattler, Ph.D., has been a professor of physics at the University of Hawaii, Honolulu for 27+ years. He has conducted atomic cluster research at the University of Konstanz, Germany; served as a Heisenberg fellow at the University of California, Berkeley; and studied the formation of polycyclic aromatic hydrocarbons and nanoparticles in hydrocarbon flames in collaboration with the Swiss Federal Institute of Technology (ETH), Zurich. His current work focuses on novel nanomaterials and solar photocatalysis with nanoparticles for the purification of water. He is the editor of Fundamentals of Picoscience (CRC Press, 2014) and the seven-volume Handbook of Nanophysics (CRC Press, 2011). Among his many accomplishments, Dr. Sattler was awarded the German Physical Society’s prestigious Walter Schottky Prize in 1983.
