Cleaner water, more efficient electricity among UH chemical research
Six presentations on docket at annual American Chemical Society meeting
HOUSTON – A half dozen University of Houston researchers will be making presentations, ranging from bacteria removal in water and quantum shuttles in electricity to defining career moments, at the 228th National Meeting of the American Chemical Society, Aug. 22 to 26 in Philadelphia.
Founded in 1876, the American Chemical Society (ACS) is a nonprofit, scientific, educational organization. Chartered by the U.S. Congress and the largest scientific society in the world, ACS is a leader in fostering chemical education and research, with an international membership of more than 159,000 chemists and chemical engineers.
Four members of the UH College of Natural Sciences and Mathematics (NSM) Department of Chemistry and two members of the UH Cullen College of Engineering (CCoE) Departments of Civil and Environmental Engineering and Chemical Engineering round out the University of Houston attendees.
Shankar Chellam, associate professor of civil and environmental engineering, will focus on mechanisms of bacteria removal from drinking water supplies using microfiltration membranes, with an emphasis on filter clogging. Eric Bittner, professor of chemistry, will speak about theoretical models for current-driven chemical dynamics in molecular wires. Randolph Thummel, professor of chemistry, will discuss how transition metal complexes are being designed and synthesized that would use sunlight to promote the catalytic decomposition of water into hydrogen and oxygen. Ramanan Krishnamoorti, associate professor of chemical engineering, will reveal the development of super-strength and lightweight fibers of nylon and other polyester-based polymers, as well as development of a new class of biodegradable and biocompatible polymer composites with enhanced mechanical properties that are lightweight for potential applications in biomedical devices and drug delivery using carbon nanotubes. P. Shiv Halasyamani, assistant professor of chemistry, will talk about the importance of seeking out mentors at every stage in one's scientific career, as well as discussing the rewarding experience of being a mentor. Ruifa Zong, post-doctoral fellow in the chemistry department, will elaborate on Thummel's research, particularly how transition metal complexes assist in the direct conversion of sunlight into electricity.
