Montgomery College Hosts Spectrum Lecture on Nanoparticles in Aquatic Environments
Chemical Engineer, Dr. R. David Holbrook, to Talk at Germantown Campus, April 6

Dr. R. David Holbrook, a research chemical engineer, will speak about nanoparticles in aquatic environments at Montgomery College-Germantown on Monday, April 6 at 7:30 p.m. The event with Dr. Holbrook, who works for the Surface and Microanalysis Science Division at the National Institute of Standards and Technology, will take place in Globe Hall, which is located in the High Technology and Science Center, 20200 Observation Drive, Germantown, Md. This event is free and open to the public.

Like all Spectrum Lectures, Dr. Holbrook’s presentation is designed for a non-scientific audience, enabling scientists, students and the community to learn about ground-breaking advancements in science. In his talk, Dr. Holbrook will speak about the behavior of engineered nanoparticles in aquatic systems. Nanoparticles are microscopic particles of something such as a metal, polymer, or oxide, with dimensions in the nanometer range. They are influenced by three main factors: the physiochemical conditions encountered in the environment; the nanoparticles' bioavailability; and any transformation that may occur during biological uptake and excretion. The objective of this presentation is to provide an overview of these three factors as they apply to the fate, transport, and bioavailability of engineered nanoparticles.

R. David Holbrook received a B.S. from Cornell University and a Ph.D. in civil engineering from Virginia Polytechnic Institute and State University (Virginia Tech). Dr. Holbrook also worked for six years designing biological wastewater facilities.  He has authored or co-authored over 20 peer reviewed manuscripts and has presented his work at conferences and workshops around the world.
