March 15, 2018 ChBE Seminar Speaker – Dr. Reginald Rogers from the Rochester Institute of Technology

March 14, 2018

The Department of Chemical and Biomolecular Engineering welcomes Dr. Reginald Rogers, Assistant Professor from the Rochester Institute of Technology, as a part of the ChBE Spring Seminar series. His seminar, titled “Got Clean Water? How Carbon Nanomaterials Play a Role in Achieving this Grand Challenge,” will take place on Thursday, March 15th, 2018 from 2:00-3:00pm in Earle 100.

Water is considered to be the most precious commodity on the planet, and one that needs to be treated with respect. With the ever growing world population, there is an increasing need to develop new materials and systems that can potential improve the quality of water on longer time scales. Newly emerged nanomaterials, such as graphene or carbon nanotubes, are of increasingly widespread importance in environmental remediation, especially in their ability to remove undesirable chemicals from hydrological systems. In this presentation, an in-depth overview of the use of next generation carbon-based nanomaterials for adsorption applications will be discussed. Aqueous-phase adsorption of multiple organic compounds and heavy metal ions at environmentally relevant concentrations by granular activated carbon and graphene-single- walled carbon nanotube free-standing hybrid papers will be presented. Results show that the hybrid nanocomposites have superior adsorption capacities compared to bulk carbonaceous materials with up to 35% and 170% larger uptakes towards aromatic and ionic compounds, respectively. In addition, the use of highly porous, lightweight aerogels as adsorbents of high bonding affinity for a large variety of chemicals provide opportunities for enhanced separation processes. In particular, the nature and the amount of nanostructures (graphene, multi-walled or single-walled carbon nanotubes) along with their dispersion state throughout the carbonaceous matrix strongly influence the adsorption properties of the aerogel. Finally, an outlook on the use of sorted carbon nanotubes for adsorption applications will be shared.

Dr. Reginald E. Rogers is an Assistant Professor in Chemical Engineering at the Rochester Institute of Technology.  He is head of the Nanoscale Energy and Separation Materials Laboratory (NESML).  Dr. Rogers and his group have been involved in a variety of projects investigating the separation of organic and inorganic compounds from aqueous environments using carbon-based nanomaterials.  Dr. Rogers also has projects focused on the development of cathode materials for sodium ion batteries. He has served as a co-author on over 25 research papers and has presented at many national conferences. Dr. Rogers has been recognized for his teaching, research, and service contributions with numerous awards and recognitions. Notable awards include the 2016 Richard and Virginia Eisenhart Provost’s Award for Excellence in Teaching from RIT, the 2017 Henry C. McBay Outstanding Teacher Award from the National Organization for the Professional Advancement of Black Chemists and Chemical Engineers, the 2017 Emerging Investigator honor by Environmental Science: Water Research Camp; Technology from the Royal Society of Chemistry, and most recently, the 2018 Dr. Janice A. Lumpkin Educator of the Year Award from the National Society of Black Engineers.
