When granular materials flow, the particles rub against one another and other surfaces and become electrostatically charged. The electrostatic charge can be beneficial (e.g., in digital printing) or detrimental (e.g., disrupting industrial operations). This charging occurs by the same process that leads to the shock you feel when you touch a doorknob after … Read the rest »
Upcoming Seminars
“Tuning Surface Properties by Chemical Functionalization” by Dr. Andrew Teplyakov, University of Delaware
Dr. Teplyakov will discuss how surfaces and interfaces play an important role in development of modern microelectronics, optoelectronics, biosensing and other fields.
This seminar will cover approaches to tune the properties of interfaces, surfaces, and subsurface layers of participating materials by chemical functionalization. Specifically, the amino-groups of a general formula NHx used to control surface … Read the rest »
“Develop new methods for synthesizing nanostructured materials” by Dr. Lea Hildebrandt of Carnegie Mellon University
This seminar talks about how atmospheric nanoparticles (aerosols) adversely affect human health, perturb Earth’s climate and degrade visibility.
Organic aerosol globally comprises a significant fraction (20-90%) of the submicron particle mass. Three-dimensional chemical transport models often significantly under-predict the concentration and oxidative state of organic aerosol, suggesting that today’s understanding of organic aerosol is incomplete.
