Guest Speaker: Dr. Andrey Zakharchenko

Heart disease remains the leading cause of death worldwide. Heart valve disease is life-threatening in which heart valves do not function properly. Surgery is required to repair or replace the damaged valve for severe valve disease. Bioprosthetic heart valves are made from animal-derived materials, such as bovine pericardium (BP) or porcine heart valves, often work for many years in adults. However, when used in children, they tend to fail as…


A Hitchhiker’s Guide to High-Accuracy Computational Quantum Chemistry for Hydrogen Bonding, Halogen Bonding and other Non-Covalent Interactions

The subjects of solvation, molecular recognition and supramolecular self-assembly provide some of the motivation and impetus for the work that is the focus of the talk. Convergent approaches to quantum mechanical (QM) ab initio electronic structure calculations have provided tremendous insight into the structures, energetics and spectroscopic signatures of molecular clusters held together by relatively weak, non-covalent interactions (London…


2023 Alumni Lecture

Our 2023 Alumni Lecture speaker, Dr. Stefanie Milam, is a Planetary Scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and serves as the James Webb Space Telescope Deputy Project Scientist for Planetary Science. She works in the Astrochemistry Laboratory at the NASA Goddard Space Flight Center, and is an expert in rotational spectroscopy, observations, and laboratory modeling of astrochemistry and molecular astrophysics of…


Chemical and Physical Properties of Surfactants in Seawater and Aerosol Particles and Their Influence on Particle Hygroscopic Growth

The size and composition of atmospheric aerosol particles modulate their interactions with solar radiation, and thus their influence on climate and visibility. The radiative effects of aerosol particles remain a large uncertainty in accurately modeling and predicting current and future climates. Recent work has demonstrated the presence of organic surfactant molecules in atmospheric aerosol particles, and their sources and transformations in the…


From Molecular Gyroscopes to Homeomorphic Isomerization: Molecules that Turn Themselves Inside-Out

Children never cease to be fascinated by toy gyroscopes, which commonly consist of (1) a rotating axis and disk, and (2) two to four spokes that connect the termini of the axis. This talk will describe syntheses of molecules that duplicate the connectivity, symmetry, and rotational ability of such gyroscopes. Complexes with trans R3P-MLn -PR3 linkages are first prepared, with R groups that terminate with a CH=CH2 moiety. Then alkene metathesis…


Active Learning Approaches and Examples

The definition of active learning depends on who you ask.  The approaches are widely varying with different levels of student success. Today’s presentation will be a discussion of what constitutes active learning.  To help illustrate the concept, activities will be presented that are used in the presenter's classroom. It is hoped that attendees will leave with a better understanding of how active learning can be implemented in their…
