Seminar

Advanced electronic structure theories for strongly correlated electrons

Monday, February 1, 2016, 4:00 PM - 5:00 PM
Francesco Evangelista, Ph.D., Assistant Professor, Department of Chemistry, Emory University

States of matter in which the motion of electrons is strongly correlated are a fascinating, yet challenging, area of chemistry and physics. From the perspective of chemistry, strong electron correlation is accompanied by the mixing of near-degenerat more  »

Seminar

The wonders of electron density: from half an electron to noncovalent interactions of biomolecular complexes

Wednesday, January 27, 2016, 4:00 PM - 5:00 PM
Weitao Yang, Ph.D., Philip Handler Professor, Duke University

Interactions between electrons determine the structure and properties of matter from molecules to solids. To describe interacting electrons, the simple three-dimensional electron density can be used as the basic variable within density functional the more  »

Seminar

“Three-layer Regulation Leads to Diverse and Monoallelic Olfactory Receptor Expression”

Tuesday, January 26, 2016, 12:30 PM - 1:30 PM
Jianhua Xing, Associate Professor, Department of Computational and Systems Biology, University of Pittsburgh

Abstract: Multiple-objective optimization is common in biological systems. In the mammalian olfactory system, each sensory neuron stochastically expresses only one out of up to thousands of olfactory receptor (OR) gene alleles; at organism level the more  »

Seminar

Dynamic Interfaces for Biological and Chemical Sensing

Monday, January 25, 2016, 4:00 PM - 5:00 PM
Timothy M. Swager, Ph.D., John D. MacArthur Professor, Massachusetts Institute of Technology, Dept. of Chemistry

This lecture will focus on the design of systems wherein a reconfiguration of the materials can be triggered chemically of mechanically. The utility of these methods is to generate transduction mechanisms by which chemical and biological sensors can more  »

Development of iron oxide nanomaterials-based technology for arsenic remediation

Monday, January 25, 2016, 2:30 PM - 4:30 PM
Natalia Gonzalez Pech, Doctoral Candidate

In 2005, the Colvin group proposed the use of magnetite nanoparticles for arsenic adsorption. This would allow the reduction of waste significantly with the additional advantage of magnetic-driven separation at low fields. However, despite the effort more  »

Seminar

"Monomer Dynamics Control the First Steps of Aggregation and Folding"

Tuesday, January 19, 2016, 12:30 PM - 1:30 PM
Lisa Lapidus, Professor, Departments of Physics & Astronomy and Biochemistry & Molecular Biology, Michigan State University

Abstract: An important aspect of protein folding is understanding how folding competes with aggregation, which leads to diseases such as Parkinson’s and Alzheimer’s. The complexity and dynamics of unfolded protein ensembles may be the ultimate speed more  »

Seminar
