Teaching old proteins new tricks: Engineering metalloenzymes for energy conversion reactions

Wednesday, May 3, 2017, 4:00 PM - 5:00 PM
Hannah Shafaat, Ohio State University

The impending energy crisis is one of the biggest challenges that scientists of today face. At the root of this problem lie the dual issues of limited fossil fuel supplies and rising CO2 levels, both of which threaten severe ecological damage. On a m more  »



Ab initio free energy calculations for adsorption and reactions in nanoporous systems

Wednesday, April 26, 2017, 4:00 PM - 5:00 PM
Joachim Sauer, Professor of Chemistry, Humboldt University Berlin

The ab initio prediction of reaction rate or equilibrium constants for systems with hundreds of atoms with an accuracy that is comparable to experiment is a challenge for computational quantum chemistry. We present a divide-and-conquer strategy that more  »


ECE Brice Distinguished Lecture: "Novel Materials for Next Generation Photonic Devices," Dr. Michal Lipson, Columbia University, (698/699)

Tuesday, April 18, 2017, 4:00 PM - 5:00 PM
Michal Lipson, Professor, Electrical and Computer Engineering, Columbia University

Ultrafast optoelectronics devices, critical for future telecommunication and data ultra-high speed communications and data communications, have been limited in speed due to nature of the materials forming the devices. Only very few materials can be u more  »


"Architecture of Myosin V and its Motility”

Tuesday, April 18, 2017, 12:30 PM - 1:30 PM
Dave Thirumalai, Robert A. Welch Chair in Chemistry, University of Texas, Austin

Abstract: Myosin V, two-headed motor protein and a member of the myosin super family, ferries cellular cargo by walking hand-over-hand on actin filaments. Interplay between ATD-driven conformational changes in the motor head and stress due to load p more  »


Single-Molecule Spectroscopy with Catalysts, Conductive Polymers, and Optical Microresonators

Wednesday, April 12, 2017, 4:00 PM - 5:00 PM
Randall Goldsmith, Assistant Professor of Chemistry, University of Wisconsin-Madison

Measurements on individual molecules have revolutionized how chemists can perceive molecular properties and dynamics, yet single-molecule techniques can only be applied with considerable experimental constraints. The Goldsmith group develops new too more  »


“Division of Labor Among the Subunits of a Highly Coordinated Ring ATPase”

Tuesday, April 11, 2017, 12:30 PM - 1:30 PM
Carlos Bustamante, Professor, Stanford School of Medicine

Abstract: As part of their infection cycle, many viruses must package their newly replicated genomes inside a protein capsid. Bacteriophage phi29 packages its 6.6 mm long double-stranded DNA using a pentameric ring nano motor that belongs to the ASC more  »

Advanced Quantitative Analysis of Single-Walled Carbon Nanotubes

Monday, April 10, 2017, 3:00 PM - 5:00 PM
Yara Kadria-Vili, Doctoral Candidate

Single-walled carbon nanotubes (SWCNTs) have promised wide range of novel applications for containing a mixture of many tubular structures that vary in diameter size, chiral angles, and physical properties. However, their usage has been hindered by s more  »

Lecture/Lecture Series

Ken Kennedy Award Lecture: "MPI: The Once and Future King" presented by Dr. William Gropp

Tuesday, April 4, 2017, 4:00 PM - 5:00 PM
Dr. William Gropp, Acting Director and Chief Scientist at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign and the Paul and Cynthia Saylor Professor in the Department of Computer Science, University of Illinois at Urbana-Champaign

The Message Passing Interface (MPI) has been the dominant programming system for expressing highly-parallel technical applications for over 20 years. This success was due in part to a combination of careful design of the standard by the MPI Forum an more  »


“Modeling the Emergence of Clones in Populations (By Drawing Analogies with the Physics of Glasses) and the Adaptive Immune System of Bacteria (Called CRISPR)”

Tuesday, April 4, 2017, 12:30 PM - 1:30 PM
Marija Vucelja, Assistant Professor, University of Virginia

Abstract: I will present two population genetics stories where analogies from physics have been pivotal. First, I will talk about the emergence of clones in populations. Recombination reshuffles genetic material, while selection amplifies the fittest more  »

Size and Shape Control of Colloidal Al Nanocrystals for UV Plasmonics Applications

Monday, April 3, 2017, 10:30 AM - 12:30 PM
Michael McClain, Doctoral Candidate

Al nanocrystals are a cost-effective alternative to noble metal nanomaterials with their own unique plasmonic features throughout the UV, visible, and infrared spectrum. In the past two decades, generalized rules for nanocrystal growth have been esta more  »
