Orbital Mediated Tunneling in a New Unimolecular Rectifier
0.0 out of 5 stars
25 May 2007 | Online Presentations | Contributor(s): Robert Metzger, NCN at Northwestern University
In 1997 we showed that hexadecylquinolinium tricyanoquinodimethanide is a unimolecular rectifier, by scanning tunneling microscopy and also as a Langmuir-Blodgett (LB) monolayer, sandwiched between Al electrodes. We have now seen rectification in a new molecule: this rectification can be...
Renormalization Group Theories of Strongly Interacting Electronic Structure
20 Apr 2007 | Online Presentations | Contributor(s): Garnet Chan, NCN at Northwestern University
Our work is in the area of the electronic structure and dynamics of complex processes. We engage in developing new and more powerful theoretical techniques which enable us to describe strong electronic correlation problems.Of particular theoretical interest are the construction of fast...

Potassium Channels: Conduction, Selectivity, Blockage, Inactivation, and Gating
03 Nov 2006 | Online Presentations | Contributor(s): Benoit Roux, NCN at Northwestern University
The determination of the structure of the KcsA K+ channel fromStreptomyces lividan has made it possible to investigate the functionof a biological channel at the atomic level. Because of its structuralsimilarity with eukaryotic K-channels, investigations of KcsA areexpected to help understand a...
