  1. Nanoscale Spectroscopy and Plasmonics in Infrared

    19 Apr 2012 | | Contributor(s):: Mikhail Belkin

    In this talk, I will present the results of two of our research projects. I will start with a simple technique for nanoscale mid-infrared spectroscopy that we have developed recently. Subwavelength resolution is achieved by detecting optical absorption through measuring local photothermal...

  3. Large-scale first principles configuration interaction calculations of optical absorption in boron clusters

    07 Mar 2012 | | Contributor(s):: Ravindra L Shinde

    We have performed systematic large-scale all-electron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each clus-ter were considered, and their geometries were optimized at the coupled-cluster singles doubles(CCSD)...

  5. Peanuts vs. Pyramids: Two Perspectives on MEMS

    29 Dec 2009 | | Contributor(s):: Stephen D. Senturia

    MEMS, the acronym for Micro-electromechanical Systems, also known simply as “Micro-systems,” come in two main types: commodity products (the peanuts) and MEMS-enabled products (the pyramids, or, more correctly, the inverted pyramids). The economics of scale greatly affect how these two classes of...

    14 Apr 2009 | | Contributor(s):: Baudilio Tejerina, Joshua Telser

    This program calculates the powder pattern EPR spectra of a 2-spin electronic system.

  9. Carbon Nanotechnology: Scientific and Technological Issues

    24 Feb 2008 | | Contributor(s):: Joe Lyding

    Carbon nanotechnologies based on single-walled carbon nanotubes (SWNTs) and graphene (a single atomic layer of graphite) are being pursued for a wide range of technological applications ranging from chemical sensing to post-silicon nanoelectronics. A common thread is the need to atomistically...

  10. Modeling (Semi) Unstructured Proteins

    26 Mar 2008 | | Contributor(s):: Michael Colvin

    The past century has seen tremendous progress in determining the biochemical and biophysical processes that constitute life. One exciting consequence of this understanding is the possibility of developing mathematical models of biological function that are accurate and even predictive. My...

  11. Spectroscopy and Modeling to Infer Channel Structure and Function

    23 Mar 2008 | | Contributor(s):: Vishwanath Jogini

    We are particularly interested in issues about ion permeation, ion selectivity, gating, and channel inhibitors. We are currently working on the KcsA channel, the OmpF porin, and the gramicidin A> channel. We are also spending our efforts in the development of new computational approaches for...
