  1. [Illinois] Interphase Chemical Mapping Of Carbon Fiber-epoxy Composites By Afm-ir Spectroscopy

    13 Apr 2017 | Contributor(s):: Chris Montgomery

    The properties and performance of carbon fiber reinforced polymer matrix composites are highly influenced by the chemical interactions of the fiber/matrix interface region. Many researchers have hypothesized that the presence of carbon fibers in epoxy causes a chemical gradient to form around...

  2. [Illinois] Rutherford Backscattering Spectroscopy

    18 Aug 2015 | | Contributor(s):: Timothy P. Spila

  3. [Illinois] Secondary Ion Mass Spectroscopy

    18 Aug 2015 | | Contributor(s):: Timothy P. Spila

  4. [Illinois] CNST 2012: Applied Nanotechnology for Foodborne Pathogen and Toxin Detection

    02 Jun 2013 | | Contributor(s):: Bosoon Park

  5. Excited State Spectroscopy of a Quantum Dot Molecule

    11 Jan 2013 | | Contributor(s):: Muhammad Usman

    Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experimentally observed excitonic spectrum by Krenner et al (Phys. Rev. Lett. 94 057402, 2005) is quantitatively reproduced,...

  6. 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...

  8. 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...

  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...
