  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. Bifunctional Air Electrode Studies

    01 Apr 2016 | | Contributor(s):: Brian Demczyk, C. T. Liu

    This presentation outlines a number of fundamental and processing studies conducted on carbon-based bifunctional air electrodes

  3. Structure and Properties of Carbon and Boron Nitride Nanotubes

    10 Jan 2014 | | Contributor(s):: Brian Demczyk

    This presentation describes structure and mechanical property determinations on carbon and boron nitride (sp2-bonded) nanotubes , as deduced by transmission electron microscopy.

  4. Ripples and Warping of Graphene: A Theoretical Study

    08 Jun 2010 | | Contributor(s):: Umesh V. Waghmare

    We use first-principles density functional theory based analysis to understand formation of ripples in graphene and related 2-D materials. For an infinite graphene, we show that ripples are linked with a low energy branch of phonons that exhibits quadratic dispersion at long wave-lengths. Many...

  5. Graphite

    17 Apr 2010 | | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck

    Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. Graphene sheets are weakly bonded to other graphene layers above and below to form Graphite. The difference between two layers is approximately 0.335 nm [1].Graphite can...
