In This Workshop

  1. Symposium on Nanomaterials for Energy: Coupled and Chiral Surface Plasmons in Metal Nanostructures

    14 May 2015 | Online Presentations | Contributor(s): K. George Thomas

    The presentation will provide examples of modulating the optical properties of nanomaterials by integrating them into higher order assemblies using electrostatic, supramolecular and covalent approaches. Various approaches to organize metal nanoparticles by varying the distance and geometry will...

  2. Symposium on Nanomaterials for Energy: Photonic Nanostructures for Enabling High-Efficiency Thermophotovoltaics

    14 May 2015 | Online Presentations | Contributor(s): Peter Bermel

    Thermophotovoltaic (TPV) systems generate electricity using heat drawn from one or more of a wide variety of sources, including sunlight, fossil fuels, and radioisotopes. They function as solid-state devices, in which heat is thermally radiated as photons onto TPV modules that generate...

  3. Symposium on Nanomaterials for Energy: An Electrical Rectifier Based on Au Nanoparticle Array

    11 May 2015 | Online Presentations | Contributor(s): Giridhar U Kulkarni

    In contrast to the ‘colloidal state’, metal nanoparticles assembled onto a substrate as an ordered array represent a quasi 2D system where the interparticle coupling, depending on its strength, can give rise to collective properties, unique to the nanoparticle organisation. Thus, metal...

  4. Symposium on Nanomaterials for Energy: Graphene-Based Materials for Potential Energy Applications

    11 May 2015 | Online Presentations | Contributor(s): Yong P. Chen

    I will discuss our studies of large scale CVD (chemical vapor deposition) grown graphene, graphene-quantum dot hydrids as well as graphene-based composites. I will discuss their electronic, thermal and optoelectronic properties and potential implications for graphene based energy applications

  5. Symposium on Nanomaterials for Energy: Thermal Transport in Nanostructures: A Multiscale Multiphysics Approach

    11 May 2015 | Online Presentations | Contributor(s): Xiulin Ruan

    Thermal transport is a key issue limiting many important energy transfer and conversion applications such as heat dissipation in electronic devices and thermoelectric energy conversion. In this talk I will show how phonon thermal transport can be controlled using boundary, interface, and...

  6. Symposium on Nanomaterials for Energy: Surface Functionalization Using Molecular Ions

    11 May 2015 | Online Presentations

    Molecular ions interact with surfaces in the hypothermal energy range (5-100 eV) by a variety of physical and chemical processes which will be demonstrated. Ion deposition at surfaces (“soft-landing” (SL)) and reactive scattering can be used to introduce chemical functionality of choice at...

  7. Symposium on Nanomaterials for Energy: Structure, Topological Defects, Vibrations and Rippling of Graphene, C1-2x(BN)x and MoS2: First-principles Studies

    11 May 2015 | Online Presentations | Contributor(s): Umesh V. Waghmare

    We present first-principles theoretical investigations of structure, topological defects and vibrational properties of 2-dimensional materials such as graphene, solid solution BCN of graphene and BN, and MoS2, and identify Raman spectral signatures of various deviations from their ideal forms....

  8. Symposium on Nanomaterials for Energy: Nanostructured Thermoelectric Materials for Waste Heat Recovery

    11 May 2015 | Online Presentations | Contributor(s): Ali Shakouri

    Energy consumption in our society is increasing rapidly. A significant fraction of the energy is lost in the form of heat. In this talk we introduce thermoelectric devices that allow direct conversion of heat into electricity. Novel metal-semiconductor nanocomposites are developed where the heat...

  9. Symposium on Nanomaterials for Energy: Graphitic Petals for Electrochemical Charge Storage

    11 May 2015 | Online Presentations | Contributor(s): Ron Reifenberger

    The need for high-density electrochemical energy storage in today’s world is self-evident, and we have investigated the advantages offered by graphitic petals (GPs) to achieve this end. The controlled growth of GPs permits nano-texturing of a substrate, producing an enhanced carbon-based...
