  1. Aluminum: a safe, economical, high energy density material for energy storage, transport and splitting water to make hydrogen on demand

    30 Mar 2009 | | Contributor(s):: Jerry M. Woodall

    In 1968, a team lead by the author discovered that liquid gallium saturated with aluminum at room temperature would split water into hydrogen gas, alumina and heat. More recently his current team has discovered that bulk, solid Al rich alloys will also split water in the same manner. Since 1)...

    Quantum Simulation of the Seebeck Coefficient and Electrical Conductivity in 1D Superlattice Structures using Non-Equilibrium Green's Functions

  3. ECE 495N Lecture 40: Thermoelectricity

    29 Dec 2008 | | Contributor(s):: Supriyo Datta

  4. Nanoscale Opto Thermo Electric Energy Conversion Devices

    28 May 2008 | | Contributor(s):: Ali Shakouri

    We review solid-state devices that allow direct conversion of heat into electricity. We describe fundamental and practical limits of conventional thermoelectric materials. Novel metal-semiconductor nanocomposites are developed where the heat and charge transport are modified at the atomic level....

  6. The Potential of Nanostructured Materials to Address the Challenge of a Sustainable Energy Resource

    14 Feb 2008 | | Contributor(s):: Mildred S. Dresselhaus

    An overview is presented on the grand challenges to the science community in the next few decades in meeting global energy needs for the 21st century. Major advances in our present capabilities will be needed for energy production and storage and for its conversion from one form to another....

  7. Microscale Ionic Wind for Local Cooling Enhancement

    26 Oct 2007 | | Contributor(s):: David B Go

    As the electronics industry continues to develop small, highly functional, mobile devices, new methods of cooling are required to manage the thermal requirements of the not only the chip but the entire system. Comfortable skin temperatures, small form factors, and limited power consumption are...

  8. Piezoelectric Transducers: Strain Sensing and Energy Harvesting (and Frequency Tuning)

    15 Jun 2007 | | Contributor(s):: Toshikazu Nishida

    Acoustic pressure or mechanical force sensing via piezoelectric coupling is closely related to the harvesting of electrical energy from acoustical and mechanical energy sources. In this talk, mesoscale and microscale piezoelectric transducers for acoustic and vibrational sensing and energy...

  9. The Energy Problem: What the Helios Project Can Do About It

    13 Jun 2007 | | Contributor(s):: Steven Chu

    Nobel Prize winner Steven Chu talks about the Helios Project for the 2007 'Science at the Theater' series at Berkeley Repertory Theater in Berkeley, California. He proposes an aggressive research program to transform the existing and future energy systems of the world away from technologies that...

  10. Solid-State Lighting: An Opportunity for Nanotechnologists to Address the Energy Challenge

    25 Apr 2007 |

    More than one-fifth of the electrical power consumed in the U.S. is used for general illumination. Much of this energy is wasted to heat filaments in incandescent lamps, a century-old technology with an efficiency of about 5%. Fluorescent lighting is more efficient, but problems of color...

  11. BNC Annual Research Symposium: Nanoscale Energy Conversion

    23 Apr 2007 | | Contributor(s):: Timothy S Fisher

    This presentation is part of a collection of presentations describing the projects, people, and capabilities enhanced by research performed in the Birck Center, and a look at plans for the upcoming year.
