  1. Metamaterials: A New Paradigm of Physics and Engineering

    01 May 2008 | | Contributor(s):: Vladimir M. Shalaev

    Three part lecture on metamaterials. Metamaterials are expected to open a gateway to unprecedented electromagnetic properties and functionality unattainable from naturally occurring materials, thus enabling a family of new “meta-devices”. In these three lectures, we review this new emerging...

  2. Microphone Selection and Comparison: Hear the Difference

    08 Aug 2006 | | Contributor(s):: Joseph M. Cychosz

    Selecting a microphone can be a difficult task.For presentations, the quality is very much dependent upon the audio clarity and quality of the naration. For meetings, quality can be somewhat less. This presentation gives an audio comparison of the various options listed with our Microphone...

  3. Microstructural Design of Electrically Active Materials and Devices Through Computational Modeling: The OOF Project

    20 Jan 2009 | | Contributor(s):: R. Edwin Garcia

    We present an overview of a public domain program, the Object Oriented Finite Element analysis (OOF), which predicts macroscopic behavior, starting from an image of the microstructure and ending with results from finite element calculations. The program reads an image (or a sequence of images)...

  4. Modeling and Analysis of VLSI Interconnects

    10 May 2007 | | Contributor(s):: Cheng-Kok Koh

    With continual technology scaling, the accurate and efficient modeling and simulation of interconnect effects have become problems of central importance.

  7. Modern X-ray Scattering Methods for Nanoscale Materials Analysis

    15 Oct 2008 | | Contributor(s):: Richard J. Matyi

    Since its discovery by von Laue in 1912, X-ray diffraction has become an indispensable tool for structure determinations in the physical and biological sciences. X-rays are characterized by high energies and by wavelengths that are commensurate with nanometer-sized structures – unlike optical...

  8. Molecular Interferometry

    26 Jun 2007 | | Contributor(s):: David D. Nolte

    While single-molecule detection through fluorescence has now become common-place, there has been no analogous single-molecule capability using direct detection approaches such as interferometry. This limitation is slowly yielding to high-speed interferoemtric detection that is pushing the...

  9. Moore's Law Forever?

    13 Jul 2005 | | Contributor(s):: Mark Lundstrom

    This talk covers the big technological changes in the 20th and 21st century that were correctly predicted by Gordon Moore in 1965. Moore's Law states that the number of transistors on a silicon chip doubles every technology generation. In 1960s terms that meant every 12 months and currently this...

  10. MPI for the Next Generation of Supercomputing

    05 Dec 2008 | | Contributor(s):: Andrew Lumsdaine

    Despite premature rumours of its demise, MPI continues to be the de facto standard for high-performance parallel computing. Nonetheless, supercomputing software and the high-end ecosystem continue to advance, creating challenges to several aspects of MPI. In this talk we will review the design...

  11. Multigrid Tutorial

    08 Jun 2010 | | Contributor(s):: Dragica Vasileska

    This set of slides describe the idea behind the multigrid method and its implementation.

  12. Multiphase Gallium Nitride Nanowires and Nanocircuits

    04 Feb 2008 | | Contributor(s):: Virginia M. Ayres

    Catalyst-free vapor-solid nanowire growth, a newly described method for the production of nanowires compatible with a wide variety of semiconductor materials, has been used to produce novel multiphase zinc-blende/wurtzite gallium nitride nanowires. Orientation relation-ships within the...

  13. Nano*High: Nature's Nasty Nanomachines: How Viruses Work, and How We Can Stop Them

    25 Sep 2010 | | Contributor(s):: Carolyn R. Bertozzi

    The birth and growth of nanotechnology is only a few decades old, whereas Nature has been building nano-machines for millennia. Viruses are marvels of natural nano-engineering, but can pose a problem for human health. To combat these nano-machines, scientists are turning to recent developments...

  14. Nano*High: X-rays, Lasers, and Molecular Movies

    25 Sep 2010 | | Contributor(s):: Roger W. Falcone

    X-ray imaging is an excellent method to make visible what would normally be invisible - who hasn't had an X-ray at the doctor or dentist's office before? At the Lawrence Berkeley National Lab, the Advanced Light Source is a gigantic X-ray imaging machine. Dr. Roger Falcone discusses X-ray...
