  1. "Ab Initio" Theory of Novel Micro and Nanolasers

    19 May 2008 | | Contributor(s):: A. Douglas Stone

    While the laser is one of the most important inventions of the past century and one of the most interesting and controllable non-linear systems in physics, there is surprisingly little predictive theory of lasing properties. Predicting lasing thresholds and output power far above threshold in...

  2. <i>In Vivo</i> Nuclear Magnetic Resonance Imaging and Spectroscopic Investigations of Structure and Function of Rodent Brain

    30 Jul 2008 | | Contributor(s):: Anant B. Patel

    Nuclear Magnetic Resonance Imaging (MRI) is a powerful and a versatile imaging modality for non-invasive characterization of host structure and function. MRI has grown in many directions such as functional MRI, diffusion tensor imaging, chemical shift imaging, which is used to detect single...

  3. A 3D Quantum Simulation of Silicon Nanowire Field-Effect Transistors

    17 Jan 2006 | | Contributor(s):: Mincheol Shin

    As the device size of the conventional planar metal oxide semiconductor field effect transistor(MOSFET) shrinks into the deep sub micron regime, the device performance significantly degradesmainly due to the short-channel effect. The silicon nanowire field-effect transistor (SNWFET) isconsidered...

  4. A New Terahertz Heterodyne Detector Based on Single-Walled Carbon Nanotubes

    27 Jul 2005 |

    We present non-invasive methods for improving the sensitivity of label-free biosensors that offer the advantage of rapid and real-time detection but suffer from relatively low sensitivity. We present detection of cancer markers using the Quartz Crystal Microbalance and demonstrate that 2...

  5. A Novel Diagnostic Assay Based On Nanomechanics

    28 Jul 2005 |

    Micro-fabricated silicon cantilevers arrays offer a novel label-free approach where ligand-receptor binding interactions occurring on the sensor generate nanomechanical signals like bending or a change in mass that is optically detected in-situ. We report the detection of multiple unlabelled...

  6. A Personal Quest for Information

    19 Feb 2004 |

    This talk will report results and conclusions from my personal investigations into several different disciplines, carried out with the unifying intent of uncovering some of the fundamental principles that govern representation, processing, and the communication of information. The specific...

  7. A Vision for the Digital Data Universe

    AC Electrokinetic and Nonlinear Optical Probes of Biological Interactions

  9. Active Photonic Nanomaterials: From Random to Periodic Structures

    06 Feb 2006 | | Contributor(s):: Hui Cao

    Active photonic nanomaterials, which have high gain or large nonlinearity, are essential to the development of nanophotonic devices and circuits. In this talk, I will provide a review of our recent research activities related to the fabrication of active photonic nanomaterials and the...

  10. Addressing Molecular Dynamics Time-scale Issues to Study Atomic-scale Friction

    12 Oct 2010 | | Contributor(s):: Ashlie Martini

    This presentation will include an introduction to several accelerated molecular dynamics methods. However, particular focus will be given to parallel replica (ParRep) dynamics in which atomistic simulations are run parallel in time to extend their total duration. The ParRep method is based on...

  11. Affordable Clean Energy: Challenges and Opportunities

    20 Oct 2008 | | Contributor(s):: Hukam C. Mongia

    The technical presentation is built around the August 9th 2008 ABC News/Planet Green/Stanford Poll on Environment/Energy in which the majority of the people polled expressed support for the following ideas: increase fuel efficiency standards, allowing drilling offshore, people and businesses are...

  12. 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)...

  13. Amine Linked Single Molecule Circuits: Systematic Measurements & Understanding

    02 Jul 2007 | | Contributor(s):: Mark S Hybertsen

    Formation and function of well-defined linkages between organic molecules and metallic electrodes has been a key issue in the field of molecular electronics. We recently discovered that the conductance of single molecule junctions formed using gold-amine linkages can be measured reliably and...

  14. An Electrical Engineering Perspective on Molecular Electronics

    26 Oct 2005 | | Contributor(s):: Mark Lundstrom

    After forty years of advances in integrated circuit technology, microelectronics is undergoing a transformation to nanoelectronics.
