  3. SPMW Mechanisms of atomic friction studied by friction force microscopy

    12 Dec 2006 | | Contributor(s):: Meyer

    Force microscopy is a versatile instrument to investigate physical phenomena on surfaces. The first emphasis is on the study of friction on the nanometer-scale, also called nanotribology. It will be shown that atomic-scale stick-slip is relatively well understood, where the dependence on velocity...

  4. On Modeling Metabolic Systems

    04 Jan 2007 | | Contributor(s):: Doraiswami Ramkrishna

    Modeling metabolism has been generally based on the numerouscellular reactions to be in steady state with respect to theexternal fluxes on the cell boundary. The essence of this"steady state" approach is the identification of all thereaction rates (fluxes), both external and internal to the...

  5. Plasmon-resonant Nanorods as Multifunctional Imaging Agents

    28 Dec 2006 | | Contributor(s):: Alexander Wei

    Gold nanorods have several outstanding characteristics as optical contrastagents for biomedical imaging. Their strong optical absorption atnear-infrared (NIR) frequencies can be used to generate contrast for opticalcoherence tomography (OCT) imaging, and is well matched for detectionmodalities...

  6. McCoy Lecture: Nanodevices and Maxwell's Demon

    04 Oct 2006 | | Contributor(s):: Supriyo Datta

    This is a video taped live lecture covering roughly the same material as lecture 1 of "Concepts of Quantum Transport". Video only.

  7. Materials Science on the Atomic Scale with the 3-D Atom Probe

    08 Nov 2006 |

    Some of the key goals of materials science and technology are to be able to design a material from first principles, to predict its behaviour, and also to optimise the processing route for its manufacture. In recent years, these goals have come closer to realisation, thanks in part to the...

  8. Potassium Channels: Conduction, Selectivity, Blockage, Inactivation, and Gating

    03 Nov 2006 | | Contributor(s):: Benoit Roux, NCN at Northwestern University

    The determination of the structure of the KcsA K+ channel fromStreptomyces lividan has made it possible to investigate the functionof a biological channel at the atomic level. Because of its structuralsimilarity with eukaryotic K-channels, investigations of KcsA areexpected to help understand a...

  9. The Limits of CMOS Scaling from a Power-Constrained Technology Optimization Perspective

    17 Oct 2006 |

    As CMOS scaling progresses, it is becoming very clear that power dissipation plays a dominant role in limiting how far scaling can go. This talk will briefly describe the various physical effects that arise at the limits of scaling, and will then turn to an analysis of scaling in the presence of...

  10. Nanoelectronic Architectures

    24 Feb 2005 |

    Nanoelectronic architectures at this point are necessarily speculative: We are still evaluating many different approaches to fabrication and are exploring unconventional devices made possible at the nano scale. This talk will start off with a review of some "classical" crossbar structures using...

  11. Information Theory and Cell/Nanoparticle Modeling

    03 Mar 2005 |

    Physico-chemical models of cells and nanoparticles are being developed for pure and applied studies. Nanoparticles are simulated by a Poisson-Boltzmann equation (for determining the electric force field in bioelectrolyte media) while an all atom-simulator is used to determine structure. Both...

  12. Autonomic Adaptation of Virtual Distributed Environments in a Multi-Domain Infrastructure

    11 Jul 2006 | | Contributor(s):: Ryan Riley, Dongyan Xu

    By federating resources from multiple domains, a shared infrastructure provides aggregated computation resources to a large number of users. With rapid advances in virtualization technologies, we propose the concept of virtual distributed environments as a new sharing paradigm for a multi-domain...

  13. History of Semiconductor Engineering

    28 Jun 2006 | | Contributor(s):: Bo Lojek

    When basic researchers started working on semiconductors during the late nineteen thirties and on integrated circuits at the end of the nineteen fifties, they did not know that their work would change the lives of future generations. Very few people at that time recognized the significance of...

  14. What Can We Learn About Doing Content-Based Educational Research on Teaching and Learning from the 30-Year History of Research in Chemical Education?

    07 Jun 2006 |

    This talk is based on the assumption that one of the functions of the National Center for Learning & Teaching is to promote basic research on teaching and learning within the content domain of nanoscale science and engineering. In order to understand what this might involve, we will look at...
