  1. Nanotechnology-Enabled Direct Energy Conversion

    25 Mar 2005 | | Contributor(s):: Gang Chen

    Energy transport in nanostructures differs significantly from macrostructures because of classical and quantum size effects on energy carriers such as on phonons, electrons, photons, and molecules. Nanoscale effects can be tailored to develop more efficient direct energy conversion technologies...

  2. Computer-Aided Analysis and Design of Bio-molecules

    10 Mar 2005 |

    Computer simulation of bio-molecules has become a valuable tool for the pharmaceutical industry, promising not only the potential to predict binding affinities for trial drugs, but also the ability to probe molecular interactions in ways that lab experiments cannot. This seminar will present one...

  3. Self-Heating and Scaling of Silicon Nano-Transistors

    05 Aug 2004 | | Contributor(s):: Eric Pop

    The most often cited technological roadblock of nanoscale electronics is the "power problem," i.e. power densities and device temperatures reaching levels that will prevent their reliable operation. Technology roadmap (ITRS) requirements are expected to lead to more heat dissipation problems,...

  4. Exponential Challenges, Exponential Rewards - The Future of Moore's Law

    14 Dec 2004 |

    Three exponentials have been the foundation of today's electronics, which are often taken for granted—namely transistor density, performance, and energy. Moore's Law captures the impact of these exponentials. Exponentially increasing transistor integration capacity, and exponentially...

  5. Single Electron Switching with Nano-Electromechanical Systems and Applications in Ion Channel Transport

    01 Nov 2004 | | Contributor(s):: Robert H. Blick

    Taking classes in physics always starts with Newtonian mechanics. In reducing the size of the objects considered however the transition into the quantum mechanical regime has to occur. The 'mechanics' of quantum mechanics is best studied in nano-structured semiconductor systems often termed...

  6. Bioinformatics and Systems Biology: At the Crossroads of Biology, Engineering, and Computation

    08 Oct 2004 |

    Traditional biological research has relied on a "deconstructive" mode where piece-wise analysis of the components of complex systems was carried out in detail. The genome projects have spurred the discovery of new genes/molecules to add to the existing inventory of "parts" that make up living...

  7. Interfacing Carbon Nanotubes with Biological Systems: From Biosensors to Cellular Transporters

    21 Oct 2004 |

    This talk will discuss two relatively new topics in carbon nanotube research. The first is nanotubes for chemical and biological sensors, an exploration motivated by the ultra high surface area of single walled carbon nanotubes and the need for label free electronic detectors for a wide range of...

  8. Construction of an Imitating Nano-motor Driven by Six ATP-binding RNAs of Bacterial Virus phi29

    02 Dec 2004 |

    A switchable imitating DNA-packaging motor was constructed in the laboratory. The motor is driven by six synthetic ATP-binding pRNA (packaging RNA) molecules that bind to the connector and function in a manner similar to the driving of a bolt with a hex nut. Conformational change and sequential...

  9. Computational Prototyping Tools For Biological Applications

    03 Dec 2004 |

    Computational tools are playing a rapidly expanding role in biology, both for engineering design and in exploratory science. The main reason is that the dramatic improvements in the measurement and mathematical modeling of basic biochemical and biological processes is making it possible to...

  10. Turbocharge Your Scientific Applications with Scripting

    29 Apr 2004 | | Contributor(s):: Michael McLennan

    Scientific applications are built with great care and attention to the core simulation algorithms, often with some input/output added as an afterthought. Instead, you can create a much more powerful tool with little extra effort by replacing the usual "main" program with an embedded scripting...

  11. Nanosystems Biology

    10 Sep 2004 |

    As we enter the 21st century, we stand at a major inflection point for biology and medicine-the way we view and practice these disciplines is changing profoundly. These changes are being driven by systems biology, a new approach to biology, and which will increasingly transform medicine from...

  12. Multiscale Modeling of the Mechanical Behavior of Polymer-Based Nanocomposites

    25 Mar 2004 |

    Polymers filled with nanoscale fillers (carbon nanotubes or nanoparticles) exhibit enhanced properties compared with the neat polymer and with the polymer filled with micron-sized fillers at same volume fraction. Most interestingly, combinations of exceptional properties may be obtained as, for...

  13. Vertically Aligned Carbon Nanotube for Interconnects and Nanoelectrode Based Biosensors

    15 Apr 2004 |

    In the past few years, tremendous progress in the growth of carbon nanotubes (CNTs) has been made, which enabled the fabrication of various CNT devices for applications in electronics, biomedical techniques, and chemical/biological sensors. We have established a process to grow vertically...
