MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
out of 5 stars
25 Feb 2008 | | Contributor(s):: Bhaskaran Muralidharan, owen miller, Neeti Kapur, Avik Ghosh, Supriyo Datta
We first outline the qualitatively different physics involved in the charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting) self-consistent field (SCF) and the weakly coupled (strongly interacting) Coulomb Blockade (CB) regimes. The CB...
What Promises do Nanotubes and Nanowires Hold for Future Nanoelectronics Applications?
18 Feb 2008 | | Contributor(s):: Joerg Appenzeller
Various low-dimensional materials are currently explored for future electronics applications. The common ground for all these structures is that the surface related impact can no longer be ignored – the common approach applied to predict properties of bulk-type three-dimensional (3D) materials....
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....
SPMW Scanning Probe Acceleration Microscopy: Towards Real Time Reconstruction of Tip-Sample Forces in Tapping Mode AFM
05 Jan 2007 | | Contributor(s):: Tomasz Kowalewski
Tapping mode atomic force microscopy (TMAFM) in fluids has become an increasingly important technique, especially in studying biological samples under near physiological conditions. However, until recently the physics of tapping mode operation under fluids has not been well understood. The first...
Combining New Experimental and Informatic Tools for Protein Investigation and Engineering
09 Jan 2008 | | Contributor(s):: Alan Friedman
The stability and activity of proteins is dependent on both the correct functioning and placement of individual amino acids and their interactions. Great attention has been paid to critical individual residues (generally revealed by their location in the active site and their conservation among...
SPMW Single molecule recognition atomic force microscopy
05 Jan 2007 |
In molecular recognition force microscopy (MRFM), ligands are covalently attached to atomic force microscopy tips for the molecular recognition of their cognitive receptors on probe surfaces. A ligand-containing tip is approached towards the receptors on the probe surface, which possibly leads...
SPMW Scanning Impedance Microscopy: probing local electronic structure and transport anomalies
05 Jan 2007 | | Contributor(s):: dawn bonnell
Multiple modulation SPM is a general term for a strategy that extracts information about a surface or nanostructure by combining various signals on samples and tips, using multiple frequencies to distinguish them and accessing multiple harmonics in detection. In addition to the usual...
Nanomedicine for Treating Organ Failure
02 Jan 2008 |
Nanotechnology has begun to revolutionize numerous science and engineering fields. The use of nanotechnology in medicine has been termed nanomedicine. This presentation will highlight recent advancements in the treating of organ failures (such as orthopedic, vascular, cartilage, central and...

Excellence in Computer Simulation
19 Dec 2007 | | Contributor(s):: Mark Lundstrom, Jeffrey B. Neaton, Jeffrey C Grossman
Computational science is frequently labeled as a third branch of science - equal in standing with theory and experiment, and computational engineering is now an essential component of technology development and manufacturing. The successes of computational science and engineering (CSE) over the...
Hierarchical Temporal Memory: How a New Theory of Neocortex May Lead to Truly Intelligent Machines
12 Dec 2007 | | Contributor(s):: Jeff Hawkins
Coaxing computers to perorm basic acts of perception and robotics, let alone high-level thought, has been difficult. No existing computer can recognize pictures, understand language, or navigate through a cluttered room with anywhere near a child's facility. Following nature's example, Jeff...
KIST/PU Infrared and Raman Chemical Imaging of Pharmaceutical Biological Matter
06 Dec 2007 | | Contributor(s):: Tom Tague
There have been several advances in instrumentation that now facilitate infrared and Raman imaging. Current Focal-Plane-Array (FPA) detectors are very robust and read out quickly for infrared imaging and fast CCD array detectors are now available for Raman imaging. For example, infrared data...
KIST/PU Ligand-functionalized gold nanorods as theragnostic agents
06 Dec 2007 | | Contributor(s):: Alexander Wei
Plasmon-resonant gold nanorods have been examined as multifunctional agents for imaging and photoactivated therapies. Nanorods can be imaged with single-particle sensitivity by two-photon luminescence (TPL) when excited by fs-pulsed laser irradiation, and have been monitored in vivo while...
