Computing the Horribleness of Soft Condensed Matter
19 Oct 2007 | | Contributor(s):: Eric Jakobsson
A great triumph of computer simulations 40 years ago was to make the liquid state of matter understandable in terms of physical interactions between individual molecules. Prior to the first simulations of liquid argon and liquid water in the 1960's, there was no quantitatively rigorous molecular...

Conquering Surface Plasmon Resonance Loss in Metallic Nanostructures
16 Oct 2007 | | Contributor(s):: Mikhail A. Noginov
We have observed the compensation of loss in metal by gain indielectric in the mixture of Ag aggregate and rhodamine 6G dye. Thedemonstrated six-fold enhancement of the Rayleigh scattering is the evidence of the enhancement of the localized surface plasmon (SP) resonance. In the attenuated total...

Construction of an Imitating Nano-motor Driven by Six ATP-binding RNAs of Bacterial Virus phi29
02 Dec 2004 | | Contributor(s):: Peixuan Guo
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...

Control of Exchange Interaction in a Double Dot System
05 Feb 2004 | | Contributor(s):: Mike Stopa
As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum...

Control of Spin Precession in a Datta-Das Transistor Structure
19 Dec 2009 | | Contributor(s):: Hyun Cheol Koo
Transistors Switch onto Spin Using the spin of an electron in addition to, or instead of, the charge properties is believed to have many benefits in terms of speed, power-cost, and integration density over conventional electronic circuits. At the heart of the field of spintronics has been a...

Creating Research Links between Science at the Nanoscale and Science Education
28 Feb 2006 | | Contributor(s):: Nora H. Sabelli
This talk will address what is needed to reduce the gap between current science education and science education that incorporates the ideas in current nanoscience. The ability to manipulate matter at increasingly smaller scales of distance and time has blurred the boundaries between disciplines....

DNA Charge Motion: Regimes and Behaviors
28 Jul 2005 | | Contributor(s):: Mark Ratner
Because DNA is a quasi-one-dimensional species, and because each base is a pi-type chromphore, it was long ago suggested that DNA could conduct electricity. This has become a widely investigated area, and remains of interest for fundamental science and for applications. We will discuss a very...
