MCW07 Impact of Porphyrin Functional Groups on InAs Gas Sensors
out of 5 stars
05 Nov 2007 | | Contributor(s):: Michael Garcia
Porphyrin molecules are often used for sensor engineering to improve sensitivity and selectivity to specific analytes. It is important to understand how the porphyrin HOMO-LUMO levels deplete surface states during functionalization of solid state sensors. Additionally, the effect of...

23 Oct 2007 | | Contributor(s):: Kui Won Choi
The Global Research Laboratory (GRL) program was initiated by the Korea Foundation for International Cooperation of Science and Technology (KICOS) in 2006. The GRL program has been designed to develop fundamental and original technologies through international collaborative research between...
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...
