surface-plasmon resonance"

Surface Plasmons: Enhanced Nanoplasmonics
Optical gain in a dielectric compensates for absorption in metallic nanoparticles
Nature Photonics, published online October 5th, 2006
The compensation of loss in metal by gain in interfacing dielectric has been demonstrated in a mixture of aggregated silver nanoparticles and rhodamine 6G dye. An increase of the quality factor of surface plasmon (SP) resonance was evidenced by the six-fold enhancement of Rayleigh scattering. The compensation of plasmonic losses with gain enables a host of new applications for metallic nanostructures, including low- or no-loss negative-index metamaterials.

Activity Title: 2nd Annual Hands-On FutureTech Workshop
Description: 3 NSF Science and Technology Centers [STC-MDITR-University of Washington; CBST-UCDavis and CENS-UCLA] along with 2 NSF funded centers [NCN- Purdue, CCMR-Cornell and PREM-Photonic Metamaterials-NSU] showcased several exciting research topics at the 2nd Annual Hands-On FutureTech Workshop hosted by the Center for Materials Research at Norfolk State University. With an attendance exceeding 120 participants, from many minority serving institutions, underrepresented minority students were able to meet with peers, staff and faculty and interactively discover leading edge science and technology research at participating centers. This initiative will help in drawing more minority students to STEM disciplines and encourage them to pursue graduate studies at participating centers.
Date: November 17, 2006
Audience Description: African American, Hispanic, Native American students
Approx. Number of Attendees: 120
