Center for Nano-Optics Becomes Top-Level Georgia State University Research Center
The Center for Nano-Optics has been created at Georgia State University (Atlanta, Georgia), under the leadership of Georgia State Physics Professor Mark Stockman. The center will expand the university?s nanotechnology focus and continue the development of two university inventions ? the spaser, and the nanoplasmonic metal funnel.
The Center for Nano-Optics has been created at Georgia State University (Atlanta, Georgia), under the leadership of Georgia State Physics Professor Mark Stockman. The center will expand the university’s nanotechnology focus and continue the development of two university inventions – the spaser, and the nanoplasmonic metal funnel.
The spaser is a laser that is 1,000 times smaller than the smallest laser and also 1,000 times thinner than a human hair. Success in incorporating spaser technology into transistors, something that cannot be done now, may lead to computer processors that operate 100 to 1,000 times faster than today’s processors. Spasers may also help biomedical researchers identify and track single cancer cells in the bloodstream.
The second invention is the plasmonic metal funnel designed with a very thin needle at the end. This technology allows energy to be delivered to very small spaces. The funnel is already widely used in microscopes to give researchers the ability to see on the nanoscale.
The Big Review III: Molecular Vibration Theory
January 2nd 2025It has occurred to me that, in the 10+ years I have been writing about molecular vibrations, I have never introduced my readers to its basic theory! I will rectify that now. Some of this is new material, and some will be review. Either way, it is important that all this material be covered in one place.
Raman Microscopy for Characterizing Defects in SiC
January 2nd 2025Because there is a different Raman signature for each of the polymorphs as well as the contaminants, Raman microscopy is an ideal tool for analyzing the structure of these materials as well as identifying possible contaminants that would also interfere with performance.
ICP-MS Highlights: A Spectroscopy Year in Review
December 28th 2024Reflecting on 2024, the editors of Spectroscopy highlight some of the most notable articles and online content on inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled-optical emission spectroscopy (ICP-OES).
