Cold-Atom Lab in a Box
Jul 1, 2011 — Bringing cold atoms to the classroom gives undergraduate students a hands-on way to learn about physics – and could inspire lifetime careers using photonics to manipulate atoms. Bringing cutting-edge physics into the undergraduate classroom is not always easy. “Cold atoms” (<0.0003 K) were first produced in the late 1980s, but creating the right conditions for them still requires research specialists in advanced physics laboratories. Re-creating the original experiment...
Potomac Photonics to Host Inaugural LIA Chapter Mtg

New Metamaterials Center to Focus on Solar Energy, Sensors
NEW YORK, April 15, 2011 — A new industry and university cooperative research center proposes to provide a one-stop shop for the design, fabrication and testing of a wide range of metamaterials designed to aid solar photovoltaic systems, specialized light sensors and more. ...
TPV Researcher Wins NSF Early-Career Award
MEDFORD/SOMERVILLE, Mass., April 15, 2011 — Tom Vandervelde, assistant professor of electrical and computer engineering at Tufts University, has been given an early-career award from the National Science Foundation for promising research in thermophotovoltaics (TPVs). Vandervelde, the...
US, UK Fund Photosynthesis Improvements
ARLINGTON, Va., April 4, 2011 — Scientists in the US and the UK have been awarded funding totaling more than $10.3 million to improve the process of biological photosynthesis. The US National Science Foundation (NSF) and the UK Biotechnology and Biological Sciences Research...
Organic phosphors glow in jewel tones
ANN ARBOR, Mich. – A new class of pure organic compounds that glow in jewel tones could lead to cheaper, more efficient and more flexible display screens, among other applications. Researchers at the University of Michigan developed a class of material that shines...
BU, UC Davis Launch Biophotonics Center
BOSTON, March 23, 2011 — A new research collaboration will be formed by Boston University and the University of California, Davis, under a grant from the National Science Foundation that fosters university-industry collaboration. The new Center for Biophotonic Sensors and...
Ultrafast Laser Scribing Cuts Cost, Hikes Solar Cell Efficiency
WEST LAFAYETTE, Ind., March 17, 2011 — An advancement that will improve solar cell efficiency and reduce manufacturing costs involves using an ultrafast pulsed laser scribing technique to create more precise microchannels. Microchannels are critical to cost and efficiency because...
Jewel-toned Organic Phosphorescent Crystals
ANN ARBOR, Mich., Feb. 15, 2011 — A new class of pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications. University of Michigan researcher Jinsang Kim and his colleagues have developed...
‘C Dots’ Head to Clinical Trial
ITHACA, N.Y., Feb. 2, 2011 — “Cornell Dots” — brightly glowing nanoparticles — may soon be used to illuminate cancer cells to aid in diagnosis and treatment. The FDA has approved the new technology for the first clinical trial in humans. It is the first...
Smart Lasers Could Make Biopsies Painless
EAST LANSING, Mich., Feb., 2, 2011 — Biopsies in the future may be painless and noninvasive, thanks to smart laser technology being developed at Michigan State University. To test for skin cancer, patients today must endure doctors cutting away a sliver of skin, sending the...
Laser-treated Parchment Creates Microfluidic Device
WEST LAFAYETTE, Ind., Jan. 26, 2011 — Using lasers to create patterns on common parchment paper, researchers are now able to make "microfluidic" devices for rapid medical diagnostics and chemical analysis. The innovation represents a way to enhance commercially available diagnostic...
Imaging Between a Rock and a Hard Tooth
EVANSTON, Ill., Jan. 20, 2011 — Here’s something to chew on: An imaging technique sensitive enough to be used at the atomic scale has been used for the first time to create 3-D maps of the teeth of chitons – a class of marine mollusks that can literally chew rock...
Carbon Nanotubes As Optical Antennae
ITHACA, N.Y., Jan. 6, 2011 — Just as walkie-talkies transmit and receive radio waves, carbon nanotubes can transmit and receive light at the nanoscale, Cornell University researchers have discovered. Carbon nanotubes, cylindrical rolled-up sheets of carbon atoms, might...
