Nearly Dissipationless Current Achieved Through Light-Induced Switch
AMES, Iowa, Jan. 21, 2021 — Researchers at the U.S. Department of Energy’s Ames Laboratory, along with collaborators from Brookhaven National Laboratory and the University of Alabama at Birmingham, have found a light-induced switch that twists the crystal lattice of the material and switches on an electron current that appears to be nearly dissipationless. The discovery was made in a class of topological materials that researchers believe holds great promise for spintronics, topological effect transistors, and
LaserNetUS Awarded $18M by US DOE
WASHINGTON, D.C., Oct. 28, 2020 — The U.S. Department of Energy announced $18 million in funding for LaserNetUS, a network of 10 high-intensity laser facilities at national laboratories and universities in the United States and Canada. The initiative, established in 2018, is...
Report: Solar Panels from China Not So Green
EVANSTON, Ill., and LEMONT, Ill., May 30, 2014 — With fewer environmental standards for factories and more electricity generated from non-renewable sources, China’s carbon footprint is about twice as large as Europe’s. This makes China’s manufacturing of energy-saving tools, such...
New Thin-film Transistors Could Mean Flexible Screens
ARGONNE, Ill., May 29, 2014 — Ultra-thin, flexible transistors could lead to the next generation of screens for computers, smartphones and televisions. A team from the U.S. Department of Energy’s Argonne National Lab has created transparent transistors 10 atomic layers...
Nanoscope Can Probe Chemistry on the Molecular Scale
BERKELEY, Calif., and BOULDER, Colo., May 9, 2014 — The in-depth study of complex molecular systems, from batteries and electronic materials to living cells and even stardust, is now possible with a new imaging technique. Broadband IR synchrotron light has enabled researchers at Lawrence Berkeley...
Exciton Movement Observed Directly
CAMBRIDGE, Mass., and NEW YORK, April 17, 2014 — For decades, scientists' understanding of excitons has been theoretical at best. However, a recent breakthrough has changed the game.
Solar Cells Get Boost from Quantum Dots
LOS ALAMOS, N.M. and MILAN, April 15, 2014 — Quantum dots may have a bright future in solar energy. Researchers from Los Alamos National Laboratory, in collaboration with the University of Milan-Bicocca, have found that the superior light-emitting properties of quantum dots can efficiently...
Nanostructures Show Promise for Efficient LEDs
ANN ARBOR, Mich., April 8, 2014 — Nanostructures and an indium nitride (InN) semiconductor could hold promise for improving the efficiency of LEDs, particularly in the green gap, where productivity typically takes a dive. Researchers from the University of Michigan conducted tests...
System Pushes Better Light Control
CAMBRIDGE, Mass., March 27, 2014 — More precise control of light could be on the horizon, prompting advances in solar photovoltaics, detectors for telescopes and microscopes, and privacy filters for display screens.
Ultrabright Nanocrystals Could Image Single Proteins
BERKELEY, Calif., March 19, 2014 — The future is bright in the world of biological imaging with the recent creation of ultrabright, ultrasmall light-emitting crystals that can image single proteins.
For phasing nanocrystals, size really matters
BERKELEY, Calif. – Size is of much greater importance than previously believed in metal nanocrystals undergoing phase transformations, a finding that has important implications for the future design of hydrogen storage systems, catalysts, fuel cells and batteries....
Have Faith and Go for It
Oct 1, 2013 — ‘There is never a good reason to not try; there is never a certainty of failure. Having your own business is far less risky than being an employee.’ – Mike Morris, founder of Ocean Optics Inc. and Spectrecology Mike Morris founded...
For Phasing Nanocrystals, Size Really Matters
BERKELEY, Calif., Aug. 27, 2013 — Size is of much greater importance than previously believed in metal nanocrystals undergoing phase transformations, a finding that has important implications for the future design of hydrogen storage systems, catalysts, fuel cells and batteries.
IR Tomography Goes Full Color
BERKELEY, Calif., Aug. 6, 2013 — Combining Fourier transform infrared (FTIR) spectroscopy with computed tomography creates a non-destructive, 3-D imaging technique providing full-color, molecular-level chemical information of unprecedented detail on biological and other samples...
The car of the future will be here soon. You just don’t know it yet.
May 14, 2013 — The future can be sly. We expect to wake up one day and suddenly have jetpacks and sentient robots trying to kill us. But as often as not the technology of the future comes at us slowly, incrementally. So it’s no great surprise when it finally...
3 Questions Interview
Apr 1, 2013 — Director of R&D at ITT Exelis Geospatial Systems in Rochester, N.Y., Dr. Robert D. Fiete has been elected a 2013 SPIE Fellow. He created the imaging chain model for Ikonos, the first commercial high-resolution imaging satellite. He also helped...
X-Ray Laser Observes Photosynthesis in Action
MENLO PARK, Calif., Feb. 20, 2013 — The structure and chemical behaviors of a natural catalyst involved in photosynthesis were observed simultaneously for the first time, using an x-ray laser. The discovery opens a new window on the way plants generate the oxygen we breathe.
Defying expectations, x-ray laser supercharges atoms
MENLO PARK, Calif. – Using a single flash from the world’s most powerful x-ray laser, researchers have stripped a record number of electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low....
Multijunction Solar Cell Design Could Exceed 50% Efficiency
WASHINGTON, Jan. 15, 2013 — A lattice-matched, triple-junction solar cell proposed by an international team of scientists has the potential to break the 50 percent conversion efficiency mark, a goal in multijunction photovoltaic development.
Universal Display Nabs DoE Grant for White OLEDs
EWING, N.J., Dec. 3, 2012 — Universal Display Corp. will develop cost-effective outcoupling enhancement for energy-efficient, thin-form-factor white organic LED lighting panels under a US Department of Energy (DoE) grant. The outcoupling techniques — which increase the...
NRC licenses laser enrichment facility
Dec 1, 2012 — A first-of-its-kind facility for the laser enrichment of uranium has received a license from the US Nuclear Regulatory Commission. The license authorizes GE Hitachi Nuclear Energy’s Global Laser Enrichment (GLE) to enrich uranium up to 8...
X-ray Laser Helps Fight Sleeping Sickness
MENLO PARK, Calif., Nov. 29, 2012 — A weak spot in the parasite that causes African sleeping sickness, a disease that kills an estimated 30,000 people each year, has been mapped using an x-ray laser, pinpointing a promising new target for treating the fly-borne illness.
