Stanford University News
Solar Process Gives Oil a Run for its Money
STANFORD, Calif., Aug. 23, 2010 — Stanford engineers have figured out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as efficient as existing methods and potentially cheap enough to compete with oil. Unlike photovoltaic technology currently used in solar panels — which becomes less efficient as the temperature rises — the new process excels at higher temperatures. Called 'photon enhanced thermionic emission,'...
Superpowerful X-ray Laser Dedicated
MENLO PARK, Calif., Aug. 17, 2010 — The Linac Coherent Light Source, (LCLS), the first and most powerful x-ray laser, was officially dedicated Monday at SLAC National Accelerator Laboratory by Energy Secretary Steven Chu. The $420 million LCLS is a new type of scientific facility that...
EMCCD camera redraws the boundaries of superresolution 3-D imaging
BELFAST, UK – Researchers in the US have developed a superresolution 3-D imaging technique that resolves single fluorescent molecules with >10 times the precision of conventional optical microscopy. Using an iXon+ electron multiplying CCD (EMCCD) camera from...
Monster Technology — The ‘Frankencamera’
STANFORD, Calif., July 29, 2010 — It’s big and it ain’t pretty, but it’s an experimentation in computation photography that went so right. It’s a new programmable camera platform called “Frankencamera.” A Stanford University photography...
Biolase Appoints New Board Members
IRVINE, Calif., July 21, 2010 — Dental laser maker Biolase Technology Inc. has announced the appointment of two veterans of business, finance and medicine to its board of directors. Dr. Alex Arrow and Dr. Norman J. Nemoy will join the board effective immediately, replacing George...
LIA: Becoming the Laser Institute of America
Jul 1, 2010 — As just about everyone knows, American physicist Theodore Maiman fired the first laser in May 1960 in Malibu, Calif. What is less well-known is that, in February 1968, also in California, Maiman and other laser pioneers founded the Laser Industry...
Cambridge NanoTech Partners with Stanford
CAMBRIDGE, Mass., June 21, 2010 — Atomic layer deposition (ALD) science and equipment provider, Cambridge NanoTech, announced Tuesday its partnership with Stanford University’s Center for Integrated Systems (CIS), a partnership between academia and industry that supports...
Terahertz Sensors Improve Optics
ARLINGTON, Va., June 14, 2010 — Air Force Office of Scientific Research-funded Professors Mark L. Brongersma of Stanford University and Stefan A. Maier of Imperial College London are investigating new applications for terahertz sensors. Based on their research, these sensors...
Chiral Gold Nanocluster Demystified
JYVÄSKYLÄ, Finland, June 1, 2010 — After ten years, the mystery of the structural, electronic and optical properties of a chiral gold nanocluster, has finally been resolved. Researchers at the Department of Chemistry and Nanoscience Center (NSC) of the University of...
EMCCD Resets Limit of 3-D Imaging
BELFAST, Northern Ireland, May 24, 2010 — With the help of a highly sensitive Andor iXon+ electron-multiplying CCD camera, US researchers have developed a super-resolution, 3-D imaging technique that can resolve single fluorescent molecules with greater than 10 times more precision than...
SDO Unveils Images of ‘First Light’
PALO ALTO, Calif., April 23, 2010 — Spectacular “first light” images and data from three state-of-the art instruments on NASA’s Solar Dynamics Observatory (SDO) were unveiled this week. The SDO spacecraft was launched aboard a United Launch Alliance Atlas V rocket...
Dark Matter Measures Age of Universe
DAVIS, Calif., March 23, 2010 — Astronomers from the United States and Europe have used a gravitational lens – a distant, light-bending clump of dark matter – to make a new estimate of the Hubble constant, which determines the size and age of the universe. The Hubble constant...
Ross to Lead US-Scotland Photonics Project
GLASGOW, Scotland, March 23, 2010 – Iain Ross was named director at SU2P, a £2.4 million initiative between universities in Scotland and California which will enhance the economic impact of their research in photonic...
Restoring vision with photovoltaic optoelectronics
Mar 18, 2010 — As life expectancy increases, our eyes bear the brunt of aging; many of the elderly suffer from vision problems. One of the leading causes of eye problems in the Western world is macular degeneration. To correct this, retinal implants, generally...
The art of microspectroscopy
Feb 28, 2010 — Martin noted that both spectra and high-resolution digital images can be acquired with the company’s microspectrophotometers, also known as microspectrometers (including its QDI 2010 model), which are designed to measure the UV-VIS-NIR spectra of...
Atom Interferometer Tests Redshift
BERKELEY, Calif., Feb. 19, 2010 - While airplane and rocket experiments have proved that gravity makes clocks tick more slowly – a central prediction of Albert Einstein’s general theory of relativity – a new experiment in an atom interferometer measures this slowdown 10,000 times...
Glaring at the Sun with NASA’s SDO
CAPE CANAVERAL, Fla., Feb. 11, 2010 – At approximately 10:30 Eastern today, NASA launched its Solar Dynamics Observatory (SDO), the first of the space agency’s “Living with a Star” programs to blast-off. The programs are intended to study and understand the causes of solar variability...
Photon Race Ends in Dead Heat
STANFORD, Calif., Oct. 29, 2009 – Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA’s orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among...
Revolutionizing Spintronics
MENLO PARK, Calif., June 16, 2009 – Physicists at the Department of Energy's (DoE) SLAC National Accelerator Laboratory and Stanford University have now confirmed that there is an exotic type of material that could one day provide dramatically faster, more efficient computer chips.
World's Smallest Nanoletters
STANFORD, Calif., Feb. 2, 2009 – Stanford researchers have reclaimed bragging rights for creating the world’s smallest writing, a distinction the university first gained in 1985 and lost in 1990. The letters in the words are assembled from subatomic-size bits as small as 0.3 nm,...
3-D MRI Extends to Nanoscale
SAN JOSE, Calif., Jan. 13, 2009 – The creation of a microscopy tool with ultrahigh resolution, combined with an advanced 3-D image reconstruction technique, has enabled scientists to demonstate magnetic resonance imaging (MRI) on biological objects such as viruses. The achievement...
Nanoparticles as Beacons
STANFORD, Calif., April 1, 2008 -- Raman spectroscopy has been used to take images deep within the human body, after injecting tiny nanoparticles to serve as beacons. The method is expanding the available tools for molecular imaging, enabling illumination of tumors in living subjects...
What Can You See in 10–18 Seconds?
Oct 1, 2007 — Most scientific endeavors seek to add to the collective understanding of a topic, whether it is the origin of a disease, the basis of human communication or the techniques that will improve the performance of an athlete, of a dairy cow or of a...
Polariton Propagation Probed
PROVIDENCE, R.I., July 18, 2007 -- An experiment modeled on the classic “Young’s double-slit experiment" has powerfully reinforced the understanding that surface plasmon polaritons (SPPs) propagate and diffract just like any other wave. The demonstration is a reminder that...
We Forget to Remember
STANFORD, Calif., June 7, 2007 -- The brain's ability to suppress irrelevant memories makes it easier for humans to remember what's really important. "Any act of remembering reweights memories, tweaking them to try to be more adaptive for the next time you try to remember...
