Researchers from the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the University of California at Berkeley, and the Vavilov State Optical Institute in St. Petersburg, Russia, have now made sensitive measurements of magnetic fields by maintaining the spin polarization of atoms in an alkali-vapor magnetometer for more than 60 seconds at room temperature - a two-orders-of-magnitude improvement in this important measurement parameter over the best previous performance.
As industries and consumers increasingly seek improved battery power sources, cutting-edge microscopy performed at the Department of Energy's Oak Ridge National Laboratory is providing an unprecedented perspective on how lithium-ion batteries function.
A new genre of construction materials, made with particles barely 1/50,000th the width of a human hair, is about to play a big role in the building of homes, offices, bridges, and other structures, according to the latest episode in the American Chemical Society's award-winning podcast series, 'Global Challenges/Chemistry Solutions'.
New research uses fluorescence correlation spectroscopy (FCS) to investigate the processes at the surface of a growing crystal. By focusing a laser on the crystal surface and measuring the resulting fluorescence, FCS can resolve dimensions as small as a single wavelength of the light.
Delft University of Technology officially opens a new Department of Bionanoscience on Thursday 16 September. The new department will focus on virtually unexplored scientific terrain: the interface between biology and nanoscience.
Researchers from Europe and China warn that little can be done to stop dangerous increases in the global sea level, as it will rise between 30 to 70 centimetres (cm) by 2100 even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and stringently control greenhouse gas emissions.
To highlight breakthroughs in this area, the editors of Energy Express, a bi-monthly supplement to Optics Express, the open-access journal of the Optical Society, today published a special Focus Issue on thin-film photovoltaic materials and devices.
An international all-star lineup of experts in solar and biofuel energy, climate science, urban design and other areas of research critical to sustainable energy technologies will gather in Berkeley for a public symposium on October 1 and 2, 2010.
The light, tickling tread of a pesky fly landing on your face may strike most of us as one of the most aggravating of life's small annoyances. But for scientists working to develop pressure sensors for artificial skin for use on prosthetic limbs or robots, skin sensitive enough to feel the tickle of fly feet would be a huge advance. Now Stanford researchers have built such a sensor.
