UC Santa Barbara Scientists Develop A Whole New Way of Harvesting Energy from the Sun

A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods. The researchers' findings are published in the latest issue of the journal Nature Nanotechnology.

Brookhaven Lab's National Synchrotron Light Source II Achieves LEED Gold Certification: Citation recognizes 'green' design, energy efficiency of Brookhaven's newest building

The National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy's Brookhaven National Laboratory has been awarded a LEED gold rating by the U.S. Green Building Council. NSLS-II is Brookhaven's newest building, and its half-mile ring building received the internationally recognized certification in recognition of its "green" design.

NASA's SDO Observes Fast-Growing Sunspot

728800main1_022013-continuum-304-670_0_0.jpg
The bottom two black spots on the sun, known as sunspots, appeared quickly over the course of Feb. 19-20, 2013. These two sunspots are part of the same system and are over six Earths across. This image combines images from two instruments on NASA's Solar Dynamics Observatory (SDO): the Helioseismic and Magnetic Imager (HMI), which takes pictures in visible light that show sunspots and the Advanced Imaging Assembly (AIA), which took an image in the 304 Angstrom wavelength showing the lower atmosphere of the sun, which is colorized in red.

NASA Deciphering the Mysterious Math of the Solar Wind

A constant stream of particles and electromagnetic waves streams from the sun toward Earth, which is surrounded by a protective bubble called the magnetosphere. A scientist at NASA Goddard has recently devised, for the first time, a set of equations that can help describe waves in the solar wind known as Alfven waves.

Titanium dioxide nanoreactor

Tiny particles of titanium dioxide are found as key ingredients in wall paints, sunscreens, and toothpaste; they act as reflectors of light or as abrasives. However with decreasing particle size and a corresponding change in their surface-to-volume ratio, their properties change so that crystalline titanium dioxide nanoparticles acquire catalytic ability: Activated by the UV component in sunlight, they break down toxins or catalyze other relevant reactions.

O2/Ar Ion Gun Spots the Difference

The Hiden IG20 high-brightness gas ion gun is further enhanced by the introduction of a new beam optic and ion source configuration to enable both increased beam brightness AND beam contrast, together with a significant reduction in ultimate spot size.
