A new laser paradigm: An electrically injected polariton laser
17-05-2013
Engineering researchers at the University of Michigan have demonstrated a paradigm-shifting "polariton" laser that's fueled not by light, but by electricity. Polaritons are particles that are part light, and part matter. "We report the first electrically injected polariton laser—a truly ...
UC Santa Barbara scientist studies methane levels in cross-continent drive
17-05-2013
After taking a rented camper outfitted with special equipment to measure methane on a cross-continent drive, a UC Santa Barbara scientist has found that methane emissions across large parts of the U.S. are higher than currently known, confirming what other more local studies have found. Their ...
Never-before-seen energy pattern observed at National High Magnetic Field Laboratory
Multiple publications based on research conducted at MagLab
17-05-2013
Two research teams at the National High Magnetic Field Laboratory (MagLab) broke through a nearly 40-year barrier recently when they observed a never-before-seen energy pattern. The butterfly-shaped pattern was first theorized by physicist Douglas Hofstadter in 1976, but it took the tools and ...
Stanford ultraresponsive magnetic nanoscavengers for next generation water purification
New synthetic cored nanoparticle could decontaminate tainted water and then be cleared with a magnet
17-05-2013
Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using ...
Bacterium counteracts coffee ring effect
16-05-2013
Ever notice how a dried coffee stain has a thicker outer rim, while the middle of the stain remains almost unsoiled? This 'coffee ring effect' also occurs in other materials. Researchers from the Departments of Chemical Engineering and Chemistry at KU Leuven have now discovered how to ...
The drones of oil
Geologists in Norway are using flying drones with cameras to hunt for oil
16-05-2013
Geologists have long used seismology on the bottom of the ocean or have been throwing dynamite from snowmobiles when they look for oil. But now researchers at Centre for integrated petroleum research (CIPR), a joint venture between the University of Bergen (UiB) and Uni Research, have found a ...
Keeping fruit, vegetables and cut flowers fresh longer
16-05-2013
New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers — a gas whose effects are familiar to everyone who has seen bananas and other fruit ripen too quickly and rot. That's the ...
Graphene joins the race to redefine the ampere
15-05-2013
A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron pump (SEP), described in a paper in Nature Nanotechnology, ...
Nano-breakthrough: Solving the case of the herringbone crystal
15-05-2013
Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To find out, they turned to experts in computer simulation at the University of Michigan ...
Environmental significance of chiral persistent organic pollutants
15-05-2013
Enantioselectivity has been recognized in the fields of life science, pharmacology, modern medicine, and chemistry. The increasing release of chiral persistent organic pollutants (POPs) into the environment in recent decades has led to an increase in scientific research into their ...
