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 ...
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 ...
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 ...
University of Wyoming uses NTA to characterize nanoparticles in natural environments
15-05-2013
NanoSight reports on how Nanoparticle Tracking Analysis, NTA, is being used at the University of Wyoming in the characterization of the physical and interfacial properties of manufactured nano materials. Dr Jonathan Brant is leader of the group, "Interfaces in the Environment: membranes, ...
Scientists use crowd-sourcing to help map global CO2 emissions
Researchers launch environmental 'game' for citizen scientists
14-05-2013
Climate science researchers from Arizona State University are launching a first-of-its kind online "game" to better understand the sources of global warming gases. By engaging "citizen scientists," the researchers hope to locate all the power plants around the world and quantify their carbon ...
Group of Bradford Co, Pa. residents concerned about health effects of hydrofracking
13-05-2013
Residents living in areas near natural gas operations, also known as hydraulic fracturing, or fracking, are concerned their illnesses may be a result of nearby drilling operations. Twenty-two percent of the participants in a small pilot study surmise that hydrofracking may be the cause of ...
HX-splitting photocatalysis for solar fuels
07-05-2013
Photochemical HX splitting reactions (X = halogen) provide a route for solar-to-fuel energy conversion and halogen photoelimination is a critical step in the process. Scientists in the US have investigated the photoreduction mechanism of a pair of valence-isomeric dirhodium phosphazane ...
