Tue 19 Apr 2016. New Perovskite-Silicon Tandem Solar Cell Efficiency Record of 25.5%. Scientists used the novel solar material to create a hybrid solar cell with an efficiency of 25.5 percent – the highest level ever recorded. As recently as 2009, perovskite solar cells barely delivered efficiencies above 4 percent. The researchers used a three-tiered approach in creating their hybrid solar cell. The top layer, consisting of light-absorbing perovskite, captures short wavelength photons, while a bottom layer coated with silicon harvests longer wavelength photons. More

Mon 18 Apr 2016. A new chemical method to clean contaminated groundwater. Researchers ran a series of experiments in a laboratory setting using water containing uranium — present in contaminated groundwater at various sites in the United States as a legacy of Cold War-era processing and waste disposal activities associated with nuclear materials production. Calcium and phosphate work together chemically to immobilize uranium, which is shown to lead to increased cancer risk and liver damage in humans when ingested. More

Wed 13 Apr 2016. Light and sound waves used to control electron states. Physicists have combined light and sound to control electron states in an atom-like system, providing a new tool in efforts to move toward quantum-computing systems. New research was done on diamond topped with a layer of zinc oxide containing electrical conductors and performed at a temperature of 8 degrees Kelvin, just above absolute zero. The research focused on a goal of quantum-computing research—taking advantage of defects in diamond known as nitrogen vacancy centers, where a nitrogen atom substitutes for a carbon atom adjacent to a missing carbon atom. These defects are, in effect, artificial atoms that can be used as qubits. More

Mon 21 Mar 2016. Air Data Can Be Used to Reconstruct Radiological Releases. New research demonstrates that experts can use data from air sampling technology to not only detect radiological releases, but to accurately quantify the magnitude and source of the release. This has applications for nuclear plant safety, nuclear security, and nuclear nonproliferation monitoring. More
