Quantum dots enhance light-to-current conversion in layered semiconductors
Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).

Science
Climate models underestimate global warming by exaggerating cloud brightening
Researchers at Lawrence Livermore National Laboratory and Yale University have found that climate models are aggressively making clouds 'brighter' as the planet warms. This may be causing models to underestimate how much global warming will occur due to increasing carbon dioxide. The research appears in the April 8 edition of Science.

Plastic proteins: Synthetic material mimics essential characteristics of natural proteins
PNNL researchers hoping to design new materials for energy uses have developed a system to make synthetic polymers -- some would say plastics -- with the versatility of nature's own polymers, the ubiquitous proteins. Based on an inexpensive industrial chemical, these synthetic polymers might one day be used to create materials with functions as limitless as proteins, which are involved in every facet of life.

Existing state laws collectively require a 50 percent increase in US renewable electricity
State renewables portfolio standards, known as RPS policies, have contributed to more than half of all renewable electricity growth in the United States since 2000. Most state RPS requirements will continue to rise through at least 2020, if not beyond, and collectively these policies will require substantial further growth in US renewable electricity supplies. These findings are part of a new annual status report on state RPS policies from Berkeley Lab.

NREL raises rooftop photovoltaic technical potential estimate
Analysts at the Energy Department's National Renewable Energy Laboratory have used detailed light detection and ranging data for 128 cities nationwide, along with improved data analysis methods and simulation tools, to update its estimate of total US technical potential for rooftop photovoltaic systems. The analysis reveals a technical potential of 1,118 gigawatts of capacity and 1,432 terawatt-hours of annual energy generation, equivalent to 39 percent of the nation's electricity sales.

Insulator-superconductor transition of copper-oxide compound studied in fine detail
Using a highly controlled deposition technique, scientists from the US Department of Energy's (DOE) Brookhaven National Laboratory have synthesized ultrathin films containing multiple samples of a copper-oxide compound to study the compound's electronic behavior at near absolute zero, or minus 459 degrees Fahrenheit. Their study revealed that fluctuations in the distribution of electrical charges at near-absolute-zero temperature compete with superconductivity.

Scientists push valleytronics 1 step closer to reality
Berkeley Lab scientists have taken a big step toward the practical application of 'valleytronics,' which is a new type of electronics that could lead to faster and more efficient computer logic systems and data storage chips in next-generation devices. They experimentally demonstrated, for the first time, the ability to electrically generate and control valley electrons in a two-dimensional semiconductor.

Proving the genetic code's flexibility
Three-letter codons in a genome sequence can represent one of the 20 regularly used amino acids or stops. In the journal Angewandte Chemie International Ed., researchers from the US Department of Energy Joint Genome Institute and Yale University have discovered that microorganisms recognize more than one codon for selenocysteine. The finding adds credence to recent studies indicating that an organism's genetic vocabulary is not as constrained as had been long held.
