Cleaning up hybrid battery electrodes improves capacity and lifespan
Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with a gentle-sounding way of making electrodes. Called ion soft-landing, the high-precision technique resulted in electrodes that could store a third more energy and had twice the lifespan compared to those prepared by a conventional method, the researchers report in Nature Communications.

Advances in extracting uranium from seawater announced in special issue
The oceans hold more than four billion tons of uranium--enough to meet global energy needs for the next 10,000 years if only we could capture the element from seawater to fuel nuclear power plants. Major advances in this area have been published by the American Chemical Society's journal Industrial & Engineering Chemistry Research. Oak Ridge National Laboratory and Pacific Northwest National Laboratory led more than half of the 30 papers in the special issue.

Science Advances
'Odd couple' monolayer semiconductors align to advance optoelectronics
In a study led by Oak Ridge National Laboratory, scientists synthesized a stack of atomically thin monolayers of two lattice-mismatched semiconductors. Where the two semiconductor layers met, they formed an atomically sharp heterostructure, which generated a photovoltaic response by separating electron-hole pairs that were generated by light. The achievement of creating this atomically thin solar cell shows the promise of synthesizing mismatched layers to enable new families of functional two-dimensional materials.

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.

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.
