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.

Mapping a path to improved cassava production
Though cassava is easy to cultivate, it is particularly vulnerable to plant pathogens, which can significantly reduce crop yields. To help improve breeding strategies for this root crop, a team led by UC Berkeley and DOE JGI researchers have described cassava's genetic diversity in the journal Nature Biotechnology. With the help of genomics, researchers hope to apply advanced breeding strategies that can improve cassava's resistance to diseases and improve crop yields.

'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.

Elusive state of superconducting matter discovered after 50 years
Scientists at the US Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964 -- a 'Cooper pair density wave.' The discovery, described in a paper published online April 13, 2016, in Nature, may provide key insights into the workings of high-temperature superconductors.

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.
