ORNL researchers probe chemistry, topography and mechanics with one instrument
ORNL scientists combined atomic force microscopy and mass spectrometry into one instrument that can probe a polymer sample in three dimensions and overlay information about the topography of its surface, the atomic-scale mechanical behavior of the bulk sample, and subsurface chemistry. Their results are published in ACS Nano.

Counting all costs, Berkeley Lab researchers find that saving energy is still cheap
Researchers at Berkeley Lab have conducted the most comprehensive study yet of the full cost of saving electricity by US utility efficiency programs and now have an answer: 4.6 cents. That's the average total cost of saving a kilowatt-hour in 20 states from 2009 to 2013.

Scientists use nanoscale building blocks and DNA 'glue' to shape 3-D superlattices
Taking child's play with building blocks to a whole new level-the nanometer scale-scientists at the US Department of Energy's Brookhaven National Laboratory have constructed 3-D 'superlattice' multicomponent nanoparticle arrays where the arrangement of particles is driven by the shape of the tiny building blocks. The method uses linker molecules made of complementary strands of DNA to overcome the blocks' tendency to pack together in a way that would separate differently shaped components.

Erupting electrodes: How recharging leaves behind microscopic debris inside batteries
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body, and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries in work appearing in the March issue of the journal Nano Letters.

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2015
By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.

Genome Research
Longer DNA fragments reveal rare species diversity
A challenge in metagenomics is that the more commonly used sequencing machines generate data in short lengths, while short-read assemblers may not be able to distinguish among multiple occurrences of the same or similar sequences, making it difficult to identify all the members in a microbial community. In the April 2015 issue of Genome Research, a team including DOE JGI researchers compared two ways of using next generation Illumina sequencing machines to help with this.

Goodbye, range anxiety? Electric vehicles may be more useful than previously thought
In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles will meet the daily travel needs of drivers longer than commonly assumed. They found that batteries that have lost 20 percent of their originally rated energy storage capacity can still meet the daily travel needs of more than 85 percent of US drivers.

ORNL-led team demonstrates desalination with nanoporous graphene membrane
Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

Sandia showcases biology breakthroughs available for licensing
Technologies developed in Sandia National Laboratories' biosciences program could soon find their way into doctors' offices -- devices like wearable microneedles that continuously analyze electrolyte levels and a lab-on-a-disk that can test a drop of blood for 64 different diseases in minutes. At a recent seminar for potential investors and licensees, part of the Sandia Technology Showcase series, Sandia bioscientists presented eight ready-to-license technologies in three key areas: medical diagnostics, biosurveillance and therapeutics and drug discovery.

Iron rain fell on early Earth, new Z machine data supports
Physical tests at Sandia's Z machine reveal that, at pressures rivaling those when worlds collide, iron vaporizes at far lower pressures than assumed by theoreticians, explaining why the element is distributed in Earth's mantle rather than collected at its core.

A better way of scrubbing CO2
Berkeley Lab researchers have discovered a means by which the removal of carbon dioxide (CO2) from coal-fired power plants might one day be done far more efficiently and at far lower costs than today. By appending a diamine molecule to the sponge-like solid materials known as metal-organic-frameworks (MOFs), the researchers were able to more than triple the CO2-scrubbing capacity of the MOFs, while significantly reducing parasitic energy.
