Computational design of patterned interfaces using reduced order models

We develop and validate a computational strategy for designing interfaces with controlled misfit dislocation patterns by tailoring interface crystallography and composition.

Longitudinal analysis of microbial interaction between humans and the indoor environment

The bacteria that colonize humans and our built environments have the potential to influence our health. Microbial communities associated with seven families and their homes over 6 weeks were assessed, including three families that moved their home.

Breaking down differences in modeling soil water substantially shifts carbon stored in land

A team led by researchers at Pacific Northwest National Laboratory modeled runoff, that is, water's movement over the land surface and through the subsurface, using two widely adopted methods. They found that the modeling choices result in differences that ultimately swing results in carbon cycle simulations - by as much as 20 percent. (http://dx.doi.org/10.1002/2013MS000252)

Engineering ultrasensitive probes of nanoscale physical and chemical processes

Scientists at Pacific Northwest National Laboratory found that sequences of Raman spectra recorded at a plasmonic junction, formed by a gold tip and a silver surface, exhibit dramatic intensity fluctuations, accompanied by switching from familiar vibrational line spectra of a molecule to broad band spectra of the same origin.

#AskEnergySaver: Renewable Energy

we asked you to share your renewable energy questions. To answer them, we reached out to Sarah Widder, a research engineer at the Energy Department's Pacific Northwest National Lab who focuses on improving the energy efficiency of our nation's buildings.

DOE agrees to pay 23.6M [dollars] to Energy Northwest

The Department of Energy has agreed to pay Energy Northwest almost 23.6 million [dollars] in damages for its continued failure to accept used nuclear fuel. It also has agreed to an annual claims process to continue to pay costs through 2016 without requiring Energy Northwest to prove damages in federal court.

Obama pushes green standards for everything but kitchen sink

Spurred by President Obama's climate action plan, the Department of Energy is pumping out new standards for refrigerators, dishwashers, air conditioners, ceiling fans, furnaces, boilers, water heaters, lamps, and many more appliances.

DOE 'Knowledgebase' links biologists, computer scientists to solve energy, environmental issues

If biologists wanted to determine the likely way a particular gene variant might increase a plant's yield for producing biofuels ..., they can do the analysis in a matter of hours, using the Department of Energy's Systems Biology Knowledgebase (KBase), a new computational platform to help the biological community analyze, store, and share data.

Simpler Process to Grow Germanium Nanowires Could Improve Lithium-Ion Batteries

ROLLA, Mo. - Researchers at Missouri University of Science and Technology have developed what they call "a simple, one-step method" to grow nanowires of germanium from an aqueous solution. Their process could make it more feasible to use germanium in lithium-ion batteries. (http://dx.doi.org/10.1021/nn503784d)

Single-cell genomics sheds light on nutrient and carbon cycling in Actinobacteria

Researchers assembled and compared draft genomes of acI Actinobacteria from single cells collected in four freshwater lakes in the United States and Europe. The single cells collected represented three different acI tribes of Actinobacteria, allowing researchers to learn more about their roles in carbon and other nutrient cycling.

We are Swimming in a Superhot Supernova Soup

Approximately 10 million years ago, a nearby cluster of stars erupted as a violent series of supernovae and, according to new observations, the million degree plasma from these powerful detonations surround the solar system today. (http://dx.doi.org/10.1038/nature13525)

Scientists craft a semiconductor junction only three atoms thick

Scientists have developed what they believe is the thinnest-possible semiconductor, a new class of nanoscale materials made in sheets only three atoms thick.(http://dx.doi.org/10.1038/nmat4064) (press release)

Great Recession took toll on workplace attitudes

(The Kansas City Star) - A poll shows American workers are unhappy, worried and pessimistic.

Train Your Brain to Thrive From 9 to 5

Many of today's work practices are more likely to harm, rather than help, brain health. Locating workers together in loud "cube farms" prevents employees from focusing on their own work, reducing productivity. Numerous meetings without focused agendas keep employees from spending time actually getting results. How many times do we stop and ask ourselves how much large meetings are costing the bottom-line? Drawing too many people into projects tricks us into believing we're building a consensus, but in reality, the true issues are not addressed and the time and talent wasted are unnerving.

Our House: Life 'underground' in a berm home

According to the Department of Energy, there are two kinds of earth-sheltered homes. An underground home is built entirely below the earth's grade, but generally gets light from windows that face a central courtyard. A berm house can remain somewhat above ground, with at least one wall being sheltered entirely by the earth.
