Finding the missing particles
DOE/Pacific Northwest National Laboratory
For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data. All of the assumptions were proven false by Dr. Alla Zelenyuk and her colleagues.

Out with heavy metal
DOE/Pacific Northwest National LaboratoryPeer-Reviewed Publication
Researchers have demonstrated a new process for the expanded use of lightweight aluminum in cars and trucks at the speed, scale, quality and consistency required by the auto industry. The process reduces production time and costs while yielding strong and lightweight parts, for example delivering a car door that is 62 percent lighter and 25 percent cheaper than that produced with today's manufacturing methods.

Three PNNL scientists receive DOE Early Career Research Program awards, research funding
DOE/Pacific Northwest National LaboratoryGrant and Award Announcement
Three scientists at Pacific Northwest National Laboratory have been selected to receive 2015 Early Career Research Program research grants. The trio were among just 44 recipients nationwide to receive the annual research awards. Under the program, David Heldebrant, Dongsheng Li and Brent VanDevender will each receive five-year research grants that fund work designed to reduce carbon emissions, create new materials for energy storage and measure the mass of some of the smallest components of the universe.

Special science call projects announced
DOE/Environmental Molecular Sciences Laboratory
EMSL's Special Science Call for Proposals ran from mid-April through September and generated 23 accepted studies. The call challenged prospective users to submit high-impact research projects that took advantage of EMSL's technical resources including RadEMSL, the Quiet Wing microscopy and NanoSIMS capabilities, and HRMAC. The research associated with the call is progressing, and the projects will soon start delivering important scientific findings.

Ground control
DOE/Environmental Molecular Sciences Laboratory
The United Nations General Assembly declared 2015 the International Year of Soils. Soil is critical for food production and climate regulation. It's a complex underground ecosystem of organisms that process decaying debris to enrich the land as well as store and release carbon into the atmosphere. However, human activity and changing climate are impacting this environmental system. Scientists working at EMSL are trying to understand the complexities of soil to develop better sustainable land management to protect it.

Electron chirp: Cyclotron radiation from single electrons measured directly for first time
DOE/Pacific Northwest National LaboratoryPeer-Reviewed Publication
A group of almost 30 scientists and engineers from six research institutions reported the direct detection of cyclotron radiation from individual electrons April 20 in Physical Review Letters. They used a specially developed spectroscopic method that allowed them to measure the energy of electrons, one single electron at a time. The method provides a new way to potentially measure the mass of the neutrino, a subatomic particle that weighs at most two-billionths of a proton.

Packing heat: New fluid makes untapped geothermal energy cleaner
DOE/Pacific Northwest National LaboratoryPeer-Reviewed Publication
More American homes could be powered by the Earth's natural underground heat with a nontoxic fluid that could cut in half the amount of water needed for a new power generation method called enhanced geothermal systems.

Erupting electrodes: How recharging leaves behind microscopic debris inside batteries
DOE/Pacific Northwest National LaboratoryPeer-Reviewed Publication
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.
