Novel capability enables first test of real turbine engine conditions
Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between the US Department of Energy's Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.

Elusive quantum transformations found near absolute zero
Scientists mapped quantum phase transitions at temperatures colder than interstellar space. The ultra-cold conditions isolated the fluctuations that define the electronic, magnetic, and thermodynamic performance of metallic materials. The research provides new methods to identify and understand materials with powerful and unexpected properties, including superconductivity.

Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.

Angling chromium to let oxygen through
Researchers have been trying to increase the efficiency of solid oxide fuel cells by lowering the temperatures at which they run. More efficient fuel cells might gain wider use in vehicles or as quiet, pollution-free, neighborhood electricity generating stations. A serendipitous finding has resulted in a semiconducting material that could enable fuel cells to operate at temperatures two-thirds lower than current technology, scientists reported Aug. 18 in Nature Communications.

PPPL scientists take key step toward solving a major astrophysical mystery
Magnetic reconnection can trigger geomagnetic storms that disrupt cell phone service, damage satellites and black out power grids. But how reconnection, in which the magnetic field lines in plasma snap apart and violently reconnect, transforms magnetic energy into explosive particle energy remains a major unsolved problem in plasma astrophysics.

National Renewable Energy Laboratory updates cetane data used for development of energy efficient fuels and engines
The Energy Department's National Renewable Energy Laboratory has released a long-anticipated update to the source-of-record for cetane number data. This information is vital to the development of new, energy-efficient, low-carbon fuels and compatible engines. Researchers, as well as members of the engine, vehicle, and fuel industries, rely on these numbers to target compounds for development of new fuels capable of greater energy efficiency, cleaner emissions, and maximum performance in diesel engines.

Buckyballs and diamondoids join forces in tiny electronic gadget
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

Birth of a mineral
One of the most important molecules on earth, calcium carbonate crystallizes into chalk, shells and minerals the world over. In a study led by the Department of Energy's Pacific Northwest National Laboratory, researchers used a powerful microscope that allows them to see the birth of crystals in real time, giving them a peek at how different calcium carbonate crystals form, they report in Sept. 5 issue of Science.

Argonne scientists pioneer strategy for creating new materials
Making something new is never easy. Scientists constantly theorize about new materials, but when the material is manufactured it doesn't always work as expected. To create a new strategy for designing materials, scientists at the Department of Energy's Argonne National Laboratory combined two different approaches at two different facilities to synthesize new materials. This new strategy gives faster feedback on what growth schemes are best, thus shortening the timeframe to manufacture a new, stable material for energy transport and conversion applications.

Researchers map quantum vortices inside superfluid helium nanodroplets
Scientists have, for the first time, characterized so-called quantum vortices that swirl within tiny droplets of liquid helium. The research, led by scientists at the US Department of Energy's Lawrence Berkeley National Laboratory , the University of Southern California, and SLAC National Accelerator Laboratory, confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues to study quantum rotation.

X-ray laser probes tiny quantum tornadoes in superfluid droplets
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum 'tornadoes' inside microscopic droplets of supercooled liquid helium -- the first time this formation has been seen at such a tiny scale. The findings by an international research team provide new insight on the strange nanoscale traits of a so-called 'superfluid' state of liquid helium.
