A closer look at the perfect fluid
By combining data from two high-energy accelerators, nuclear scientists have refined the measurement of a remarkable property of exotic matter known as quark-gluon plasma. The findings reveal new aspects of the ultra-hot, 'perfect fluid' that give clues to the state of the young universe just microseconds after the big bang.

Hide and seek: Sterile neutrinos remain elusive
The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a possible new type of neutrino beyond the three known neutrino 'flavors,' or types. The existence of this elusive particle, if proven, would have a profound impact on our understanding of the universe, and could impact the design of future neutrino experiments.

Simulations reveal an unusual death for ancient stars
Certain primordial stars -- those 55,000 and 56,000 times the mass of our sun, or solar masses -- may have died unusually. In death, these objects -- among the universe's first generation of stars -- would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

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.
