Nancy Ambrosiano, Los Alamos National Laboratorynwa@lanl.gov, 505.667.0471 David_Cullen_ORNL_AC-STEM.jpg LOS ALAMOS, N.M., Aug. 3, 2017—In order to reduce the cost of next-generation polymer electrolyte fuel cells for vehicles, researchers have been developing alternatives to the prohibitively expensive platinum and platinum-group metal (PGM) catalysts currently used in fuel cell electrodes. New work at Los Alamos and Oak Ridge national laboratories is resolving difficult fuel-cell performance questions, both in determining efficient new materials and understanding how they work at an atomic level.

Anthony Walker: Modeling the natural world

August 3, 2017 - During the workday, Anthony Walker spends considerable time designing models to advance our understanding of Earth’s biological systems. In the evenings and on weekends, he takes a more hands-on approach to the natural world, whether working in his garden or out kayaking on area waterways.The terrestrial ecosystem modeler has tackled a variety of tasks since arriving at Oak Ridge National Laboratory 4 years ago, including leading an international group of scientists exploring how forests respond to elevated levels of carbon dioxide (CO2).

Batteries – Promising electrode material

August 1, 2017 - An Oak Ridge National Laboratory–led team discovered that vanadium dioxide in a crystalline thin film makes an outstanding electrode for lithium-ion batteries. Theory and computation predicted a high capacity for lithium storage, which experiments confirmed with tests in coin cells. Advanced microscopy proved lithium ions pack into a rigid framework, and ions speed through sites favorable for their adsorption which are abundant along the open channels.

Chemistry – Discovery doubles output

August 1, 2017 - A simplified catalyst production process developed by Oak Ridge National Laboratory could double the output of high-value chemicals used in making materials found in soda bottles and tires. Scientists found that single gallium cations are the key to increasing production of benzene, toluene and xylenes, or BTX, commodity chemicals commonly used to make plastics and rubber.

Fusion – Blocking the heat

August 1, 2017 - Fusion scientists from Oak Ridge National Laboratory, as part of the DIII-D National Fusion Facility team at General Atomics, are studying an approach to insulate the reactor’s innermost wall that surrounds the burning plasma from the energy created when hydrogen isotopes are heated to millions of degrees. The national team created a buffer that traps neutral gas between the plasma’s edge, which is cooler than the core but still hotter than the sun, and the interior wall at points where hot ions and atomic particles might make contact.

Amit Naskar: Materials déjà vu

Image
Amit_Naskar_2 July 24, 2017 − Finding new energy uses for underrated materials is a recurring theme across Amit Naskar’s research portfolio. Since joining Oak Ridge National Laboratory in 2006, he has studied low-cost polymers as carbon fiber precursors, turning lignin−a byproduct of biofuel production−into renewable thermoplastics and creating carbon battery electrodes from recycled tires.

Hector Santos-Villalobos: Sharper images

July 21, 2017 – At the heart of Hector Santos-Villalobos’ work is the need to get a better look at the unknown, whether it is the structure of an underground geothermal reservoir, meter-thick concrete surrounding a nuclear reactor, or the fine details of the human eye. It may seem appropriate, then, to bring his research and the path that led him to it into focus.
