Public Release: 18-Jul-2017 3-D models help scientists gauge flood impact
Using one of the world's most powerful supercomputers, a University of Iowa team performed one of the first highly resolved, 3-D, volume-of-fluid Reynolds-averaged Navier-Stokes (RANS) simulations of a dam break in a natural environment. The simulation allowed the team to map precise water levels for actual flood events over time.

Nature Climate Change Titan simulations show importance of close 2-way coupling between human and Earth systems
By using supercomputers such as the Oak Ridge Leadership Computing Facility's Titan, a large multidisciplinary team of scientists developed a new integrated climate model designed to reduce uncertainties in future climate predictions as it bridges Earth systems with energy and economic models and large-scale human impact data.
Public Release: 17-Jul-2017 Lighting up the study of low-density materials
Sandia National Laboratories studies myriads of low-density materials, from laminate layers in airplane wings to foams and epoxies that cushion parts. So Sandia borrowed and refined a technique being studied by the medical field, X-ray phase contrast imaging, to look inside the softer side of things without taking them apart.

Nature Communications Studying argon gas trapped in two-dimensional array of tiny 'cages'
For the first time, scientists have trapped a noble gas in a two-dimensional porous structure at room temperature. This achievement will enable detailed studies of individual gas atoms in confinement -- research that could inform the design of new materials for gas separation and nuclear waste remediation.

Nature Communications Mica provides clue to how water transports minerals
In a new study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, in collaboration with the University of Illinois at Chicago and the University of Delaware, chemists have been able to look at the interface between water and muscovite mica, a flat mineral commonly found in granite, soils and many sediments. In particular, the researchers looked at the capture and release of rubidium - a metal closely related to but more easily singled out than common elements like potassium and sodium.
Public Release: 13-Jul-2017 Optimizing hydrogen-powered passenger ferries focus of Sandia Labs study
Maritime transportation has emerged as one solution to the traffic gridlock that plagues coastal cities. But with urban passenger ferries operating in sensitive environments and tourist areas, hydrogen fuel cell-powered passenger ferries offer a quiet, zero-emission alternative to conventional diesel vessels.

Science Scientists get first direct look at how electrons 'dance' with vibrating atoms
Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons move in sync with atomic vibrations rippling through an exotic material, as if they were dancing to the same beat.

Science Electron orbitals may hold key to unifying concept of high-temperature superconductivity
A team of scientists has found evidence for a new type of electron pairing that may broaden the search for new high-temperature superconductors. The findings provide the basis for a unifying description of how radically different copper- and iron-based 'parent' materials can develop the ability to carry electrical current with no resistance at strikingly high temperatures.

Proceedings of the National Academy of Sciences New class of 'soft' semiconductors could transform HD displays
New research by Berkeley Lab scientists could help usher in a new generation of high-definition displays, optoelectronic devices, photodetectors, and more. They have shown that a class of 'soft' semiconductors can be used to emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The work could challenge quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light.
