Imagine slipping into a jacket, shirt or skirt that powers your cell phone, fitness tracker and other personal electronic devices as you walk, wave and even when you are sitting down. A new, ultrathin energy harvesting system developed at Vanderbilt University's Nanomaterials and Energy Devices Laboratory has the potential to do just that.
With the introduction of CBETA, the Cornell-Brookhaven ERL Test Accelerator, Cornell University and Brookhaven National Laboratory scientists are following up on the concept of energy-recovering particle accelerators first introduced by physicist Maury Tigner at Cornell more than 50 years ago.
Redox metabolism was engineered in Yarrowia lipolytica to increase the availability of reducing molecules needed for lipid production.
Deeper soil layers are more sensitive to warming than previously thought.
Using one of the world's most powerful supercomputers--Titan, the 27-petaflop Cray XK7 at the Oak Ridge Leadership Computing Facility (OLCF)--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.
A new integrated climate model developed by Oak Ridge National Laboratory and other institutions is designed to reduce uncertainties in future climate predictions as it bridges Earth systems with energy and economic models and large-scale human impact data.
Microbial enzymes create precursors of nylon while avoiding harsh chemicals and energy-demanding heat.
India is pushing hard to electrify its automobile market, aiming to sell only electric vehicles (EVs) by 2030. But what impact will that shift have on the country's utilities and the grid? A new report by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has found that the prospective EV expansion will deliver economic benefits, help integrate renewable energy, and significantly reduce imports of foreign oil.
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.
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.
Scientists Create First Laboratory Generation of High-Energy Shock Waves That Accelerate Astrophysical Particles

State-of-the-art mass spectrometer delivers unprecedented capability to scientists.
A paper by graduate student Matthew Parsons describes the application of machine learning to avoiding plasma disruptions, which will be crucial to ensuring the longevity of future large tokamaks.
Today, the U.S. Department of Energy (DOE) announced the selection of three projects to receive up to $8 million, aimed at reducing the costs of producing algal biofuels and bioproducts.
In a milestone for studying a class of chemical reactions relevant to novel solar cells and memory storage devices, an international team of researchers working at the Department of Energy's SLAC National Accelerator Laboratory used an X-ray laser to watch "molecular breathing" - waves of subtle in-and-out motions of atoms - in real time and unprecedented detail.
Scientists have designed and constructed a prototype for a new solar cell that integrates multiple cells stacked into a single device capable of capturing nearly all of the energy in the solar spectrum.
A new Berkeley Lab algorithmic framework called multi-tiered iterative phasing (M-TIP) utilizes advanced mathematical techniques to determine 3D molecular structure of important nanoobjects like proteins and viruses from very sparse sets of noisy, single-particle data.
Researchers demonstrate a new technique that could lead to significantly higher power proton beams to answer tough scientific questions.
A new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells with large crystals intended to minimize current-robbing grain boundaries. The meniscus-assisted solution printing (MASP) technique boosts power conversion efficiencies to nearly 20 percent by controlling crystal size and orientation.
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.
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.
In the battle of the batteries, lithium-ion technology is the reigning champion. But a novel manganese and sodium-ion-based material developed at The University of Texas at Dallas might become a contender, offering a potentially lower-cost, more ecofriendly option to fuel next-generation devices and electric cars.
UW engineers have designed the first battery-free cellphone that can send and receive calls using only a few microwatts of power, which it harvests from ambient radio signals or light. It's a major step forward in moving beyond chargers, cords and dying phones.
Article describes first experimental finding of constant temperature throughout a fusion plasma.
A team led by the Department of Energy's Oak Ridge National Laboratory has used sophisticated neutron scattering techniques to detect an elusive quantum state known as the Higgs amplitude mode in a two-dimensional material.
