A new approach to find unmarked gravesites could help narrow the scope and potentially speed up the search for clues during crime scene investigations. Geospatial researchers with the Department of Energy's Oak Ridge National Laboratory and forensic scientists at University of Tennessee used LIDAR to detect telltale signs of recently buried human remains.
The first full characterization measurement of an accelerator beam in six dimensions will advance the understanding and performance of current and planned accelerators around the world.
In a paper published online July 23 in Nature, a UW-led research team reports that the 2-D form of tungsten ditelluride can undergo "ferroelectric switching" -- a first for a exfoliated 2-D material. Ferroelectric materials can have applications in memory storage, capacitors, RFID card technologies and even medical sensors.
Some chemicals used to speed up the breakdown of plants for production of biofuels like ethanol are poison to the yeasts that turn the plant sugars into fuel. Researchers from the University of Wisconsin-Madison and several Department of Energy laboratories have identified two changes to a single gene that can make the yeast tolerate the pretreatment chemicals.
Scientists have discovered that the electrical resistance of this material changes in an unusual way under very high magnetic fields--a finding that could help direct the search for materials that can perfectly conduct electricity at room temperature.
A study in Nature revealed that turning up the heat accelerates spring greening in vegetation and delays fall color change. The research team measured plant greenness over three years at the SPRUCE study, a unique ecosystem-scale experiment operated by DOE's Oak Ridge National Laboratory.
The batteries of the future may be made out of paper. Researchers at Binghamton University, State University at New York have created a biodegradable, paper-based battery that is more efficient than previously possible
A team led by scientists at Berkeley Lab found a way to make a liquid-like state behave more like a solid, and then to reverse the process.
The first-ever computation of an atomic nucleus, the deuteron, on a quantum chip demonstrates that even today's rudimentary quantum computers can solve nuclear physics questions.
Proton-irradiated thorium targets are successfully mined for therapeutic radium isotopes.
Researchers at the Department of Energy's SLAC National Accelerator Laboratory have developed a new imaging technique to better understand the mechanisms that lead to hearing loss when aminoglycosides are introduced to the body. Using the lab's Linac Coherent Light Source (LCLS) X-ray laser and Stanford Synchrotron Lightsource (SSRL), SLAC researchers, in collaboration with researchers at Stanford University, were able to observe interactions between the drugs and bacterial ribosomes at both extremely low and room temperatures, revealing never-before-seen details.
In response to the population decline of pollinating insects, such as wild bees and monarch butterflies, Argonne researchers are investigating ways to use "pollinator-friendly solar power."
Researchers have identified details of how certain plants scavenge and accumulate pollutants in contaminated soil. Their work revealed that plant roots effectively "lock up" toxic arsenic found loose in mine tailings--piles of crushed rock, fluid, and soil left behind after the extraction of minerals and metals.
Scientists at the Florida State University-headquartered National High Magnetic Field Laboratory have discovered a behavior in materials called cuprates that suggests they carry current in a way entirely different from conventional metals such as copper. The research, published today in the journal Science, adds new meaning to the materials' moniker, "strange metals."
Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive.
Using 100-year-old minerals processing methods, chemical engineering students have found a solution to a looming 21st-century problem: how to economically recycle lithium ion batteries.
A group of researchers, including scientists at the Department of Energy's SLAC National Accelerator Laboratory and Fermi National Accelerator Laboratory, summarize current applications and future prospects of machine learning in particle physics in a paper published today in Nature.
Hollow molecular structures known as COFs suffer from an inherent problem: It's difficult to keep a network of COFs connected in harsh chemical environments. Now, a team at the Berkeley Lab has used a chemical process discovered decades ago to make the linkages between COFs much more sturdy, and to give the COFs new characteristics that could expand their applications.
The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, according to a new study in the journal Nature. Blame microbes: When they chew on decaying leaves and dead plants, they convert a storehouse of carbon into carbon dioxide that enters the atmosphere.
ORNL story tips: Residents' shared desire for water security benefits neighborhoods; 3D printed molds for concrete facades promise lower cost, production time; ORNL engineered the edges of structures in 2D crystals; chasing runaway electrons in fusion plasmas; new tools to understand U.S. waterways and identify potential hydropower sites; better materials for 3D-printed permanent magnets could last longer, perform better.
Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve detection sensitivity to chemicals in explosives or drugs.
The dominant existing technology--silicon--is more than 90 percent of the way to its theoretical efficiency limit. More efficient technologies will be more expensive. ASU study finds the acceptable intersection of costs vs. efficiency.
Columbia University researchers report the use of SRS microscopy, a technique widely used in biomedical studies, to explore the mechanism behind dendrite growth in lithium batteries, the first team of material scientists to directly observe ion transport in electrolytes. They were able to see not only why lithium dendrites form but also how to inhibit their growth. Visualizing ion movement could help improve the performance of electrochemical devices, from batteries to fuel cells to sensors.
Argonne researchers find that tin is a silicon-friendly alternative for production of solid-state memory components.
Chemical engineers are using the summer staple in testing methods to improve efficiency of diesel engines.
