UPTON, NY--Even plants have to live on an energy budget. While they're known for converting solar energy into chemical energy in the form of sugars, plants have sophisticated biochemical mechanisms for regulating how they spend that energy. Making oils costs a lot. By exploring the details of this delicate energy balance, a group of scientists from the U.
A new technique synchronized high-energy electrons with an ultrafast laser pulse to probe how vibrational states of atoms change in time.
A new energy-efficient separation of rare earth elements could provide a new domestic source of critical materials.
Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2D) ceramics called MXenes are contenders.
The U.S. Department of Energy's Ames Laboratory has successfully created the first pure, single-crystal sample of a new iron arsenide superconductor, CaKFe4As4, and studies of this material have called into question some long-standing theoretical models of superconductivity.
Soils could release much more CO2 than expected into the atmosphere as the climate warms, according to new research by Berkeley Lab scientists. Their findings are based on a field experiment that, for the first time, explored what happens to organic carbon trapped in soil when all soil layers are warmed, which in this case extend to a depth of 100 centimeters.
Better storm surge prediction capabilities could help reduce the impacts of extreme weather events, such as hurricanes.
Scientists find that water-related energy consumption is increasing across the globe, with pronounced differences across regions and sectors.
When a team led by the Department of Energy's Oak Ridge National Laboratory tried to verify that shrinking the nanoparticle size would adversely affect the mechanical properties of polymer nanocomposites, they got a big surprise.
Scientists at Argonne have invented a new foam, called Oleo Sponge, that not only easily adsorbs spilled oil from water, but is also reusable and can pull dispersed oil from the entire water column--not just the surface.
Chad Parish of Oak Ridge National Laboratory is senior author of a study that explored degradation of tungsten under reactor-relevant conditions. Learning how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials.
Scientists at Berkeley Lab and Caltech have--in just two years--nearly doubled the number of materials known to have potential for use in solar fuels. They did so by developing a process that promises to speed the discovery of commercially viable generation of solar fuels that could replace coal, oil, and other fossil fuels.
Scientists discover that the iron sulfide battery material undergoes significant changes in its microstructure and chemical composition as sodium ions enter and leave the material during the first discharge/charge cycle, leading to an initial loss in battery capacity.
Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites conducted, in part, at Berkeley Lab.
Nanotextures inspired by cone-shaped structures found on the surface of cicada wings could inform new designs for materials prone to fogging, such as car and aircraft windshields.
Rapid prototyping aids small manufacturer; accelerated method could separate CO2 from flue gases; EBM technique controls microstructure, locates properties in 3-D printed parts; open-source, user-friendly software monitors, controls energy use; drones to aid electric utilities to enhance safety, system reliability; ORNL cyberspace conf.
Summary (1-3 sentences): Certain materials can be swayed by their neighbors to become magnetic, according to a new Argonne study.
