Researchers from the University of Illinois at Chicago and Lawrence Berkeley National Laboratory have developed a new technique that lets them pinpoint the location of chemical reactions happening inside lithium-ion batteries in three dimensions at the nanoscale level. Their results are published in the journal Nature Communications.
Building on methods they used to assess the impact of hurricanes such as Katrina, Gustav, and Rita on forests and tree mortality, scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have produced a rapid mapping of the disturbance intensity across Puerto Rico's forests with the help of Google Earth Engine.
Physicians have long used CT scans to get 3D imagery of the inner workings of the human body. Now, physicists are working toward getting their first CT scans of the inner workings of the nucleus. A measurement of quarks in helium nuclei published last fall in Physical Review Letters demonstrates that 3D imaging of the inner structure of the nucleus is now possible.
ORNL model could better predict tiny methylmercury pockets lurking in creek algae; engines work smarter with new fuel innovation; making narrow metallic structures to advance tiny electronics, drug delivery; certain enzymes that try to break down antibiotics may inform better drug designs for fighting resistant bacteria; current software simulations for small modular reactors upscaled to run on future supercomputers.
Global models may be underestimating net wetland methane emissions.
Using NERSC supercomputers, astrophysicists at Berkeley Lab and the University of Portsmouth discovered how to control the effects of "micolensing." Armed with this knowledge they believe they will be able to find 1000 strongly lensed Type Ia supernovae in real-time from LSST data--that's 20 times more than previous expectations.

Engineers from the University of Maryland created a non-flammable battery from ceramic materials by using a 'melty' layer that, when cool, unites a solid-state battery.
Scientists have discovered a novel chemical state, first proposed about 90 years ago, that enables a high-performance, low-cost sodium-ion battery. The battery could quickly and efficiently store and distribute energy produced by solar panels and wind turbines across the electrical grid.
Scientists at PPPL have discovered key conditions that give rise to fast magnetic reconnection, the process that triggers solar flares, auroras, and geomagnetic storms that can disrupt signal transmissions and other electrical activities, including cell phone service.
Researchers from Argonne and Harvard University built a metasurface-based lens atop a Micro-Electro-Mechanical System (MEMS) platform. The result is a new, infrared light-focusing system that combines the best features of both technologies while reducing the size of the optical system.
The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science.
Lithium ions have to travel through layers of molecules in the electrolyte liquid before they can enter or leave a lithium-ion battery electrode. Tweaking this process could help batteries charge faster.
A team of researchers from ORNL and the University of Alabama at Birmingham recently developed the antioxidant manganoporphyrin, a new polymer that could potentially improve drug delivery methods and other biomedical applications. Using neutrons, they studied the strength and efficiency of a compound made from this material and tannic acid, a natural antioxidant.
In two recent publications, teams of researchers led by Penn State provide new understanding of why synthetic two-dimensional materials often perform orders of magnitude worse than predicted, and how to improve their performance in future electronics, photonics, and memory storage applications.
Researchers have developed a method that will help natural gas experts better understand shale samples and eventually help them decide whether to invest time and resources to extract gas from the formation the samples came from.
A surprising discovery could potentially offer major advantages in speed, heat dissipation and power consumption in electronic devices.

Colossal magnetoresistance at terahertz frequencies in thin composites boosts novel memory devices operated at extremely high speed.
Menlo Park, Calif. --Scientists have turned the smallest possible bits of diamond and other super-hard specks into "molecular anvils" that squeeze and twist molecules until chemical bonds break and atoms exchange electrons. These are the first such chemical reactions triggered by mechanical pressure alone, and researchers say the method offers a new way to do chemistry at the molecular level that is greener, more efficient and much more precise.
Berkeley Lab mathematicians have developed a new approach to machine learning aimed at experimental imaging data. Rather than relying on the tens or hundreds of thousands of images used by typical machine learning methods, this new approach "learns" much more quickly and requires far fewer images.
