Iowa State engineers have developed a process called autothermal pyrolysis that breaks down biomass for fuel and fertilizer. A recently announced grant from the Department of Energy will support studies of the process, including development of models and design tools that could reduce the risk of scaling up the technology for commercial use.
In a recent study, researchers developed a new holographic method called in-flight holography. With this method, they were able to demonstrate the first X-ray holograms of nano-sized viruses that were not attached to any surface.
An international team led by researchers at Berkeley Lab used advanced techniques in electron microscopy to show how the ratio of materials that make up a lithium-ion battery electrode affects its structure at the atomic level, and how the surface is very different from the rest of the material.
The present study addresses the feasibility of reinforced concrete columns totally reinforced with glass fiber-reinforced polymer (GFRP) bars achieving the drift requirements specified in various codes.
New "smart glass" technology developed at the University of Delaware could make curtains and blinds obsolete. This isn't the first "smart glass," but it's one-tenth the price of other versions and more transparent in its transparent state and more reflective in its reflective state than competitors.
Researchers have discovered more details about the way certain materials hold a static charge even after two surfaces separate, information that could help improve devices that leverage such energy as a power source.
Iron may be more valuable than platinum. Sometimes.
Article describes use of new diagnostics to advance understanding of the plasma nanosynthesis of widely used nanoparticles.
New research from Arizona State University shows that using a 3-dimensional layer of Polydimethylsiloxane (PDMS) can mitigate dendrite formation and stands to both dramatically extend battery life and diminish safety risks.
While it may be the era of supercomputers and "big data," without smart methods to mine all that data, it's only so much digital detritus. Now researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have come up with a novel machine learning method that enables scientists to derive insights from systems of previously intractable complexity in record time.
Scientists have used experiments at Berkeley Lab to retrace the chemical steps leading to the creation of complex hydrocarbons in space. They showed pathways to forming 2-D carbon-based nanostructures in a mix of heated gases.
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.
The CUORE experiment set the tightest limits yet on the rare decay of tellurium-130, providing insights into the nature of neutrinos.
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.
