Berkeley Lab and several collaborating institutions have successfully demonstrated a machine-learning technique to accelerate discovery of materials for film capacitors — crucial components in electrification and renewable energy technologies. The technique was used to screen a library of nearly 50,000 chemical structures to identify a compound with record-breaking performance.
A team of scientists with two Department of Energy Bioenergy Research Centers — the Center for Bioenergy Innovation, or CBI, at Oak Ridge National Laboratory and the Center for Advanced Bioenergy and Bioproducts Innovation, or CABBI, at the University of Illinois Urbana-Champaign — identified a gene in a poplar tree that enhances photosynthesis and can boost tree height by about 30% in the field and by as much as 200% in the greenhouse.
Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton. The results reveal that quarks and gluons, the fundamental building blocks that make up a proton’s structure, are subject to so-called quantum entanglement.
A chemical reaction can convert two polluting greenhouse gases into valuable building blocks for cleaner fuels and feedstocks, but the high temperature required for the reaction also deactivates the catalyst. A team led by the Department of Energy’s Oak Ridge National Laboratory has found a way to thwart deactivation. The strategy may apply broadly to other catalysts.
The cost of reversing the effects of climate change—restoring melted polar sea ice, for example—quickly climbs nearly fourfold soon after a tipping point is crossed, according to new work publishing in the journal npj Climate and Atmospheric Science on Tuesday, Nov. 26. Much work has been done to explore the environmental costs tied to climate change. But this new study marks the first time researchers have quantified the costs of controlling tipping points before and after they unfold.
