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.
Energy stored in thermochemical materials can effectively heat indoor spaces, particularly in humid regions, according to researchers with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
