Scientists looking to hydrogen as a next-generation clean energy source are developing hydrogen-sensing technologies, the most common of which uses palladium-based thin films because palladium readily absorbs hydrogen gas. However, it also readily absorbs other gases, decreasing the overall efficiency of these sensors. Researchers conducted a systematic study of hydrogen detection using the Extraordinary Hall Effect to measure the hydrogen magnetization response in cobalt-palladium thin films, and reports in the Journal of Applied Physics.
Argonne researchers are using nanoparticles to make photodetectors better able to handle the ultraviolet radiation produced in high-energy physics experiments.
For fusion power plants to be effective, scientists must find a way to trigger the low-to-high confinement transition, or "L-H transition" for short. Scientists have observed that the L-H transition is always associated with zonal flows of plasma. Theoretically, zonal flows in a plasma consist of both a stationary flow with a near-zero frequency and one that oscillates at a higher frequency called the geodesic acoustic mode. For the first time, researchers have detected GAM at two different points simultaneously within the reactor. This new experimental setup will be a useful diagnostic tool for investigating the physics of zonal flows, and their role in the L-H transition. The researchers report these findings in a new paper published in Physics of Plasmas.

Researchers found that using bio-sequestration to capture carbon produced by U.S. coal-fired plants even after carbon capture and storage would require using 62 percent of the nation's arable land for that process, or 89 percent of all U.S. land with average forest cover. In comparison, offsetting the amount of carbon produced by manufacturing solar panels is 13 times less land, making it a far more viable option.
