Atmospheric helium levels are rising, research confirms

Scientists at Scripps Institution of Oceanography at UC San Diego used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists ...

Vacuum arcs spark new interest

Whenever two pieces of metal at different voltages are brought near each other, as when an appliance is plugged into a live socket, there is a chance there will be an arc between them. Most of the arcs people see are a breakdown ...

Researchers develop a reactor that can destroy 'forever chemicals'

"Forever chemicals," named for their ability to persist in water and soil, are a class of molecules that are ever-present in our daily lives, including food packaging and household cleaning products. Because these chemicals ...

Major step forward in the production of 'green' hydrogen

The first thermodynamically-reversible chemical reactor capable of producing hydrogen as a pure product stream represents a "transformational" step forward in the chemical industry, the authors of a new study claim.

Multi-scale simulations solve a plasma turbulence mystery

Cutting-edge simulations run at Lawrence Berkeley National Laboratory's National Energy Research Scientific Computing Center (NERSC) over a two-year period are helping physicists better understand what influences the behavior ...

UK stays cautious over thorium as nuclear fuel

(Phys.org)—The claim is dramatic: An alternative nuclear fuel that could offer a safer and more abundant alternative to the uranium that powers conventional reactors. That is what supporters have to say about thorium, a ...
