How Hot Is Too Hot in Fusion?

Fusion, the energy that powers the stars, might one day provide abundant energy here on Earth. In a nuclear fusion reactor, the hot, charged gas known as plasma reaches out of this world temperatures at 150 million degrees Celsius, or 10 times hotter than the center of the sun. The…

Putting the Pedal to the Metal in the Hunt for Alloys

High-temperature alloys, often used in power plants and automobile engines, are valued in engineering because they can withstand temperatures that are a high fraction of their melting point. Operating power plants and engines at higher temperatures typically allows for more efficient energy generation, so developing higher temperature alloys is desirable.…

Researchers Seek Sigma Meson on the Path to Heavier Hadrons

Schematic diagrams showing possible quark propagation channels in pion-pion scattering relevant for the sigma meson. Often, researchers aim for a distant horizon with respect to their research goals. When they get there, they plot their course for the next far-off landmark. Throughout the 20th century, researchers tried to understand the…
