Research news on Plasma discharges

Plasma discharges as a research area focus on the generation, sustainment, and control of ionized gases under electric or electromagnetic fields, spanning regimes from low-pressure glow and radio-frequency discharges to atmospheric-pressure and pulsed power plasmas. The field investigates breakdown mechanisms, sheath formation, transport processes, non-equilibrium kinetics, and plasma–surface interactions using diagnostic techniques (e.g., spectroscopy, probes, imaging) and numerical modeling. Applications drive studies of plasma discharges for materials processing, lighting, plasma propulsion, environmental remediation, biomedical treatments, and fusion-relevant plasmas, with emphasis on understanding scaling laws, stability, power coupling, and energy partitioning to optimize performance and tailor plasma properties for specific technological and scientific objectives.

NASA fires up powerful lithium-fed thruster for trips to Mars

A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA's Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first ...

Plasma-catalytic system aims to cut livestock methane emissions

The CANMILK project is developing a plasma-based system suitable for direct operation in barns to reduce methane emissions from livestock. The goal is to capture dilute methane present in barn air and convert it into CO₂ ...
