Electron–Ion Temperature Ratio in Astrophysical Shocks
The Astrophysical Journal, 2023 Collisionless shock waves in supernova remnants and the solar wind heat electrons less effectively than they heat ions, as is predicted by kinetic simulations.

Combined ion and atom trap for low temperature ion-atom physics [PDF]
Applied Physics B, 2011 We report an experimental apparatus and technique which simultaneously traps ions and cold atoms with spatial overlap. Such an apparatus is motivated by the study of ion-atom processes at temperatures ranging from hot to ultra-cold.

Enhanced sodium storage in hard carbon via solvent co-intercalation electrolyte enabling Ah-level pouch cells at low temperatures [PDF]
Nature CommunicationsSodium ion batteries are attracting extensive interest due to their low cost and abundant sodium resources. However, sodium ion batteries still suffer from severe performance degradation at low temperatures due to the conflict between ion desolvation and

Effect of edge ion temperature on the divertor tungsten sputtering in WEST
Nuclear Fusion, 2023 The influence of upstream ion temperature in the scrape-off layer (SOL) on the tungsten (W) sputtering in the divertor is studied in the WEST tokamak. For an almost constant power into the SOL, the upstream ion temperature and its ratio over the electron

MAVEN‐STATIC Observations of Ion Temperature and Initial Ion Acceleration in the Martian Ionosphere
Geophysical Research Letters, 2022 Though ion escape to space is an important mechanism for atmospheric loss at Mars, the processes that accelerate ions to escape velocity have not been fully identified and quantified.

Review of the NPA Diagnostic Application at Globus-M/M2
Atoms, 2023 The application of a neutral particle analyzer (NPA) diagnostic at the Globus-M/M2 spherical tokamaks is discussed. Physical principles of the diagnostic are reviewed. Two general approaches—active and passive measurements—are described.

Building a Temperature-Sensitive Ion Channel [PDF]
Cell, 2014 The biophysical basis of temperature-sensitive ion channel gating has been a tough nut to crack. Chowdhury, et al. use a protein engineering approach to render a temperature-insensitive voltage-gated channel cold- or heat-responsive to reveal principles for temperature-gating and a plausible model for molecularly enabling this mode of environmental ...
