Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.

Measurement of the volume CT dose index on spiral CT scanning with a real‐time ionization chamber

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background The measurement of computed tomography dose index 100 (CTDI100$CTD{{I}_{100}}$), which is feasible only through axial scanning, requires that the clinical spiral protocols be replaced with those for axial scanning. The real‐time ionization chamber detects the integral of radiation dose rate profile, enabling the direct verification ...

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?
