Topside Ionospheric Ambipolar Diffusion Derived From ICON Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The scarcity of ambipolar diffusion observations has constrained our understanding of ionospheric physical processes. We present the first comprehensive analysis of topside ionospheric ambipolar diffusion using the difference between the field‐aligned ion drifts and neutral winds observed by the Ionospheric Connection Explorer (ICON) satellite.

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

open access: yesAdvanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Particle Size Matters – Impact of Particle Size and Crucible Geometry on Sublimation Behavior of Formamidinium Iodide

open access: yesAdvanced Materials Technologies, Volume 11, Issue 3, 5 February 2026.
FAI precursor particle size and sublimation crucible geometry critically determine vapor flux directionality and deposition uniformity in thermal sublimation processes. Conical crucibles exhibit particle‐size‐dependent beam focusing, while cylindrical crucibles show a much more homogeneous deposition due to de‐focusing effects of the emitted vapor flux.
