Advancements in Multipath Mitigation for GNSS Receivers: Review of Channel Estimation Techniques

open access: yesSpace: Science & Technology
Multipath interference poses substantial challenges to global navigation satellite system (GNSS) receivers, leading to inaccuracies in the time of arrival (TOA) measurement of the line of sight (LOS) signal. Therefore, to mitigate the impact of multipath

Phase Transformation‐Assisted Nucleation and Growth of a Single‐Phase FeCoNiCuNb Alloy

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
The multi‐component crystal nucleus transitions between crystalline and amorphous states, generating vacancies that facilitate the incorporation of refractory elements. This process enables the formation of refractory high‐entropy alloys. Abstract High‐entropy alloys utilize high configurational entropy to stabilize solid solutions, suppress ...

Ultra‐Fast, Low‐Resistance Nano Gap Electromechanical Switch for Power Gating Applications

open access: yesAdvanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.
An ultra‐small 20 nm air gap and a high‐stiffness architecture enable a MEMS power‐gating switch that combines 0.95 Ω on‐resistance with 30 ns switching while maintaining off‐state leakage below 100 fA. Fabricated below 200 °C, the device is compatible with BEOL and monolithic 3D integration, overcoming the long‐standing resistance–speed trade‐off ...
