Absorption of Broadband Low‐Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing

Advanced Science, Volume 13, Issue 56, 9 October 2026.
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Wireless Power Transfer Performance for Unmanned Aerial Vehicle Charging

Applied Research, Volume 5, Issue 5, October 2026.
A selectively powered hexagonal transmitter array combined with a novel L‐shaped pickup coil is proposed for UAV wireless charging. Finite element simulations show the design achieves higher uncompensated power and greater positional stability than a benchmark coil, offering a promising direction towards scalable, misalignment‐tolerant charging ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 668-681, October/December 2026.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...
