A Contrast‐Agnostic Method for Ultra‐High Resolution Claustrum Segmentation

Human Brain Mapping, Volume 46, Issue 12, 15 August 2025.
The claustrum is a still poorly understood structure, with limited neuroimaging tools available for its study. Here we propose a method for automatic claustrum segmentation at ultra‐high resolution (0.35 mm), which can be applied to images of any contrast and resolution. The method is accurate, robust, and achieves excellent generalization.

Investigation of 3D Wave Propagation in Foam‐Core Functionally Graded Material Magneto‐Piezoelectric Smart Nanoplates

Advanced Engineering Materials, Volume 27, Issue 16, August 2025.
This study reveals how wave propagation in FG‐MEE nanoplates can be tuned via material gradients, porosity, and external fields. Using NSGT and Hamilton's principle, analytical solutions capture key dispersion behaviors. Findings highlight the potential of smart nanoplates for adaptive control in high‐performance applications like sonar and aerospace ...

Single Cu Atoms Anchored Energetic COFs as Combustion Catalytic Promoters toward Rapid and Concentrated Thermal Decomposition of Ammonium Perchlorate

Advanced Science, Volume 12, Issue 29, August 7, 2025.
Introducing energetic Cu‐based metal salts into the covalent organic frameworks (COFs) structure, Cu is in single‐atom form anchored to the framework, with energetic anions confined in the COFs structure. The synergistic interaction between single Cu atoms and the anions accelerates the reaction kinetics of ammonium perchlorate (AP) decomposition ...

Solid State Defect Emitters With no Electrical Activity

Advanced Science, Volume 12, Issue 30, August 14, 2025.
Point defects may introduce in‐gap states that alter electrical properties and lower the optical excitation threshold. It is thus widely assumed that solid‐state defect emitters alter the host conductivity. This study demonstrates, on a particular defect in 4H silicon carbide, that a yet unrecognized class of point defects exists that are optically ...

On the Enhanced p‐Type Performance of Back‐Gated WS2 Devices

Advanced Electronic Materials, Volume 11, Issue 13, August 20, 2025.
A scalable method for directly growing WS2 enables robust and persistent p‐type behavior in back‐gated FETs, independent of metal contacts, thickness, or ambient conditions. Electrical measurements reveal minimal Schottky barrier heights and stable thermionic transport, while first‐principles simulations suggest tungsten vacancies or WO3 species as the
