Diverse Responses in Lattice Thermal Conductivity of n‐Type/p‐Type Wurtzite Semiconductors Driven by Asymmetric Electron‐Phonon Interactions

Advanced Science, EarlyView.
It is traditionally thought that the electron‐phonon interactions have a significant impact on the lattice thermal conductivity of both heavily doped p‐type and n‐type semiconductors. However, it is found that this is invalid in most wurtzite semiconductors.

Bioinspired Directional Hydrogel‐Based High‐Performance Flexible Sensor for Multiple Jumping Pattern Detection in Athletic Training

Advanced Science, EarlyView.
This study develops a bioinspired directional hydrogel (BDH) via flow‐induced alignment of polyvinyl alcohol and dispersed carbon nanotubes, enhanced by the immersion of natural moisturizing factors. The BDH exhibits superior mechanical strength, conductivity, and moisture retention, enabling high‐performance flexible sensors for precise motion ...

Water‐Wave Pancharatnam‐Berry Phase Induced by 4D Spin‐Orbit State Evolution

Advanced Science, EarlyView.
The first observation of the Pancharatnam‐Berry (PB) phase in water waves is reported, revealing its extraordinary properties including unbounded phase values, spin‐momentum‐locked unidirectional channels, and a Poincaré hypersphere representation. These findings demonstrate the universality of the PB phase across different wave systems and in higher ...
