Multiscale Freestanding Vertically Aligned CNT Heat Sink Enabling Multimodal Heat Dissipation by Conduction, Convection, and Radiation

Advanced Science, EarlyView.
This study demonstrates a vertically aligned CNT (VACNT)‐based heat sink. The nanoporous structure of the VACNT provides a large surface area for convective and radiative exchange, alongside axial conduction, enabling multimodal heat dissipation. Mounted on a CPU, the VACNT with a fin array pattern achieves a steady‐state temperature 6.7°C lower than a

Dynamic Supercooled Crystal–Gels for Ultrafast, Reversible Mechanical Adaptative Materials

Advanced Science, EarlyView.
A dynamic supercooled crystal–gel mimics starfish tissue by storing non‐equilibrium energy in a metastable liquid. A gentle touch triggers templated crystallization, producing a 2596‐fold stiffness increase with negligible volume change. The lattice disintegrates reversibly under humidity or warmth.

Negative Gauge Factor Piezoresistance in Soft Strain and Pressure Sensors: Mechanisms, Materials, and Emerging Applications

Advanced Science, EarlyView.
Negative‐gauge‐factor materials reverse the usual rule of piezoresistive sensing: their resistance falls, rather than rises, under deformation. This review organizes such behavior into four mechanistic classes spanning intrinsic semiconductors, composites, conducting polymers, and engineered architectures.

Anisotropic Nanofiber Architectures for Strain‐Insensitive Pressure Sensing and Stretchable Interconnects

Advanced Electronic Materials, EarlyView.
Electrospun PEDOT/PAAm nanofiber mats exhibit anisotropic electromechanical behavior, maintaining stable resistance under tensile strain while showing pressure‐responsive resistance modulation under vertical loading. This direction‐dependent response highlights their potential as tensile‐stable, pressure‐responsive components for deformable sensing and
