A Biomimetic Solvatochromic Chip With Optimized Chemical Diversity for On‐Site Liquid Identification

Advanced Science, EarlyView.
A compact biomimetic photonic‐gustatory chip uses Hansen‐solubility‐parameter‐guided solvatochromic disks to create distinct color patterns in organic liquids. An optimized four‐disk array distinguishes solvent types, ratios, homologues, isomers, and alcoholic beverages. Coupled with smartphone imaging and deep learning, it identifies 80 liquid classes

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
