Ultrashort‐Pulsed Laser Diffusion Enhancement in Liquids for Cold Extraction of Coffee in an Analytically Validated Low‐Fluence Regime

open access: yesAdvanced Photonics Research, EarlyView.
In this article, pulsed laser diffusion enhancement in liquids as an analytically validated laser extraction in liquids method of coffee suspensions in a defined low fluence window is presented. The results confirm the generation of a unique aroma profile and reduced acidity, which is neither attributed to changes in the specific surface area nor ...

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

open access: yesAdvanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

High‐Asymmetry Metasurface: A New Solution for Terahertz Resonance via Active Learning‐Augmented Diffusion Model

open access: yesAdvanced Science, EarlyView.
A prior knowledge‐guided diffusion model augmented by physics‐constrained active learning is developed to design high‐asymmetry terahertz metamaterials. Trained on only a small set of classical structures, the model efficiently generates new high‐metrics designs.

Photocatalytic Activity of Ionic Carbon Nitrides is Governed by Cation‐Modulated Dark Exciton Dynamics

open access: yesAdvanced Science, EarlyView.
This study establishes a direct link between photocatalytic activity, spectroscopic properties, and theoretical analysis of structural effects on exciton behavior in ionic carbon nitrides with different cations. The exciton lifetimes and photocatalytic activity are shown to be primarily related to different dark exciton dynamics governed by changes in ...
