A Homeostatic Photonic Device Integrating Vapor‐Regulated Thermo‐Optical Feedback Mechanisms
An inorganic homeostatic photonic device is designed to autonomously regulate light, temperature, and vapor sorption through integrated positive and negative feedback mechanisms at multiple wavelengths. The device uses a graded mesoporous 1D photonic crystal coupled with a photothermal layer.

Optimizing Wealth by a Game within Cellular Automata [PDF]
The objective is to find a Cellular Automata (CA) rule that can evolve 2D patterns that are optimal with respect to a global fitness function. The global fitness is defined as the sum of local computed utilities. A utility or value function computes a score depending on the states in the local neighborhood.

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.
