Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron
