Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films
Advanced Functional Materials, EarlyView.The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

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,

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion
Advanced Materials, EarlyView.Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

Advanced Materials, EarlyView.A machine learning‐driven microkinetic framework, based on graph neural networks is developed, for screening non‐noble catalysts in NH2OH hydrogenation. This approach enables the discovery of efficient catalysts for plasma–electrochemical ammonia synthesis directly from air under ambient conditions. CuMnSb is identified as a top‐performing, sustainable
