Dual‐Sabatier Optima: How Reaction Mechanism Determines Activity Volcano Map of Dual‐Atom Catalysts for Oxygen Reduction Reaction

open access: yesAngewandte Chemie, EarlyView.
Dual‐atom catalysts (DACs) for oxygen reduction reaction (ORR), where the dissociative mechanism dominates, show a dual‐Sabatier optima volcano map, diverging from the classical single‐peak volcano of the associative mechanism. Potential‐dependent microkinetic modeling and interpretable machine learning rationalize experimental data and provide design ...

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

open access: yesAdvanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Quantitative Photo‐Reforming of Biomass to CO Spurred by In Situ Protonation of Carbon Dioxide Radical Anions

open access: yesAngewandte Chemie, EarlyView.
A “two‐in‐one” photoreduction strategy enabled by electron‐rich yolk Cd species both remote from and adjacent to sulfur vacancies is delivered to be ultraselective for the reduction of O2 and •CO2− in situ formed on the shell Bi2S3 composition (hole) by water oxidation and oxidative C–C cleavage of various biomass organic acids, furnishing CO with > 99%

Tandem Neural Network Rapidly Solves Multivalued Inverse Problems: Application to Oxide‐Semiconductor Characterization

open access: yesAdvanced Intelligent Systems, EarlyView.
A tandem neural network directly solves the multivalued inverse problem of extracting semiconductor parameters from transistor measurements. Trained on only 1000 simulations, the network infers six material parameters (e.g., defect states, carrier concentration, mobility) in under 1 ms, demonstrating a broadly applicable framework for semiconductor ...
