Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

The Potential of Zero Charge: An Interfacial Descriptor Governing Hydrogen Evolution Reaction on Bulk Metal Electrodes

Advanced Science, EarlyView.
This work establishes a dual‐descriptor framework incorporating hydrogen adsorption free energy and potential of zero charge, constructing a corrected 3D HER volcano plot. It reveals that surface charge and interfacial proton concentration jointly govern activity, beyond conventional 2D thermodynamic scaling relations. ABSTRACT While the Sabatier‐based

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

Advanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.
