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.

Zr Incorporation Into Lithium Nickel Oxides: Bulk or Surface Substitution?

Advanced Science, EarlyView.
Mechanism of Zr incorporation into lithium nickel oxide (LNO) cathodes is studied from atomistic to macroscale. Zr doping enhances cyclability of Li‐ion batteries with LNO via bulk, interface, and grain boundary optimization leading to structural integrity at atomistic‐ and micro‐scale of secondary particle aggregates.

PARTIAL REGULARITY FOR HIGHER ORDER VARIATIONAL PROBLEMS UNDER ANISOTROPIC GROWTH CONDITIONS

, 2007
We prove a partial regularity result for local minimizers u: Rn ⊃ Ω → RM of the variational integral J(u,Ω) = Ω f(∇ku) dx, where k is any integer and f is a strictly convex integrand of anisotropic (p, q)-growth with exponents satisfying the condition q &

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

Advanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Epsilon-regularity for almost-minimizers of anisotropic free interface problem with Hölder dependence on the position

We establish an ε-regularity result for almost-minimizers of a class of variational problems involving both bulk and interface energies. The bulk energy is of Dirichlet type.

A Closed‐Loop Direct Recycling Process for Prussian White From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A closed‐loop direct recycling route for Prussian White sodium‐ion battery cathodes is demonstrated. Ice‐stripped scrap and end‐of‐life electrodes are regenerated via low‐temperature aqueous resodiation (80°C), restoring sodium content, Fe2+ redox chemistry, and structural integrity.

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Chemical Rounding Suppresses Morphology‐Induced Interfacial Losses in Perovskite–Silicon Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Chemical rounding transforms irregular submicron silicon textures into more favorable interfaces for perovskite–silicon tandems. Suppressed local epitaxial ordering improves bottom‐cell passivation, while the top‐cell stack exhibits a higher and more spatially uniform quasi‐Fermi‐level splitting, enabling monolithic tandem solar cells with an ...

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.
