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.

Nonstoichiometric Defect Engineering in Mn2+‐Doped MgGa2O4 Persistent Phosphors Toward Enhanced Luminescence and Multimodal Optical Manometry

Advanced Science, EarlyView.
Mg2+ deficiency transforms Mn2+‐doped MgGa2O4 into a multifunctional persistent phosphor, enhancing green emission, thermal stability, and afterglow effect for optical anti‐counterfeiting. Under compression, spectral shifts enable visual pressure sensing with a sensitivity of 5.01 nm GPa−1 over a pressure range up to 30 GPa.

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

Advanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Dual‐Defect‐Engineered Zinc Oxynitride Thin‐Film Transistors Enabling Electrostatic Current Balancing in Geometrically Symmetric Oxide Logic

Advanced Electronic Materials, EarlyView.
Dual‐defect engineering controls subgap states in zinc oxynitride (ZnON) thin‐film transistors, yielding a field‐effect mobility of 26.58 cm2 V−1 s−1. A process‐associated threshold‐voltage shift is repurposed within a dual‐gate depletion‐mode load to electrostatically balance current in a geometrically symmetric NMOS inverter.

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

Advanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

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 ...
