Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

The necessity of construct and external validity for deductive causal inference
Journal of Causal InferenceThe Credibility Revolution advances internally valid research designs intended to identify causal effects from quantitative data. The ensuing emphasis on internal validity, however, has enabled a neglect of construct and external validity.

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Flow‐Induced Microdomain Alignment During Block Copolymer Graphoepitaxy
Advanced Materials, EarlyView.This study investigates block copolymer flow on topographical templates during solvent vapor annealing and how flow affects the orientation of self‐assembled microdomains. The temporal mapping between flows and microdomain orientation reveals an intriguing dependence of flow‐induced microdomain alignment on film thickness and trench depth, and provides

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid
Advanced Materials, EarlyView.This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional

Advanced Materials, EarlyView.Aggregation‐induced emission strategy is first used to overcome aggregation‐caused quenching in Y‐series acceptors. By integrating tetraphenylethylene, the dTPE exhibits three‐fold PLQY enhancement and significantly suppressed non‐radiative energy loss. An ultra‐low Eloss of 0.130 eV and a record VOC of 0.93 V are achieved, resulting in a PCE over 20.5%

Advanced Materials, EarlyView.A solvent engineering strategy using polar polymers is introduced to regulate perovskite crystallization dynamics in solar cells. Strongly polarized fluorinated groups stabilize the intermediate phase and control solvent exfoliation, leading to high‐quality films with suppressed defects.
