The First Polarimetric View on Quasiperiodic Oscillations in a Black Hole X-Ray Binary
The Astrophysical Journal LettersWe present the first polarimetric analysis of quasiperiodic oscillations (QPOs) in a black hole binary utilizing IXPE data. Our study focuses on Swift J1727.8–1613, which experienced a massive outburst that was observed by various telescopes across ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

X-ray Gyrations of Eta Carinae, or, Is Presence of Evidence Evidence of Presence? [PDF]
arXiv, 2004 We review the properties of the variable X-ray emission from the extremely massive star Eta Carinae concentrating on the last X-ray minimum, and briefly consider the possible role of a binary companion star on the observational properties of the system.

Advanced Materials, EarlyView.Biomechanical‐to‐electrical energy conversion devices are uniquely suited for self‐driven physiological information monitoring and powering human–computer interaction systems. These devices based on micro‐/nanoarchitectured inorganic dielectric materials (MNIDMs) have shown ultrahigh electromechanical performance and thus great potential for practical ...

Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells
Advanced Materials, EarlyView.A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Advanced Materials, EarlyView.A natural binary electrolyte additive is designed to achieve an enhanced interfacial molecule adsorption layer for Zn protection via reshaping the electric double‐layer structure. Consequently, the hydrogen evolution reaction is suppressed and a robust inorganic solid electrolyte interphase is constructed for dendrite‐free Zn plating.
