Inorganic Dielectric Materials Coupling Micro‐/Nanoarchitectures for State‐of‐the‐Art Biomechanical‐to‐Electrical Energy Conversion Devices

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 ...

The First Polarimetric View on Quasiperiodic Oscillations in a Black Hole X-Ray Binary

The Astrophysical Journal Letters
We 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 ...

The Influence of Thermonuclear Bursts on Polar Caps of the Accreting X-Ray Millisecond Pulsar MAXI J1816-195

The Astrophysical Journal Letters
We report accretion-powered pulsations for the first time during thermonuclear bursts in hard X-rays, which were observed with Insight-HXMT in 2022 during the outburst of the accreting X-ray millisecond pulsar MAXI J1816-195.

Unveiling Energy Loss Mechanisms to Empower Ternary Organic Solar Cells with over 20% Efficiency: A Systematic Oligomeric Approach

Advanced Materials, EarlyView.
This study designs modular oligomeric donors (5BDD, 5BDD‐F, 5BDT‐F, 5BDT‐Cl) for ternary OSCs, achieving PCEs >20%. By systematically tuning energy levels, we reveal material compatibility, not HOMO alignment, drive VOC enhancement, suppress ACQ and reduce energy loss, offering new design principles for high‐efficiency OSCs.
