A New Framework for Active Galactic Nucleus Accretion and Jet Feedback in Numerical Simulations
The Astrophysical Journal Supplement SeriesAccurate modeling of active galactic nucleus (AGN) feedback, especially due to relativistic jets, is crucial for understanding the cool-core problem in galaxy clusters.

Evaluating the Resistance of Bifacial Perovskite Photodetectors to Xenon Ion Irradiation
Advanced Science, EarlyView.Bifacial perovskite photodetectors maintain high efficiency and stability after 231 MeV xenon ion irradiation. Key photodetector parameters remain nearly unchanged at low fluence (1010 nucleons cm−2) and show only moderate degradation at high fluence (1011 nucleons cm−2), highlighting their strong radiation tolerance and suitability for optoelectronic ...

Ultra-long-period Cepheids as Standard Candles from Gaia to Rubin-LSST
The Astrophysical Journal Supplement SeriesAn analysis of the properties of ultra-long-period Cepheids (ULPs) could significantly contribute to understanding the Hubble constant tension, e.g., the current discrepancy between determinations based on local distance indicators and those relying on ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer
Advanced Electronic Materials, Volume 11, Issue 6, May 2025.A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Advanced Energy Materials, EarlyView.Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
