RVSNUpy: A Python Package for Spectroscopic Redshift Measurement Based on Cross Correlation
The Astronomical JournalWe introduce RVSNUpy , a new Python package designed to measure spectroscopic redshifts. Based on inverse-variance-weighted cross correlation, RVSNUpy determines redshifts by comparing observed spectra with various rest-frame template spectra.

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach
Advanced Materials, EarlyView.Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Advanced Materials, EarlyView.A fluorine‐containing hyperbranched polymer is developed to guide oriented crystallization and construct a cross‐linked hydrophobic network, enabling the formation of high‐quality perovskite films with enhanced environmental stability. The resulting devices deliver a PCE of 26.05% (0.04 cm2) and 22.43% (16.1 cm2), while maintaining 97% of their initial

Advanced Materials, EarlyView.This study reports the first discovery of intrinsic mechanoluminescence in undoped AlN crystals, accompanied by pronounced photoluminescence and persistent luminescence. It further demonstrates a defect‐emission–driven multifunctional optical sensing platform for force, pressure, and temperature detection, achieving exceptional sensitivities.

Redshift Drift in Relativistic N-Body Simulations
The Open Journal of AstrophysicsThe cosmological redshift drift promises to be the first observable directly measuring the evolution of the cosmic expansion rate and should be detectable with upcoming surveys by the Square Kilometre Array and the Extremely Large Telescope.

Advanced Materials, EarlyView.By tracking bulk carrier diffusion both vertically and laterally, this study links photoluminescence behavior to crystal quality in CsPbBr3 γ‐ray detectors. Vertical diffusion governs spectral redshift, with high‐quality crystals exhibiting superior transport, while two‐photon microscopy reveals microscale defects that hinder diffusion in low‐quality ...
