Photometric and Spectroscopic Investigations of Three Large Amplitude Contact Binaries
The Astronomical JournalAbstract We performed photometric and spectroscopic studies of three large amplitude contact binaries: NSVS 2418361, ATLAS J057.1170+31.2384, and NSVS 7377875. The amplitudes of these three systems’ light curves are more than 0.7 mag. We analyzed the light curves using the Wilson–Devinney code to yield physical parameters.

Optical variability and narrow-line region kinematics in Type 2 active galactic nuclei
Astronomy & AstrophysicsContext. Optical variability in Type 2 active galactic nuclei (AGNs) is rarely explored because the direct accretion-disc continuum is obscured by circumnuclear dust.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Advanced Functional Materials, EarlyView.Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
