Distance to the Galactic Center 7′ Halo from H I Absorption
The Astrophysical JournalUsing archival data, we have made an H I absorption study of the 7 ${}^{{\prime} }$ halo surrounding the Sgr A complex, observed toward the Galactic center (GC) region. We find strong H I absorption near velocities of −53 km s ^−1 , which is due to the 3

Quantitative Stain Mapping in X‐Ray Virtual Histology
Advanced Science, EarlyView.Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi
Advanced Science, EarlyView.Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

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.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC
Advanced Electronic Materials, EarlyView.A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.
