Wafer‐Scale Synthesis of Topological Insulator Sb2Te3 Thin Films
Advanced Materials Interfaces, EarlyView.This work demonstrates how the topologically protected conduction in Sb2Te3 thin films can be extended from few‐mm2 samples’ area up to larger areas of several cm2 Si(111) wafers. The reported findings represent a breakthrough for the future technology scale‐up of topological insulators for applications such as spintronics, thermoelectrics, and quantum

Interstellar scintillation is an indicator of astrometric stability [PDF]
, 2013 We examine the relationship between astrometric stability and astrophysical properties in flat-spectrum radio-loud quasars making up the celestial reference frame. We use position determinations from geodetic VLBI measurements, and develop a new metric for source position stability.

Nanohybrid of Silver‐MXene: A Promising Sorbent for Iodine Gas Capture from Nuclear Waste
Advanced Materials Interfaces, EarlyView.Silver‐MXene (Ag‐Ti3C2Tx) nanohybrids effectively captured iodine gas at 150 °C, with Ag nanoparticles loaded onto MXene via silver nitrate reduction. Upon exposure to iodine gas, silver iodide forms, confirming successful adsorption. Ag‐Ti3C2Tx shows superior iodine uptake (946 mg g−1) compared to conventional sorbents, demonstrating its potential as ...

From Photo‐Damage to Self‐Healing in Thin Film Pb‐Iodide Perovskites: Action at a Distance
Advanced Optical Materials, EarlyView.Fluorescence imaging uncovers pronounced spatial and temporal changes in photoluminescence of halide perovskite films following laser‐induced damage. Modifications spatially extend well beyond the illuminated region and evolve over distinct time scales ranging from seconds to many hours, revealing material‐specific self‐healing pathways. These findings
