Scanning Error Compensation in Ground-Based ArcSAR Monitoring
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingGround-based arc-scanning synthetic aperture radar (GB-ArcSAR) can perform 360° scanning and has a large field of view. Based on the differential interferometry technique, GB-ArcSAR can be utilized to measure the surface deformation.

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3
Advanced Functional Materials, EarlyView.Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Advanced Functional Materials, EarlyView.In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.

A Tracer Diffusion Study of Diverse Photo‐Ionic Phenomena in Strontium Titanate
Advanced Functional Materials, EarlyView.Two strong interfacial photo‐ionic effects are demonstrated for the model system SrTiO3 through the application of isotope exchange experiments: UV illumination is found to enhance the oxygen surface exchange coefficient by several orders of magnitude and to depress the surface space‐charge potential substantially.
