Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering

Advanced Materials Interfaces, EarlyView.
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

The Behaviors of Ionospheric Scintillations Around Different Types of Nightside Auroral Boundaries Seen at the Chinese Yellow River Station, Svalbard

Frontiers in Astronomy and Space Sciences, 2018
Dynamical nightside auroral structures are often observed by the all sky imagers (ASI) at the Chinese Yellow River Station (CYRS) at Ny-Ålesund, Svalbard, located in the polar cap near poleward edge of the nightside auroral oval.

Scintillation Increase Induced by Focusing (Invited)

Photonics, 2023
We show that the focusing of a random electromagnetic beam by a lens gives rise to a scintillation index at the geometrical focus that generally differs from that of the incident beam.
