Summary: In this study, an in situ transmission electron microscopy (TEM) heating system was used to investigate the morphological changes of cubic Ag nanoparticles (NPs) and Ag-based core-shell structures induced by sublimation, as well as the influence of shell coverage on thermal stability. It was found that large Ag NPs (>50 nm) showed a three-stage sublimation-induced morphological change, while small Ag NPs (<30 nm) showed a uniform sublimation. The sublimation process of core-shell NPs started at stage II, and the thermal stability was enhanced by carbon shell passivation.

Summary: This article investigates the nonequilibrium dynamics of charge-density-wave (CDW) melting in van der Waals (vdW) heterostructures using real-time time-dependent density functional theory coupled to molecular dynamics. The study finds that despite fast and sufficient charge transfer, the electronic excitation of vdW heterostructures does not result in nonthermal CDW transition. Instead, the TaS2 lattice is heated by carrier-lattice scattering, leading to thermal CDW melting at high ionic temperatures.

Summary: Time-resolved X-ray scattering was used to demonstrate the ultrafast 300 ps topological phase transition to a skyrmionic phase, mediated by the formation of a transient topological fluctuation state. The emergence of an extended topological phase containing many magnetic skyrmions was observed within picoseconds, with the nucleation process mediated by the transient topological fluctuation state induced by a time-reversal symmetry-breaking perpendicular magnetic field.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
