Summary: In this study, the ultrafast thermalization dynamics of temperature fields in Au/Ni film excited by a femtosecond laser double-pulse vortex beam were theoretically investigated. It was proposed that the energy deposition in the layered film can be significantly enhanced by applying the double-pulse vortex beam, leading to vortical thermalization in the Ni layer on a picosecond timescale. The intensified dynamics of the double-pulse vortex beam interacting with the excited state of the film and the energy competitive processes of electron diffusion and electron-phonon coupling were identified as the main causes for this phenomenon. The research also explored the relationship between the electron-phonon coupling period of the film and important laser parameters such as pulse separation and vortex beam fluence.

Summary: Visualization experiments were conducted on microfluidic pore networks to understand the interactions between salt precipitation, corner liquid film flow, and gas-liquid displacement during evaporation. The study revealed two forms of salt precipitation - aggregated polycrystalline structures and large bulk crystals. It was found that gas bubbles could form due to liquid imbibition into aggregated polycrystalline structures. The length of a corner liquid film affected the growth direction of the aggregated polycrystalline structures.

Summary: Hard-to-transfect cells, such as BMSCs, present challenges in intracellular delivery due to vesicle trapping. We found that coating nanoparticles with PDS1 can effectively avoid vesicle trapping in BMSCs and significantly enhance transfection efficiency and osteoblastic differentiation. Mechanistic studies suggest that higher cholesterol content in BMSCs' plasma membranes may contribute to the difficulty of vesicle escape.

Summary: The study prepared a slippery surface with excellent self-cleaning, stability, and self-healing properties, inspired by the Nepenthes plant. The stretchability of the slippery surface is essential for application in flexible sensor surfaces. By using femtosecond laser, an interconnected porous structure was prepared on pre-stretched polydimethylsiloxane, and then infused with lubricant to create the slippery surface. This stretchable slippery surface maintained its performance even under tensile conditions and after multiple stretch cycles, demonstrating remarkable self-cleaning and chemical stability. The femtosecond laser direct writing technique holds promise for stable surfaces in various extreme environmental applications of flexible electronic devices.
