Summary: In this study, carbon particles were adsorbed on the surface of stainless steel meshes (SSMs) to form a thin hydrophobic coating, and a rough structure was then constructed through chemical vapor deposition and high temperature calcination, with the resultant SSM surface wrapped with uniform silica coating possessing superoleophobicity-underwater. The prepared SSMs exhibited superhydrophilicity in air and superoleophobicity-underwater. They showed high separation efficiency (above 98.8%) and separation flux (46,300 L·m(-2)·h(-1)) for oil/water mixtures. Immersion in different solutions did not significantly affect their separation efficiency (above 97.3%), and further immersion in dopamine and octadecylamine solutions transformed the SSMs into superhydrophobic SSMs with reverse surface wettability, which also exhibited good separation efficiency and separation flux for oil/water separation.

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: We theoretically investigate the spatial-temporal dynamics of extraordinary optical transmission (EOT) in a two-slit plasmonic antenna irradiated by femtosecond laser dual-beam. The dynamic interference of femtosecond laser dual-beam with transiently excited surface plasmon polariton waves is proposed to characterize the specific spatial-temporal evolutions of EOT. Our study reveals that the dynamic EOT can be flexibly switched and its symmetry can be tunable by manipulating the phase correlation of the crossed femtosecond laser dual-beam. Furthermore, we obtain the unobserved traits of symmetry-broken transient spectra of EOT from the respective up- and down-slit of the antenna.
