Remarkable surface wettability transition occurs with an inducement of ultraviolet (UV) for aligned ZnO nanorod films. The inorganic oxide films, which show super-hydrophobicity (left), become super-hydrophilic (right) when exposed to UV illumination. After the films are placed in the dark, the wettability evolves back to super-hydrophobicity. This reversible effect is ascribed to the cooperati...

Super-resolution microscopy allows biological systems to be studied at the nanoscale, but has been restricted to providing only positional information. Here, we show that it is possible to perform multi-dimensional super-resolution imaging to determine both the position and the environmental properties of single-molecule fluorescent emitters. The method presented here exploits the solvatochromi...

this article describes an accurate subpico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both mems/nems and cryogenic technology applications. the mems/nems are described as either two gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of either parallel photonic cry...

Superhydrophobic coating with applicable transmittance was synthesized by simple UV-curable method which likely suitable for large-scale production. The super-hydrophobicity derived from the component containing modified polyhedral oligomeric silsesquioxanes chosen low free energy and potential to form hierarchical structure. adhesion could reach highest level strip tape peel test. Compared UV-...

In this paper, bio-inspired PDMS films with different hierarchical microstructures were designed and tunable adhesive super-hydrophobicity was achieved on these films. The adhesive forces between a water droplet and the PDMS film can be adjusted from extremely low (about 8.3 μN) to very high (about 57 μN), and the tunable effect can be ascribed to different wetting states for the water droplets...
