A bioinspired artificial compound eye (ACE) is fabricated by femtosecond laser wet etching, soft lithography, and polydimethylsiloxane (PDMS) swelling methods. The resultant ACE sample close-packed with more than 3000 high-quality microlenses on a spherical macrolens over its large viewing angle. trapped silicone oil in the PDMS endows device excellent water repellence anti-fogging ability besi...

Many bioactive products from benthic invertebrates mediating ecological interactions have proved to reduce predation, but their mechanisms of action, and their molecular identities, are usually unknown. It was suggested, yet scarcely investigated, that nutritional quality interferes with defensive metabolites. This means that antifeedants would be less effective when combined with energetically...

Hydrophobicity and oleophobicity are highly desirable properties for materials that are used in a wide range of applications. In this context, poly(tetrafluoroethylene) (teflon) is considered to be the “benchmark” low-surfacefree-energy material as it combines water repellence with other desirable properties. Unfortunately, the use of teflon comes with certain disadvantages, such as those resul...

Abstract Smart surfaces with externally controlled wettability patterns are ubiquitous building blocks for micro-/nanofluidic and lab-on-chip devices, among others. We develop hierarchical of ZnO nanorods grown on laser-microstructured silicon reversible photo-induced heat-induced wettability. The as-prepared superhydrophilic, very low water contact angles (~ 10°), transition to a wetting state...
