Dragonflies are one of the few groups to rest with the wings fully outstretched, the others having a basal hinge that allows the wings to be drawn automatically towards the body when they stop flying. We also sketch the relation between multiple zeta values and periods of moduli spaces of marked curves. Fetching data from CrossRef. 80, Wetting characteristics of beetle wing surfaces, Morphologies of beetle wings. Since these improvements are obtained solely from the defect distribution within a single material, the findings of this work could improve the failure characteristics of a broad range of printed materials (metals, ceramics, polymers, and composites).

Then we prove that there is no embedding of the phenomenologically symmetric geometry of two sets of rank (n + 1, n + 2) in the phenomenologically symmetric geometry of two sets of rank (n +1, n +3). For convenience and protection it is imperative that their delicate membranes can be safely stowed away when not in use. (b) Photographs of the, hydrogel corresponding to different humidity. We determined the relationship between composition and mechanical properties of elytra (modified forewings that are composed primarily of highly sclerotized dorsal and less sclerotized ventral cuticles) from the beetles Tribolium castaneum (red flour beetle) and Tenebrio molitor (yellow mealworm). In this paper, the structure, mechanical properties and their relationship to function of beetle wings are discussed. 269–273. Those are, closely related to the microstructures both on the surface and, on the inside. been produced using electrospun nanofiber webs.

In this paper, the structure, mechanical properties and their relationship to function of beetle wings are discussed. This review includes the smart designs of structural materials and the functional device architectures inspired by biology, which have opened new avenues to develop high-performance flexible tactile sensors and advanced artificial sensory systems.

Based on the geometric parameters of the nanopillars at the hydrophilic and hydrophobic regions on the cicada wing, two wetting models are developed for elucidating the mechanism for the gradient wetting behavior. Structured color in nature is controlled by nano‐ and micro‐structured interfaces giving rise to a photonic bandgap. A beetle’s functional wings, which allow flying, are the hind wings.

Beetle wings are composed of a forewing (also known as elytron) and a hind wing. 2b). Details of this common wing folding mechanism can be found in textbooks of entomology (e.g. Folding may sometimes occur along the flexion lines. Many holes (or, pore canals) in the cuticle have been reported (Fig. The structure parameters as mechanisms bodies that allow wings of various beetle species to … In order to improve the flight performance of collapsible aircrafts, a novel mechanism of bionic foldable wings of beetle is designed based on the four-plate mechanism theory.
