“…In all cases, the mouthparts-whose main function is to chew-must be stiffer, harder, stronger and more resistant than the food to prevent breakage, wear or deformation. Similarly, it must have a good cutting tool [16,17]. However, insect mouthparts are not always as simple as most metal-cutting tools.…”

Research Highlights: The novelty of this study is the deep analysis of the morphologic, geometric and mechanical performance of longhorn beetle larvae mouthparts. Furthermore, a metal nano identification of jaw reinforced parts was made. Background and Objectives: Analysis of insect mechanical properties has shown an important application in the develop of bionic technologies such as new materials, industrial machines and structural concepts. This study aims to determine the mechanical and geometric properties of longhorn beetle (Stromatium unicolor Olivier 1795) larvae mouthparts to improve the development of innovative cutting tools. In addition, this study obtains a nano identification of metals in the cuticle of the mouthparts, which will enable the development of new nontoxic and sustainable preservation agents against xylophagous insects based on nanoparticles. Materials and Methods: five third-larval-stage samples of Stromatium unicolor were used to study its mandible morphologic, geometric and mechanical properties. To this end, mouthparts were analyzed by several microscopic techniques using a scanning electron microscope, a stereomicroscope and an optical microscope. Composition analysis was performed using with two Analytical-Inca X-ray detectors, dispersive energy spectroscopy and dispersive wavelength spectroscopy. Results: The main geometric parameters of the insect jaw are the edge angle (β = 77.3°), maximum path depth of the insect (120 μm), length (800 µm) and mouthpart movement, which were identified and measured. The chemical analysis results of the jaw tissues shows the presence of zinc and manganese. Conclusions: The geometry and angles of the mouthparts can be applied in the fabrication of bionic self-sharpening cutting tools. Molecular compounds that form the reinforcing elements in the jaws can be used to develop wood preservatives based on nanometals and metal absorption and metabolism inhibitors.

The influence of a magnetic field on electrodeposition of nickel films over polymeric substrates, which renders flexible membranes with a permanent magnet layer, has been studied. Samples of membranes with nickel deposited by electroplating in presence and absence of magnetic field are compared. The electroplated layer is deposited over an electroless contact layer, after a wet pre-treatment to improve adherence. Mechanical and magnetic properties of the samples were measured as function of process parameters. Experimental results confirm that the magnetic field has a positive impact over properties of deposited films. Pre-treatment using different process times influences uniformity and adherence of the deposited films. Results show also that films electroplated in presence of magnetic field outperformed those deposited in its absence, with enhanced maximum energy product and reduced surface roughness. On the other hand, films electroplated in presence of magnetic field tend to be less resistant to fracture during flexure tests.Nucleation.-The seed layer is obtained by sensitizing the polymer with an acid stannous chloride solution (1 g/l), then activating it with palladium chloride solution (0.25 g/l). The stannous ions (Sn 2þ ) absorbed on the surface reduce the palladium ions (Pd 2þ ), by the reaction (1). The palladium metal atoms form clusters and the seed layer which catalyzes the electroless nickel deposition. 35,36 z

Bionic design is a new method in engineering design. The mouthparts especially for the chewing ones of the insects are discussed in this article. To improve the tool life and cutting properties are always the critical for the cutting tool design aim. The foreground of cutting tool design is discussed using the mouthpart of insect as bionic design object. The basic structure of the chewing mouthpart, type of mandibles, geometry, hardness, and element contained, moving mechanism and so on will be described. The research can also make direction at new tool material and tool geometry parameter design.
