Aiming at the lightweight filler particles with good dielectric properties in the composites, helical Spirulina platensis were chosen as templates to produce microscopic helical soft-core filler particles by an electroless deposition technique. The morphology and appearance of the coated Spirulina…

From the view of bionic, optimizing and engineering the corrugated bionic needle with polynomial regression. The results showed that; the width of the ripple with quadratic effect plays a major role in reducing resistance; the impact of non-smooth structure’s spacing…

Swordfish is the fastest fish in the world, which can reach a high speed of 110km/h. Depending on the swing of the caudal fin, swordfish gets the power of swimming. The caudal fin of the swordfish shows crescent and wide…

As one of the most important chemical reactions on the earth, the photosynthetic reaction has gained much attention. For example, foliage and algae possess superior abilities to harvest luminous energy from sunlight in photosynthetic reactions by capturing lights with the…

Bionic non-smooth structures on the bodies of revolution had characteristic of drag reduction. In this paper, oil flow visualization test were made in low speed wind tunnel between two bionic non-smooth surface models and smooth surface model. The results show…

The author aimed to explore the application of biological tactile in fast non-destructive meat freshness detection. Used WDW-20 electronic universal testing machine, surveyed chicken, pork and beef the pressure characteristic curves, analysed respectively the relationship between the pressure characteristic curve…

This paper extracts the frigate bird’s leading edge contour by CATIA on the basis of the obverse and side pictures when frigate bird glides. Then three bionic wingspans of bending update, forward and integrating the two are built combining NACA…

Nanoparticles filling is one of the most effective methods to build the micro-nano structure. In this paper, the composite coatings containing Fe3O4 nanoparticles were prepared from fluorinated silicon polymer by in-situ polymerization. FT-IR was used to characterize the structure of…

The hardness of typical plant leaves surfaces was investigated and analyzed by nano-hardness tester. Results show that the mechanical character of varied texture and varied surface morphologies shows regularity. The hardness of coriaceous fresh leaves (Bambusa phyllostachys pubescens etc.) and…

The structure, geometrical shape and material are the three main parts of the prostheses. This research focuses on the geometrical shape analysis. The geometrical shape of human natural femoral head is similar to the ellipse, but, the artificial femoral head…
