The Effects of Microenvironment on Cells and The Application of Bionics in Tissue Engineering Scaffolds

Microenvironment effects proliferation, migration and functions of cells. The factors of microenvironment that effect fate of cells include interactions between cells and extracellular matrix,soluble signal molecules,anoxia and nutrition. To prepare engineering tissue scaffold need to simulate the cells microenvironment furthest following the bionics theory so that the scaffold can be used in studies of cell behaviour and clinical therapy. Comprehensive understanding the effects factors of microenvironment on cells played an important role on tissue engineering scaffold preparation,and the studies about tissue engineering scaffold also promoted the knowledge about microenvironment effect on cells.

Erosion-Resistant Surfaces Inspired by Tamarisk

Tamarisk, a plant that thrives in arid and semi-arid regions, has adapted to blustery conditions by evolving extremely effective and robust anti-erosion surface patterns. However, the details of these unique properties and their structural basis are still unexplored. In this paper, we demonstrate that the tamarisk surface only suffers minor scratches under wind–sand mixture erosion. The results show that the anti-erosion property of bionic sample, inspired by tamarisk surface with different surface morphologies, can be attributed to the flow rotating in the grooves that reduces the particle impact speed. Furthermore, the simulation and experiment on the erosion wear behavior of the bionic samples and bionic centrifugal fan blades show that the bionic surface with V-type groove exhibits the best erosion resistance. The bionic surface on centrifugal fan blades with optimum parameters can effectively improve anti-erosion property by 28.97%. This paper show more opportunities for bionic application in improving the anti-erosion performance of moving parts that work under dirt and sand particle environment, such as helicopter rotor blades, airplane propellers, rocket motor nozzles, and pipes that regularly wear out from erosion.

A Method for Quantitative Analysis of Geometrical Structure of Animal Organs in Meso-Scale: The Dung Beetle Foreleg End Tooth as a Case Example

The geometrical shapes of some animal organs have distinguished functions and properties that can provide useful information for bionic engineering applications. Hence, it is necessary to quantitatively measure the geometrical structure of those animal organs. However, some of the animal organs are tiny, complex and in the Meso-scale (0.1~10 mm). Their potential bionic application requires an accurate and efficient method to quantitatively analysis of their geometrical shapes. But existing methods are difficult and inefficient to quantitatively analysis. Yet, it was found that MATLAB image processing and computer vision technique can be advantageously exploited to obtain outer margin geometrical information from stereomicroscopy photograph. In this work, based on MATLAB, a program was designed and a method was proposed that specified for extract meso-scale animal organ outer margin contour points. The procedure for obtaining quantified geometrical information can be conclude as that stereomicroscope image of bionic object animal organ was prepared, the image to reduce noise interference was processed, the outer edge contour points was detected, and the points x and y coordinates data to computer database was stored. The foreleg of dung beetle Copris ochus Motschulsky, which is with special tooth-like structure for burrowing, the height of the end tooth is only around 1 mm and the width is about 0.5 mm, supported by this method, the outer edge profile of the foreleg end tooth was extracted from stereomicroscopy image with 669 × 727 pixels, about 1500 outer edge contour points was obtained, points x and y coordinates data were inputted to computer database for further analysis. This method is efficient, accurate and easy to adapt to quantitatively analysis of geometrical characteristic features of other animal organs in meso-scale.

Robust adhesion of flower-like few-layer graphene nanoclusters

Nanostructured surface possessing ultrahigh adhesion like “gecko foot” or “rose petal” can offer more opportunities for bionic application. We grow flower-like few-layer graphene on silicon nanocone arrays to form graphene nanoclusters, showing robust adhesion. Their contact angle (CA) is 164° with a hysteresis CA of 155° and adhesive force for a 5 μL water droplet is about 254 μN that is far larger than present reported results. We bring experimental evidences that this great adhesion depends on large-area plentiful edges of graphene nanosheets tuned by conical nanostructure and intrinsic wetting features of graphene. Such new hierarchical few-layer graphene nanostructure provides a feasible strategy to understand the ultra-adhesive mechanism of the “gecko effect” or “rose effect” and enhance the wettability of graphene for many practical applications.

Application of Bionics in Antenna Radar Cross Section Reduction

Bionics principle is applied to antenna radar cross section (RCS) reduction in this letter for the first time. To authenticate the method, a novel bionic ultrawideband (UWB) antenna is proposed by use of a model of insect tentacle. Its UWB-related radiation characteristics are simulated and experimentally verified. Monostatic RCS of an insect tentacle antenna (ITA) terminated with three different loads are studied and compared with that of a common printed circular-disc monopole antenna (PCDMA). The results show that compared to the reference antenna, the novel bionic antenna has lower RCS and favorable radiation performances. Hence, applying bionics principle to antenna RCS reduction is feasible, which will serve as a good candidate for the future design of antennas with a requirement of RCS control.
