The deployable hind wings of Coleoptera are highly specialized for their flight. The veins of Asian ladybird beetle (Harmonia axyridis) hind wings play a role in its flight. This paper investigates the structural morphology of veins of hind wing in H. axyridis. Additionally, considering the blood in veins, the total mass, and mass distribution of hind wings are studied. The results shown that the variation trend of mass result of the left and right hind wings are almost consistent with the difference of body weight, and the polynomial fit of the mass of left wings (m1), the mass of right wings (m2) and the body mass of H. axyridis (M) are polynomial functions, and the trends of two polynomial functions are similar. The tensile test results are proved that the hind wing of H. axyridis is a high toughness composites due to the veins’ network structure. The light-mass and high-strength vein of deployable hind wings of H. axyridis will be helpful to design biomimetic deployable micro air vehicle (MAV).

The ultrasonic vibration has increasing implementation in metal machining as an assisted method. It adds high frequency vibration with low amplitude to the workpiece or the cutting tool and it has been verified to have the great potential on cutting force reduction, surface quality improvement, tool wear decrease and so on. This paper applied the ultrasonic vibration to the micro-holes drilling of 30CrNiMo8. In order to identify the performance of the combination, an ultrasonic machine tool with the vibration in the feed direction was designed and assembled. The spindle speed and feed rate and were taken as the controlled variables and a series of experiments were carried out. The results indicated that the ultrasonic assisted micro-holes drilling transformed the drilling process and the mechanism of the chip formation, which noticeably suppressed the exit burrs and ensured the dimensional accuracy and the surface roughness of the micro-holes.

An inertial piezoelectric actuator with large angular velocity and high resolution equipped with various combinations of asymmetrical clamping structures and a bias unit is presented. Two control types are constructed as types A and B. Simulation experiments are conducted to explore the angular displacement and velocity characteristics. The first-order natural frequency by simulation is 16.666 and 17.379 Hz for types A and B, respectively, which agrees with the experiment results of 13.828 and 14.141 Hz. Furthermore, for type A, compared with the characteristics of the actuator that has a sole asymmetrical clamping structure, angular velocity is improved to approximately 6.90 times from 18.88 mrad/s to 130.23 mrad/s at 50 V and 7 Hz. For type B, the resolution is enhanced to 2.85 times from 7.98 μrad to 2.80 μrad under a square signal of 20 V and 1 Hz and offset distance of −22 mm. Thus, type A can improve angular velocity and type B can enhance resolution.

Here, we introduce electrolithography, which is a recently developed lithography technique. Upon passage of electric current through a pointy cathode electrode placed on Cr film leads to formation and liquefaction of a Cr compound, which then flows away from the cathode in a radially symmetric fashion, thereby removing the Cr layer. If the pointy electrode, akin to a stylus, is traversed along a path, a trench will be patterned in the Cr film, which can then be transferred to other materials. Firstly, we describe the process of electrolithography and then we discuss the effects of the force applied on the stylus and the polymer layer placed in between substrate and Cr film on this lithography process. Finally, we discuss future prospects of electrolithography.

We demonstrated a label-free electrochemical biosensor for detection of cell surface receptor (CSR) based on ligand-receptor interaction between its corresponding bioactive substance (BS) and the cell membrane receptor. The biosensor was fabricated through layer-by-layer (LBL) deposition method using chitosan (Chi) and bioactive substance conjugated multi-walled carbon nanotubes (MWCNTs-BS). Our optimized CSR detection approach using the designer biosensor yielded a linear detection range wildly from 1 ng/mL to 10,000 ng/mL, achieving the limit of detection (LOD) of 0.106 ng/mL.

Gaussian-based optical networks-on-chips (ONoCs) have significant topological advantages over mesh and torus networks in terms of network diameter and average jump distance. However, the crosstalk noise that accumulates in the network can cause severe performance degradation and limit the scalability of the network. Therefore, this paper analyzes the three aspects of basic optical elements, optical router and network, and proposes a Gaussian-based ONoCs worst-case crosstalk noise and signal-to-noise ratio (SNR) analysis model. In addition, we use Cygnus and crossbar optical routers for numerical simulations to verify the feasibility of the proposed analytical model. In order to improve the availability of Gaussian networks, we propose an optimization method to improve network performance that can effectively avoid the worst case.

A significant trouble in high power microwave (HPM) systems is multipactor discharge – an avalanche of electrons resulting from the secondary electron emission (SEE). It would cause serious problems and limits the attainable power. Nano fabrication techniques, such as sputtering, photolithography, etching and Graphene, are adopted to reduce the secondary electron yield (SEY) of a material to improve multipactor discharge threshold. It is clearly demonstrated that these fabrications can suppress the SEY efficiently. The influence of surface characteristic on SEY is discussed to find that increase porosity and aspect ratio will reduce SEY. These results provided a criterion to determine nanofabrication techniques for multipactor suppression.
