The diblock copolymer chain was flexible in the simulation system. The copolymer chain adsorption on the face center cubic metal crystal surface was researched by MD simulation. The adsorption density has been distinguished by the ratio of A-block beads to B-block beads. The counterions were added to the system which carry the opposite charges to B-block beads. The results show that the strongly binding between B-block and counterions, formed clusters. The copolymer is adsorbed on the bottom surface, which formed a copolymer brush.

In order to reduce the cutting force and improve the surface quality in bone material removal surgery, so as to achieve the purpose of increasing the safety of the operation and beneficial to patients recovery, the vibration-assisted micromilling technology is proposed for the bone material removal process. The influence law of the cutting direction and vibration parameters on the cutting force in the process of vibrationassisted micro-milling of bone material is researched. The experimental results shows that choosing the appropriate machining parameters can reduce the cutting force in vibrationassisted micro-milling of bone materials, which provides guidance for the selection of machining parameters in milling of bone materials.

This study presents the analytical normal and tangential stiffness model of bolted joints considering the coupling effects. Firstly, the stress distribution model within the contact area is proposed with the assistance of finite element analysis (FEA). Then, using the fractal theory and Hertz contact theory, the contact models of single asperity and multi asperities are derived, resulting in the normal and tangential stiffness expression of bolted joints by integrating the contact area. In this model, the largest microcontact area is solved from the contact stress model. Finally, the effects of resultant forces, fractal parameters, material property, and coupling are investigated and analyzed. The proposed model is hugely efficient for predicting the stiffness of fixed joints in machine tools and guiding the optimal functional design under the framework of virtual machine tools.

Micro-deformation is a non-negligible part of the micro-fabrication field, so it is essential to study the structural performances of micro-fabrication equipment. This paper utilizes the finite element method (FEM) to simulate the three working conditions of a horizontal micro-milling machine statically. The optimized structure of the Y-axis has reduced the maximum deformation of the machine tool clamp in the Z- and Y-directions under working condition 1 by 43.7% and 41.6%, respectively.

In this paper, a compact and high resolution in-line digital holographic microscope (DHM) is constructed that consisted of a 532 nm laser, mirrors, microscope objectives $(10times,boldsymbol{text{NA}=0.25}$ and $boldsymbol{40times, text{NA}=0.65}$) and CCD camera. Using the system, a series of holograms were successfully obtained and $mathrm{n}mutext{merically}$ reconstructed to extract the three-dimensional measurements of phase, amplitude and the morphological structure of the tested cells. In this method, the quantitative biological measurements of different types cured cancer cells, involving A549, MCF-7 and SMMC-7721 cells, were all estimated to reveal biological structural information. Moreover, quantitative analysis of SMMC-7721 cell growth changes and drug response were discussed to supply significant information for the treatment of cancer cells.

In order to improve the operational efficiency and quality of underwater robots, this paper proposes a new type of underwater robot, the navigation and crawl underwater unmanned vehicle (NCUUV), and designs a control strategy for it. NCUUV has two motion modes: swimming and crawling, and the motion controller includes the upper controller and the lower CPG network. The CPG network is a star-shaped structure composed of seven Hopf oscillators, which have two configurations: triangular and hexagonal, which control the swimming and crawling of the NCUUV, respectively. The upper controller adjusts the configuration of the CPG according to the movement needs of the NCUUV, thereby completing the free switch between swimming and crawling. The simulation results show that the motion mode switching control mechanism can make the NCUUV realize the motion mode switching stably, and the switching process is stable and reliable.

Chronic kidney disease is a global health problem and wearable artificial kidney is the future trend. The size of wearable artificial kidney depends on the size of dialysis volume. In this paper, based on the current peritoneal anatomy and physiology, we investigated a modeling analysis study of the dialysis equivalent, which was based on the three-pores model describing the transport of substances across the membrane. From the results, it was found that as the volume of dialysate becomes smaller, the maximum volume of dialysate appears earlier. It provides the basis and ideas for the design of the volume size of the wearable artificial kidney.

A flexure-based precision positioning stage driven by voice coil motor (VCM) with integrated active eddy current damper (ECD) is proposed in this paper. This device is constituted of two identical VCMs, one ECD and one compound double parallelogram mechanism (CDPM). The VCM with Halbach permanent magnets (PMs) array is designed to yield a large driving force and low force ripple. The CDPM is selected as the flexure guide with the advantages of deterministic motion and high precision displacement transmission. The double-sided active ECD is proposed to suppress the residual vibration especially in the deceleration or stop motion process. Based on the analytical models and theoretical analyses of the VCM, the ECD and the flexure guide, the relationship between the input driving current and output displacement is obtained. Finite element analysis (FEA) is carried out to verify both the electromagnetic and dynamic performance of the designed stage. The results validate that the proposed stage can achieve a large motion range about $boldsymbol{pm 5text{mm}}$, deliver the force-constant variation less than 2%, and possess a high bandwidth approximately 55Hz.
