Ionic polymer metal composite actuators (IPMCs), a new kind of smart material, have taken much attention as suitable candidates for the next generation actuators, micro-electromechanical systems, medical devices and micro air vehicles. In this paper, a new kind of IPMCs was developed by incorporating sulfonated poly (…
Based on the density functional theory, this paper calculated the geometrical and electronic structural properties of ZnO(11¯20) surfaces and analyzed ZnO(11¯20) surfaces in the structural relaxation, electron density difference, densities of states and the Ti adsorption by using the first-principles and pseudopotenti…
We found that positive-tone photosensitive polyimide (posi-PSPI) shows not to be compatible for electroless Ni/Au plating process which are used for Au micro bumping. In order to meet compatibility for the process, we improved chemical resistance of positive-tone photosensitive polyimide especially for electroless pla…
Carbon nanotubes (CNTs) have been attracting increasing attention for the possibilities of their widespread applications in the field of engineering. On the other hand, the research on the influence of CNTs on human organisms is still scarce. Among the limited studies, some indicate that CNTs have genotoxicity or cyto…
A novel biodegradable and biocompatible composite of Poly (propylene carbonate) (PPC) and graphenes oxide (GO) was prepared by a solution blending method. The chemical structure, thermal properties and microscopic morphologies of the GO/PPC composites were characterized by Fourier transform infrared spectroscopy (FT-I…
Based on taking combustion synthesis in ultrahigh-gravity field to prepare solidified TiC-TiB2 ceramic, laminated composite of TiC-TiB2 to Ti-6Al-4V was successfully obtained by fusion bonding, and within the joint there achieved multi-scale (micron-submicron-micro-nano) and multi-level (TiC1-x-TiB-TiB2 + TiB2-Ti-TiC1…
An equivalent circuit representation of the metamaterials with extended constitutive relationships which are coupling between the electric field and the magnetic field are derived. Those are analogized in coupled transmission lines and reciprocity, passivity, and reactivity are investigated by using this equivalent ci…
This study synthesized silicon emulsions by emulsion polymerization, mainly focused on how influencing factors including catalyst, emulsifier, reaction temperature and synthesis process could affect product conversion rate, appearance and molecular weight. The result showed that the conversion rate of the first 2 hour…
Dinuclear supramolecular complex of praseodymium nitrate with an unsymmetrical tipodal ligand benzyl-N,N-bis[(2′-benzylaminoformyl)phenoxyl)ethyl]-amine (L), have been prepared. The X-ray single-crystal diffraction analysis indicates that this complex was crystallized in the monoclinic system, space group P21/c with p…
Deformation behavior of high Mn TWIP (twinning induced plasticity) steels was observed using neutron diffraction. Two kinds of specimens were prepared; 0 and 2 wt% of Al TWIP steels. The lattice strains and peak widths of hkl grains were measured under tensile loading. The results provide an insight into the influence…
Based on a diesel engine fuelled with BD20 biodiesel, particle number (PN) emission characteristics of the engine equipped with DOC, DOC+DPF and none after-treatment device were investigated respectively by engine bench tests. Results showed that both of DOC and DOC+DPF reduced PN emissions, DOC mainly reduced PN in s…
In the present study, ITO nanocolumn was successfully deposited onto a glass substrate by RF magnetron sputtering. The effect of deposition pressure was investigated. X-ray diffraction analysis indicates that the intensity of the (400) peak orientation is highest at sputtering pressure of 5 mTorr. The results from UV-…
This paper presents analysis of circular microstrip patch antenna placed over a thin grounded pin bed type reactive impedance surface (RIS). Effect of the variation in the height of the pins on the resonant frequency and the radiation properties of antenna have been studied. 3D EM simulation tools based on finite elem…
Possibility of forming titanium nitride by anodic polarization of the surface of titanium in water-containing organic electrolytes in the presence of NH 4 F at potentials of 2–14 V was demonstrated and substantiated. The method of cyclic voltammetry was used to study electrochemical processes in electrolytes based on…

The design and research of weft insertion mechanism of carbon fiber multi-layer loom which has the great significance for the development of modern 3D weaving equipment. According to the special requirements of carbon fiber multi-layer weaving fabric, a multilayer weft insertion system incidental finding device is des…
The problem of selection of the initial approximation for the task of identifying the electrical parameters of direct-gap semiconductors by the method of confluence analysis using the dependence of the intensity of the monochromatic cathodoluminescence caused by the quadratic recombination of minority charge carriers…
n-Type NC-FeSi2/p-type Si heterojunctions were successfully fabricated by PLD, and their forward current-voltage characteristics were analyzed on the basis of thermionic emission theory (TE) in the temperature range from 300 down to 77 K. With a decrease in the temperature, the ideality factor was increased while the…
In this study, we investigated the effect of MgO nanofiller content to the dielectric layer properties of nano-MgO film. Nano-MgO film was successfully deposited with particle size in the range of 42 to 92 nm by simple chemical solution technique. The film produced shows some surface modification as the nanofiller con…
The photocurrent spectra of Si:Er/Si epitaxial diode structures are studied. It is shown that the nature of the sub-band-gap photoresponse is determined by the epitaxial growth temperature of the Si:Er layer and is not related to the composition of erbium emission centers. It is found that the absorption of light with…
