In this paper, we got Ni-MWNTs through pretreatment of MWNTs and electroless plating of nickel, and observed the Ni-MWNTs and MWNTs with TEM and FTIR. In addition, we prepared Ni-MWNTs/EP and MWNTs/EP composites. The volume resistivity、permittivity and permeability of composites were measured. Results showed that the…

Stress and deformation analysis of 950 mill housing was done by means of ANSYS to calculate the maximum stress and deformation. Strength and stiffness of the mill roll were checked to meet requirements. Carries on the modal analysis to the rolling-mill housing, obtains its first 10 steps the natural frequency and the…
Computer aided design of the manufacturing technology for anchors is presented in the paper. Evaluation of applicability of various materials for anchors, as well as analysis of the influence of process parameters on the in use properties of product, were the objectives of the research. In the material part, bainitic…
In recent years ferroelectric polymer-based nonvolatile memory devices have attracted much attention due to their flexibility, transparency and ease of production. However, their electrical stability is seldom studied. In this letter we report the observation of electric fatigue in metal/ferroelectric polymer/SiO2/p-S…
The morphology and roughness of nanostructure of Au film are discussed using an atomic-force microscope (AFM) and a laser Raman spectroscopy. The Au films are deposited on mica and Si substrate by means of a dc plasma sputtering technique, and a self-assembled monolayer (SAM) of benzene-thiol is formed on the Au films…
The 11th Asia–Pacific Conference on Plasma Science and Technology (APCPST-11) was held in Kyoto, Japan on 2–5 October 2012 with the 25th Symposium on Plasma Science for Materials (SPSM-25). SPSM has been held annually since 1988 under the sponsorship of The 153rd Committee on Plasma Materials Science, Japan Society fo…
Roll collar is one of the major consumption of spare parts in steel rolling production,it is excessive alternating thermal stress in the harsh working conditions. It is very important to control their size and variation of temperature. Temperature variation is unable to use experimental methods, but using the numerica…
A novel copolymer based on bromobenzene and 3,4-ethylenedioxythiophene (EDOT) was electrochemically prepared in boron trifluoride diethyl etherate (BFEE) via direct anodic oxidation of the monomer mixtures on indium-tin oxide working electrodes. The corresponding polymer was characterized by cyclic voltammetry and UV-…
In this work, CoS flowerlike microclusters with well-aligned nanoflakes were synthesized using a facile solution-phase biomolecule-assisted approach in the presence of L-cysteine (an ordinary and cheap amino acid), which turned out to serve as both the S source and the directing molecule in the formation of cobalt sul…
We have proposed two novel processes for the formation of fine n/i interface to improve the photovoltaic performance in substrate-type (n-i-p type) hydrogenated microcrystalline-silicon (μc-Si:H) solar cells whose i layer is deposited at high growth rate of > 2.0 nm/sec; (1) gradual monosilane-(SiH 4 )-molecule-introd…
Material behaviour description frequently used in commercial codes may not be adequate to simulate real forming processes. One of the reasons is the fact that they rarely include the modeling of internal damage of material. This is a decisive feature in order to be able to predict defective parts in processes like for…
Titanium alloys, such as Ti-6Al-4V, offer favorable characteristics as significant strength, biocompatibility and metallurgical stability at elevated temperatures. These advantages afford the application of parts out of Ti-6Al-4V in a wide field within aerospace, astronautic and medical technologies. Most applied shap…
In this paper, a non-orthogonal constitutive model [1] is used to investigate the effect of sample misalignment due to ‘tow meander’, across the initial blank sheet on the shear compliance of a woven glass fabric, as measured using the biaxial bias extension test with various transverse loads applied [2]. The same sta…

In order to get ultra-smooth surface without subsurface damage efficiently for fused silica, the atmospheric pressure plasma processing (APPP) is developed. It is based on chemical reaction between active radicals excited by plasma and workpiece surface atoms, so the subsurface damage caused by contact stress can be a…
A comprehensive understanding of the inherent link between in-situ growth kinetics of a polymer spherulite and high-pressure constraints under controlled temperature is concerned. As a matter of fact, while the link with temperature is well illustrated, little comprehensive study has been conducted to quantify the eff…
Numerical modeling of the heat treatment is developed over the past 30 years and connected to the industrial applications. This requires a good insight in the thermal, mechanical and metallurgical behavior of steels and the coupling effects among these physical phenomena. To describe these effects, a suitable material…
