Phenolic resin based Activated Carbon Cloths(ACCs) were prepared by carbon dioxide activation treatment,and were used as electrodes of supercapacitors.The pore structure and the electrochemical properties of the resultant ACCs were investigated by means of nitrogen adsorption,AC impedance and constant current discharg…
To reduce electromagnetic vibrations and noise in asynchronous motors in the design stage,the harmonic air gap flux density is analyzed.This paper presents an analytical method to calculate the harmonic current and harmonic air gap flux density in squirrel-cage asynchronous motors with consideration of the slotting an…
Nano-TiO2 coated paper of different TiO2 concentration was prepared and used together with preservative film for fresh-keeping of mini cucumber.The sensory quality of mini cucumber was evaluated during storage process.The weight loss,hardness,vitamin C contents and chlorophyll content of mini cucumber were determined.…
Hydroxypropyl cellulose(HPC) grafted with poly(butyl methacrylate)(PBMA) copolymer(HPC-g-PBMA)was synthesized using emulsion copolymerization of the HPC monomer and butyl methacrylate(BMA).Structure of the grafted copolymer was described with Fourier transform-infrared(FT-IR) spectroscopy,X-ray diffraction(XRD) analys…
The optimum processing conditions were determined by orthogonal design to prepare ultra-high molecular weight polyethylene loaded with sodium alendronate(ALN/UHMWPE).The range analysis and analysis of variance(ANOVA) of tensile strength and broken elongation were carried out by statistiacl package for the social scien…
In this paper,from the starting of the sources and the wastewater quality of tannery wastewater,the traditional treatment technology of tanning wastewater and the new processes of tannery effluent were reviewed;the problems in tannery wastewater treatment were studied,and the effective solutions were suggested.Finally…
The La2O3 and Ce2O3 oxides were doped into the Fe-Ni based alloy powder in order to improve the high-temperature properties of Fe-Ni based coating,and the high-temperature oxidation behavior and high-temperature wear-resistant property of the Fe-Ni based coating were also studied.The results show that the microstructu…
The force balance at the point of motion of a shear-driven droplet on surface is studied experimentally.The experiment is carried out in a wind tunnel.A series of liquids and solid surfaces are used to obtain various contact angles of droplet.The velocity required to initiate droplet motion is measured and analyzed,an…
A series of Cu2+-substituted composite metal oxides LaMnO3 were prepared by the improved amorphous citric precursor method(IACP),characterized by XRD,IR,BET and SEM,and tested the performance of ethanol to n-butanol and n-butanal without oxygen.The results showed that the Cu2+-substituted products could reserve the pe…
This article uses bending method to measure the Young’s modulus of brass and cost iron. The key of this method is to obtain the minute displacement of the material under stress. When the Young’s modulus of brass is measured, reading microscope is used to get the minute displacement, with Origin software used to analyz…
Mussels Mytilus coruscus can adhere to various solid surfaces in the presence of moisture.Mussel foot protein-3(mfp-3) has been suggested as the main adhesive protein in the plaques closest to the adhesion interface and also has been suggested as potential environmentally friendly adhesives for use in aqueous conditio…
The model of static recrystallization of low carbon steel was established by cellular automaton method on the basis of subgrain abnormal growing mechanism under the non-uniform storage energy field conditions,and the recrystallization processes at different deformation conditions were simulated.The results show that t…
The precipitates and hydrogen permeation behavior were studied in the low carbon steel for enameling.During the preparation of samples,Ti containing and Ti free in vanadium-bearing microalloyed low carbon steel heating at 750℃ for 3 h,were adopted after cold-rolling.It was found that the a large number of fine VC,TiC,…
As a basic material for the electronic industry,ferrite material has its unique electromagnetic properties and can be used in different fields.This paper will introduce the characteristics of the ferrite material and its applications in and mechanism of anti-EMI and stealth(wave absorption) material.
The Cu-doped ZnO(ZnO∶Cu) films with various oxygen partial pressures are deposited on glass substrates using the radio frequency reactive magnetron sputtering technique.The effect of oxygen partial pressure on the micro-structural and optical properties of ZnO∶Cu thin films are investigated by the X-ray diffraction(XR…
The occurrence status and effect of rare-earth Ce addition on properties of Mo alloy wires have been investigated during the preparation of Mo wires.The results show that in Mo-Ce alloy powders which were prepared by the solid-liquid doping method and reducing processing in the present of H2 as reducing agent,Ce exsis…
