This study is devoted to understanding the thermodynamic basis of the process of synthesis of ZnS, CdS and their solid solutions in aqueous solutions in order to obtain thin films of required composition. The typical interfacial reactions were considered, and the thermodynamic calculations of the possible redox reacti…
We succeeded in determination the biodistribution of several nano-sized particles administered to mice through the tail vein. After administration, these particles were observed in the lung, liver and spleen. The distribution behaviors depend upon not only chemical species but also the particles size. To estimate thei…
The 2Cr13 axle sleeve, used in N52 water pumps, suffered wear after being tested for a relatively short time and fractured when it was beat under the dynamic load. Optical metallographic microscopy, scanning electron microscopy (SEM) and Vickers hardness tester for the fractured 2Cr13 axle sleeve were used to determin…
The aim of this paper is to investigate the microstructural characteristics and creep resistance of Mg-(8-12 Wt. %) Zn-(2-6 Wt. %) Al alloys in order to get a better overall understanding of these series alloys. The results indicate that the alloys studied with the ratio of Zn/Al concentration between 2 and 3 exhibit…
In this paper, the corrosion behaviors of Sm-based bulk metallic glasses (BMGs) were investigated by immersion test. It was found that with Co content increasing the ability of corrosion resistance of the alloy increases for Sm-based bulk metallic glasses. A comparison study was made on the corrosion behaviors between…
From the origin of the copper clad aluminum wire, Discussed copper clad aluminum wire structure, performance, and an overview of the preparation process of the copper clad aluminum wire, Analysis copper clad aluminum wire applications and problem in applications, and finally summed up: As long as we solve good copper…
To solve the problem that is the poor demagnetizing effect and stability issues by the way of demagnetization in the one-dimensional space, a new degaussing method was studied in this paper, based on the analysis of magnetic moment angle distribution during the degaussing deal to iron material. Through the magnetizati…
Glassy samples from the GeSe2-Sb2Te3-CdTe system are synthesized. The thermal characteristics (glass-transition Tg, crystallization Tcr and melting Tm temperatures) are determined using differential thermal analysis. On the base of the values of these temperatures the glass forming ability of the glasses is determined…
Brass and cooper are widely used in heat pump water heater as heat exchanger between refrigerant and water, and the scaling is seriously at 60°C. Study the precipitation characteristics of CaCO3 is the first step to research anti-fouling technology. CaCO3 precipitated on brass and copper coupons from 0.5mmol/l CaCO3 s…
This paper mainly researches the eddy current losses of transformer shielding coil by adopting for analytical method. This method calculates the conductor’s boundary conditions directly by using the analytical solution of the leakage magnetic field, which is generated into the conductor eddy current equation for the a…
±1000kV DC wall bushing under planning is a complex insulation system which bears the effects imposed by different working conditions. The electric field distribution is concentrated at the bushing outlet terminal, which might result in breakdown discharge especially when short-time abrupt conditions such as polarity…
Aimed at relieve the human labor intensity, boost work efficiency and lower production costs, a hydraulic mulberry trimmer is developed, which is introduced in this article. Specifically, the cutting principles and motion parameters are analyzed in the processing of trimming, and then the feasibility of the selective…
Starting with the numerical calculation of the Fourier spectrum of the orthogonal phase-coded beam, a fundamental study on hybrid phase-coding and spatial multiplexing shows that there will be a complex and serious fluctuation in both intensity and phase distribution in the reference beam if a Fourier transform config…
The ground state geometrical of cyclic sulfur molecules S8 has been studied with RHF/6-311G* of ab initio methods. Gibbs free energy of CO, SO2, S8 and CO2 from 300 to 1673K has been calculated using ab initio method. Besides, the reaction free enthalpies were calculated. The results show that resultants of reaction o…
Direct pulp capping involves the application of dental materials to the exposed pulp in an attempt to act as a barrier, protect the dental pulp complex and preserve its vitality. The materials for direct pulp capping should ideally adhere to dental pulp tissue as soft tissue and dentin as hard tissue with tight sealin…
Since the first Korean nuclear power plant (NPP), Kori 1, commenced operation in 1978, a total of 21 NPPs had been put into operation in Korea by the end of 2011. Radiation doses of NPP workers have been periodically evaluated and controlled within the prescribed dose limit. Radiation dose assessment is carried out mo…
The reconstruction and electronic structures of the interfaces between single wall carbon nanotubes and ferromagnetic Co electrodes were studied in the framework of density functional theory. The obtained results revealed that there is a strong interaction between carbon nanotubes and Co electrodes. At the interface r…
This approach combines the gauge field theory of spin-glasses [1, 2, 3, 4] with the critical dynamics methods in order to describe the glass transition. The glass transition is regarded as a phase transition, which is interrupted because of premature critical slowing down, caused by the frustrations. The frustrations…
Plasma nitriding technology was carried out on the surface of bearing steels. The phase composition and microhardness of the nitrided layer were analyzed. Sliding wear characteristics of the nitriding steel were studied on an Optimol SRV IV oscillating friction and wear tester at room temperature. The fretting wear me…
At present, most studies on magnesium alloy sheet forming were carried under hydraulic press. In this paper, differential temperature forming of AZ31B magnesium alloy sheet under the J23-63 mechanical press were carried out. Through an orthogonal test about studying the influence of process parameters on AZ31B magnesi…
