The study was conducted with the view of improving the lustiness of the PVC air soles. The formula containing the ingredients; PVC resin, DOP, DBP, R9, Ivamol, MBR did not impart the lustiness on the soles. Hence invention was carried out employing the Methocell F50 and Methocell K100. Interestingly the use of Methoce…
Serious abrasion occurs in power transmission lines in gale, more wind area, mountain micro- terrain meteorological zone in Xinjiang and coastal monsoon zone in our country in recent year. Carry out analysis on reasons of serious abrasion of the fittings under action of gale. Develop research on improvement of abrasio…
In this work we describe the design and construction of a Mossbauer spectrometer based in the use of a Channel Electron Multiplier to detect the electrons emitted as a consequence of the resonant nuclear absorption of γ-Rays by 57 Fe containing samples. The main resonant signals being detected are the Fe(K), Fe(L) and…
In this paper, the initial residual stress field for titanium alloy monolithic component blank is simulated and analyzed by applying a sequentially coupled thermal and mechanical procedure based on finite element method. The control equation of heat conduction of annealing process is studied, and the boundary conditio…
The microstructure evolution characteristics and those effects on microhardness of HSLA (high strength low alloy) 100 steel secondary quenched in the two-phase region were investigated. The results show that the mixed microstructure of ferrite and the M-A（mastenite-austenite）islands can be obtained in the intercritica…
Abstract The paper presents results of examination of material parameters of cast iron with structure obtained under rapid resolidification conditions carried out by means of the nanoindentation method.
Abstract Zur Beschichtung von Magnesiumwerkstoffen werden gerade in der Medizintechnik in erster Linie Fluoridbeschichtungen erprobt, die ein vorhersagbares Degradationsverhalten zukünftiger Implantatmaterialien im menschlichen Organismus ermöglichen sollen. Die Fertigungsschritte einer solchen Beschichtung variieren…
A theoretical study of the ion and interactions within a dimer of ions was performed using various levels of theory and basis sets.Optimisations in the gas phase and in an implicit polarisable continuum solvent model with a variety of solvents showed that there is a significant dependence of the interaction en…
Biodegradability was adopted to evaluate the environment impact of PCDL type of aliphatic hyperbranched polyurethane which was used as the substrate of microorganism. The main results obtained by the method of respiratory curves were as follows. When the concentration of substrate was 0~500mg/L, the respiratory curves…
This study investigated the effect of bone marrow derived mesenchymal stem cells (MSCs) in a PEGylated fibrin gel (PEG) seeded into a decellularized extracellular matrix (ECM) on recovery of skeletal muscle following a volumetric muscle loss (VML) injury.Six to nine month old male Sprague-Dawley rats were used in this…
This paper briefly reviews the nature and application of carbon nanotubes, and the properties of carbon nanotube transport. Pure carbon nanotubes and doped carbon nanotubes at different temperatures are prepared for measuring temperature chemical vapor deposition (CVD). The transport properties are measured and the re…
The slime mould Physarum polycephalum is a suitable candidate organism for soft-matter robotics because it exhibits controllable transport, movement and guidance behaviour. Physarum may be considered as a smart computing and actuating material since both its motor and control systems are distributed within its undiffe…
Self-assembled polymer nanocomposites are a promising class of advanced materials with unique structures and tunable properties. Control over the spatial arrangement and ordering of the constituent material is essential to developing composites with defined morphologies and properties. Here I report the synthesis of p…
Ab initio restricted Hartree-Fock method within the framework of large unit cell formalism is used to investigate the electronic structure of the core and oxidized surface of AlAs nanocrystals. Large unit cells of 8, 16, 54, 64 and 128 atoms are used in the present analysis. Calculations are performed utilizing the Ga…
The experimental observation of the quantum Hall effect in a two-dimensional electron gas posed an intriguing question to theorists: Why is the quantization of conductance so precise, given the imperfections of the measured samples?The question was answered a few years later, when a connection was uncovered between th…
본 연구에서는 보다 효율적인 광 전기화학적 수소제조를 위하여 광촉매로써 산화텅스텐에 티타늄을 함침하여 Ti/WO 3 나노입자를 제조하였다. 제조한 Ti/WO 3 의 물리적 특성은 X-선 회절분석법(XRD), 주사전자현미경(SEM), 발광분광계(PL), 원자간력 현미경(AFM), 정전기 현미경(EFM)을 통해 확인하였다. 메탄올/물 (1/1) 광분해 수소제조 실험 결과, 순수 아나타제 티타니아나 산화텅스텐 광촉매보다 Ti/WO3 광촉매에서 촉매활성이 향상되었으며, 0.5 g의 0.10 mol % Ti/WO 3 촉매를 사용한 경우 8시간 반응 시 3.02 mL의 수소가…
최근 저가의 풍부한 재생 가능 천연자원인 식물성 오일에 대한 관심이 증가되고 있다. 식물성 오일은 친환경적인 생분해성 고분자 물질들의 원료로서 사용될 수 있다. 본 연구에서는 acrylated epoxidized soybean oil (AESO)과 2-aminoethanol의 중합 반응에 의해 poly( ${\beta}$ -amino ester)를 합성하였다. AESO와 2-aminoethanol의 몰비를 변화시켜 다양한 비율의 고분자 필름을 제조하였다. FT-IR을 이용하여 poly( ${\beta}$ -amino ester) 내의 C-N 결합의 생성을 확인하였으…

Growth of nickel tip carbon nanorod by means of pulsed plasma chemical vapor deposition (PPCVD) was carried out at different deposition time. Effects of deposition time under the methane plasma on the growth of carbon nanorod were investigated. The nucleation and growth mechanism of nickel tip carbon nanorod were also…
A novel low-cost shunt hybrid active power filter for power quality in high voltage system is proposed in the paper. The active power filter is based on three-phase four-switch structure. An inductor is parallel in the second-side of the transform, instead of connected in the first-side of transform. An improved SVPWM…
