The original foundry technique of the belt pulley was designed by conventional design method in the paper.The Process of solidification of original foundry technique of the belt pulley was simulated by the Z-Cast software.The location and the cause of the shrinkage defects of original technology were forecasted and an…
Triangle silver nanoparticles with unique optical and chemical properties have wide applications in optics,electronics,catalysis and biosensors.Herein,a simple method was used to fabricate triangle silver nanoparticles.Additionally,the studies of thermal stability of nanoparticles were also given in detail.
In current network-on-chip (NOC) studies and in practical applications, the mesh structure is the most widely used and deeply researched structure. However, the hypercube structure is more symmetrical and regular than the mesh or torus structures. This paper compares the network characteristics of these three direct t…
Four new m-chlorophenylporphyrin-5-fluorouracil and its zinc complexes were synthesized and characterized by means of UV-vis,IR,1H NMR and MALDI-TOF-MS.The Infrared and UV-visible spectroscopy characteristics of m-chlorophenylporphyrin-5-fluorouracil and its zinc complexes were discussed in detail.
The intermediate-temperature solid electrolyte with perovskite-type La_(0.9)Sr_(0.1)Ga_(0.8) Mg_(0.2) O_(3-(?))(LSGM) is synthesized using coprecipitation.The forming process of the perovskite phase in LSGM material is analyzed by means of DTA-TGA and X-ray diffractometer,the microstructure and features are tested by…
The isothermal crystallization kinetics and morphology for the binary blends consisting of an isotactic polypropylene (iPP) and a metallocene-prepared linear low-density polyethylene (m-LLDPE,containing 24% hexene comonomer) with three different weight ratios of 70/30,50/50 and 30/70 were examined by using a different…
This paper studies the vehicle after methanol gasoline additive treatment on their performance.According to GB 17930-1999 vehicles using unleaded petrol, the national standard,the modulation of different proportions of methanol fuel,and its before and after adding different additives.The main use of performance indica…
Through analysis of the extracting test results of SMA modified asphalt mixture,it is discovered that the wooden fiber after the extraction selected out by manual work enwraps some fine aggregate,which leads to the quality deviation of asphalt-aggregate ratio and wooden fiber.Aiming at this deviation,the test is carri…
Through carries on the analysis of online wear condition to the numerically-controlled machine tool cutting tool,constructed one kind of online monitor tool wear model,the article elaborated this model's online monitor principle,and has carried on the research analysis to its essential technology.
In the face of the new opportunities and challenges,in the new century to produced a clean fuel,various technologies are in a race to develop,especially in the production of low sulfur,ultra-low sulfur gasoline and diesel technology.In this paper,we carried out an desulfurization experiment with homemade ionic liquid…
The highly pure and ultra-fine (Ba, Sr)TiO3 powder was prepared with sol-gel method, and its average size was about 50 nm. Using such powder with addition of the dopants MgO、ZnO、Bi2O3 and Y2O3, ultra-fine grain BST capacitor ceramics were prepared, and the effect of doping Y2O3 on dielectric properties and microstruct…
After the Mo+C ion implantating,the nano fiber structures were formed in the surface of TiN film.The fiber had a diameter of 2~10 nm,and dispersed uniformly in the TiN film surface.With the help of energy transfer to the deeper zone of the TiN film,nano fiber structures were observed in the fields beneath the surface…
Density functional theory was used to determine the geometric structure and adsorption properties of Pt/ Cu(001)-p(2×2)-O surface using ultra-soft pseudo-potential(USPP) methods.The calculation results indicated the Pt/ Cu(001)-p(2×2)-O surface in favor of no reconstruction adsorbent model with oxygen atoms adsorbed o…
Based on SMP criterion,a new strength criterion is proposed for anisotropic geomaterials.Through the transformation between the principal stress space and the physical space,a normal vector of the SMP is transformed to the physical space.Assuming that the friction angle is changed with the angle between deposition and…
SiO2 glass ceramic was brazed to Ti-6Al-4V(TC4)alloy with commercially available AgCuTi and TiZrNiCu filler foil as braze alloy.SEM and XRD were carried out to study the joint interface and mechanical properties.The experimental result shows that both filler alloy could join SiO2 glass ceramic to TC4 alloy successfull…
Objective To compare the anti-tumor efficacy between liposomal doxorubicin hydrochloride and CAELYX injection.Methods The antineoplastic effects of liposomal doxorubicin hydrochloride and CAELYX injection were evaluated by using mice's transplabted solid tumor S180,S180 ascitic,L1210 ascitic and liver metastasis tumor…
Surface modification of porous polytetrafluoroethylene(PTFE) membrane was performed by chemical method.The morphological and microstructure changes of the membrane surface were confirmed by Fourier transform infrared spectroscopy and scanning electron microscopy.The polar groups were identified by FTIR spectra and SEM…
Four 3,5-disubstituted isoxazoline derivatives(4a~4d)in good yields(84%~95%)were synthesized by 1,3-dipolar cycloaddition of soluble poly(ethylene glycol)(PEG)-supported acrylate with nitrile oxides generated in situ from aldoximes,and then releasing from the PEG using NaOCH3-CH3OH.The structures were characterized by…
Resent Progresses of fluorine containing surfactant were reviewed.Applications of fluorine containing surfactant in paper making,petroleum industry,coating and fire-fighting were introduced in this paper.
β-MnO2 nanorods were successfully prepared by hydrothermal synthesis, using (NH4)2S2O8 as the oxidizing agent and the Mn element came from MnSO4·H2O. The components, crystal structure, morphology, magnetic characteristic and thermal stability of the products were characterized by powder X-ray diffraction, transmission…
