Polarization laser direct-writing system was designed and the recording holographic phase grating on azobenzence polyester film on the system was investigated.The influence of laser intensity and different azobenzence polyester material about surface topology by the movement of molecules(10 nm max.),refractive index(0…
Baby's home textiles market in China is still waiting for development to meet the demand.The design of baby's home textiles should be considered to meet the requirements of comfort,health,environment protection and the well-growth of the children.In this paper are introduced some designing and processing technology in…
The polyurethane elastomers with 0￣60 shore A hardness were synthesized by one step method. The elastomers have a very good resistance to solvents and can be used in printing industry, such as color coating, etc. The influence of isocyanate type, index, polyester structure, curing temperature, etc. on hardness, mechan…
The nanometer-sized ZnO is prepared using three different kind of precipitator,and as-prepared nanosized zinc oxide powder is characterized by X-ray diffraction,scanning electron microscopy,diffuse reflectance ultraviolet-visible spectroscopy and IR spectra.Photocatalytic decolorization of methyl orange wastewater is…
Liquid crystals are being used in high resolution TV, projection systems and optical communication networks. For their applications it is important to know how the liquid crystal's response varies with surface treatment. But if a small pretilt angle at the surface is actually present, an apparent extrapolation length…
Bacterial Cellulose(BC)/Carboxymethyl Cellulose Sodium(CMC)nanocomposite was synthesized through the method of adding CMC to the growth medium of the cellulose-producing bacterium,Acetobacter xylinum.The amount of CMC and growth time on the mechanical and swelling properties of nanocomposite were researched and analyz…
Nonisothermal crystallization and melting behavior of nylon 6(PA6) and nylon 6/ployolefin elastomer(POE)/clay nanocomposite by differential scanning calorimetry (DSC) were mainly investigated.Nonisothermal crystallization curves showed that crystallization exotherms bacame wider and crystallization peak temperatures s…
Adsorption and corrosion inhibition of nitrazine yellow on cold rolled steels in 1.0 mol/L HCl solution was investigated by weight loss method.Results showed that nitrazine yellow acted as a moderate corrosion inhibitor,and the inhibition efficiency was increased with nitrazine yellow concentration,while decreased wit…
HfAlO high-k dielectrics are deposited on Si(100)by atomic layer deposition and the effects of N2 and NH3 post-deposition anneal are investigated.Through the change of ALD process,we can deposit three kinds of HfAlO film with different Al∶Hf atomic ratio.The capacitance-voltage(C-V)characteristics indicate that accumu…
Copper mold casting was employed to fabricate Mg80 Zn16-x Ca4Alx( x =2,4,6) and Mg75Zn17Ca4Al4 high strength as-cast alloys. The microstructure,the fracture surfaces,the phase constituents and the mechanical properties of the alloys were analyzed by using of scanning electron microscopy(SEM) ,X-ray diffraction(XRD) an…
The relative theory of the safety and efficiency as well as experiment are presented for the high-rated current lead design. The experiment results indicate the safety property is associated to current density of the resistive heat exchanger (HEX) and temperature margin of the HTS module. The HEX cooling mass flow rat…
The linear viscoelastic behavior and electrical conductivity of high-density polyethylene (HDPE) filled with stainless steel fibers (SSF) were investigated and compared with those of carbon black (CB) filled HDPE composites system.It is found that CB/HDPE composites show two electrical conductivity percolation values…
Seven texture parameters such as hardness,springiness and gumminess of ark shells were tested by using a texture analyzer.Significance tests and correlations of these parameters were processed by SPSS statistical software.The results showed that there were great differences among various ark shell samples,but we could…
The two degradable poly(silyl ester)s included poly(1,1,5,5-tetramethyl-3,3-diphenyl-trisi1oxyl adipate) and poly(tetramethyldisilyloxyl adipate) were synthesized by a new route via the condensation of di-tert-butyl ester of dicarboxylic acid with dichlorosilane.The chemical structures of the poly(silyl ester)s were c…
In this article,multi-dimensional numerical simulation about velocity field and pressure field of steady flows in the catalytic converters for three different entrance angle of the expansion tube is performed.Simulation results show that the entrance point of the expansion tube has a great impact on the flow of cataly…
ZrO_2 porous ceramics with gradient pore distribution are prepared by centrifugal slip casting method using two kinds of ZrO_2 powders with different particle size.Zeta potentials of ZrO_2 particles at different pH values are measured.The effect of centrifugal acceleration and solid loading of slurries on segregation…
In terms of traditional theory,decorticating extrusion refers to decorticate copper billet by applying plastic shearing deformation theory and adopting dummy block which has smaller O.D than copper billet,therefore,appearance quality of decorticating extrusion process should not effect on the dimension of extrusion tu…
The bit-sharpener is a crucial component in the coal mining machine. It needs high wear resistance and high impact resistance. The cast alloy steel bit-sharpener has been prepared by pouring the chrome abrasion resistance steel and the low-alloy steel with fine impact resistance one-step using cast-in technique. And t…
The kinetics of the hydrolysis of p-nitrophenyl picolinate(PNPP) catalyzed by zinc complex of schiff base macrocyclic polyamine(Zn2+ complex of 1,4,7,10,13,16-hexaazacyclooctadeca-1,3,10,12-tetraene was abbreviated to ZnL2+)were studied at 25℃and pH=7.00.The pseudo-first-order rate constant(kψ)of the catalytic PNPP hy…
To obtain polyclone antibody against Fib-L,rabbit was immunized by multiple-site hypodermic injection with the purified Fib-L proteins.
