Metals and their alloys are an important type of structural and functional material and have been widely used in the aerospace,automobile,shipbuilding and other industries.The macro-properties of metallic alloys actually depend on their microstructures.The evolution of their microstructures generally involves a dynami…
In order to solve the compatibility of PBS/PLA blends,the peroxide compounds-dibenzoyl peroxide(BPO)and dicumyl peroxide(DCP)were reacted.The compatibility and mechanical property were characterized and tested by SEM,PLM,DMA and DSC.The experiment proved that the joining of compounds BPO or DCP made the phase structur…
Magnetic nanoparticles,mainly ferrite(γ-Fe2O3 and Fe3O4) are a kind of new material,which develop very fast in recent years.Because of their non-toxicity,non-harm and biocompatibility,more and more attention has been focused on them.At present,magnetic nanoparticles have attracted a great attention in various fields,s…
The ternary compound ferroelectric thin films,6% Pb(Mn1/3,Nb2/3)O3-94%Pb(Zr0.45,Ti0.55)O3(PMnN-PZT),were deposited on the MgO substrates by the magnetron sputtering method,and the quench method was adopted for the post heat treatment.The out-plane and in-plane X-ray diffractions were used to characterize the crystal s…
The mechanical properties and corrosion fatigue properties of low carbon bainite steel after heat treatment under water and salt water conditions were investigated by scanning electron microscopy(SEM),transmission electron microscope(TEM) and X-ray diffractometer(XRD).The results indicated that,compared with as-rolled…
To evaluate the biologic wear properties of the nitrogen-doped TiO2-xNx films on brackets.To produce the nitrogen-doped TiO2-xNx films on the surfaces of stainless steel metal brackets by the method of radio frequency magnetron sputtering.The microstructure and the biologic wear properties of the nitrogen-doped TiO2-x…
The measurement of fireball of a thermal-baric explosive for three kinds of grooving shell was accomplished by high-speed photogrammetric system,and the batch program of fireball dimension was compiled by VB.The batch program of fireball dimension realizes better disposal to experimental information.The process of fir…
An HPLC method for determination the content of chlorogenic acid in Cynanchum paniculatum(Bge.) Kitag was established,Using 70% methyl alcohol to extract chlorogenic acid from Cynanchum paniculatum(Bge.) Kitag by Soxhlet extraction method.The determination was measured by HPLC with SHIMADZU-C18(250 mm×4.6 mm,5 μm)colu…
Taking 14.7tex 15/20/65 cashmere/black charcoal bamboo/long-staple cotton blended knitting yarn as an example to introduce black charcoal bamboo fiber blended yarn processing flow and the attentions in the spinning process.The first thing is to design a reasonable spinning process route with appropriate process parame…
The isothermal cure kinetics of modified epoxy resin by carboxy-terminated butadiene acrilonitrile copolymer at varying contents,and the effects of liquid contents on cure kinetics of epoxy resin were investigated at three different curing temperatures.The curing process of the modified epoxy resin by a liquid rubber…
In this investigation,we analyse the corrosion behavior of mild steel immersed in two inoculated cultures with different ferrous concentration-0mg/L and 30mg/L.The optical microscope and electrochemical impedance spectroscopy(EIS) were used to obtain the photos and EIS data of mild steel with different immersing time.…
The nanocrystalline ZnO films with highly C-axis orientation and low residual stress of were prepared on ordinary glass substrates with high purity ZnO powder as target.The structure and microstructure of the films before and after annealing were analyzed.The results indicate that except for those sputtered in pure ar…
The study on technology of ethanol dehydration by pervaporation showed that separation factor and permeation flux increased with temperature enhanced;when water content increased,the separation factor declined and permeation flux increased;once flow changed,separation factor and permeation flux increased with flow enh…
Ln3Al5O12(LnAG,Ln=Y,Ce,Yb) lanthanide aluminium garnets nanopowders were prepared by co-precipitation method with Y2O3,Yb2O3,Al(NO3)3·9H2O and Ce(NO3)3·6H2O as raw materials,NH4HCO3 and NH3·H2O as co-precipitator.The precursor and calcined powders were characterized with TG/DTA,XRD,SEM and TEM.The results show that we…
[Objective] The research aimed to study the effects of the soils spiked black carbon on the sorption behavior of norfloxacin.[Method] The black carbon was obtained by rape residue firing in open air.The effect of the black carbon on the sorption of soils to norfloxacin was studied using the batch equilibrium.[Result]…
Expanded graphite,because of its unique structural characteristics,had good absorption,electric conductivity,corrosion resistance and other characteristics,which was wildly used in sewage treatment,air purification,etc.The structural characteristics and properties of expanded graphite were introduced,and its applicati…
The amphoteric hydrophobic association polyacrylamide(HAPAM),AA/AM/HAMC8S/DMDAAC,with hydrophobic carbon chain,sulfonic group and quaternary ammonium group,was synthesized using AA,AM,DMDAAC and HAMC8S as monomers,and the average molecular weight of the polyacrylamide was 5.5×106.The structure was characterized by mea…
Cationic cellulose was synthesized by using bagasse bleached kraft pulp and 3-chloro-2-hydroxy propyl trimethyl ammonium chloride(CHPTMA) as raw material and using microwave heating.The optimal synthesis conditions were determined: quality ratio of etherifying agent and cellulose 0.45,quality ratio of NaOH and etherif…
Three types of polythene anti-corrosion layer(3PE coating,heat shrinkable wraparound sleeve and heat shrink sleeve)were studied by observing the changes of cathodic protection current with different cathode polarization potentials in the cathode stripping process and cathodic disbonding resistance performance in diffe…
