Weight-loss measurement, potentiodynamic polarization curve measurement, electrochemical impedance spectroscopic (EIS) measurement, and scanning electron microscopic (SEM) analysis were conducted to investigate the effect of a newly devel-oped triazole compound, 1 -(4-fluoro-phenyl) -3-j4-( [1,2,4] triazol-1 -ylmethox…
Collagen,as natural animal bioresources,is fascinating both in academic research and important applications in biomaterials.The excellent antigenicity biocompatibility degradability and hemostasia ability are the advantages of collagen as biomaterials due to its special biological structure.It is easily absorbable,non…
RE nanophase composite material between the grain size 30nm and 100nm was prepared by the method of mechano-chemistry,in which the material's adsorptive capacity to metal base was checked,and the nature of anti-friction as well as self-repairing effectiveness to the surface of abrasion were tested by four-ball frictio…
Objective:To prepare doxorubicin-tetrandrine complex liposomes for technology study and quality control.In order to provide a new idea to reverse the tumor multidrug resistance in clinic.Methods:The formulations of doxorubicin-tetrandrine complex liposomes were optimized by three different kinds of methods.And the opt…
The compressive strength and flexural strength of magnesium phosphate-based cement doped with fly ash were tested.At the same time the abrasive resistance and expansion rate of MPC-based cement were also investigated.The test results indicate that the compressive strength of MPC-based cement containing 10wt% fly ash c…
The high temperature resistant adhesive was prepared based on liquid polybutadiene epoxy resin(ELPB) cured by pyromellitic dianhydride(PMDA) and benzoyl peroxide(BPO). The research results showed that the influence of BPO on curing reaction of epoxy group in ELPB cured by PMDA was nonexistent,but the influence of BPO…
By using a dynamic test system based on four-point probe method for measuring resistance in order to study the hysteresis of melt structure variation of liquid gallium,the resistivities of liquid gallium superheated and undercooled during heating process,cooling process and holding process have been measured.It is fou…
The ageing treatment of SiCp/AZ61 magnesium matrix composite fabricated by ultrasonic stirring was studied.The results show that the secondary precipitation phase during ageing is Mg17Al12,and the secondary phase is precipitated in continuous and discontinious precipitation ways.Compared with AZ61 magnesium alloy,the…
In order to investigate the capabilities of zircon as waste forms for immobilizing simulated trivalent actinides,trivalent europium(Eu3+) was used as the simulacrum for trivalent actinides,the waste forms containing 20%(in mole) Eu3+ were successfully synthesized by high temperature solid reaction and using ZrO2,SiO2…
A series of novel polymer/salt complexes,based on the blends of waterborne polyurethane(WPU) and polysiloxane(PDMS) as polymer matrix and lithium pechlorate(LiClO4) as doped salt,were prepared successfully.The ac impedance results show the sample with LiClO4 15% possesses the highest ionic conductivity and the relatio…
The data distribution character of jute/kenaf bundle fibers breaking strength was analyzed, using the SPSS13.0 statistical analysis software and Shapiro- Wilk. The results showed that the breaking strength of jute and kenaf fibers approximated to normal distribution. The decision to accept or reject the test data coul…
Based on the process design conditions of NH3 selective reduction unit in Liuzhou Chemical Industry Co.,LTD,this paper explores its process optimation from the following aspects: optimistic control of the O2 content in tail gas, NH3/NOX and NH3 flowrate.These methods are successfully used in treating NOX of nitric aci…
In order to provide the basic parameters for quenching simulation of the crankshaft made of 42CrMo4 steel,its TTT diagrams at austenitizing temperatures of 830 ℃and 850 ℃ were measured by thermal-simulation testing machine.The separation of upper and lower bainites in the bainite C curve was found in the TTT diagrams…
(Mo1-x,Wx)Si2 composites were prepared by the thermal explosion mode of SHS followed by hot pressing using Mo,W and Si powders as raw materials.The effect of W content on the mechanical properties and high temperature oxidation behavior of(Mo1-x,Wx)Si2 composites were studied.The results show that with increasing W co…
Super-high speed polishing of diamond films is a new polishing method,the temperature filed of polishing region affects the polishing quality of diamond films directly.A three-dimensional thermo-mechanical coupled finite element(FE) analysis was employed to analyze the temperature field due to the friction between the…
