In this study,equilibrium swelling method was employed to determine the crosslink density of natural rubber/reclaimed rubber(NR/RR) blends vulcanizates with different NR/RR ratios,different sulfur contents and different light calcium carbonate contents.Mechanical properties of these vulcanizates were also tested.Therm…
Three kinds of bulk heterojunction organic solar cells were fabricated with different cathode materials including Al,LiF/Al and Ca/Al,respectively.The photoelectric characteristics of cells were characterized,and effect mechanisms of different cathode materials on the cells were analyzed.The results show that when thr…
A new diblock copolymer P1-b-P2 containing substituted triphenylamine as hole transport moieties and substituted 9,10-anthraquinone as electron transport moieties has been synthesized by atom transfer radical polymerization(ATRP).The structures of the monomers and the polymer were characterized by nuclear magnetic res…
The bird impact test for full-size rotor is difficult because of working characteristics of the helicopter rotor.However,in the design process of crashworthy aircraft structure,bird impact test is the ultimate and the most effective verification method.Therefore it is quite necessary to study the test method for bird…
Removing solvent from macro pore resin was studied by using supercritical CO2.The influencing factors such as temperature,pressure,water mass fraction,removing time on the removing rate of residual solvent were inspected with single factor method,and the process was simulated.The study also includes the influence of r…
Combined with the traditional elastic-plastic constitutive theory and the damage evolution methods,according to the irreversible thermodynamic,the inelastic multiplier is introduced,and the damage equation,the flow equation and the evolution equation are derived from a non-associated flow potential function including…
The aconitic acid-acrylic acid copolymer was synthesized by using citric acid as the main material,and that was compounded with polyaspartic acid and zinc salt to get a new kind of high-efficient corrosion inhibitor terpolymer,which performances of corrosion inhibition,scale inhibition and biodegradability were evalua…
The progress of synthesis techniques and applications of the furan resins were summarized and reviewed.The furan resin corrosion-resistant mortars,furan resin based glass fiber binding compositions and concrete were introduced.The development trends and application perspectives for furan resins in the future were fore…
The principle of supercritical fluid deposition(SCFD) and the factors which influence the deposition process are introduced,research progress on preparation of metal,alloy and oxide films by SCFD technique is reviewed.And possible research directions in the future are also suggested.
Ceramic/aluminizing composite coatings on industrial pure copper were prepared by thermo-chemical reaction method and chemical heat treatment.By comparing with thermo-chemical reaction method,the bonding strength and density were improved,its abrasive resistance after sealing is increased to 4.05 times compared with t…
For the harsh ozone-resisting requirement of the ultrafiltration membranes applied on ozone,activated carbon adsorption and ultrafiltration(O3-BAC-UF) integrated water treatment technology,a destructive test on five typical membranes(Polyvinylidene Fluoride,Polyethersulfone,Polyacrylonitrile,Polypropylene,Polyethylene…
A series of chiral anatase(101) nanotubes(NT),which we refer to as(n,0),(0,m),and(n,m),can be formed by rolling up two-dimensional periodic anatase TiO2(101) single layer sheets.Optimized parameters of the atomic and electronic structures of these nanotubes have been calculated using a tight-binding density functional…
The dynamical rheological behaviors of PET/PPBBA flame-retardant composite was studied by using rotational rheometer.The analysis results of the rotational rheological curves showed that PET/PPBBA composite was pseudo plastic fluid,and all specimens exhibited shear thinning behavior.The storage modulus and loss modulu…
The effect of different carbon anode materials with the same projected area on the performance of benthonic microbial fuel cells(BMFCs) is studied,taking max power,anode potential and internal resistance as evaluation indices.The electrochemical activity of different materials is investigated using Tafel plot.The resu…
This paper investigates the field imaging of typical electrostatic problems.For 2D situations,the complex potential function is applied.The contour lines of the real part and imaginary part represent the equipotential lines and field lines,respectively.For the electric field resulted from collinear point charges,the i…
Objective:To establish an HPLC method for determination of ceramide in biological samples.Methods:Ceramide was reacted with preprocessed samples in 1 mol·L-1 KOH ethanol solution to be deacetylated by boiling water bath for 2 h,then reacted with derivatizing reagent o-phthalaldehyde for 60-90 s,with a sample size of 5…
The compatibility of hydrogenated acrylonitrile butadiene rubber (HNBR) and chloroprene rubber (CR) was explored by DSC, DMA and IR. The rubber composites with excellent mechanical properties were produced through adjusting the vulcanization, reinforcing, plastic, and anti-ageing system. The results indicated that HNB…
The T-ZnOw was modified by the chemical deposition method.The modified sample was characterized by XRD,SEM and EDX.The results show that there are cubic system metal iron and hexagonal wurtzite ZnO in the sample.The modified sample really keeps the intact tetrapod structure and its surface is coated fully by spherical…
Objective: To observe the efficacy of uroacitides(CDA-2) in treating anemia patients with low/intermediate-Ⅰ risk myelodysplastic syndrome(MDS).Methods: Twelve patients with low/intermediate-Ⅰ risk MDS received CDA-2 combined with other drugs for 2~4 cycles.The overall response,improvement of anemia and adverse reacti…
In order to resolve the pollution effects of ion barrier Al2O3 film on GaAs photocathode sensitivity of third-generation low-light-level(LLL) tube,we used the quadrupole mass spectrometer to analyze the gas composition released from the ultra-high vacuum chamber,the microchannel plate(MCP) without film and the MCP wit…
