The effect of interface barrier between TCO and amorphous silicon on the photovoltaic characteristics of TCO/a-Si:H(p+)/a-Si:H(i)/c-Si(n) /a-Si:H(i) /a-Si:H(n+) /TCO heterojunction solar cell was simulated by AMPS-1D software developed by the Pennsylvania State University.The results indicate that with the higher inte…
The corrosion behavior of X80 pipeline steel with strain-based design was studied by the electrochemical measurement,weight loss experiment and copper accelerated acetic acid salt spray test. The result shows that in the electrochemical experiment,the X80 pipeline steel with strain-based design has a better corrosion…
The purpose of this article is how to eliminate slab cambering at a slab sizing press in the hot rolling steel production line in some Chinese steel plants. A finite element model of slab sizing pressing was established with the finite element software LS-DYNA. Slab cambering was analyzed at different slab center-line…
The production of piggery biogas slurry was huge in China,and the concentrations of nitrogen,phosphorus and organic pollutants were difficult to meet the discharge standard,and so advanced treatment was necessary. This paper introduced the quality characteristics of biogas slurry. Different treatment methods were comp…
We employed meberane dialysis to prepare curcumin-loaded micelles and addressed the impacts of drug dosage,dialysis time and solvent on drug-loading,encapsulating efficiency and particle parameter to investigate physical and chemical properties and preparation of curcumin-loaded micelles. We also examined their physic…
KIND code is an essential part of the COSINE code package and it is developed for transient calculation and safety analysis of PWR.It is built on the solid foundation of the core simulator CORE code.KIND is designed to be capable of analyzing a variety of PWR core transients from zero to three dimensions.Reactor point…
Comparison study of SOM(solid oxygen-ion membrane) and FFC processes for preparation of titanium directly from TiO2 was proposed.Analysis result of SEM and EDX showed that the oxygen content of production decreased and grain size increased through prolonging electrolysis time,and the metal Ti presented sponge morpholo…
SiB 6-B4C ceramic composites were fabricated by hot-pressed sintering technology using Si as sintering aids.The sintering process and mechanism of Si-B4C ceramics were studied by theoretical calculation,XRD and SEM.The results indicate that Si performances a significant effect on B4C ceramics density sintering and the…
Collecting body measurements correctly in motion state and understanding its changes are very important to apparel ease design.Conventional manual methods with tape and 3-D body scanning are developed based on human body in static state,so they are not suitable for the body anthropometry in motion state.In order to de…
Liquid ternary Fe62.5Cu27.5Sn10 alloy was rapidly solidified under free fall condition.The results show that the liquid phase separation leads to the formation of two-or three-layer core-shell structures and uniformly dispersed structures.These two types of microstructures are both composed of α-Fe and Cu3Sn phases.Ac…
The approximate composition of brittle star Ophiopholis mirabilis was analyzed and the extraction technology of pepsin-soluble collagen( PSC) was optimized from the brittle star powder decalcified by HCL in an orthogonal experiment.The results showed that the brittle star powder contained moisture of 51.80%,ash of 42.…
The response surface method was used to optimize the process of sol-gel enhanced plant fiber-based foaming composite,meanwhile,the influence of the three factors such as pH value,silicon dioxide concentration and addition of sodium silicate on compressive strength was discussed.The results suggested as follows:(1) The…
The research on borate luminescent materials is very active.Because the structure of borate matrix is diversity and the B-O coordination is different,the rare earth borates thought to be a very useful luminescent material in lighting,communications,display,etc.And a lot of research works have been done in this field.T…
The mixture of hydrogen peroxide and vanadium pentaoxide powder was used as a precursor to prepare V2O5 sol on the muscovite substrate.Then the V2O5 film is annealed to fabricate the VO2 film.SEM,XRD were employed to analyze the morphology and microstructure of the film.FT-IR and UV-Vis spectrophotometer were used to…
Effect of three kinds of humectant,hyaluronic acid,glycerin and pro-vitamin B5 on skin performance including skin hydration,transepidermal water loss(TEWL),skin elasticity and skin fine lines were examined.Results showed that glycerin significantly increases skin hydration within 6 h after smearing,while hyaluronic ac…
Nano-crystalline cellulose(NCC) was prepared by sulfuric acid hydrolysis from Pennisetum sinese.The effect of the sulfuric acid concentration,reaction temperature and reaction time on the separation process and the yield of cellulose were analysed.The optimized parameters were achieved by process optimization experime…
In this paper,the typical defects that were found in testing of operating gas insulated switch)GIS) using X-ray real-time direct radiography(DR) were introduced.The bus line of 110 kV GIS,equipped in certain transformer substation of Yunnan,was found unusual sound while operating.Via DR testing,we found the broken ins…
The genetic relationship between 23 color cocoon silkworm varieties cultivated by Ankang University was analyzed by SSR markers.The results showed that 576 bands were amplified by 22 pairs of SSR primers,and the polymorphism rate was 36.44%;the primer with which the largest number of amplified bands was obtained was S…
Objective To investigate the MRI and clinical features of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Methods A retrospective study about 11 inpatients suffered CADASIL was carried out in Beijing Tiantan Hospital from August 2010 to November2012, which included…
The CO2 corrosion kinetics of N80 steel was researched by using high temperature and high pressure corrosion test,corrosion product film analysis and electrochemical measurement technology.The results show that,as time went on,corrosion rate showed exponential decline law.The two stages for the formation of corrosion…
