Present a new intercalated zirconium phosphate composite gel electrolyte for dye-sensitized solar cells(DSSC).The spacing of zirconium phosphate reached to 2.04 nm with intercalated reaction,and the composite gel electrolyte was obtained by adding the Zirconium phosphate into polyethlene oxide(PEO) polymer.The ionic e…
With the help of the elastic wave theory,in the perturbed approximation the density of states for vibrational modes were studied for different hollow Si nanosphere,coupled with a semi-infinite substrate.It was found that the modes of such coupled hollow nanosphere were significantly broadened and shifted toward low fr…
The purpose of this study is to optimize the improvement of foaming properties of albumen protein by papain hydrolysis.Foaming capacity and foam stability were investigated with respect to 4 variables including hydrolysis time,papain dosage,temperature and pH.Two quadratic polynomial regression models describing foami…
Objective: To prepare Zinc(Ⅱ)-carboxymethyl Chitosan complex and study its effect on serum SOD in high fat/high sucrose-fed Wistar rats..Methods: The coordination compounds of carboxymethyl Chitosan with Zinc(Ⅱ) were synthesized and studied by TJ-IR and UV-V.Its effects on serum SOD in the diabetic rats were investiga…
With the rapid development of the electronic industry,electromagnetic interference and electromagnetic radiation are becoming increasing problem that affects people's health,the production security and information security.So the electromagnetic interference shielding is increasingly required.Waterborne conductive coa…
Alginic acid is a natural polymer extracted from brown seaweeds and is a non-toxic,non-hazardous and biodegradable green material.Fibers made from wet spinning of alginic raw materials can be used in textiles,garments and medical fields,serving as a high valued fibrous material.The production process for alginate fibe…
In this report, SiO2 sol gel prepared with the cheap water glass was mixed and coagulated with nature rubber latex to prepare the SiO2/NR composite. The properties of composites were investigated by TG and DMA. The results showed that dispersion of SiO2 solgel particles in NR matrix increased and interface compatabili…
Aimed at intrinsic personality of radioactivity liquid wastewater,several tranditional techniques and new techniques on disposing radioactivity liquid wastewater were discussed.Several suggestions were proposed on prospect of disposing radioactivity liquid wastewater.
This study is to prepare lactosylated chitosan-based nanoparticles used as the carrier for the anticancer drug:methotrexate(MTX) and to provide the reference data for the study of liver-targeting drug carrier systems.Firstly,N-lactosyl-chitosan conjugate(CLCS) was synthesized and characterized by FT-IR and 1H NMR.Seco…
Through the practice of cellulase treatment technology,the main elements influencing the effect of cellulase treatment on cotton knitted fabric were discussed.Research on influencing the effect of cellulase degrading cellulose was made through some specific elements such as temperature,PH value,enzyme processing time,…
The catalytic activity of silica-alumina catalyst heavily depends on its acidic properties in a certain extent.L acid center has the unoccupied orbital which can attract lone pair electron.The unoccupied orbital is the active center of L acid center.B acid center can provide H+,which is the active center of B acid cen…
The corrosion resistance of NMZ1 wear-resistant cast steel was compared with that of the mooring chain steel(22MnCrNiMo) by observing the corrosion morphology and measuring the Tafel linear sweep and electrochemical impedance spectroscopy(EIS) in 3.5%NaCl solution to reveal the electrochemical corrosion mechanism.The…
Oxide dispersion strengthening(ODS) nickel-based superalloys with different contents of nano Y_2O_3(0-8wt%) were prepared by supersolidus liquid phase sintering method.The effects of sintering temperature and Y_2O_3 content on the microstrueture and mechanical properties of the alloy were studied.The results show that…
Effects of input power and frequency on flow field in vacuum induction melting TiAl-based alloy have been investigated by simulation using finite element simulation software-ANSYS.It was found that the distribution of flow velocity was insensitive to increasing input power and frequency which only altered the values o…
We present a systematic study using density functional theory(DFT) with the generalized gradient approximation(GGA) method to understand the adsorption and migration of Pt atoms on the γ-Al2O3(001) surface.Energetically the most favorable adsorption sites were identified and all these adsorption configurations were fo…
The high manganese steel casting and 20 MnCrNi2MoA cast steel with different content of rare earth ferrosilicon were studied by using QUANTA-400 environmental scanning electron microscope(SEM) equipped with EDS for the observation of the inclusion's morphology,size and distribution.The effects of rare earth on the inc…
Effect of aging treatment on microhardness,tensile strength and electric conductivity of Cu-0.15Ag-0.1Fe alloy was studied.The results show that the microhardness and the tensile strength of Cu-0.15Ag-0.1Fe alloy increased rapidly with increasing the aging time and temperature and then decreased slowly.Higher microhar…
Fourier transform infrared spectroscopy can achieve fast identification of phthalate plasticizers in plastics.Using zinc selenide(ZnSe) as the crystal material,adopting ATR technique to do qualitative analysis of the plasticizer was presented.With the dissolution-precipitation method,samples were isolated and purified…
Tungsten doped In2O3(In2O3:W,IWO) film is a new kind of transparent conductive oxide(TCO) film in which W is doped with high valence.Compared with other TCO films,the low carrier concentration,high carrier mobility and the transmittance in the near-infrared band of IWO films are achieved under the condition of the sam…
In order to predict the compatibility of TPI/NR/LDPE blends,solubility parameters of TPI,NR and LDPE were calculated by MD simulations under the COMPASS force field.It was possible to predict that blends compatibility of TPI/NR/LDPE was a miscible system by comparing the solubility parameter value(Δδ) and pair correla…
