The polyethylene oxide like( PEO-like) film prepared by plasma polymerization has high hydrophilicity and anti-bioadhesion,which can be used to modify the biomaterial surface to improve the inhibition of protein adhesion,platelet adhesion and anti-bacterial adhesion. The PEO-like films on stainless steel( SS) substrat…
Bithiophene bridged bis-terpyridine(BTTPY) was synthesized in a total yield of 13%,via formylation,Krhnke pyridine synthesis and Suzuki coupling with 2,5-dibromothiophene as raw material.UV-Vis and fluorescence spectra of BTTPY exhibit strong red shift in acetic acid and trifluoroacetic due to strong protonation.UV-V…
Based on the excellent electrocatalytic effect of the graphene nanoplatelets modified electrode(GHNP/GCE) toward the electrochemical reaction of ascorbic acid,a new method for electrochemical determination of ascorbic acid was established.Compared with the bare glassy carbon electrode(GCE),the graphene modified electr…
The performance of NO reduction by reburning with calcium acetate(CA),limestone modified by acetic acid(LMAA) and limestone modified by wood vinegar(LMWV) in simulated O2/CO2 coal combustion gas was investigated using a drop tube furnace.The effects of operating parameters on nitric oxide reduction were explored,inclu…
Sr2MgSi2O7 ∶ Eu2+,Dy3+ long afterglow phosphor was prepared by sol-gel-combustion method. The results show that the pH of the solution has a significant impact on the formation of sol. In order to form a stable sol, the pH must be controlled at between 2 and 3.Then it could get better performance of Sr 2MgSi2 O7 ∶ Eu2…
Oxidized starch-aminothiazole Schiff-base(OSAT) was synthesized based on the reaction of aminothiazole(AT) and water soluble oxidized starch with high carbonyl content which was prepared by the oxidation of sodium hypochlorite.The synthesis conditions of OSAT were studied and the optimum conditions were as follows:nit…
A novel method was developed for preparing woody activated carbon of high performance assisted by mechanochemical process(MCP) with phosphoric acid.In the experiments,variables like milling time,activation temperature,impregnation ratio(the ratio of the mass of phosphoric acid to dry chinese fir sawdust),concentration…
Stable poly(alkyltrialkoxysiloxane) aquous emulsions with different polymer contents were prepared by copolymerization of methyl triethoxysiloxane and n-propyl trimethoxysilane.The structure of the copolymer and the morphology of emulsion particle were characterized by Fourier transform infrared spectroscopy(FT-IR),tr…
For ferromagnetic materials(such as low carbon steel,low alloy steel,etc) are liable to defect or fracture in the long-term and thus to cause accidents,the internal structure of the ferromagnetic materials and change tendency are studied in the paper.By the combination of the magnetostrictive effect and Faraday princi…
In order to improve absorption and utilization of solar light,carbon,cobalt co-doped mesoporous nano titania with anatase crystalline structure(C,Co-MTiO2) was prepared using templating method.The catalyst was characterized by techniques like N2 physisorption,X-ray diffraction(XRD),HRTEM,UV-Vis.The characterization re…
An imidazoline quaternary ammonium was synthesized from tung oil,rosin,diethylenetriamine and chloroacetic acid.The corrosion inhibition performance of the product on A3 steel in 15% phosphoric acid solution was investigated by weight-loss method.The anti-corrosion performances of the product and the mixture of the pr…
A supported photocatalyst PW11Fe/D301R was prepared by loading the keggin substituted heteropolyanions PW11O39Fe(Ⅲ)(H2O)4-(PW11Fe) onto the anionic exchange resin D301R through ion exchange,and is used for visible light degradation of organic dye contaminant rhodamine B(RhB) in aqueous solution with examination of the…
Taking ternary eutectic alloy as research object, a multiple and heterogeneous solidification microsegregation model was established using Thermo-Calc coupling algorithm, and the computer simulation program was designed based on the model, Al-10Cu-2.5Mg, Al-4.5Cu-1.0Si and Fe-40V-40Cr alloys were numerically simulated…
