The effects of pullulan and glycerol addition on the tensile properties,optical properties and barrier properties of edible film were studied.The result showed that the addition of pullulan dramatically improved the elongation at break,oxygen barrier,luminousness and tensile strength of edible film;when the amount is…
To improve the BaTiO3particles response to electric field in hydrous elastomers,the composite particles with BaTiO3/gelatin core-shell structure were prepared by microemulsion method.Particles’morphology,structure,composition and surface hydrophile have been characterized by TEM,XRD,FT-IR,TG and optical contact angle…
Graphite intercalation compounds loaded with titanium oxide( TGICs) were prepared by chemical oxidation method. Influence of expansion temperature on expanded volume of expanded graphite loaded with titanium dioxide( TEG) and its decoloration performance for direct deep blue C-3R(DDB) was investigated. Results of ther…
In orde to improve the ability of high temperature anti-oxidation,high-temperature oxidation resistant ceramic coating on Ni-alloy surface was prepared at 1300 ℃,using Cr2O3 and cementing phase as the starting material.The experimental results indicate that the dense enamel coating has an excellent thermal shock resis…
Taking oxidized chitin as the cross-linking agent,the composite gelatin membrane has been prepared by solution cross-linked method.The influence of carbonyl group content of the oxidized chitin on the thermal stability and water absorption behavior of the composite membrane has been researched.The results show that th…
Li-excess Mn-based cathode materials xLi2MnO3·(1-x)LiMO2have a high capacity(200-300mAh/g),which would well satisfy the requirements in small electronic products,hybrid electric vehicles and other areas,and they are considered to be the most potential cathode materials for the next generation power lithium-ion batteri…
According to the conserved sequence of polyhedrin gene in silkworm(Bombyx mori) cytoplasmic polyhedrosis virus(BmCPV),a pair of specific primers were designed to establish a real-time fluorescent quantitative PCR method for detection of BmCPV and were applied in detection and analysis of BmCPV proliferation in silkwor…
A new environmental friendly degreaser was developed by using biodegradable anionic surfactant sodium ligninsulfonate as substitute for sodium dodecylbenzenesulfonate(LAS),and compounded with alkyl glycoside(APGC8-10) as green nonionic surfactant,AEO-9 as a biodegradable component,polyaspartic acid(PASP) and sodium me…
ABEEMσπ method was used to calculate the electronegativity of several neutral dipeptides and tetrapeptides,then the arithmetic mean value,geometric mean value and harmonic mean value of the preceding two items added in the effective electronegativity calculation formula of all sites in molecule were calculated to comp…
Drafting a series of casting process schemes for high-power wind turbine carrier,and their simulation and analysis were carried out with Huazhu CAE software.Finally,a non-riser casting process schemes was determined.Using the schemes,with the quality control in key aspects,QT700-2 high-power wind turbine carriers were…
Collagen was extracted from air bladder,agar were used as the gelling agents,Oolong tea as the deodorization agents and flavor enhancement to investigate processing technology of a new air bladder collagen jelly with tea flavor.The proportion of air bladder collagen and tea extraction,the mass concentration of agar an…
The grafting copolymerization of butyl acrylate(BA) onto poly(vinyl chloride)(PVC) were conducted through the method of activators regenerated by electron transfer atom transfer radical polymerization(ARGET ATRP) in aqueous phase,using PVC with different labile chlorine contents as the initiator,anhydrous CuCl2/tri(2-…
