SBA-16 type mesoporous molecular sieves due to their special physical and chemical properties have been a subject of intense research.The catalytic activity of SBA-16 is able to effectively increase by modified using metal.In this paper,based on our researches on SBA-16,the synthesis of SBA-16 modified by metal using…
E-20 epoxy resin is curing with polyamide resin and cardanol modified phenolic amine,respectively.The paint films were insolated respectively and the chromatism was detected;film performances were detected after ultraviolet irradiation.It was found that cardanol modified phenolic amine has faster rate than polyamide t…
The resonant mode characteristics of a planar microcavity composed of single-negative materials(SNG) are studied with the transfer matrix method.It shows that the resonant frequency is mainly determined by the material parameters and structure parameters of the dielectric in cavity.However,the line width(FWHM) is affe…
Static strength tests of notched aluminum alloy panels repaired with bonded composite patch were conducted to determine the load-displacement curves and to understand failure mode and mechanism as well as to investigate the effects of the behaviour of adhesives,mechanical properties and thickness of composite patch on…
Based on crystalline electric field(CEF) theory,we simulated the temperature dependence of inverse magnetic susceptibility measured by Kaczorowski group before.We obtained CEF splitting levels and corresponding wave functions for rare earth compounds Ce3Rh2X2(X=Ga,Ge).The first excited and the total excited energies a…
PP/wollastonite blends was prepared by mechanical blending,and its tensile strength,impact strength and fracture morphology were tested and analyzed.In this study,elastomer EVA and SBS was added into blends to increase its toughness;MAH was also added into blends to improve its interfacial bonding force.Results showed…
Sulfobutylated cellulose ether(SBC)was synthesized with cotton pulp(cellulose)and 1,4-butanesultone(BS)as raw materials.The structure of SBC was characterized by means of FT-IR,13 CP MAS,SEM,and XRD.The effects of degree of polymerization of cellulose,mol ratio of raw materials,reaction temperature and reaction time o…
In this paper,modified nano-magnesium hydroxide(MNMH) was prepared with NMH grafted by silane KH-550,then the PA6/MNMH nanocomposites were prepared by in situ copolymerization with the prescence of catalyst.The micro-structure and properties of PA6 nanocomposites filled with NMH,MNMH were characterized by means of FTI…
In order to get the smart textile with thermo-regulated property,two kinds of energy-storage materials was used to prepare the binary composite energy-storage sol by sol-gel process.The silicon-molybdenum blue method was adopted to study the adsorption behavior of the binary composite energy-storage sol to cotton fabr…
Levodesmethylphencynonate hydrochloride(1),a novel selective M4 muscarine receptor antagonist,has been chosen as a candidate of anti-Parkinson′s disease drug characterized by its good efficiency,high selectivity and low toxicity.A new synthetic method in the search for more economical and environmental friendly proces…
The Au nanoparticles/cystamine/glassy carbon electrode was fabricated by self-assembling nanoparticles on GCE modified with cystamine.The electrochemical behavior of electrode was studied by cyclic voltammetry and electrochemical impedance spectroscopy.The result showed that the modified electrode had good electrochem…
ZnO rod arrays were directly grown on glass substrates by homogeneous precipitation using an equimolar aqueous solution of Zn(NO3)2 and C6H12N4.The influence of the solution concentration,reaction time,and reaction temperature was investigated by the orthogonal experiment.The different performance was characterized by…
