This paper reports on a study of the influence of oxygen deficiency on the magnetization, paramagnetic susceptibility, electrical resistivity, magnetoresistance, and volume magnetostriction of the La0.9Sr0.1MnO3 − y manganite with y = 0.03, 0.10, and 0.15. The magnetization M(T) behaves in a complex way with temperatu…
PURPOSE: Reduced or delayed neovascularization is a major obstacle with regard to tissue-engineered constructs. The aim of this study was to evaluate the early microvascular response to a novel degradable ε-caprolactone terpolymer matrix. METHODS: ε-caprolactone terpolymer matrices (Suprathel Plus®; Institute of Texti…
Pattern recognition receptors ( PRRs ) are typical immunoreceptors of the organismal innate immune system,being vital to the survival of organisms. In present study,Bombyx mori genes encoding 14 PRRs were cloned and identified,including 10 for peptidoglycan recognition proteins (PGRPs) and 4 for β-glucan recognitionpr…
The damage evolution in three dimensional carbon fiber reinforced silicon carbide (3D Cf/SiC) composites in a stressed oxidation environment was investigated by scanning electron microscopy in terms of generation and propagation of cracks. The results indicate that the main damages in 3D Cf/SiC composites in the stres…
The effects of fly ash on the property of MgO cement were investigated by determining expansion,analyzing hydrated products and pore structure of cement paste,and then the mechanism was also discussed.MgO expansion is restrained greatly by fly ash,almost completely restrained if the content of fly ash is over 20%.Fly…
Active magnesium oxide was prepared by thermal decomposition method using Mg(OH)2 as raw materials.X-ray powder diffractometer,scanning electronic microscope,mercury intrusion porosimetry and thermal analyser were employed to characterize the powders.The results show that Mg(OH)2 decomposes to MgO by one step with a t…
To investigate the risk of free metallic particles in gas insulated switchgear(GIS) chamber,a test cell is designed for simulation.Ultrasonic signals generated by the free particles with different shape and size are detected to extract the feature parameters such as power frequency phase correlation,amplitude and flig…
Article Theoretical Analysis and Experimental Verification of the Effect of Surface Tension on Morphology of Nanofibers in Bubble Electrospinning was published on August 1, 2010 in the journal International Journal of Nonlinear Sciences and Numerical Simulation (volume 11, issue 8).
摘要 采用高温固相法合成发光样品Y2O3：Eu3+0.01和Y2O3：Eu3+0.01，Dy3+0.01.X射线衍射分析(XRD)表明样品保持Y2O3晶格结构，掺入的Eu3+和Dy3+对Y2 关键词: 长余辉 / Y2O3 / 稀土掺杂 / 陷阱 Abstract The rare-earth doped phosphors Y2O3：Eu3+0.01and Y2O3：Eu3+0.01, Dy3+0.01 were synthesized by a high temperature solid-state reaction method. The phase structures of the phosphors were cha…
Collagen is the most abundant protein of animal origin, comprising approximately 30% of total animal protein. There are at least 19 variants of collagen, named type I to XIX. Types I, II, III and V are the fibrous collagens. Type I collagen is found in all connective tissue, including bones and skins. It is a heteropo…
The effects of nanohydroxyapatite/gelatin (nHA/G) ratio, stirring rate and water/oil phase ratio (W/O ratio) on particle size and distribution of nanocomposite microspheres based on nanohydroxyapatite-in-gelatin were investigated. Surface response model was used for tests design. The microspheres were fabricated using…
An orbital ordering effect is observed in YbVO 3 around 170 K while the crystal structure is orthorhombic (space group pnma) . A monoclinic transition has been reported below T N = 104 K, while according to recent specific heat measurements, it occurs at 170 K. The crystal structure of YVO 3 at 300 K is also orthorhom…
The stability of three ultrathin TiO(x)/Pt(111) films with different stoichiometry and defectivity and the corresponding Au/TiO(x)/Pt(111) model catalysts in CO or a CO-O(2) (1 : 1) gas mixture up to a pressure of 100 mbar has been investigated. According to previous studies, the ultrathin films proved to be effective…
An oxamato-based compound of formula [ttf]2[Cu(opba)]·H2O, with ttf = tetrathiafulvalene and opba = ortho-phenylenebis(oxamato), has been prepared and characterized. The complex was obtained by metathesis from (ttf)3(BF4)2 and (Bu4N)2[Cu(opba)] in acetonitrile at room temperature. The UV-Vis-NIR spectrum reveals the p…
Oxygen content in the pure Silicon crystal is inevitable because of the significant rate of corrosion of the crucible walls at high temperature. Precise control of oxygen is possible only by manipulating underlying flow. A global model was developed to investigate the effect of crystal and crucible rotations in absenc…
The 4-(trans-4′-n-hexylcyclohexyl)-isothiocyanatobenzene (6CHBT) nematic liquid crystal was doped with single walled carbon nanotubes (SWNTs) and with magnetite labeled single walled carbon nanotubes (SWNTs/Fe3O4). Prepared samples were characterized by infrared spectroscopy, transmission electron microscopy, optical…
Polypropylene electrets 20 μm thick charged in a negative corona were studied. The samples were charged to different initial surface potentials and were stored under various pressures for 30 minutes. Then, the surface potential was again measured. The dependence of the electret surface potential on the pressure, under…
Halocynthia roretzi, a solitary ascidian, can swell and deflate its solid, leather-like tunic largely, but it is not clear whether the tunic deforms actively. Cellulose Iβ, which is predominant in higher plants, is also present in the tunic as a highly crystalline form. The elastic modulus of its whisker crystalline i…
Drug release and its relationship with kinetic and thermodynamic parameters of drug sorption onto poly(lactic acid) (PLA) fibers have been studied using Diclofenac, 5-Fluorouracil (5-FU) and Metformin as model drugs. The sorption method is more flexible and avoids the damaged drugs, remaining toxic organic solvents an…
The development of a corium pool in the lower head and its behavior is still a critical issue and is of great importance to assess the severe accident progression consequences to ensure the nuclear plant safety. Therefore, experimental efforts are a vital element of the assessment process, providing hard data and insi…
