We have performed a high pressure synchrotron X-ray diffraction study of the ionic salt, cesium fluoride (CsF), up to 120 GPa. We observed the B1 → B2 phase transition near 5 GPa as previously reported. Beyond this pressure, no phase transitions were determined to have occurred up to the highest pressure studied. Unit…
The ZrO2 thin film was grown using pulsed laser deposition (PLD) method and irradiated with 60 keV Kr+ ions. The as-prepared and ion irradiated ZrO2 thin films were characterised with high resolution transmission electron microscope(HRTEM). The as-prepared ZrO2 thin film was found to be monoclinic in structure. Upon 6…
The effects of having a nanopatterned photonic crystal (PC) structure in the surface of a solar cell can be usefully employed to increase the energy conversion efficiency, which may be critical for space applications. In this work, we have measured the reflectance (R) and transmittance (T) of thin InP layers (270 nm t…
Semi-organic lithium hydrogen oxalate monohydrate non-linear optical single crystals have been grown by slow evaporation solution growth technique at 35 °C. Single crystal X-ray diffraction study showed that the grown crystal belongs to the triclinic system with space group P1. The mechanical strength decreases with i…
The topological and energetic properties of the electron density distribution ρ() for the tin-ligand interaction in di-n-butyltin(IV) derivative of glycyltryptophane (H2L) (n-Bu2SnL), the geometric configuration of which was optimized at B3LYP/3–21G/LANL2DZ(Sn) level of theory, have been theoretically calculated at th…
We have investigated strain mediated magnetoelectric coupling and ac impedance properties of 0.5NiFe2O4-0.5PbZr0.58Ti0.42O3 nanocomposite at room temperature. The magnetoelectric voltage coefficient has been calculated from ME voltage for both transverse and longitudinal direction at a frequency of 37 Hz. The magnetoe…
利用壳聚糖(CTS)良好的成膜，抑菌性和L-半胱氨酸(L-cys)良好的抑菌，抗氧化性，通过化学改性法制备了巯基含量高达333 μmol/g的L-cys改性CTS (CTS-cys)。采用抑菌圈法研究了CTS、L-cys和CTS-cys对大肠杆菌、蜡样芽孢杆菌和金黄色葡萄球菌的抑菌效果。实验结果表明：在被测试范围内，L-cys对三种菌株均有很好抑菌性；CTS-cys对大肠杆菌、金黄色葡萄球菌均有较好抑菌效果，最大抑菌率为89%，92.9%，对蜡样芽孢杆菌的最大抑菌率只有60.5%；CTS对三种菌株的最大抑菌率均在50%水平以下，抑菌效果差。壳聚糖半胱氨酸衍生物很大程度上协同了半胱氨酸的抑菌性，大大提高了壳聚糖的抑菌能力。 The…
Zn3V2O8 phosphor nano particle was synthesized by modified sol-gel method using citric acid as chelating agent and ethylene glycol as a binder. The properties of synthesized nano particle were characterized by powder XRD, FTIR, SEM and PL analysis to understand structural formation, organic liberation, surface morphol…
Layered braided composite is widely used in structures. The mechanical analysis of this material is more complicated than that of laminated plate composite materials, so the accurate solution of structure made of this material is fairly difficult to obtain. In this paper, a simplified FEM model is used to analyze the…
We report the soft X-ray absorption spectroscopy (XAS) on pulsed laser deposition (PLD) grown epitaxial BaTiO3 thin film on (001) oriented SrTiO3 substrate. X-ray diffraction studies confirm that film is grown along the [001] direction and is compressed along surface normal. XAS around O K edge and Ti L3,2 edges perfo…
We report the effect of oxidation on the structural, vibrational, magnetic and electrical properties of Fe thin films deposited at ambient temperature directly on silicon substrate using magnetron sputtering technique and post annealed (TA) under air atmosphere. The structural and vibrational properties reveal that as…
Samples of Al2O3/MgO composite with various MgO weight contents were synthesized at high temperature in vacuum. Its phase composition, density and grain size distribution depending on the synthesis temperature and MgO quantity were studied. Composite luminesciense with electron beam excitation was registered.At the re…
In order to prevent the maloperation of the transformer differential protection device affected by transformer magnetizing inrush current and internal short circuit fault current, the device should be able to identify the internal fault current and inrush current. Accordingly, this paper is aimed at adaptive transform…
By taking a certain type of rocket launcher structure as the research object, its loading analysis was carried out. By applying the ANSYS as a tool and by combining a typical working condition to carry out finite element analysis (FEA), the deformation and the stress values under the work condition were obtained, and…
The hydrogen permeability of Pd–Ag alloy membranes has been investigated over a wide temperature range between 100°C and 500°C. The hydrogen permeation coefficient, Φ, for Pd–23 mol%Ag decreases with decreasing temperature above 300°C, in good agreement with the previous literature. However, Φ starts to increases belo…
EN 9 (AISI 1015) is a low carbon steel having general engineering applications that includes blades for axes, knives, and sickles as well as shafts, bushes, crankshafts, screws and wood working drills. In normalised condition, it can be used for gears, sprockets and cams. The purpose of heat treatment is to soften the…
A new methyl-embedded (3,36)-connected txt-type metal–organic framework, {Cu2(DCPEMP)·H2O}n (NJFU-4, H4DCPEMP = 3,5-bis(3,5-dicarboxylphenylethynyl)-4-methylpyridine), was solvothermally synthesized and structurally characterized, which exhibits a BET surface area of 2160 m2 g−1, high stability and high H2 uptake capa…
Cathodoluminescence spectroscopy in a scanning transmission electron microscope is used to probe the spatio-spectral response of nanospiral aperture plasmonic vortex generators. Further, we demonstrate that plasmonic vortex modes can probe the chirality of nanoscale materials.
Upon exposure to visible light, controlled multiple dose protein release was demonstrated by using a microspherical depot composed of biodegradable poly(ε-caprolactone) (PCL), bovine serum albumin (BSA) or horseradish peroxidase (HRP) as model protein, polymer-coated gold nanoparticles as photothermal component, which…
