Matriptase is a type II transmembrane serine protease highly expressed on the surface of tumor cells and participated in a range of human cancers including those of the breast, cervix, ovaries, prostate, colon and gastrointestinal tract. In this study, we developed a new matriptase detection probe with gold nanopartic…
This paper presents a design method for non-skewed small and medium cage induction motor based on the finite element analysis, in which the approaches of asymmetrical rotor slots, closed slots, nearly slot combination and reasonable air-gap length are adopted and studied systematically. With this method, the cage indu…
Manufactured nanoparticles are a new class of substance, and can be made from almost any solid material. typical examples include silver particles used as an antibacterial and antifungal agent in water bottles, zinc oxide used to block UVA and UVB sun rays in sunscreen, and the various materials used as pigments in pa…
Nanocrystalline (Ni0·5Zn0·5)xCo1−xFe2O4 with 0⩽x⩽1·0 are prepared by spraying co-precipitation method. Their microstructure and magnetic properties are investigated. The results show that nanocrystalline (Ni0·5Zn0·5)xCo1−xFe2O4 ferrites are spinel phase. Coercivity and retentivity of specimens increase with cobalt con…
SiC/0~20% graphite (volume fraction) composites were successfully fabricated by pressureless sintering at 1700 °C for 2 h in nitrogen atmosphere. The impregnating and heat treatment process for the samples with silica sol/phenolic impregnant was carried out at 1450 °C for 2 h in nitrogen atmosphere. The Vickers hardne…
According to the stress state and importance of cylindrical deputy campaign latch, NO. 2 cylindrical deputy campaign latch was selected as research subject. The work including design , processing, finite element load calculation, friction force before and after corrosion of similarity samples were carried out accordin…
In this context, a small scale cluster system for computational fluid dynamics (CFD) platform OpenFOAM is constructed, then a turbulent combustion case is simulated on the small scale cluster system. After the simulation is done, we can draw a conclusion with data that the effect of three-dimensional flow field is ach…
In this paper the voltage dependent occupation of states and their filling dynamics is investigated in two terminal device structures (Schottky barrier diode, p/n junction) by capacitance voltage (C-V) and deep level transient spectroscopy (DLTS) methods. Frequency scanned DLTS (FS-DLTS) was used, where the DLTS signa…
As shown by Prieto-López and Barrera (pp. 1110–1118), highly anisotropic metamaterials can be used to construct simple and efficient diffuse-light refractive collimators. - Decades have passed since the first theoretical studies about negative refraction appeared, but the topic has never been so active. Experimental e…
Poly(n-butyl acrylate) grafted silica nanoparticles were compounded with poly(methyl methacrylate) to yield silica/polymer composites with the improved dispersion of silica and interfacial adhesion with the matrix, thus showing increases in storage modulus and glass transition temperature.
In this paper, based on peculiar electromagnetic characteristics of metamaterials, peculiar properties of ridge waveguide with substrates of metamaterials with zero index of refraction are analyzed. These results provide some interested insights for potential applications.
The chemical composition of the sinter obtained without Bakal siderite concentrate in the batch is calculated. The influence of Bakal siderite in the batch on the sinter composition is assessed. The sinter content in the blast-furnace batch, the MgO content in the slag, the slag yield, and the slag basicity are plotte…
PURPOSE: To improve the image quality of radiotherapy planning CTs for patients with metal implants or fillings by completing the missing kV projection data with selectively acquired MV data that does not suffer from photon starvation. Using both imaging systems that are available on current radiotherapy devices, stre…
In the paper a Preisach hysteresis model is applied to determine the dynamic behavior of a steel column with a mass on the top and loaded by periodically alternating force. The column is considered as a completely rigid element, while the fixed end of the column is modeled with a rotational spring with hysteresis char…
The structural state of the cubic Zn0.999Fe0.001S single crystal grown by the chemical transport method has been investigated using thermal neutron diffraction at 300 K for the first time. It has been found that the diffraction patterns of the crystal contain diffuse scattering regions with wave vectors q = 0 and $$q…
The geometric structure, band structure and density of state of pure and Ag-N, Ag-2N codoped wurtzite ZnO have been investigated by first-principles ultrasoft pseudopotential method in the generalized gradient approximation. These structures induce fully occupied defect states above the valence-band maximum of bulk Zn…
Planar capacitor sensors have been widely used for measuring of very fast transients overvoltage (VFTO). A dielectric window made of epoxy was proposed to reduce the time required for installation of the sensor. The thickness of the dielectric window was calculated to provide a SF6pressure durability, and the frequenc…
The low temperature operation of GaAs solar cells incorporating a superlattice of InAs quantum dots (QD) was studied to explore carrier removal mechanisms. Dark current-voltage characteristics of QD devices did not show a temperature dependence, which suggests a tunneling-dominated recombination mechanism. Two-photon…
Highly conductive and transparent TiO2 nano films have been deposited by R.F. magnetron sputtering method on glass substrates. The influence of argon gas pressure on deposition rate, electrical performance and surface morphology has been studied through the ellipsometric thickness gauge, scanning electron microscopy a…
ALD-Co(W) was found to have a potential to replace the conventional PVD-Ta/TaN bi-layer in further shrinking interconnects as a single-layered barrier/liner material. We could confirm good barrier property of CVD/ALD-Co(W) film by BTS-TVS method after 350°C annealing. ALD-Co(W) showed lower resistivity of 60 μΩ-cm and…
