Wormhole-shaped F-doped TiO2/Ti photoelectrodes were prepared by microarc oxidation method in NaF solution. The morphology and structure of the photoelectrodes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF). It was found that F-doped TiO2/Ti photoelectrod…
In order to understand the mechanical properties with the blended ratio of soybean protein fiber/polyester blended fabric，six blended fabrics are chosen and tested. The results indicate that the strength and the bending rigidity of the blended fabric decreased，the drapability has no notability changed and the longitud…
The inverse scattering problem has been solved for protein complexes whose surfaces can be described by a set of the simplest doubly connected surfaces in the uniform approximation (a scattering potential inside the molecule is a constant). Solutions of two proteins—well-known GroEL bacterial chaperonin and poor-studi…
Diffusion-induced growth of a two-dimensional cavity (a pore) in a monolayer of adsorbed atoms (adatoms) on the crystal surface is considered in the case of the vacancy mechanism for diffusion in the monolayer. In the case in which the cavity radius is smaller than the typical diffusion length of vacancies, the stabil…
Bio-organic materials such as bones, teeth and tendon generally show pyro- and piezoelectric activity that implies the existence of macroscopic polarity. The first discoveries date from 19571in the bones and tendon of both humans and animals and has led to the suggestion that the presence of spontaneous polarity might…
We present a cheap and versatile method to fabricate antireflective moth-eye structures on various substrates. This method consists of a mask created by a self-assembly technique (block copolymer micelle nanolithography - BCML) and a subsequent reactive ion etching step. Contrary to most other methods this technique a…
Measurement of the energy consumption of isolated cardiac trabeculae requires highly sensitive temperature sensors. In this paper we describe and characterize an initial prototype of a vapor pressure thermometer being designed and built for application to muscle microcalorimetry. The device exploits the change in vapo…
Mullite/corundum composites synthetized by sintering with bauxite as raw material was researched. The sintering temperature, main crystal phase, microstructure and fracture mode of the composites synthetized by sintering are different with change of ratio of Al2O3 and SiO2 and content of Al2O3: (1) If the ratio of Al2…
A sensitive immunoassay based on immunomagnetic beads for measuring carcinoembryonic antigen (CEA) concentration in cancer cells was presented in this article. We used immunomagnetic beads to separate CEA in the gastric cancer cells and those CEA could be marked with horseradish peroxidase (HRP) labeled anti-CEA secon…
Semiconducting electroluminescent polymers have been the subject of several studies due to its great success on Polymer Light-Emitting Diodes (PLEDs) and the potential to be applied commercially on Photovoltaic Cells and Field Effect Polymer Transistor1. However, fundamental points are still under development and need…
This paper presents a semi-analytical method to computer the air gap magnetic field of direct drive permanent magnet (PM) torque motors for being evaluated slotting effects accurately. The field region is divided into the smooth air gap region and the extended slot sub-regions. The magnetic vector potentials in the ai…
Elaborated characterization tools play an important role for the further improvement of solar material and the development of solar cells. Besides the huge variety of highly advanced methods mainly based on optical and electrical measurements, the direct measurement of surface currents by the detection of their induce…
The surface of wood/polyethylene (PE) composites were treated by mechanical polishing treatment and coating treatment, and the structure of surface for wood/PE composites before and after treatment was characterized by fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) in this paper.…
Temperature characteristics are essential to reasonable application of Ni-Mn-Ga alloy. This paper reports an experiment equipment which is used as the research of variable temperature effect. The relationship between deformation rate and temperature is studied. Dynamic and static experiments are done. The results show…
The dissolve behavior and cathode protection performance of Al-Zn-In-Mg-Ti anode was studied by electrochemistry impedance spectrum technology, weight-loss measurement and SEM in natural corrosion and self-discharge experiment. The results show that the 7A52 corrosion rate was decreased at a certain extent which under…
This paper introduces the topology of active power filter (APF) with three-level diode clamped and its principle. the paper analyses the space vector PWM (SVPWM) principle in detail. The traditional SVPWM algorithm requires a lot of calculation about trigonometric functions, and it needs to judge the sector. This pape…
A series of the carbon nanotubes were synthesized on quartz substrates in a chemical vapor deposition (CVD) process. Ethylene was used as the carbon source, and ferrocene used as the catalyst. The scanning electron microscope (SEM) and Raman spectrum were employed to investigate the effects of reaction temperature on…
The reactivity of zinc and copper oxide nanoparticles was investigated upon their interaction with iron oxides. It was ascertained that, depending on the reaction conditions, nanoparticles of zinc and copper ferrites (ZnFe 2 O 4 and CuFe 2 O 4 ) or core/shell nanoparticles (Fe 3 O 4 /ZnO) are produced. Size, compositi…
Based on the mixture theory, to clarify the mechanism of macro segregation of blooms, a mathematical model of macro segregation coupled with a heat transfer equation and a solute balance equation is developed. The software is built with VC++ as the program language to predict the process, which can simulate the temper…
This work is devoted to an investigation of the hardness ( H ), modulus of elasticity ( E ), and adhesion-cohesion strength of ion-plasma vacuum-arc coatings of the Ti-Cr-Al-N system. It is shown that the magnitudes of H and E are determined by the crystallite size and microdeformation level. The maximum values of har…
