The creep behaviors of rice hull flour/PP composite under different stress levels were studied through bending test. The results show that the bending creep behaviors of rice hull flour/PP composite have obviously correlation to the stress levels. Based on the time-temperature-stress equivalence principle and 15% stre…
In order to investigate the supramolecular assembly and interfacial coordination of special amphiphile, two Schiff Base compounds with alkyl chains and different azobenzene substituted groups were designed and synthesized, and their supramolecular assembly and interfacial properties were investigated by spectral and m…
A way to generate a loss curve for modern high-voltage reactive power sources on the basis of magnetically controlled shunt reactors is presented. The loss curve is generated on the basis of rated values for the components of this equipment.
Acoustic cavitation plays a key role in several fields including therapeutic medicine and cleaning. Meanwhile, acoustic cavitation is a hazardous phenomenon due to the damage to targets irradiated by ultrasound such as normal cells in the human body. Therefore, it is important to control cavitation. An accurate techni…
In order to evaluate the feasibility of tritium recovery from tritiated water by thermochemical decomposition using ZrNi5, the kinetics of reaction between ZrNi5 and water vapor was studied by thermogravimetric method in the temperature range from 673K to 823K. The result shows that reaction rate increased significant…
In this study, photoconductive detector of nanowire-based devices have been fabricated by aligning ZnO nanowires across paired Au electrodes using dielectrophoresis. The Ag nanoparticle (NP) decoration as an effective way to enhance the maximum responsivity, and cut down the response time of the traditional region ZnO…
One of the most significant current discussions in insulation materials is the influence of space charge on electrical ageing processes. The space charge observed under both dc and ac high voltage makes the role of space charge in electrical ageing increasingly difficult to ignore. A considerable amount of literature…
One or a series of continuous stirred tank reactors (CSTR) is adopted in material engineering. The first esterification reactor and the final stage polyeondensation reactor are very significant，which operation affect the quality of output directly. The influence of operational variables is discussed separately. Toward…
Using FX-4000 strain unit, the apoptosis of Human oral Squamous Cell Carcinoma KB Cells that underwent different mechanical strain were studied. Flow Cytometer was adopted to investigate the apoptosis of Human oral Squamous Cell Carcinoma KB Cells. Experimental results indicated that cell apoptosis rate increased sign…
The research and development of new VUV scintillators includes also LuLiF4 single crystals doped by${\hbox{Nd}}^{3+}$. Due to their lower light yield, the${\hbox{Gd}}^{3+}$codoping is studied as a tool to improve an energy transfer from the host to${\hbox{Nd}}^{3+}$emission centers and increase the light yield consequ…
We evaluated the photodetection properties and external quantum efficiency of graphene-silicon Schottky photodetector under IR illumination for 700 nm, 1.1 μm, 2 μm, and 3.5 μm wavelengths at room temperature. The graphene-Si Schottky diode has been fabricated by depositing mechanically exfoliated HOPG on top of the p…
Al-doped TiO2thin films grown on Si(100) by atomic layer deposition has been investigated as a potential high dielectric constant insulator in the application of microelectronics. The film thickness is determined by spectroscopy ellipsometry and transmission electron microscopy. X-ray photoelectron spectrometry is use…
The finite element method (FEM) was used to simulate the sliding wear progress. The stress field and strain field of Cr-Mo-Cu alloy cast iron with nano-additives under wear abrasion were analyzed through experiment and numerical investigation in this paper. And then the wear depth was got by calculation for different…
Abstract Die Schichtabscheidung über Magnetronsputtern ist Bestandteil wichtiger Prozessschritte bei der Herstellung von CIGS‐Dünnschicht Photovoltaikmodulen. Diese basieren auf dem Halbleiter Cu(In, Ga)Se2 und erfordern einen Rückkontakt aus Molybdän. Herstellung und Anwendung von Sputtertargets aus Molybdän, MoNa un…
For the last 100 years ASTM Committee C07 (Lime) has provided guidance to the lime industry and its customers related to the methods of testing and specifications for limestone and lime products and their applications. A broad range of lime user, producer, and general interest input was provided and refined through a…
The piston is one of the major components of the motor fuel that serves as a component of the intake air pressure and the recipient of the combustion pressure in the combustion chamber. This component is designed to be lightweight and resistant to pressure. In addition to the selection of appropriate materials, select…
As the increase of concern for global warming, high volume mineral admixtures(HVMA) concrete for the reduction of carbon dioxide which is occurred production of cement has low cement, it is reported that use of inorganic activators for increase of compressive strength. As use of high content of mineral admixtures, sin…
