Based on the Monte Carlo calculation method, geometric model of spent fuel storage pool Area I of small modular reactor is established, assuming infinite 6×6 type storage racks. Calculation results show that the reactivity is maximal when the water density is 1.0g/cm3. The value of keff is 0.8729 in normal storage con…
CdSe semiconductor nano crystals (NCs) and Polyaniline (PAni) are mixed uniformly to prepare CdSe NCs/PAni complex. PAni can quench the fluorescent signal of CdSe NCs. The fluorescent intensity of CdSe NCs/PAni complex is related to the size of CdSe NCs and concentration of PAni. Ultraviolet visual (UV-Vis) absorption…
In this study, an analytic approach is presented for the graphene-based cloaking of conducting finite wedges with an arbitrary angle of opening in the terahertz (THz) spectrum. We show that a periodic array of graphene nanopatches reduces scattering significantly for all angles of incidence. The analysis is based on L…
This paper describes an alternative way of determining the tension in a conductive wire with two fixed ends.
The objective of this study is to investigate appropriate configuration used for micro direct methanol fuel cells (DMFCs). We designed grid and spiral flow fields of electrode plate and simulated with ANSYS. Using silicon-based micro–electro–mechanical systems (MEMS) technology to fabricate the DMFCs with different fl…
The nanosized magnesium hydroxide is a valuable intermediate for chemical industry materials. This review covers the preparation methods of nanosized magnesium hydroxide using concentrated seawater or brine as raw material, including alkaline method, calcium method, ammonia method and other new methods. Additionally,…
The influence of minor Mo addition on the lattice misfit and creep rupture strength of a new single crystal superalloy have been investigated. It was shown that Mo can reduce the lattice misfit; increase the tendency of forming TCP phase; extend the time to material failure.
In the last four years, our group has played a pivotal role in the discovery of >20 new susceptibility genes for Alzheimer's Disease. These genes include PICALM and BIN1, both of which are involved in clathrin-mediated endocytosis. In a recent publication Xiao et al (2012) reported that the manipulation of PICALM expr…
We conduct first-principles total-energy density functional calculations to study the ScB2 (0001) surfaces. The optimized surface structures and electronic properties are obtained. The results show that Sc-terminated surface is thermodynamically more favorable in most of range. The relaxations indicate that it is main…
The electromagnetic problem consisting in the interaction between a elemental point source and a resonant metasurface is investigated. A recently introduced semianalytical approach is adopted to take into account all the propagating and evanescent waves which constitute the spectrum of the point source and all the pro…
We analyze, analytically and numerically, optical properties of plasmonic nanowire composites that form a promising platform for nanophotonics, present description of nonlocal electromagnetism in this media, and discuss implications of nonlocal response for different applications.
In this paper, we show that the field emission current of carbon nano-fibers (CNFs) is significant improved by introduction of a thin nickel layer on the cathode. Carbon nano-fibers were synthesized by chemical vapor deposition using Pd as catalyst on a 304 stainless steel filament that electroplated with a thin nicke…
The parallel crackswere prefabricated on both sides of theQ345 steel specimensand the tensile failure tests were performed.The effects of parallel crack spacing and crack length on the crack propagation behavior were studied and the fracture modes were investigated with electronic scanning microscope.The finite elemen…
Thin-film transistors based on anodized indium-tin-oxide (ITO) active layer and anodic tantalum oxide (Ta2O5) gate dielectric were investigated. The electrical and optical properties of ITO film can be affected by an anodization treatment. The anodized ITO TFT shows an on/off current ratio of 108, a saturation mobilit…
Novel nanobranched Ni/Fe-LDHs were successfully prepared by coprecipitation method without adhesive condition. The effects of different factors as pH and aging time on its morphology were discussed in detail. According to the results, the branches diameters of Ni/Fe-LDHs are among 50-100nm and the optimum experiment p…
An appropriate ultrasonication of collecting foreign recombinant protein (human-adiponectin) from yeast was established. Regarded the bioactivity of foreign recombinant protein tested by Western Blotting analysis as parameter, a L9(33) orthogonal array design based on a series of single-factor experiments was employed…
Silver nanoclusters synthesized using aptamer as matrices attracted more attention in the fields of medicine, pharmacology and biology. In this paper, we report a novel approach to sgc-8-C8-templated formation of fluorescent Ag nanoclusters and its application to bioimaging. This was further confirmed by flow cytometr…
Holographic data storage based on polarization techniques is proposed. Angular and shift multiplexing techniques, as well as polarization multiplexing, are developed to increase storage capacity. Some experimental results are presented.
Fir tree groove broaching rebound has an obvious impact on the wheel groove manufacturing accuracy. The prediction of wheel groove rebound in the broaching process is an important aspect to improve the manufacturing precision of wheel groove. The deformation caused by cutting force is the main factor that decides whee…
An novel intermediate of (4-Iodo-phenyl)-(4-trifluoromethyl-phenyl)-diazene for azobenzene liquid crystal was synthesized. 4-Trifluoromethyl-phenylamine as raw material was oxidized by Oxone (Potassium peroxymonosulfate) in CH2Cl2/H2O solvent to synthesize 1-Nitro-4-trifluoromethyl-benzene (m1). The effect of Oxone am…
