Iron–chromium cyanide molecular magnet nanowire arrays have been fabricated on anodized aluminum oxide templates by electrochemical technology. The selectable lengths and diameters of the nanowires can be obtained by controlling the size of pores on the template. The result of transmission electron microscopy indicate…
Numerical simulations of the solid-liquid phase change of bismuth with a free surface are carried out under different gravity conditions. A multiphase approach using the Volume Of Fluid (VOF) method over a fixed grid is used to solve the thermocapillary induced flow of the melt and gas phases. The dynamics of the gas…
We demonstrate a method for enhancing the laser efficiency by stacking multiple dye-doped chiral polymer films. No laser emission was observed from a single 8 mum film. By stacking two films together, the laser efficiency is dramatically enhanced. Further increasing the number of stacked films, the output laser power…
Gas insulated transmission lines (GIL) are a means of bulk electric power transmission at extra high voltage. GIL consists of tubular aluminium conductors encased in a metallic tube that is filled with a mixture of sulphur hexafluoride and nitrogen gases for electrical insulation. Since the first installation of GIL i…
In order to develop a reaction rate equation for the high concentration CO2, the regeneration reaction of CaCO3 was examined for the corresponding pressure condition in the temperature range 1123–1193 K. It was observed that the reaction rate was controlled by CO2 diffusion during the initial period and thereafter by…
Spray forming is an advanced technology for the manufacture of homogeneous material from the melt. In this study, 20MnCr5 steel, a typical case hardening steel for gear and shaft production, has been spray formed and hot worked to semi-finished bars. Shaft-like specimens have been made from the spray-formed material f…
We have automatized the calculation of band structures. Using a rigid band approach and Boltzmann theory it is possible to calculate the Seebeck coefficient and effective mass of a given compound at varying carrier concentrations. One can therefore rapidly screen a material for potential thermoelectric applications. T…
The chemical strengthening of Li2O•2SiO2 transparent glass-ceramics was investigated. The fracture strength of glass and glass-ceramics increased first and then decreased, and the crack formation and peeling of ion exchanged layer were observed for both Li+↔Na+ and Li+↔K+ ion exchange. This suggests that the submicros…
With two hydrazide motifs installed at one edge, a novel supramolecular system self-assembled into a polymeric zipper-like structure via two hydrogen bonds at each knot, both in solution and in the solid state.
Cathodic reduction of a strontium bicarbonate bath stabilized by a variety of amine-carboxylic acids as ligands resulted in the deposition of micrometers-thick coatings by electrogeneration of base. The use of diethylenetriaminepentaacetic acid (DTPA) yielded coatings with a distinct -axis orientation. The degree of o…
Magnetic core has major effects on the response of transformers at low frequencies. For better understanding of transformer behaviors and modeling them accurately, it is necessary to study core behaviors and their effects on transformer current and voltage waveforms. For better studying core behaviors, it is possible…
In this paper, selected direct-current and high-frequency properties of dielectric textile materials for application to textronics are presented. Textronics deals, among other matters, with designing and manufacturing devices which are at the boundaries of electronic and textile science and technology. Textronic mater…
A well established method for scale removal on hot rolled wire rod is pickling. To avoid pollution problems, the wire rod can be mechanically descaled. By this method, the removed scale can be reci ...
Efforts have been made to investigate a treatment process that produces minimum effluents (i.e., environmentally friendly), and yet significantly increases the quality and heat resistance of a fibrous collagen material for the leather industry. The structural properties of collagen fibrils in chrome tanned bovine leat…
Aggregate formation in axenic and microbial co-inoculated batch cultures of Aulacoseira granulata (Bacillariophyceae). Aggregate formation involving diatoms is a well-known process, especially in the marine environment. The aim of this paper was to observe natural aggregates formation in axenic and microbial co-inocul…
Glycolysis of poly(ethylene terephthalate), PET, waste using trimethylol propane (TMP) or pentaerytheritol (PEr) was used to produce suitable hydroxyoligomers for polyurethane foams. The glycolysis was carried out in the presence of manganese acetate as a catalyst, under high and normal pressure atmosphere in xylene a…
As principal product to prevent pollution flashover for overhead transmission lines,composite insulators are applied to power networks in large quantity,but existing detection methods cannot effectively detect the inner-defect of composite insulators,so that the inner-defect becomes hidden danger to secure operation o…
Dynamic Behavior of reactive powder concrete(RPC) is studied by using a split Hopkinson pressure bar.At static state and dynamic state with different impact velocities,a series of compress tests of plain RPC,RPC containing polypropylenefiber and RPC containing steel fiber were carried out.The influence of transverse c…
The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) was founded with the aim to promote scientific cooperation in the area of construction materials and structures worldwide. This mission is achieved through collaboration of leading experts in construction prac…
The deformation behavior of a magnesium alloy tube during press bending is investigated to clarify the effect of the difference between tensile and compressive stress-strain curves of magnesium alloy experimentally and theoretically. The bending experiments using a mandrel of wires are carried out at room temperature.…
