As a popular energy absorber, steel box-sectional beams are widely used in various engineering structures. In this paper, the dynamic crushing behaviours of steel beams with box cross sections are investigated and outlined. Systematic parametric studies were conducted in order to study the effect of material propertie…
This article presents a performance analysis of a multi-cell integrated-planar solid oxide fuel cell (IP-SOFC) fuelled by pure hydrogen. A non-isothermal electrochemical model, taking into account the temperature variation produced by electrochemical reactions, air, and fuel flow, is used to predict the characteristic…
A new ion-pair complex, [BrClBzIQl][Ni(mnt)2](1) ([BrClBzIQl]+ = 1-(2′ -chloro-4′ -bromobenzyl)isoquinolinium, and mnt2− = maleonitriledithiolate) has been prepared and characterized by elemental analyses, IR, MS spectra, single crystal X-ray diffraction and magnetic susceptibility. The crystals are monoclinic space g…
Particle reinforced metal matrix composites(PR MMCs) have attracted extensive investigation in material science and engineering.They combine both strength and toughness and show excellent properties such as good wear resistance,corrosion resistance and high temperature properties. Laser depositing of metal matrix comp…
Abstract The kinetic regularities of the influence of low 1‐octene concentrations on its epoxidation by tert‐butyl hydroperoxide in the presence of molybdenum disilicide (MoSi2) as a catalyst were investigated. The minimum in the dependence of the initial rate of hydroperoxide consumption on 1‐octene concentration was…
In this paper, we analyze the birefringence effect in circular photonic crystals (CphCs). The studied CphCs are dielectric rings (DRs) and photonic crystals with cylindrical air holes arranged in circular patterns. The dielectric concentric circular patterns admit two preferred propagation directions defined by an ext…
Abstract Uncharged derivatives of thioflavin‐T have known in vitro and in vivo affinity for amyloid β. We synthesized and evaluated two derivatives with a fluorine‐18 labelled fluoropropoxy substituent either at the 6‐position or at the 2′‐position of the 2‐(4′‐aminophenyl)‐1,3‐benzothiazole core with the aim to get s…
We have investigated the thermopower in the organic compound $\ensuremath{\theta}\text{\ensuremath{-}}{(\text{BEDT-TTF})}_{2}\text{Rb}M{(\text{SCN})}_{4}$ $(M=\text{Zn},\text{Co})$ in both its normal and rapidly cooled states. The anomalous temperature dependence of the thermopower is found to extend into the rapidly…
Abstract A new organic‐templated aluminogermanate [C4H12N][AlGe3O8] (1) has been prepared under solvothermal conditions by using 2‐propanol as solvent. The structure of the title compound was characterized by IR spectroscopic, elemental analysis, TG, single‐crystal X‐ray diffraction and powder X‐ray diffraction. Compo…
Because of their low density,high strength-to-weight ratio and high damping capacity, magnesium alloys have gained increasing applications in many fields,especially for die-cast magnesium alloys.The application of die-cast magnesium alloys in structures and repair welding of casting defects necessitates the developmen…
Barium tungstate crystallites with different sizes and morphologies were successfully synthesized using a simple electrochemical technique by varying the components of electrolyte solutions. XRD analysis evidenced that the as‐prepared samples were a pure tetragonal‐phase of BaWO 4 with a scheelite structure. Scanning…
Mono- and binuclear metal-organic compounds bearing long alkyl chains were synthesized and studied at the liquid/graphite interface using scanning tunneling microscopy. Two different lamellar surface patterns as well as a star like structure were obtained driven by van der Waals interactions of the alkyl chains and we…
Abstract The crystallographic and magnetic texture of epitaxial, hard magnetic Sm2Co7 films prepared on Cr‐buffered MgO single‐crystal substrates are analyzed. Substrate symmetry, deposition temperature, and deposition rate are systematically varied, resulting in a variety of different, but epitaxial orientations. On…
A novel complex of Cu(pic)2 with V-shaped ligand 1,3-bis(benzimidazol-2-yl)-2-o- xopropane (OBB) was synthesized and characterized by elemental analyses and electrical conductivity, IR, UV/visible and 1H-n.m.r. spectra. The crystal structure of the complex has been determined by the single-crystal X-ray diffraction. I…
A polyoxometalate-based complex [Cu I (phen)2]4[HPW11.5 VI Cu0.5 II O40] (1) (phen = 1,10-phenathroline) has been synthesized by hydrothermal method and characterized by IR, elemental analysis, TG technique and X-ray crystallography. [Cu I (phen)2]+ ion balances the charge on the α-Keggin [HPW11.5 VI Cu0.5 II O40]4 −…
Fe-Mn alloys have been widely applied to industrial facilities because of their good mechanical properties,high damping capacity at great strain amplitude and low cost.However,the damping mechanism of Fe-Mn alloys is not fully clear now.In this paper,the high damping mechanism of a Fe-Mn alloy and its effect of pre-de…
Abstract The corrosion behavior of Mg‐10Gd‐2Y‐0.4Zr (GW102K) alloy under thin electrolyte layer (TEL) with various thicknesses was investigated by means of cathodic polarization curve, electrochemical impedance spectroscopy (EIS), and electrochemical noise (EN). Based on shot noise theory and stochastic theory, the EN…
This paper describes the application of organic photonic devices including organic light-emitting diodes (OLEDs) and organic photodetectors (OPDs) to integrated photonic devices for the realization of an all-polymeric local-area network. OLEDs and OPDs fabricated by vacuum and solution processes are also discussed. Si…
Abstract This first‐principles study deals with the effect of clustering of different functional molecules adsorbed on the surface of the single‐walled carbon nanotubes (SWCNTs) (5, 5). Here we report the results of our investigation on the effect of clustering on storage capacity, the nature of H2 bonding and strengt…
The vortex phase diagrams of NdFeAsO0.85F0.15 and NdFeAsO0.85 superconductors are determined from the analysis of resistivity and current-voltage (I-V) measurements in magnetic fields up to 9 T. A clear vortex glass to liquid transition is identified only in the oxygen deficient NdFeAsO0.85, in which I-V curves can be…
