Traditional overhead wires are easy to be affected by natural environment.Cable is susceptible to the aging of dielectric and as the manufacturing process constraints,cable's maximum operating voltage and transmission capacity both have reached technical limits.We put forward a new upgrade transmission way of compress…
By theoretical analysis and experimental simulation，planar left-handed metamaterials using double split-ring resonator pairs are studied in this paper. Simultaneous negative permittivity and permeability are described and explained by using equivalent circuit theory. Moreover，double split-ring resonator pairs used in…
Summary: When concrete impact and penetration simulations are discussed, the question of increased strength due to high strain rates arises. Many concrete material modelers cite and use the seminal work of Bischoff and Perry (1991), or the widely accepted standard reference for concrete Comite EuroInternational du Bet…
Hydrogen and nuclear energies are expected as excellent energy resources and are environmentally friendly owing to the absence of emission of carbon dioxide. Toshiba has been developing the high-temperature steam electrolysis technology using solid-oxide cells for hydrogen production by nuclear energy. This paper show…
The oldest MT technique (MVP) has been given new life with the fifth-generation of multifunctional equipment and precision tripods for magnetic sensor installation. The relatively recent many-3H technique brings new advantages to electroprospecting work i
Polymer-derived ceramics (PDCs) are a new class of high-temperature materials synthesized by thermal decomposition of polymeric precursors. These materials possess many unique features as compared with conventional ceramics synthesized by powder metallurgy based processing. For example, PDCs are neither amorphous nor…
Barrier properties against ultraviolet radiation and the light stability of polypropylene (PP) fibres are very important for light-weight summer fabrics as well as for leisure and sport wear. What is more, the thermal stability of PP composites is required in the spinning process and in the thermal treatment of fibres…
Aircraft impact is considered as a relevant loading case in designing modern nuclear power plants. Numerical methods and models need to be verified against experimental data in order to guarantee the reliability of results when simulating full scale applications. The IMPACT test facility has been developed starting in…
Abstract: The marine algal flora of the Arabian (Persian) Gulf received little attention than other marine water bodies. In this paper a total of 26 species are reported for the first time as occurring in the Arabian Gulf coast of Saudi Arabia, including 13 species as new records for the Gulf. These species related to…
Though glass is a remarkably stable material, able to withstand most environmental stresses indefinitely without bulk failure, its surface is relatively easy to damage through mechanical contact with hard materials (e.g. glass or hardened metal) or through chemical exposure to corrosive chemicals (such as alkali solut…
Power devices and systems operating in partial vacuum are susceptible to partial discharges, corona, or volume discharges. In this paper, we present an image-analysis technique and its results for optical-emission characterization of a breakdown initiation. The example set for demonstration is breakdown events under a…
Ferrites nanoparticles have been the emerging focus of the recent scientific research because of the importance of nanotechnology in the present era. They have various possible new technological applications in areas like catalysts, ferrofluids, magneto caloric refrigeration and medical diagnostics. Properties of nano…
Solid solutions of Zn1−xCdxO and Zn1−xMgxO (0≤x≤1) with wurtzite structures are systematically investigated by first principles calculations with special interests on the dependence of energetics and electronic structures on the alloy structure. Alloying ZnO with CdO shows a linear increase in the lattice parameters w…
In this paper the usability of cast iron spheroidizing process in mould control by ATD method as well as by ultrasonic method were presented. Structure of instrumentation needed for control form performance of cast iron spheroidizing by Inmold method was illustrated. Author, pointed out that amount of magnesium master…
Comparison between epoxidised natural rubber (ENR) and natural rubber (NR) filled with organoclay in terms of curing characteristics, tensile properties, thermal stability and morphology were studied. Organoclay loadings from 2 to 10 phr loading were used in this study. The nanocomposites were compounded using laborat…
In this work, a portable solar thermoelectric refrigerator was built in order to help Bedouin people living in remote parts of Oman. The purpose of the study was to demonstrate the feasibility of the implementation of the fabricated solar thermoelectric refrigerator. To this end, a survey questionnaire was conducted i…
Oxidation of [Ru(NH(2)Q)(3)](2+) (NH(2)Q = 8-aminoquinoline) results in intermolecular coupling of 8-aminoquinoline ligands to yield an electroactive polymer. Oxidative polymerization is not observed for [Ru(bpy)(2)(NH(2)Q)](2+) (bpy = 2,2'-bipyridine), where only one 8-aminoquinoline ligand is present.
ZnTMP-PD was synthesized and fully characterized; by using electrochemical and spectroelectrochemical methods, ligand shuttling between the zinc porphyrin and the meso-phenylenediamine substituent could be monitored; EPR results indicated that the charge was delocalized on ZnTMP-PD.
A new carbonate borate, Sr(Na0.4Sr0.1)Na2[B5O8(OH)2] · (CO3)1 − x , space group B2/b, is synthesized under hydrothermal conditions. A new layered anionic boron-oxygen radical based on the 5[3T + 2Δ] block, which is a component of the framework of the subgroup of triclinic hilgardites, is found in the structure. The st…
The compatibility of bismuth compounds as a sintering aid for (ZrO2)0.89(ScO1.5)0.1(CeO2)0.01 (ScSZ) electrolyte in intermediate-temperature solid oxide fuel cells (IT-SOFCs) has been discussed. Addition of 3 mol% BiO1.5 considerably decreased the sintering temperature of ScSZ of approximately 200°C and achieved the d…
