Abstract : The objective of the paper was to study the mechanical properties like Ultimate Tensile Strength and Young's modulus are found for the developed composites of different weight % of Graphite and SiC in Al alloy. The composites were prepared by pressure die casting technique and the specimens were subjected…
We report the first to our knowledge high energy graphene mode-locked solid-state laser working in the positive dispersion regime. Pulses with 8.8 nJ energy and 90 nm spectral bandwidth were obtained at 2.4 μm wavelength.
Co(II) , Ni(II) and Cu(II) complexes formed from the Sciff base [ (2Z,4Z)-4- [(2-aminophenyl)imino-]pent-2-en-2-ol] , were prepared in situ and characterized on the basis of elemental analyses, magnetism, UV-vis., IR and ESR spectra . Thermal analyses of the complexes were studied in order to confirm the proposed stru…
It is commonly considered that the corrosion of steel in concrete is controlled by the oxygen content of the pore solution and there are service life models that relate the corrosion rate to the amount of oxygen. It is also commonly believed that in water saturated conditions the oxygen content in the pores is negligi…
In order to produce A2017 alloy strip, a novel semisolid rolling process was studied. The effects of process parameters on microstructure were investigated. The experimental results show that the grain size and roundness of A2017 alloy strip increase with the increment of casting temperature. The grain size of strip d…
A new study for a boron neutron capture therapy irradiation facility, based on a 2.5 MeV proton accelerator on a thick Li target as neutron converter, is presented here.The beam shaping assembly (BSA) modeling has been performed with the use of the MCNP5 Monte Carlo code.The fast (i.e., > 10 keV) neutron component yie…
Abstract In this paper, we first study the voltage and electric field distribution characteristics under the basic lightning impulse level (BIL) of 2400 kV by finite element method (FEM) calculation which are affected by the internal shielding structure of the gas‐insulated bushing for the 1100‐kV gas‐insulated substa…

PURPOSE: To speed up the osteointegration process, surface-treated titanium has been widely used in dental and orthopedic applications. The present work describes a new silicon-based anodic spark deposition (ASD) treatment and investigates the properties of the surfaces obtained, focusing on their capability to modula…
Jet electroforming technology was used to make copper casting layer. The effects of current density, electrolyte jet speed and nozzle scanning speed on the surface morphology of copper casting layer have been investigated. Results show that higher current density, scanning speed and lower jet speed produced a compact…
The innovative design of the next international Material Testing Reactor, the Jules Horowitz Reactor (JHR), induced the development of a new neutron and photon calculation formular HORUS3D/P&N, based on deterministic and stochastic codes and the European nuclear data library JEFF3.1.1. A new integral experiment, named…
Although everybody should know that measurements are never performed directly on materials but on devices, this is not generally true. Devices are physical systems able to exchange energy and thus subject to the laws of physics, which determine the information they provide. Hence, we should not overlook device effects…
This paper focuses on addition of fillers in epoxy resin and aggregate for polymer concrete (PC)preparation. For the preparation of PC, two kinds of fillers, i.e. rice husk ash and broom stem ash were used.According to experimental results, addition of fillers had a positive impact on the physical and mechanicalproper…
The effect of Co addition on the atomic ordering of bcc FeCo-phase in partially nanocrystalline Fe81-xCoxNb7B12 alloys (x= 20.25, 27, 40.5, 54, 60.75) was investigated. In the partially nanocrystalline state of the alloy, the anomalous diffraction measurements provides unambiguous evidence of atomically ordered α′-FeC…
We have studied the wetting of thin liquid (perfluoromethylcyclohexane) films on surfaces nano-patterned with hexagonally packed arrays of cylindrical nano-cavities by X-ray scattering methods. The liquid adsorption on the substrate was controlled precisely by varying the chemical potential of the liquid with respect…
This paper investigates low temperature in situ steam generation (ISSG) oxidation, the correlation between the thickness growth rate and temperature, pressure, hydrogen flow and oxidation time. For low temperature ISSG oxidation, the within wafer uniformity is improved by increasing the temperature. An optimum pressur…
This paper describes a study of the magnetic behavior of ultrathin Co/Pd multilayers deposited on Ru/Ta buffer layers deposited on untreated Si wafers. The ultrathin Co/Pd multilayer requires atomically smooth surface/interface in order to exhibit ferromagnetic behavior as well as perpendicular magnetic anisotropy. Ou…
All structures are likely to be subjected to elevated temperatures during an event of fire. Due to accidental thermal loads the structures may be subjected to cracking and that affect both the mechanical or structural properties. Even though total collapse of structure is rare, the structures or a part of it may suffe…
Calculating conductor temperature of HV cable accurately has been concerned by cable design, operation and management, and power scheduling. In order to calculate conductor temperature accurately based on surface temperature and aluminum sheath temperature, thermal circuit was put forward. We designed temperature risi…
본 연구에서는 벌지 실험을 이용하여 티타늄 박막의 기계적 물성을 측정하였다. 벌지 실험은 외적 지지구조를 가지지 않는 박막 시편의 한 면에 일정한 압력을 가하여 박막의 변위를 측정, 압력과 변위의 관계를 이용하여 박막의 기계적 물성을 측정하는 실험이다. 스퍼터링을 이용해 증착된 티타늄 박막의 두께는 1.0, 1.5, 2.0 ㎛ 이고, 물성의 열처리 시간에 대한 영향을 알아보기 위해 증착된 시편은 600 ℃에서 각각 150, 300, 600 초 동안 열처리 되었다. 박막의 탄성 계수, 잔류 응력, 항복 응력이 벌지 실험을 통해 측정되었고, 실험 결과 항복 응력은 열처…
