ABSTRACT- An effective way of assessing corrosion in pipelines before serious consequences occur is to use tools that can predict the future of a pipeline through an understanding of its present state and the mechanisms of corrosion. In this work electrochemical methods such as liner and tafel polarization resistance…
Preface Corrupt Peer Reviews by Lev Zlatkevich Properties of Polymers Modified by Plasma Discharge and Ion Beam Research and Review Studies Degradation of Poly (lactide)-Based Biodegradable Materials A Study on Permeation Behavior in Degradable Polymer-PA66 in Acid Solution Application of Mixture Models to the Study o…
The adsorption of carbon on Ni (111) surface is studied with density functional theory in this paper. The adsorption energy and density of states is calculated. We analyzed the density of states of carbon on diamond (111) surface and carbon adsorbed on Ni(111) surface, the result shows that they have similar electroni…
Diatoms are good environmental indicators and are often the main component of phytobenthos, one of the key groups of organisms recommended by the Water Framework Directive (W.F.D.) for the assessment of ecological status of surface waters. Although diatoms are regularly used as indicators in rivers and in lakes, less…
根据新在 nanopatterned 接口上滑动效果，提高水注射进恐水病的 nanomaterial SiO_2 的机制被建议。当 HydrophobicNanoparticles (HNP ) 在多孔的墙的表面上被吸附，恐水病的 nanoparticles 层被形成而不是含水的层，并且滑倒时，当一个开车压力被用于岩石核心样品时，效果出现在毛孔墙上。更快速移动做液体，流动能力极大地增加。改变多孔的墙的 wettability 的实验被进行，并且多孔的墙表面被 nanoparticles 吸附的现象与环境扫描电子显微镜学(ESEM ) 被验证。流动抵抗极大地被减少的排水量实验表演的结果，和水阶段有效渗透被 47 % 在被 nanof…
We present results on n-type silicon cell process development based on large area and thin wafers with screen printed Aluminum-alloyed rear junction concept.An independently confirmed record-high efficiency of 17.4% (140 cm²) has been achieved on floatzone silicon wafers using simple and low cost fabrication technique…
Abstract: The aim of this paper is to compare the machinability of gray cast iron and compacted\ngraphite iron (CGI), in terms of tool life and microstructure. Two gray cast irons with different\ngraphite morphologies and one CGI were tested. After the tool life tests with carbide and Cubic\nBoron Nitride (CBN) insert…
Mineralogical studies were carried out on clayey material found near the water dam in Gaborone city, in Botswana, in order to deduce its chemical composition. Samples of the material were subjected to chemical elemental, thermal and cation exchange capacity analyses. Traces of Kaolinite were found together with quartz…
With the extensive applications of radioactive materials, it is necessary to look for locally available and cheep materials to be efficient absorbers appropriate for shielding from radiation hazards. The attenuation and scattering coefficients of gamma-rays of different energies in thirty samples from two igneous rock…
Corona is one of important problems in the design and operation of transmission lines. It was obtained through experiment and simulation that positive DC corona inception voltage and corona ion current under different air pressure and humidity conditions. Calculated results are in good agreement with experimental ones…
The constitutive models for plastic flow of metal materials under dynamic loading,such as explosive or impact loading,is very important in the impact dynamics,and its studies in recent decades have greatly promoted the development of shock physics,impact dynamics and material sciences,among others.In this paper,some i…
The distributions of the color and luminescence of diamond are reviewed in relation to its growth mechanism. A wide variety of color and luminescence have been reported, which are caused by point defects such as impurities. The color and luminescence are not uniform inside a crystal; they vary depending on growth sect…
X-ray diffraction (XRD) can provide useful information about the composition of an ore sample in terms of quantification of crystalline phases and also amorphous content. XRD is also a powerful technique for studying substitutional solid solutions that can affect mining productivity, such as determining lattice bound…
Abstract: A waste LiCl salt generated from an electrolytic reduction process of a spent oxide fuel could be in-corporated with zeolite A and a glass frit to form a glass-bonded zeolite waste form through blending of the waste LiCl salt with zeolite A, mixing it with the glass frit, and finally thermal treatment at 118…
Rigid open-celled polyurethane foam is the main type of core material in vacuum insulation panels (VIPs). The formulation and manufacturing process of the foam are experimentally analyzed, and the factors that affect cell structure and heat insulation performance are discussed. Vacuum level in VIPs is one of the most…
We have demonstrated that rod-coil molecules based on a tetra-p-phenylene rod and a poly(propylene oxide) coil self-assemble into an unprecedented body centered cubic micellar structure in the melt, through detailed morphological analysis by X-ray scattering and transmission electron microscopy experiments.
In this paper, we report on the performance of microwave phase shifters implemented on sol-gel derived Ba0.3Sr0.7TiO3(BST) thin films. Coplanar waveguide (CPW) phase shifters, loaded-line phase shifters, and reflection-type digital phase shifters have been realized on a single alumina substrate covered with a 300nm-th…
Alkali solution- and heat-treatments were employed to modify the surfaces of Ti-6Al-4V, Ti-40Nb-1Hf and Ti-30Nb-1Fe-1Hf alloys, and then the surface characteristics and the biocompatibility of the treated alloys were analyzed. The formation of porous surfaces that contain numerous nano-pores and irregular cracks, toge…

HgTe nanocrystal-based thin-film transistors (TFTs) with Al2O3top-gate dielectrics were fabricated on glass substrates using sintered HgTe nanocrystals as the channel layers. To the best of our knowledge, this is the first report on the fabrication of nanocrystal-based TFTs on glass substrates. Colloidal HgTe nanocrys…
