Pulsed composite electrodeposition and interdiffusion treatment were used to develop a Ni-Al protective coating on low carbon steel. The morphology and microstructure of the coating were investigated with SEM and XRD. The coating is composed of a continuous Ni-rich phase and discrete Al-rich particles enclosed in the…
The silane 3-methacryloxypropyltrimethoxysilane is one of the oldest and still one of the most important coupling agents available for improving the practical adhesion of polymers to minerals. It has also featured strongly in research and development studies establishing the dominance of the chemical bonding theory as…
The advantages of moving from 2-Dimensional Networks-on-Chip (NoCs) to 3-Dimensional NoCs for any application must be justified by the improvements in performance, power, latency and the overall system costs, especially the cost of Through-Silicon-Via (TSV). The trade-off between the number of TSVs and the 3D NoCs sys…
Avrami equation was applied to model the formation process of fly ash based Linde F (K) zeolite. The results showed that: (1) Linde F (K) zeolite could be gained through the reaction between fly ash and potassium hydroxide solutions and temperature seriously affected the reaction rate. (2) Avrami equation could be suc…
Effects of plasma exposure for tritium retention have been studied using both samples of a plasma-exposed stainless steel and a bare stainless steel. It was seen that the plasma-exposed surface was covered with thin deposition layers. Constituent elements of the deposition layers mainly formed metallic oxides except f…
The combination of ultrasonic irradiation and Fenton-like's reagent is effective for the degradation of Acid brown 348 in aqueous solution. Furthermore, it can achieve better results than either Fenton-like reagent or ultrasound alone. Effects of the reaction conditions on the removal of Acid brown 348 from aqueous so…
Bis(thiourea) cadmium acetate, a metal semiorganic non-linear optical crystal, was synthesized from thiourea and cadmium acetate using double distilled water. The synthesized salt was used to grow bulk size crystals. The XRD analysis confirmed that bis(thiourea)cadmium acetate has orthorhombic crystal structure. The U…
The crimp of the text ile fibers is very crit ical to determine its properties and volumin isity. The microscopic characteristic of the nonwoven fabric is totally depends on the linearity and length of the crimp and the amp litude of the crimp. In this review paper we have discussed about the crimp calculat ion, measu…
MgO-templated mesoporous carbons with different heat treatments are examined as both negative and positive electrodes in lithium-ion capacitors. MgO-templated carbon heated at 2200 °C has a specific surface area of 800 m2/g and a total pore volume of 1.2 cm3/g, and shows superior performance as a negative electrode of…
This work focused on the relation between the porous structure of activated carbon and its capacitive properties. Three types of activated carbon monoliths were used as the electrodes in a half cell electrochemical system. One monolith was produced from activated carbon and considered to be a binder-less electrode. Tw…
Classical techniques for register allocation and binding require the definition of the program execution order, since a partial ordering relation between operations must be induced to perform liveness analysis through data-flow equations. In High Level Synthesis (HLS) flows this is commonly obtained through the schedu…
In this paper, we formulate and experimentally demonstrate direction of arrival (DoA) estimation with a two-port composite right/left handed (CRLH) leaky-wave antenna (LWA) using the multiple signal classification (MUSIC) algorithm. The CRLH LWA consists of a cascade of metamaterial unit cells, peri
High concentrations of rubidium and cesium have been found in the salt lake brines of western China. These rare alkali metal ions coexist with sodium, potassium, magnesium and sulfate in salt lake brines. Phase equilibrium researches on the salt lake systems will provide the theoretical basis for the extraction of rub…
to develop a corrosion inhibition process to prolong the life of existing structures and minimize corrosion damages 1 . At industrial coastal areas, penetration of the acidic media on steel bars, through chemical or mechanical cracks of concrete, caused corrosion of them 2-6 . Use of inhibitors is one of the most prac…
Analytical solutions are derived for the macroscopic behaviors of a Shape Memory Alloy (SMA) thick-walled cylinder subjected to internal pressure and radial temperature gradient. The Tresca transformation criterion and linear hardening are used. Equations are given for the radial and circumferential stresses, transfor…
Ni-TiO2 nanocomposites coatings with a layer thickness of 21 μm have been obtained by electrocodeposition. Incorporation in nickel matrix of TiO2 nanoparticles (10 nm), affects the morphology of the nickel matrix as indicated from scanning electron microscope (SEM) and atomic force microscope (AFM) results. The chemic…
For the group 5 metals, even in an ambient hydrogen atmosphere (pressure), a large amount of hydrogen dissolves into them and severe hydrogen embrittlement occurs. This means that there is a large barrier to the practical application of these metals as a hydrogen permeation membrane for hydrogen separation and purific…
The carbonization characteristics such as char properties and gas release rate of biomass/coal blend have been determined in a batch-type carbonization reactor. The yellow poplar as a biomass is added to a coal with different levels (10, 15, 20, 30 wt%) at various final temperature (500 – 800°C). The carbonization cha…
The accelerated wet-dry cyclic corrosion tests have been carried out of a high strength bainitic steel and 09CuPCrNi. The results indicated that the corrosion resistance of 09CuPCrNi was better than that of the bainitic steel based on the mass loss measurements. The morphology and composition of the rusting products h…
A phase-field model with forced liquid metal flow was employed to study the effect of boundary heat flux on the dendritic structure forming of a Ni-40.8%Cu alloy with liquid flow during solidification. The effect of the flow field coupling with boundary heat extractions on the morphology change and distributions of co…
