First, the dissolution of water into different types of oxides is discussed, including the influence of the water pressure and the oxygen activity. Then the transport of water, i.e. of hydrogen–containing species, in such oxides and its dependence on the water pressure and the oxygen activity is analyzed. Hydrogen–con…
Abstract The effect of sunlight and drying methods on the strength of Real Wax printed cotton fabrics produced in Ghana was determined. Warp and weft specimens were washed using the Standard Launder‐Ometer (Gyrowash 315). Each laundered or unlaundered specimen was aired or dried on a flat surface or on clothesline in…
In a CANDU (CANada Deuterium Uranium) reactor, fuel channel integrity depends on the coolability of the moderator as an ultimate heat sink under transient conditions such as a loss of coolant accident (LOCA) with coincident loss of emergency core cooling (LOECC), as well as normal operating conditions. This study pres…
The influence of permanent-magnet-driven stirring during solidification on the microstructure and corrosion property of AZ61 magnesium alloy was investigated. The corrosion behaviour of AZ61 was studied in 3.5mol/L NaCl by measuring electrochemical polarization. The results show that the permanent-magnet stirring refi…
The as-grown PrAlO3 single crystals grown by the Czochralski method are brown colored and after annealing in the reducing atmosphere (20%) H2/N2 they change the color to green. The X-ray photoelectron spectroscopy was used to study the chemical composition and electronic structure of PrAlO3 single crystals before and…
(graphite/PVC) segregated composites with different concentrations of graphite and their application to the shield effectiveness of electromagnetic radiation in the X-band frequency range 8–12 GHz. The incorporation of graphite is related to the formation of conducting channels. It is found that conducting channels ar…
JFE Steel Group developed a new fine iron oxide powder JC-FH04. Fine magnetic powders, which are obtained by applying a wet synthesis method, are oxidized by heating to produce high purity fine iron oxides with specificsurface areas above 1.2 X 10 4 m 2 /kg. It is confirmed that the sintering temperature of NiCuZn fer…
Using grand canonical ensemble Monte Carlo method,the effect of micropores,mainly the hollow cores of single-walled carbon nanotubes(SWNTs) and the interstitial channel among SWNTs,on the hydrogen adsorption of SWNTs was studied.Comparing with experimental observations,it was found that the hollow cores of SWNTs are t…
The modified myrica rubra extract suitable for tanning heavy leather at low temperature tanning was prepared by sulfitation with compound containing nitrogen added. It was found thatthe modified myrica rubra extract's viscosity was significantly decreased and its astringency was gentle. Quantitative analysis and tanni…
The in situ intercalated polymerization of vinyl acetate (VAc)-montmorillonite (MMT) was initiated via γ-ray irradiation in a 6 kCi ~(60)Co irradiator and got the MMT-PVAc nanocomposites, as well as we got the PVAc. Blends of PVAc/PA6/HDPE (PHA) and MMT-PVAc/PA6/HDPE (PMHA) were prepared in a Rheomixer XSS-300 as 50 g…
High-speed dry face-milling tests were conducted for difficult-to-cut ultra high strength alloy with σ_b1.4 GPa and hardness 50HRC and martenstic stainless steel with hardness 30HRC, using (Ti,Al)N coated carbide tool and fine grain carbide tool, respectively, on a DMU-70 evolution 5-axle processing center. The morpho…
Equiatomic NiTi shape memory alloy was being increasingly utilized as a biomaterial due to its unique biomechanical compatibility,corrosion resistance and biocompatibility. The present review attempts to summarize the complex properties of NiTi,and to assess corrosion resistance and biocompatibility of NiTi as a bioma…
Clay minerals are widely applied in reconstructing paleoclimate, and many analysis methods are involved.Among them the X-ray diffraction analysis(XRD) is mainly used to confirm clay mineral assemblages and their crystallinity; chemical analysis and electronic microscope are used to study the source, the genesis and th…
Three volatile corrosion inhibitors (VCIs) namely, benzoic hydrazide benzoate (BHB), benzoic hydrazide salicylate (BHS), and benzoic hydrazide nitrobenzoate (BHN), were synthesized and evaluated as corrosion inhibitors of mild steel, brass and copper by weight loss method. Eschke test method, sodium chloride inoculati…
This book arises out of a course I am teaching for a three-credit (42 hour) graduate-level course Dosimetry Fundamentals being taught at the Department of Nuclear Engineering and Radiological Sciences at the University of Michigan. It is far from complete. A formal course in dosimetry usually starts at Chapter 4, Macr…
This paper presents the modelling of a Polyvinyl Chloride (PVC) resins manufacturing process with batch process simulator, SuperPro Designer V6.0. The simulation model has been developed based on the operating condition of a local PVC manufacturing plant. As the polymerisation process is carried out in batch operation…
High voltage rotating machines remain to play a significant role in generating electrical energy. One of the main causes for down times of these machines is related to problems in the winding insulation. The deregulated energy market leads to cost pressure on the producers of the insulations and the utilities. While m…
Abstract: Partial discharge monitoring is an effective on-line predictive maintenance test for motors and generators, as well as other electrical distribution equipment. The benefits of on-line testing allow for equipment analysis and diagnostics during normal production. Corrective actions can be planned and implemen…
Diamond layers have a potential application as the highest band-gap semiconductor for electronic devices. One of the major problems is to form electric contact on the diamond surface useful for an electronic device. This paper shows the properties of the contacts formed by the very promising ion implantation technique…
Thin films of SrAl 2 O 4 :Eu,Dy were successfully deposited on polyethylene substrates at room temperature by pulsed ion-beam evaporation. From X-ray diffraction analysis results, the thin films were found to consist of a crystallized SrAl 2 O 4 :Eu,Dy phase. In the measurements of the photoluminescence properties of…
