Kaolins are common geological materials and have high concentrations of kaolinite as well as the clay fraction of tropical and subtropical soils of Brazil. The characterization of kaolin is a proxy of assessing the contribution of kaolinite to important soil chemical and mineralogical attributes. This study evaluated…
Abstract This article demonstrates how FEA-based tools are used to model residual stress and distortion in a full-float truck axle induction hardened and cooled at different rates. The effect of cooling rate on axial displacement is discussed.
The Nuclear Regulatory Commission (NRC) has recently completed an updated Spent Fuel Transportation Risk Assessment, NUREG-2125. This assessment considered the response of three certified casks to a range of impact accidents in order to determine whether or not they would lose their ability to contain the spent fuel o…

EGC Critical Components, a US company that manufactures precision polymer components for a variety of industries, has selected Victrex polyetheretherketone (PEEK) for use in a self-actuated abeyance seal system that is being employed in a nuclear power plant.
The aim of this research was to create and investigate a formulation that could be placed within post-extraction alveolus. The main material used in this work is a natural polymer, known as microcrystalline chitosan (MCCh). It was formulated as an aqueous hydrogel with the addition of the cross-linking agent (CaCl2) a…

In this work we have studied the effects of high neutron fluencies and gamma doses on the structural properties of three different types of silica glasses: two high purity silica with different OH content, KU1 (800 ppm) and KS-4V (<;0.2 ppm); and a commercial silica Infrasil 301 (<;8 ppm). The experimental results (Ra…
In this work, a model has been developed to calculate the neutron wall loading poloidal distribution in a generic tokamak plasma and vessel geometry on the basis of Monte Carlo simulation. Different neutron source radial profiles corresponding to advanced plasma scenarios have been implemented in this model, using com…
Hydrogen dissolves in and permeates through most materials, thus it is important to understand the permeation, diffusion and dissolution phenomena of hydrogen and its isotopes in materials. We address the problem of tritium transport in Helium Cooled Lead-Lithium (HCLL) DEMO blanket from lead-lithium breeder through d…
Effect of 2-aminobenzenethiol (ABT) on copper corrosion as a corrosion inhibitor in an aerated acidic solution of 2 M HNO3 has been investigated using gravimetric and electrochemical techniques. A significant decrease in the corrosion rate of copper was observed in the presence of the investigated organic compound. Th…
Abstract : Transport and mechanical properties for a range of knit, woven, and felted fabrics under consideration for extremity protection are reported. The textiles include: knits of silk, polyester, staple aramid, and continuous-filament aramid; plain woven nylon-cotton blend and continuous-filament aramid; and felt…
In the article asymptotic solution of the problem of defining of stressed state of strain and field of continousness in the neighbourhood of crack tip in the sample which is in state of mixed deformation is received. On the basis of self-similar presentation of solution and hypothesis about the formation of area fully…
The study of space debris is of critical importance to all space-faring nations. The characterization of debris objects through means of passive imaging techniques would allow for further studies into the origination, specifications, and future trajectory of debris objects. The long-wave infrared waveband is a potenti…
Abstract : At the nanoscale, the optical, electrical, and catalytic properties of a material depend on its size and shape. Therefore, synthesis of nanoparticles with controlled size and shape is important for their application in biosensors, photonics, and other optoelectronic devices. Whereas the effect of size on th…
Optoelectronic functional molecules are usually used as films or aggregates. The discovery of aggregation induced emission (AIE) molecular systems supplies a novel method to solve the problem of aggregation-induced fluorescence quenching (ACQ). In this paper, we summarized a series of AIE molecules developed in our gr…
In this study, unsaturated polyester resin (UPE) and Natural rubber (NR) were used to prepared binary polymer blend (UPE/ NR) with weight ratio (95/5) %. The present paper investigates the diffusion behavior of three environmental groups , the first group is different types of water included (distilled water, tap wate…
A comparative study of the defect formation and changes in the lifetime of nonequilibrium minority charge carriers in silicon while gettering the iron impurity with the use of a combined getter “porous silicon layer + aluminum film” is carried out. It is shown that, while annealing specimens with no getter layer, iron…
Structural, optical, and electrical properties of InSe and GaSe single crystals diffusely intercalated with ethanol have been studied. The X-ray analysis confirmed that ethanol molecules become introduced into the interlayer space of samples. The dependences of the energy position of the main exciton maximum and a hal…
Films of Poly Methyl Methacrylate (PMMA) doped by (1%) Potassium Iodide (KI) have been prepared using casting method at room temperature. Optical properties were investigated for different thicknesses by using spectrophotometeric measurement of absorption reflection transmission in the wave length range (200-800) nm.…
