An efficient neutron transport-based multiphysics coupling algorithm is developed to model fast-burst reactor dynamics. It extends the previously developed tightly coupled implicit-explicit (IMEX) multiphysics algorithm based on neutron diffusion and linear mechanics to follow the dynamic time scale of the problem. Th…
Rutherford backscattering of energetic particles can be used to determine the thickness of a coating of a low-Z material over a heavier substrate. Simulations indicate that 5 MeV alpha particles from an (241)Am source can be used to measure the thickness of a Li coating on Mo tiles between 0.5 and 15 μm thick. Using a…
Nanocomposites based on poly (vinylidene fluoride) (PVDF) and expanded graphite (EG) were prepared by non-solvent precipitation from solution with different EG concentrations. Films were obtained by compression molding and their structural and dielectric properties studied. From Wide Angle X-ray Scattering (WAXS) expe…
High Temperature properties in nanocomposites have received significant attention in recent years due to its potential as an efficient refractory material. Nanoenabled spinel refractory products are finding widespread application owing to their enhanced temperature withstanding limits coupled with excellent abrasion r…
The flows in the human upper airway and human heart during open heart surgery are considered. Beginning with idealized models of the human upper airway, current methods to extract realistic airway geometries using a novel implementation of optical coherent tomography modality are introduced. Complementary direct numer…
With the rapid development of computer network and information technology, traditional clothing industry has taken a giant stride forward to computer information and digitization. In this paper, 250 3D point-cloud photos of young females were selected as subjects, and related characteristic points of neck rhizosphere…
By adding 5% (w/w) of halloysite nanotubes that have been modified (loaded) with proteins or drugs it is possible to produce strong and functional biocomposites. Materials loaded with both types of materials were investigated using ultraviolet-visible spectrophotometry and thermogravimetric analysis to determine their…
Abstract The carrier dynamics under solar excitation in the third generation AlAs‐Ga0.27In0.73As quantum well solar cell on an InP substrate is theoretically investigated. The quantum well shows a significantly higher carrier occupation compared with that of a pure bulk sample. Furthermore, the influence of carrier sc…
Purpose – Clothing quality, performance, safety and health have become important considerations for consumer welfare. Properties of these aspects are encompassed on standards which regulates clothing products reaching consumers. The purpose of this paper is to categorize these aspects in a common platform by suggestin…
Noble metals as cocatalysts for hydrogen evolution are widely investigated for semiconductor photocatalytic water splitting. In this paper, we present a novel way to attach not only noble metals, but also transitional metals onto CdS nanocrystals as cocatalysts for hydrogen evolution. The hydrogen evolution performanc…
We have studied the effect of modification with Ba on the phase composition, structure, and electrical properties of ceramic samples of Pb(1−x)Bax(Mg1/3Nb2/3) m (Zn1/3Nb2/3) y (Ni1/3Nb2/3) n Ti z O3 (0 ≤ x ≤ 0.15) solid solutions and investigated phase equilibria in this system in the range 0 ≤ x ≤ 0.15. The results i…
In this study, the fabrication of self-assembled Au droplets is successfully demonstrated on various type-A GaAs substrates: (711)A, (511)A, (411)A, and (311)A. The nucleation of the self-assembled tiny Au clusters is observed at 300 °C. As an intermediate stage, corrugated Au nanostructures are clearly observed at 35…
A concept of the turbidimetric method for determining the concentration of ethanol in water–ethanol mixtures is described. A closed sample cell containing the analyte was heated to achieve vapor saturation and subsequent condensation. As the condensation occurred, the decrease in percentage transmittance with time due…
The nonlinear metamaterial is considered as a cut-wire embedded in a nonlinear dielectric and its effective linear and nonlinear properties are simulated using a finite element-based software. First, the linear properties of the considered structure, the effective electric permittivity, and magnetic permeability, are…
Responses of organic fluorophore, perylenediimide derivative N,N′-di[3-[2-(3-thienyl)ethyl]phenyl]perylene-3,4,9,10- bis -(dicarboxyimide) ( PDI1 ) was investigated in polymer matrix of polyvinyl chloride ( PVC ) by emission spectrometry. Its response to Fe(III) ions was evaluated in terms of the effect of pH. The pro…
Various surface modifications have been applied to improve the adhesion properties of aluminum for the cap plate and sealing quality of electrolyte on Li ion batteries. In this study, we have tried to find the effective condition for the polymerization of triazine thiols (TT) on modified aluminum surfaces by anodic al…
Lithium ion mobility and the superionic phase transition in the Li0.12Na0.88Ta0.4Nb0.6O3 solid solution have been studied using temperature-dependent ionic conductivity measurements and Raman spectroscopy. From the temperature dependences of the conductivity and the width of a Raman line corresponding to Li+ and Na+ v…
BACKGROUND: Dysregulation in transforming growth factor (TGF)-β1 signalling pathways has been linked to cancer. AIM: To study the association between single nucleotide polymorphisms (SNPs) of the TGF-β1 gene and mycosis fungoides (MF). METHODS: Using restriction fragment length polymorphism analysis, SNPs in the TGF-β…
Titanium dioxide (TiO2) films were deposited onto polyurethane (PU) and polyvinyl chloride (PVC) leather by magnetron sputtering, respectively. The crystal structure of the prepared film was studied using X-ray diffraction (XRD) and the surface morphology of the TiO2 films was investigated by scanning electron microsc…
