One of the crucial problems of the nuclear reactor core is to predict the distribution of neutron flux. Neutron diffusion equation is widely used as an approximation to solve the neutron transport problem. In this study, neutron flux distribution with variation of spatial mesh in the finite slab geometry using one-dim…
Shear stress fluctuation measurements using an electrochemical method in pipe flow
The comparative study of electrocatalysts synthesized by chemical reduction and pulsed magnetron-ion sputtering for polymer electrolyte membrane electrochemical systems are presented. Various carbon nanomaterials were used as supports of Pt nanoparticles: carbon black, nanotubes, nanofibers and reduced graphene oxide.…
TIGER is a 2D/1D coupling 3D transport code developed by Nuclear Power Institute of China based on large-scale parallel computation. It employs 2D domain-decomposed parallel Matrix MOC in the radial direction and 1D finite difference diffusion in the axial direction. 2D domain-decomposed parallel Matrix MOC is acceler…
Polymer colloids have been utilized in the cosmetics and personal care industrial sector for the last several decades. They exhibit unique rheological, tribological, optical, and film-forming properties that make them highly appealing for incorporation into cosmetic products. Of these properties, film formation plays…
, showing high adsorption capacity in removing an ethyl thionocarbamate (ETC) flotation collector. After the deposition with Pt nanoparticles, the photocatalytic activity of the TNFs increased by 94.98% with the enhanced mineralization of the ETC collector. Moreover, the Pt/TNFs on Ti sheets exhibited strong substrate…
Abstract: 5052 aluminium alloy and H62 brass dissimilar metals are friction stir lap welded. The rotation speed is kept constant at 1 000 r/min with welding speed varying from 100 mm/min to 300 mm/min. Microstructure and mechanical properties of the joint are studied. The joint at Al side is divided into weld nugget z…
Rigid-body protein-protein docking is very efficient in generating tens of thousands of docked complex models (decoys) in a very short time without considering structure change upon binding, but typical docking scoring functions are not necessarily sufficiently accurate to narrow these decoys down to a small number of…
The effect of micro-scale structural low-level porosity on strength of structural materials was studied using the three-dimensional Unit Cell Numerical Model - UCNM. A comparison between proposed UCNM and available experimental data in literature was done by comparing obtained values for stress concentration factor -…
A thermodynamic analysis of oxidation of copper nanoparticles was performed. The first step of oxidation, namely Cu2O formation on the surface of spherical copper particles (core-shell model) was considered. Our results show a spontaneous oxidation of particles at oxygen pressures well below the equilibrium oxygen pre…
In this paper authors overviewed the most important stages of ceramics production process which give significant influence on final properties of product. Often density and porosity on the all producing stages determines exploitation ceramics properties. A calculation method for fractions ratio selection which provide…
Fe 2 O 3 nanorods, multi-walled carbon nanotubes (MWCNTs) and reduced graphene nanosheets (rGO) have been assembled to form Fe 2 O 3 -MWCNTs/rGO hybrid nanostructures for high sensitivity detection of hydrazine. Hydrolysis reaction and annealing were firstly used to grow Fe 2 O 3 nanorods on MWCNTs, resulting in high…
The preparation of Metal Matrix Composite (MMCs) Al/SiCp and Al-Cu/SiCp with the addition of silicon carbide powder (SiCp) and mixing with the hot sterring method has been done successfully. Material Al and Al-Cu melted in the temperature of 900°C then added SiC with variations (1, 2, 3, 4) weight % with the method of…
A new and convenient method for individual identification of Fe 3+ ions by the combination of Cd-P and Tb 3+ @Cd-P was successfully established.
The exploration of nano fillers such as multi walled carbon nano tubes (MWCNTs) and graphene powders (GNPs) in the glass fibre reinforced polymers was found to augment the mechanical properties of the fibre reinforced polymers of the entire range after applying impact. The main imperative criterion is MWCNTs and graph…
In order to improve the defect of incompleteness, three-dimensional I-shaped fabrics with basalt fiber filaments tows were woven on the semi-automatic loom by reasonable design. Three-dimensional I-shaped woven composites were prepared by the vacuum-assisted resin transfer molding process. The compressive behaviors of…
The use of substituting cementitious materials (SCMs) to produce low-carbon concrete is escalating. This contributes to reducing the anthropogenic emission of CO2, and to reduce harmful temperature gradients during cement hydration in massive structures. Mature low-carbon concretes are known to perform well on both st…
and generate a planar carbanion intermediate, which is then putatively reprotonated on the opposite face by a water molecule to form (3S)-β-MeInPy in a stereospecific manner. The details of β-site isomerization at the atomic level provide deeper insights into the epimerization mechanism of MarH and will facilitate fur…
Abstract Waste tires are processed to modify asphalt binders. Asphalt pavement constructed using crumb rubber modified (CRM) binders have shown good rutting and fatigue performance. However, the use of CRM involves high construction temperature. High temperature leads to aging and successive degradation of CRM binders…
