The perturbation theory based on the transport calculation has been applied to study sensitivity of neutron multiplication factors (keff's) to neutron cross sections used for the reactivity analysis of UO2 and MOX core physics experiments on light water reactors. The studied cross sections were neutron capture, fissio…
As a solid oxide fuel cell (SOFC) system is under dynamic development for a profitable use in the future, it is very important to understand its transient characteristics. In this paper, the modeling and simulation of an energy integrated SOFC system has been performed to analyze the dynamic characteristics of the hea…
Causticizing calcium carbonate (CCC), known as lime mud, is a byproduct of the papermaking industry that comes from the green liquor causticizing process. In China, CCC has been used as a paper filler to replace precipitated calcium carbonate (PCC). This is beneficial for saving resources and preventing secondary poll…
Phase behaviors of supramolecular graft copolymers with reversible bonding interactions were examined by the random-phase approximation and real-space implemented self-consistent field theory. The studied supramolecular graft copolymers consist of two different types of mutually incompatible yet reactive homopolymers,…

Abstract Aluminium coatings applied using arc or flame spraying processes are frequently employed for protection of steel structures in maritime applications. Results of comparative testing of aluminium coatings produced by manual and robotized flame spraying on steel substrate are reported in the contribution. Partic…
An Ni-4.8at%Ti alloy was prepared and the electron energy loss spectroscopy (EELS) of nickel was collected. The d-electron occupancy of Ni is measured from the white-line intensity of EELS. It was found that relative to pure Ni the d-electron occupancy of Ni in Ni-4.8at%Ti alloy did not change significantly.
Nanocrystalline Ga doped nickel ferrite [(NiFe2-xGaxO4 (x=0.0, 0.1, 0.3, 0.5 and 0.7)] powders have been synthesized by sol-gel auto-ignition method and the effect of non-magnetic gadillum content on the nanosize particles and magnetic properties has been studied. The X-ray diffraction (XRD) revealed that the powders…
Wear by slurry abrasion is very expansive problem that must be taken into consideration while selecting the material for the transportation of slurry through pipeline. Abrasive wear generally occurs when abrasive slurries come in contact with the industrial engineering components or slurry transporting pipes. The abra…
Peristicta guarellae sp. nov. (holotype: Brazil, Paraná State, Exc. 399/col. 3, stream in km 50 of Curitiba-Ponta Grossa route [BR 376], about 25°20′08″ S, 49°51′15″ W, 21 November 1971, N. D. Santos leg., deposited in the Collection of “Museu Nacional, Universidade Federal do Rio de Janeiro”, Rio de Janeiro, Brazil)…
This paper explains the influence of oxygen partial pressure on crystallographic structure, surface morphology and sensing properties of sputtered MoO3 thin films. The MoO3 thin films were deposited by DC reactive magnetron sputtering technique on glass substrate at different oxygen partial pressures in the range of 5…
Nano-structured hydrotalcite based mixed oxides have been synthesized using coprecipitation method under variable pH and low supersaturation condition. XRD technique has been used to confirm the hydrotalcite structure and its derived different phase of mixed oxides. The metal dispersion of mixed oxides was analyzed us…

Nanotori, or nanorings, are topological variants of nanotubes and are conceived to have different properties from their tubular form. In this study, the toroidal arrangement of boron nitride is introduced. Using classical molecular dynamics simulations, the thermal behaviour (thermal conductivity and thermal stability…
Novel molecules have been synthesized that combine the phenolic nature of tannins and self-assembling properties of surfactants. These single-chain (C12) surfactants with potential biocompatibility have been synthesized with an ω-thiol or disulfide functionality, both commonly used anchors in self-assembly onto gold s…
We report an investigation of Coulomb blockade transport through an endohedral N@C60 weakly coupled with aluminum leads, employing the first-principles method combined with the Keldysh non-equilibrium Green's function derived from the equation of motion beyond the Hartree-Fock approximation. The differential conductan…
Due to the growing interest in using mesoporous materials as catalytic support, this paper presents the synthesis and characterization of mesoporous silica (SBA-15) prepared under different synthesis conditions. Variables studied were acidity of the synthesis duration, synthesis sol, aging duration, and washing solven…
