Abstract:

The electronic and crystal structures of oxide-nickel compositions based on ternary barium-calcium-strontium carbonates containing nickel nanoparticles and nanocrystals of barium carbonate have been studied by electron spectroscopy and precision X-ray structural analysis. It was found that nickel nanoparticles have a significant effect on the parameters of the electronic structure of barium oxide crystallites formed in these compositions during their heat treatment. It is shown that X-ray diffraction analysis can be used as the basis for the method of quality control of ternary carbonates for

AbstractThe structural properties of one- and two-layer heterostructures based on the barium–strontium titanate of various compositions deposited by the Frank–Van der Merve on a magnesium oxide substrate have been studied.

The principal difference of this method of deposition from known analogs is that the growth of single-crystal films occurs from a disperse oxide phase formed in the plasma of a high-current rf discharge during the ceramic target sputtering a

Abstract:

In this experiment, the oxide nanoparticles were synthesized via chemical precipitation and the nanocomposites were produced using in situ polymerization method with varying nanoparticles contents ranged from 0 to 5 g. The mechanical properties of the nanocomposites were investigated and compared with the values obtained for untreated polystyrene. It was observed that the mechanical properties were higher for the nanocomposites and increase with increasing nanoparticle concentrations in the samples. It can be observed that the untreated polystyrene gave a tensile strength of 945.25 N/mm2. At h

Abstract:

The synthesis patterns of powders in the calcium–phosphate–alkali silicate system, intended for use in glass ionomer cement formulations, were investigated using sol-gel technology. To enhance the performance characteristics of the resulting composites, the feasibility of modifying the base powder composition with barium and lithium oxides was confirmed. A comparative analysis was carried out to evaluate the influence of the liquid phase – comprising mixtures of organic carboxylic acids (acrylic, tartaric, maleic, and itaconic acids) – on the formation of structure and properties of the compos

Abstract:

The electrochemical oxidative coupling of methane (E-OCM) to higher hydrocarbons, requires anodes that are stable under reducing conditions. We have previously demonstrated high activity with long term stability/durability for the perovskite anode BaMg0.33Nb0.67-xFexO3-δ (BMNF) while performing E-OCM1. Our group has also improved the total conductivity and activity of barium niobate perovskites via exchange of Mg for Ca (from 18 mS/cm-1 to 41 mS/cm-1), while also decreasing the Goldschmidt tolerance factor below 1 for increased cubic perovskite structural stability2.

Abstract:

Health care workers performing radiography on patients in hospitals typically wear aprons for radiation protection. Protective properties are achieved through a combination of shielding materials and polymers. Various shielding materials are mixed with polymers to prepare composite materials. Numerous methods have been devised to design and alter the composition of these materials to improve the shielding performance of aprons. In this study, the shielding performance was analyzed based on the arrangement of shielding materials, the composition of materials (mixed or single), and the fabricati

Abstract:

The electrochemical reduction of molecular oxygen is a fundamental process in Solid Oxide Fuel Cells and requires high efficiency cathode materials. Two La0.25Ba0.25Sr0.5Co0.8Fe0.2O3−δ-based perovskite compounds were prepared by solution combustion synthesis, and characterized for their structural, microstructural, surface, redox and electrochemical properties as potential cathodes in comparison with Ba0.5Sr0.5Co0.8Fe0.2O3−δ and La0.5Sr0.5Co0.8Fe0.2O3−δ perovskites. Results highlighted that calcination at 900 °C led to a “bi-perovskite heterostructure”, where two different perovskite structure

Abstract:

Superconductivity in potassium-doped BaBiO3 was first observed by Mattheiss et al. in 1988 and the structure of the superconducting material was determined by Cava et al. The material crystallizes in a simple perovskite structure with potassium substituted on the barium site as shown in Figure 1. Unlike the layered copper-oxide materials, this compound is simple cubic and thus isotropic in the superconducting state and shows no magnetism. Band theory calculations show that the electronic structure is simple, with conduction bands composed of Bi(sp)O(p) hybridized orbitals and, unlike the coppe

With the slowing down of Moore’s law, related to conventional scaling of integrated circuits, alternative technologies will require research effort for pushing the limits of new generations of electronic or photonic devices.

ABSTRACTIn this work, we report evidences of the improvement of X-ray attenuation efficiency by the addition of a very small amount of Graphene Oxide (GO) in polymer-based nanocomposite. Poly(vinylidene fluoride) (PVDF) homopolymer and barium sulfate (BaSO4) nanoparticles were mixed. PVDF/BaSO4 nanocomposite was found to attenuate 9.14% of a 20 kV X-ray beam. The addition of only 4.0 wt % of GO nanosheets to the nanocomposite improved this X-Ray attenuation efficiency to 24.56%. The respective linear attenuation coefficients (μ) were 39.9 cm-1 and 54.4 cm-1, respectively. The X-ray attenuation

This paper examines the effect of helium ion implantation on the properties of proton conductors based on barium cerate (BaCeO₃). The crystal structure, proton conductivity mechanisms, and chemical stability of the materials are investigated. It is shown that doping with rare earth elements increases the concentration of oxygen vacancies, improving conductivity. The effect of ion irradiation is analyzed in terms of changes in the defect structure, the formation of new oxygen vacancies, and their effect on the electrophysical properties of the material.
