The study of the physical and chemical properties of artifactual glass can contribute greatly to the attribution of artifacts and to the study of their history. In this paper, we study the interplay of physical and chemical properties of glass and classify them. In order to make the classification more accurate, the correlation coefficients of compounds were calculated using Spearman's coefficient, and the content of lead oxide was determined as the basis for the classification. After that, this paper used K-means++ to cluster the data and selected calcium oxide and alumina as the sub-classifi

Furthermore, the glass composition and the simulated X-ray or gamma-ray energy predict the shielding behavior. The optimal thickness for all glass samples to achieve a 90% reduction in intensity at an energy of 59.54 keV is 5.2 mm. These glasses have great potential as materials for shielding against gamma and X-rays.

The homogeneity ranges and crystal structure of solid solutions of Nd1−x1BaxCo1−y1FeyO3−δ3 composition were detected. Depending on introduced barium concentration Nd1−x1BaxCo1−y1FeyO3−δ3 oxides have been crystallized in the orthorhombically distorted (x = 0.05, sp. gr. Pbnm), cubic (0.6 ≤ x ≤ 0.9, sp. gr. Pm-3m) perovskite structure or double perovskite structure NdBaCo2−x2FexO5+δ5 (0.0 ≤ x ≤ 1.4, sp. gr. P4/mmm). The dependencies of unit cell parameters versus composition of the Nd1−x1BaxCo1−y1FeyO3−δ3 solid solutions were obtained. It is shown that the values of oxygen nonstoichiometry in Nd

AbstractThis issue of MRS Bulletin provides an overview of the current status of research and development in the area of high-temperature superconductor (HTS) wires. High-temperature oxide superconductors, discovered in the late 1980s, are moving into the second generation of their development.The first generation relied on bismuth strontium calcium copper oxide, and the second generation is based on yttrium barium copper oxide, which has the potential to be less expensive and to perform better.The potential uses of HTS wires for electric power applications include underground transmission cab

The radiological protection has the purpose of safeguarding the physical well-being of the user, preventing exposure to detrimental levels of ionizing radiation. This study introduces a novel, cost-effective category of lead-free elastomeric material designed for radiation shielding. The filler compounds utilized are notably lighter than conventional lead-based materials, enhancing user ergonomics during application. They comprise of a blend of barium sulfate combined or not with magnesium oxide with addition-cure liquid silicone rubber. To ensure the effectiveness of the radiation shielding,

AbstractPolycrystalline yttrium barium cobaltite (YBaCo4O7) powdered sample was prepared by conventional solid state reaction route using high purity yttrium oxide, barium carbonate and cobalt oxide. The as-prepared sample was characterized by XRD diffraction, SEM/EDAX, Raman analytical techniques, resistivity and magnetization measurements for structural, morphological, electrical and magnetic properties assessment. XRD pattern confirms the single phase formation of the sample without any impurity. SEM image shows the hexagonal growth of the crystal and EDAX spectrum reveals stoichiometric co

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. Perovskite oxides with the ABO3 chemical formula have a very wide range of interesting intrinsic properties such as metal-insulator transition, ferroelectricity, pyroelectricity, piezoelectricity, ferromagnetic and superconductivity. For the integration of such oxides, it is of great interest to combine their properties with traditional electronic, memory and optical devic

A kind of photoemissive thin films, which does not contain alkali elements but contains metallic ultrafine particles, is studied. A typical kind is the thin film of silver ultrafine particles embedded in the barium oxide. There are two methods in the formation of Ag-O-Ba thin films: single-metallic layer method and multimetallic layer method. The photoelectric emission response curve to wavelengths between 350 and 800 nm is given. The energy band with respect to the position diagram in the neighborhood of its surface is also presented.

Among various types of solid oxide electrochemical cells, protonic ceramic fuel cells (PCFCs) have been expected to reduce the operating temperature below 600 °C with their significantly high ionic conductivity and activation energy. For example, recently developed proton conductor (BaZr0.4Ce0.4Y0.1Yb0.1O3-δ, BZCYYb) ideally has ~12-fold higher ionic conductivity (2.810-2 S/cm at 600 °C) and low activation energy (Ea < 0.4 eV) than those of conventional oxide ion conductor (Y0.08Zr0.92O2-δ; 2.810-3 S/cm at 600 °C and Ea ~0.87 eV).

Efficient capture of barium (Ba) from solution is a serious task in environmental protection and remediation. Herein, the capacity and the mechanism of Ba adsorption by natural and iron(III) oxide (FeO) modified allophane (ALO), beidellite (BEI) and zeolite (ZEO) were investigated by considering the effects of contact time, temperature, pH, Ba2+ concentration, adsorbent dosage, the presence of competitive ions and adsorption–desorption cycles (regenerability). Physicochemical and mineralogical properties of the adsorbents were characterized by XRD, FTIR, SEM with EDX and N2 physisorption techn
