“…Nano assistant materials have a made surface and extended distortion ness on the boundary of particles, which is of unimaginable noteworthiness in radiation-heterogeneous shapes with their back, as well as in the midst of the progression of significantly tricky locators of ionizing radiation. To alter physicochemical properties, materials based on the blends of nano-measured oxides are created [16][17][18][19][20][21][22][23][24][25].…”

The study of physicochemical properties of nano-ZrO2+3mol.%Y2O3 was determined. The X-ray diffraction spectrum of the nano-ZrO2 and system nano-ZrO2+3 mol.%Y2O3 compound was drawn by the Ritveld method and the crystal structure was determined at different temperatures (T = 373, 473, 573, 673 K) and under normal conditions. The energy of the arrangement of H2 as a result of the decay of H2O, on the surface of nano-ZrO2+3mol.%Y2O3 was considered. Impacts of adsorption and desorption preparation of ZrO2+3mol.%Y2O3 nanoparticles were considered at diverse (T = 373, 473, 573, 673 K) temperatures. The thought of H2 in warm forms at nano-ZrO2+3mol.%Y2O3 framework expanded. This tells about hydrogen era by water part in close future. Nano-ZrO2 and system nano-ZrO2+3mol.%Y2O3 with the temperature range of T = 373, 473, 573, 673 K have been studied by SEM analysis. These results are promising of hydrogen generation by water splitting in near future.

“…This shows that water molecules are adsorbed from the atmosphere on the surface of ZrO2-based nanoparticles leads to the realization the process of localization of an electron from the crystal lattice of nanoparticles and its transfer outside the particles. In another work Droshkevich A.S. et al [8] reported on the direct conversion of the energy of adsorption of water into electricity on the surface of zirconia nanoparticles when doped with 3 mol% Y2O3. Titanium dioxide nanoparticles have many properties in common with ZrO2 nanoparticles.…”

In this work, using theoretical calculations within the framework of the density functional theory, taking into account the dispersive VDW interaction, the processes of adsorption and interaction of a water molecule with a TiO2 surface in various configurations are investigated. At the atomic / molecular level, the interactions of a water molecule with a TiO2 surface have been studied for various orientations. The results of calculations within the framework of DFT + VDW show that the adsorption energies of single water molecules in different initial positions on the substrate surface vary from -0.72 to -0.84 eV, and the most stable adsorbate structure is the TiO2 + H2O system upon adsorption of a molecule of water, parallel to the Y axis, because during the adsorption of H2O parallel to the Y axis, some favorable effects are observed in the band structure of titanium dioxide. On the one hand, the band gap decreases to 2.59 eV, and on the other hand, a new energy state appears in the band gap with an energy contribution of 0.17 eV, when water is physisorbed and interacts with a titanium atom at a distance of 2.12 Å and occupies a perpendicular position relative to the surface.

“…As a result, the material consists of plate-like grains preferentially oriented under external conditions (e.g., a magnetic field or a uniaxial pressure). In addition to the mentioned fabrication techniques, spark plasma sintering or direct hot pressing of MAX phases not allowing formation of highly textured material, still may result in formation comparatively distinct MAX phase regions along the boundaries of titanium grains in Ti and Cr based composites [13,52,[61][62][63][64][65]. It is also known about an anisotropy of mechanical properties of bulk MAX phases.…”

Advanced Ti-based composites are promising for applications in components of modern aircraft and rocket engines as well as other power equipment owing to their high strength-to-weight ratio and fracture toughness in a temperature range of 20 °C to 650 °C. However, there is a need to increase their operating temperature range up to 700−800 °C. In this work, mechanical behavior of Ti–Si–X composites (X=Al and/or Zr, Sn, C) has been studied. For comparison, mechanical behavior of Ti–Cr–X composite (X=Al and/or C) has been studied. As-cast and thermo-mechanically deformed series of beam specimens were examined. Strength tests of specimens were performed under three-point bending in a temperature range of 20 °C to 1000 °C. Single-edge notch beam (SENB) tests under three-point bending of specimen series were carried out in a temperature range of 20 °C to 900 °C for estimating fracture toughness of materials. Based on the constructed dependences of fracture toughness and strength on testing temperature for the specimen series as well as the microstructure and failure micromechanism analyses, the role of ultra-fine alloying elements in achieving good high-temperature strength and fracture toughness of the studied composites was substantiated.
