“…The number of indentation measurements made it possible to establish the uniformity of changes in the strength properties of ceramics, as well as to determine changes in the diagonals of the indenter. Based on changes in the indenter imprint diagonals c/a (c is the crack half length, and a is the indenter imprint semi-diagonal), as well as the hardness value using formula (1), it is possible to estimate the value of the critical stress intensity factor (K 1c ) in the samples, which reflects the change in fracture toughness (crack resistance):…”

“…One of the directions for advancing the energy sector in both developed and developing nations, with the aim of reducing reliance on hydrocarbons and fossil fuels while elevating hydrocarbon neutrality, involves the exploration of new alternative energy sources, including nuclear and thermonuclear energy. In recent years, significant emphasis has been placed on research related to the development of novel blanket materials centered on lithium-containing ceramics [1][2][3]. These materials hold the potential to address the challenge of producing and accumulating tritium, the primary fuel for the thermonuclear cycle [4,5].…”

The paper presents the results of studies of the resistance of lithium ceramics to helium swelling during its accumulation in the structure of the near-surface layer, and the identification of the three types of lithium ceramics most resistant to radiation degradation: Li4SiO4, Li2TiO3, and Li2ZrO3. The simulation of helium swelling under high-dose irradiation was carried out by irradiation with He2+ ions with fluences of 1 × 1016 ion/cm2–5 × 1017 ion/cm2, which allows for simulating the implanted helium accumulation with a high concentration in the damaged surface layer (about 500 nm thick). The samples were irradiated at a temperature of 1000 K, the choice of which was determined by the possibility of simulating radiation damage as close as possible to real operating conditions. Such accumulation can result in the formation of gas-filled bubbles. Through the application of X-ray phase analysis, indentation testing, and thermophysical parameter assessments, it was ascertained that among the three ceramic types, Li4SiO4 ceramics exhibit the highest resistance to helium-induced swelling. These ceramics experienced less significant alterations in their properties compared to the other two types. An analysis of the correlation between the structural and strength parameters of lithium-containing ceramics revealed that the most significant changes occur when the volumetric swelling of the crystal lattice becomes the dominant factor in structural alterations. This phenomenon is manifested as an accelerated degradation of strength characteristics, exceeding 10%. At the same time, analysis of these alterations in the stability of thermophysical parameters to the accumulation of structural distortions revealed that, regardless of the type of ceramics, the degradation of thermophysical properties is most pronounced under high-dose irradiation (above 1017 ion/cm2).

High-level ab initio calculations were performed to determine the structural features, electronic characteristics, and transitional properties of LiSb+, which is a hitherto experimentally unknown diatomic cation. We acquired and evaluated potential energy curves, spectroscopic constants, and vibrational energy levels for low-lying Λ-S electronic states and their related Ω states. The spin-orbit coupling effect has a slight impact on these states. The transitional properties, such as transition dipole moments, Einstein coefficients, Franck-Condon factors and vibrational branching ratios, as well as the radiative lifetimes of transitions from excited Ω states to the ground state, have been identified and discussed. We anticipate that these prognostic results will act as guidelines for future research.
