In this work, we report on an investigation of the ytterbium diffusion characteristics in lithium niobate. Ytterbium-doped substrates were prepared by in-diffusion of thin metallic layers coated onto x- and z-cut congruent substrates at different temperatures. The ytterbium profiles were investigated in detail by means of secondary neutral mass spectroscopy, optical microscopy, and optical spectroscopy. Diffusion from an infinite source was used to determine the solubility limit of ytterbium in lithium niobate as a function of temperature. The derived diffusion parameters are of importance for the development of active waveguide devices in ytterbium-doped lithium niobate.

Objective: The creation of the medicine for a local radiomodification of tumors.Methods: The level of the secondary radiation on the surface of the phosphate glass powder with the inclusion of tantalum oxide processed by 6 MeV deceleration emission was studied. Medical linear accelerator TrueBeam (Varian, USA), and Semiconductor diode detector PDI 2.0 (Sun Nuclear Corp., USA) having the system of moving in vertical plane and the system of position video recording were used.Results: The presence of the phosphate glass (containing 20% Та2О5) on the surface gave a 63.7% increase to the secondary radiation. It’s around two thirds of the overall level.Conclusion: An opportunity to create a medicine on the basis of phosphate glass, containing tantalum oxide, for local radiomodification of malignant tumors.

AbstractThe process of bone regeneration in bone grafting procedures is greatly influenced by the physicochemical properties of the bone graft substitute. In this study, porous phosphate glass (PPG) morsels were developed and their physicochemical properties such as degradation, crystallinity, organic content, surface topography, particle size and porosity were evaluated using various analytical methods. The in vitro cytotoxicity of the PPG morsels was assessed and the interaction of the PPG morsels with Dental Pulp Stem Cells (DPSCs) was studied by measuring cell proliferation and cell penetration depth. The cell-material interactions between PPG morsels and a commercially available xenograft (XG) were compared. The PPG morsels were observed to be amorphous, biocompatible and highly porous (porosity = 58.45%). From in vitro experiments, PPG morsels were observed to be non-cytotoxic and showed better cell proliferation. The internal surface of PPG was easily accessible to the cells compared to XG.
