AB  - Energy level positions, refractive index values, Judd–Ofelt (JO) intensity parameters, Slater integrals, and spin-orbit coupling parameters are taken from the literature for 27 Dy3+-doped materials (five crystals and 22 glasses). Investigated are only the transitions that are used for the Boltzmann-type luminescence intensity ratio (LIR) thermometers (transitions from the three thermalized levels, 4F9/2, 4I15/2, and 4G11/2 to the ground level). Reduced matrix elements of these three transitions are calculated from the Slater integrals and spin-orbit coupling parameters and they are compared to the most frequently used values from Carnall's tables. The comparison of JO parameters shows the smaller variation of the Ω6, related to rigidity, in crystal hosts than in glasses, and the opposite was observed for the Ω2,4 parameters. LIR performances are simulated by the JO thermometric model for each material by the conventional LIR and the LIR that exploits the third thermalized level. The comparison of the predicted figures of merit in luminescence thermometry reveals the most promising thermometric Dy3+ doped crystals and glasses. © 2022 Wiley-VCH GmbH

AB  - Topological properties can make light field remarkably robust to various external perturbations. The ability to control and change on demand topological characteristics of light paves the way to new interesting physical phenomena and applications. Here, numerical modelling design of the device based on active multi-core fiber that can change topological charge of the state of light has been proposed. The concept is based on the nonlinear dynamics of optical vortices in active multi-core optical fiber with linearly coupled cores, saturated gain, and constant linear losses. Results demonstrate that the proposed system can provide change of the topological charge of vortices.

AB  - In this work a review of the currently available methods for carbon dioxide removal from flue gasses is given. Some of them are commercially available, while others are still under development. Special attention is given to detailed description of the methods based on hemi sorption by aqueous solutions of alkanolamines, which found wide commercial use in industry. Selection of appropriate absorbent, process equipment, methods, working parameters, combustion processes, etc., are some of the key points that will be reviewed within this work in order to present advantages and limitations of carbon dioxide removal methods. In the experimental section we have provided data on density, viscosity and refractive index of insufficiently investigated carbon dioxide removal agents, such as monoisopropanolamine (MIPA), diisopropanolamine (DIPA), triisopropanolamine (TIPA) and currently widely used dietanolamine (DEA). The data obtained are crucial for the equipment design and process optimization.
