| Annotation: | Radiosensitive optical fibers represent a promising alternative to common scintillators for their possible application in distributed sensors of high-energy radiation. Ce3+-doped garnets represent a large group of scintillators which can be implemented into optical fibers.
We address the knowledge gap on the effect of the chemical composition of Ce-doped A3Al5O12 garnet nanoparticles, where A=Y, Ho, Er, Tm, Yb and Lu, and their radioluminescence properties. Selected compositions will be implemented into optical fibers. To prepare radioluminescent optical fibers we will use two complementary approaches: Modified chemical vapor deposition combined with nanoparticle doping and rod-in-tube drawing of sintered nanoparticle-doped glass. The processing parameters will be studied to improve the radioluminescence properties of the fibers.
The proposed fibers can improve the properties of radioluminescence sensors of high-energy and harmful radiation. Their implementation in distributed sensors can respond to public demand for improved safety of nuclear facilities and devices. |

| Annotation: | The project goal is the preparation of a high-entropy alloy suitable for hydrogen storage. The alloys will be prepared by casting very small melts and mechanical alloying. Casting will allow rapid testing of a wider range of alloy concentrations, as it is not as time-consuming and does not require complex optimization of preparation parameters as mechanical alloying. High-energy milling will also be used for the mechanical activation of the cast and subsequently, crushed materials. Continuous analyses of the mictrostructure, chemical and phase composition and analyses of sorption capabilities, including cycling adsorption and desorption tests, will also be carried out throughout the duration of the project. Artificial intelligence will be actively involved in alloy research and development. |
