Conducting interdisciplinary research in the fields of chemistry and ecology (monitoring the quality of natural waters), physics and mathematics (calculation of HTNP stability of materials), chemistry, materials science and nanotechnology (forecasting the thermodynamic stability of nanomaterials - phosphors, research of antioxidant properties of newly synthesized coumarin derivatives). The main scientific results planned to be obtained in accordance with the Terms of Reference were achieved: 1) the results of monitoring the quality of drinking water of the sources of decentralized water supply in the city of Vinnytsia according to organoleptic and physicochemical indicators were obtained. 2) Knowledge was gained about the antioxidant properties of newly synthesized dihydroxy-derived coumarins. 3) The ranges of thermodynamic stability and the limit of isomorphous substitutions in HTSCs of the composition La1–xLnxFeAsO1−y, where Ln = Ce–Er and Y were established. 4) Mathematical modeling was carried out and the rangess of thermodynamic stability of nanomaterials based on solid solutions of Gd1–xLnxF3, Ln=Sm-Lu, Y. were determined.
