AreaThe research is focused on the design, preparation, and characterization of molecules and (nano)materials with unique properties that can be used in industrial, environmental, and medical applications. We delineate the properties of prepared materials in details using a wide range of modern and advanced techniques. University students are actively participating in the research. We also supervise a number of doctoral dissertations. The results of our scientific work are also used in application outputs.
1. Light-responsive inorganic molecules and materials
The research is focused on the synthesis and characterization of new molecules, nanostructured materials, and luminescent (nano)materials and photosensitizers of singlet oxygen. The main emphasis is put on their stability, photostability, low toxicity, phototoxicity, biocompatibility with regard to their use as stable luminescent materials or in biology. In particular, we study the following systems:
2. New materials for a sustainable environment
Our research effort is focused on the development of new materials for environmental applications such as the purification of contaminated air, surface water and soil and the reduction of power consumption.
In cooperation with industrial partners, we focus on the development of construction materials and materials for environmental applications:
