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.Scientific topics 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.
Applications In cooperation with industrial partners, we focus on the development of construction materials and materials for environmental applications: Inorganic systems for 3D printing technology (Z. Černý) ZnO nanosols with self-cleaning properties for the treatment of repair of contaminated building surfaces with algae or mold (Z. Černý) Nanoparticles for water treatment and stabilization (Z. Černý) Powder materials for rapid deactivation of chemical warfare agents (J. Henych) Combined materials for radiation shielding and secondary ionizing radiation shielding (Z. Černý) Special concretes including inorganic materials based on original matrices for the nuclear industry. Coating systems for new concrete remediation technologies in the nuclear industry. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
