Investigators: M. Škrátek, J. Maňka   Measurement of magnetic quantities with high sensitivity finds application in various areas of scientific research. In our research, in cooperation with other scientific institutions, we focused on the use of nanoparticles in biomedicine and on two issues in the field of materials research. Ultra-small superparamagnetic iron oxide nanoparticles in…

Investigator: M. Majerová   Aluminous glasses are interesting in terms of their basic structure. Alumina glasses have excellent mechanical properties, excellent corrosion resistance, show better light and heat resistance and better light conductivity than conventional silicate glasses. Another important feature of these glasses is that they are permeable to ultraviolet, visible and infrared radiation and…

Investigators: M. Škrátek, A. Dvurečenskij, A. Cigáň, J. Maňka Biogenic iron is found in all biological systems. Recently, ultra-small superparamagnetic iron oxide nanoparticles have also been used in biomedicine, which, as drug carriers, enable targeted dosing by the action of a magnetic field. The stability of these nanoparticles depends on the cellular environment (chemical composition,…

Investigator: M. Majerová   Aluminate glasses are interesting in terms of their basic structure. The main net forming element is aluminum, while in conventional glasses it is e.g. silicon. Aluminate glasses have excellent mechanical properties, excellent corrosion resistance, show better light and heat resistance and better light conductivity than common silicate glasses. Another important property…

Investigators: A. Cigáň, A. Dvurečenskij, M. Škrátek, M. Majerová, J. Maňka Ionic liquids – liquids composed only of ions, have unique physicochemical properties, such as high thermal and chemical stability, the ability to dissolve various substances and negligible vapor pressure. These properties presuppose their use for the development of new technologies for the production of…

(Investigators: A. Cigáň, A. Dvurečenskij, M. Škrátek, M. Majerová, J. Maňka) Polycrystalline samples with a nominal composition of EuBa2Cu3-xSnxO7-δ, where x = 0 to 1.5, were prepared by the solid phase reaction method at 1050 ° C in an oxygen atmosphere. Their structural, superconducting and magnetic characteristics were analyzed based on the results of polarizing…

(Investigator: M. Škrátek) Biodegradable polymer nanocomposites represent a promising group of plastics usable for various bio- and enviro-friendly applications, such as drug carriers or biological plastics with shape memory. Polymers are generally electrically non-conductive and non-magnetic materials. Natural Halloyzite nanotubes (HNT) modified with iron oxide nanoparticles were used to improve the mechanical properties of the…
