Research on the correlation dependences of magnetic, structural, and optical properties of aluminate glasses, titanium alloys, and titanium-based nanocolloids, and ion liquids
Výskum korelačných závislostí magnetických, štruktúrnych a optických vlastností hlinitanových skiel, titánových zliatin a nanokoloidov na báze titánu a iónových kvapalín
Program: SRDA
Duration: 1.1.2025 – 31.12.2028
Project leader: Mgr. Škrátek Martin, PhD.
Annotation: The project focuses on the development of magnetic measurement methods for selected areas of materialsresearch and biomedicine, for a deeper understanding of the physical and chemical properties associated withchanges in the distribution of electrical charges, and for their utilization in designing revised technologicalprocedures and diagnosing surface properties. First goal of the project is to investigate the influence ofcomposition, precursor powder preparation methods, and the preparation method of aluminateglasses/glass-ceramics on their structure and magnetic properties. The second goal is the investigation of theinfluence of properties and composition of ion liquids on the phase composition, shape, size distribution, andstability of titanium-based nanoparticles and nanostructures. The physicochemical and magnetic properties ofnanocolloids will be studied with attention to the surface properties of biomedical Ti-alloys, especiallynanostructures based on titanium oxide.
SQUIDiron – Determination of Iron in blood and tissues of laboratory animals using SQUID magnetometer.
Stanovenie množstva železa v krvi a tkanivách laboratórnych zvierat pomocou SQUID magnetometra
Program: Plán obnovy EÚ
Duration: 1.9.2024 – 31.8.2026
Project leader: Mgr. Škrátek Martin, PhD.
Annotation: Iron is an essential chemical element that is part of many metabolic processes. However, the amount of iron in the body must be balanced, as its excess or deficiency can lead to serious health conditions. Iron is found in the body in ferritin, hemoglobin or transferrin proteins. Deoxyhemoglobin, methemoglobin, and myoglobin are known to exhibit paramagnetism, which originates from the Fe2+ Fe3+ ions embedded in their molecules. Ferritin, as an iron storage protein, contains Fe atoms mineralized in the form of oxyhydroxide nanoparticles, whose behavior is superparamagnetic. SQUID magnetometry offers the possibility of detecting and quantifying different forms of iron with high sensitivity and could be more useful than other established methods (colorimetric, spectrophotometric, histochemical or atomic absorption spectrometry) in determining the amount of iron in small samples.
