Research group

Magnetic Hyperthermia and Polymer Memristors

Research in this area focuses on the preparation of materials for various applications of conductive, dielectric and magnetic materials, from electromagnetic shielding, selectively reflective surfaces and selectively permeable plate materials, to the materials intended for the hyperthermic treatment of cancer, which have already been patented.

The material design is mainly focused on the preparation of magnetic nanoparticles, possibly also on the application or modification of magnetic and other fillers (particles and short fibres) from commercial sources into composite materials with a polymer matrix. In the field of synthesis, the group also successfully works with polyaniline and similar conductive polymers. The combination of a magnetic inorganic core and an electrically conductive polymer shell creates a core-shell particle with significantly improved properties. The ability to convert the absorbed energy of an alternating magnetic field into heat is used in cases which require a heat source in volume; in the most demanding application it is hyperthermia. The mentioned materials are also used to produce conductive composites for electromagnetic shielding. Selective reflectivity is then achieved by the preparation of so-called metamaterials, where, in addition to the material composition, the geometry of the individual components of the composite contributes to the function. Flat structures with material patterning are prepared by material printing methods.

Sino-EU Joint Laboratory of New Energy Materials and Devices

In recent years, the development of energy storage devices has been carried out in two main directions: supercapacitors (SC) and lithium batteries, i.e. lithium-ion (Li-ion) and lithium-sulphur (Li-S) batteries. SCs are characterized by high power density, short charging time, long life and reliability. In addition, They can potentially withstand more than one million charge/discharge cycles without a significant decrease in capacity or increase in internal resistance. Although SCs have significantly higher power in the same volume, they are not able to store the same amount of energy per unit weight and volume as lithium-based batteries. In addition, the cost per unit of SC energy is more than 20 times higher than in the case of batteries. The main disadvantages of Li-ion and Li-S batteries, on the other hand, include a high degree of self-discharge and low cyclic stability. To overcome the above-mentioned problems of existing energy storage facilities, research at the Sino-EU joint lab focuses on the development of nanostructured porous electrode materials with high pseudo-capacity, i.e. carbon electrodes modified with redox active components (conductive polymers, oxides and sulphides of transition metals). The developed cathode materials are designed for both batteries with organic electrolyte and water-based electrolytes. Special attention is paid to the development of gel electrolytes with a set of properties required for a certain type of energy source. Another important direction of the Sino-EU joint lab is the development of a photovoltaic power device integrated with a supercapacitor for collecting ambient energy and self-charging without the use of an external source.

Research group

Energy and Medical Composite Systems

The subject of interest of this research group is the study and preparation of matrices for advanced biocomposite systems as well as active/functional components that can be incorporated into these matrices. The matrices are mainly polymer gels made of synthetic and natural biocompatible and biodegradable polymers. A special case is the use of bacterial cellulose from the team´s own production in bioreactors. These gels are used, for instance, as cover wounds in medicine, in pervaporation processes and are also applied (in cooperation with the group of Composites with electrical and magnetic properties) as an electrolyte in supercapacitors. Mineralized gels serve as templates in bone replacement surgery. The carbonate-based filler is prepared directly in the structure of the gel matrix by the biomimetic mineralization method. As functional agents, synthetic polypeptoids and peptoid nanoplates, which have significant biological activity, are used.

Socio-economic Aspects of Energy

The current transition of power industry from fossil fuels to renewable energy sources forms the basis of the ongoing transformation of the global energy sector. In this context, many scientific questions arise, including the types and forms of participation of different stakeholders, ownership issues, financial implications and other socio-economic aspects.

The requirements for future energy systems can be summarized in three key trends: decarbonisation, decentralization and digitalisation, with a tendency towards empowering consumers. The current structure of energy markets only partially reflects these visions. Therefore, it is necessary to examine the relationship between the energy systems and society from the multidisciplinary viewpoint in the following basic research directions:

  • Decarbonisation due to energy price volatility, innovation in the renewable energy sector and environmental impact assessment;
  • Decentralization using innovative business models such as peer-to-peer trading, blockchain and diversification of stakeholder structures with greater consumer engagement (energy prosumers);
  • Digitization and creation of IT platforms for smart grids, optimization of energy production and consumption, including storage.
