Interaction of low-temperature plasma and their components with biological material in agriculture and food industry, the principal investigator

The project aims to study the interaction of low-temperature plasma generated at atmospheric pressure with the surface of biological materials and to determine the influence of individual plasma components (active particles, radiation, electric field, and temperature) on physico-chemical surface properties and biological processes. The plasma systems relevant to practical application in plasma agriculture and the food industry based on dielectric barrier discharges and plasma jets will be investigated. Separation of the individual plasma components and elucidation of their influence on biological samples, the study of potential synergistic effect and optimization of conditions for plasma treatment of plant matrices is an important step in designing suitable plasma sources for specific applications and using plasma technologies in practice as an alternative and more environmentally friendly approach in agriculture and food processing.

Advanced plasma technologies applicable in agriculture for surface treatment of seeds and dried fruits, the co-investigator

The aim of the project is to study atmospheric pressure LTP generated by different types of plasma sources relevant for application in agriculture to various types of plant models. The research is focused on evaluating the overall effects of LTP on seeds and dried fruits. The effects of plasma will be investigated on changes in the physicochemical properties on the seed surface, on the growth, physiological, biochemical, molecular-biological and anatomical aspects of plants after plasma treatment of seeds, and the potential genotoxic or antigenotoxic effects. It also includes a study of the plasma effects on plant resistance and the initiation of an adaptive response

to environmental stressors (heavy metals, salinity, etc.), which is currently a highly current issue in the adaptation of agriculture to climate changes and environmental pollution.

One of the goals of the presented project is to verify the effectiveness of the proposed prototype device based on Diffuse Coplanar Surface Dielectric Barrier Discharge in an industrially relevant environment to improve germination parameters, for which chemical treatment (seed dressing) is standard. This method represents a promising economically and ecologically advantageous technology for the treatment of plant seeds intended for sowing, germination, storage and consumption.

The study of plasma-chemical processes in the preparation of inorganic nanofibers by method of plasma assisted calcination, the principal investigator

The aim of the project is study of plasma assisted calcination (PAC) in the preparation of inorganic nanofibers. The PAC of metal-organic fibers with the use of low-temperature plasma appears to be a prospective alternative to conventional thermal calcination. Thermal calcination is a high temperature (~100°C) long-term (several hours) process for removing of the polymer matrix and oxidation of precursor from polymer/precursor fibers to form inorganic nanofibres. Low-temperature non-equilibrium plasma is a chemically active environment, and with the use of a working gas with high oxidation potential, it is possible to produce ceramic nanofibers in significantly shorter time at lower temperature.

Modern plasma technologies for organic agriculture and food industry, the co-investigator

The project focused on the application of low-temperature plasma generated at atmospheric pressure for the treatment of biological material in agriculture and food industry for improvement of germination, growth dynamics and plant vitality, as well as for elimination of undesirable pathogenic microorganisms on the surface of seeds (and fruits).

The use of low-temperature plasma is an environmentally and economically appropriate method for the gentle treatment of seeds of plants intended for sowing (cereals, legumes and others) and stored agricultural commodities (especially cereals, nuts,

dried fruits) and for the human and animal nutrition and is a preferred alternative, or an additional method to the traditional treatment of seeds with chemical agents.

Functionalization of polymer surfaces using plasma generated in liquids, the co-investigator

The aim of the project was modification of polymer materials (permanent hydrophilicity, antibacterial treatment and immobilization of functional groups) by using low-temperature method using plasma generated in liquid medium.

The grafting of the functional groups with the desired properties on the polymer surface at different conditions of plasma generated in the liquid medium will be studied by modern diagnostic methods. At the same time the physical mechanism of the discharge in the liquids will be studied. New methods of plasma surface treatment of polymer materials will enable their application in many fields of textile, automotive, building and energy industry as functional and technical textiles, filtration and transfer media, membranes and separators. 

The non-equilibrium plasma source based on a

high voltage pulsed diaphragm discharge in a liquid medium is an alternative method for treatment of the

polymers surfaces.

 Protective hydrophobic coatings fabricated by plasma polymerization at atmospheric pressure, co-investigator

Hydrophobic surfaces are used in many applications due to their self-cleaning, anti-corrosion, and anti-icing properties. They can be formed using hydrophobic coatings in a number of ways, including the use of low-temperature plasma, which is an environmentally and cost-effective alternative to conventional chemical methods. In recent years, attention has been paid mainly to plasma technologies at atmospheric pressure, due to their simpler technical design and lower financial demands compared to low-pressure plasma. The project aims to study the preparation of hydrophobic or superhydrophobic layers on various surfaces by plasma polymerization at atmospheric pressure. Research will focus to clarify the plasma-chemical processes affecting the plasma polymerization process and a deeper understanding of the physico-chemical mechanisms responsible for the formation of a layer with optimal hydrophobic properties.
