Protective hydrophobic coatings fabricated by plasma polymerization at atmospheric pressure, principal investigator
Annotation: A new type of intermediate electrode separator for alkaline electrolysis of water has been prepared by plasma-initiated grafting of acrylic acid on porous polymer membranes. Continuous coating of the porous structure of the membranes with polyacrylic acid has been shown to give these separators very favorable properties. Polyacrylic acid solvates in aqueous electrolytes and fills the membrane pores with a gel that significantly reduces the permeability of gases dissolved in the electrolyte, thereby suppressing cross-contamination of the hydrogen and oxygen produced. At the same time, the electrical conductivity of the separators is not significantly limited. The achieved properties of the separators are especially required in the operation of variable power electrolysis, especially in the conversion of energy from time-varying sources such as photovoltaics and wind energy in Power-to-Gas applications.

Modern plasma technologies for ecologic agriculture and food industry , principal investigator
Abstract: The aim of the project is to study atmospheric NTP generated by different types of resources relevant for application in agriculture to different types of plant models. The research is focused on evaluating the overall effect of NTP on seeds and dried fruits. The effects of plasma will be investigated on changes in physicochemical properties on seed surface, on the growth, physiological, biochemical, molecular-biological and anatomical aspects of plants after plasma treatment of the seeds, and the potential genotoxic or antigenotoxic effect. It also includes the study of the influence of plasma on plant resistance and the initiation of an adaptive response to environmental stressors (heavy metals, salinity, etc.), which is currently a highly topical issue in the adaptation of agriculture to climate change changes and pollution of the environment. One of the main objectives of the submitted project is to verify the effectiveness of the prototype device based on Diffuse coplanar surface dielectric barrier discharge in an industrially relevant seed treatment environment in order to improve the germination parameters for which chemical treatment (pickling) is used as 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, co-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.

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.

APVV-21-0147 (2022-2026) Advanced plasma technologies applicable in agriculture for surface treatment of seeds and dried fruits
Principal investigator
Low-temperature plasma (LTP) generated at atmospheric pressure in air has been already successfully used for inline surface treatment of textiles, glass, wood, synthetic polymers, and natural organic materials. Due to the highly reactive environment, the plasma is also applied in biological decontamination and sterilization of surfaces, in medicine and agriculture. The effects of plasma treatment on plant seeds lead to an increase in germination, acceleration of growth dynamics and plant vitality, as well as a decrease, or elimination of undesirable pathogenic
microorganisms on the seed surface.
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.
