APVV-19-0386, 2020-2024, Ion and electron processes for advanced spectrometric methods, co-investigator 



Molecular processes induced by electrons and ions are abundant in many different environments such as interstellar space, atmospheres of small bodies and planets, natural and industrial plasmas, novel nanotechnologies such as focused electron and ion beam etching and deposition, analytical methods or even in agricultural applications. The main goal of current basic research project will be understanding the processes associated with electron and ion interactions with gases, including electron ionisation, electron induced excitation and dissociation, electron attachment, and finally the interaction of positive and negative ions with the molecules in detail. The studies will cover the field of the kinetics of the processes (cross sections and rate coefficients), and energetics of the reactions (analysis of the reaction products and energy thresholds for their formation). The experimental studies will also be supported by quantum chemical calculations when needed. To reach the project goals the Electron and Plasma Physics Laboratory (EPPL) at the Comenius University Bratislava will use advanced spectrometric methods – emission spectroscopy, mass spectrometry and ion mobility spectrometry which will provide complex understanding of the analysed group of processes. The EPPL utilizes unique combination of experimental devices aimed specifically at studying these elementary processes. During the course of the project all the experimental methods will be further developed to broaden their capabilities and applications. The project will also draw support from the run-in cooperation of the EPPL with excellent research organizations such as Auburn University, USA in the field of astrophysics, University of Kent, UK in the field of plasma jets and discharges or National Research Nuclear University, Russia in the field of ion spectrometry. The project will generate publications in the renowned international current journals and several PhD, master and bachelor theses.

Modern plasma technologies for ecologic agriculture and food industry , co-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.

VEGA 1/0733/17, 2017-2020,


This project was focused to low=energy electron interactions with molecules and molecular clusters in gas phase. The molecular targets are relevant for novel technolgies of electron induced deposition, small hydrocarbons and their deuterated derivatives relevant for edge plasma processes in thermonuclear fusion. Results can be used for further modelling of surface processes at high-energy electron induced deposition, at plasma processes and technologies.

APVV-15-0580, 2016-2020,Electron and ion interactions with molecules and their applications in analytical and diagnostic methods, co-investigator



The project is focused on development of new ion sources for Atmospheric Pressure Chemical Ionisation (APCI) on the basis of electric discharges for ultra high sensitive analytical techniques based on Ion Mobility Spectrometry (IMS) and mass spectrometry (MS) and their combination (IMS-MS). Additionally, we plan to develop atmospheric pressure electron gun as ion and photon source for the analytical techniques. The research of new ionisation methods will be complemented by fundamental research of electron induced ionisation and excitation processes and ion-molecule reactions relevant to the diagnostics and understanding of the operation of the ion sources. The results of the fundamental studies we plan to apply for analysis and detection of chemical compounds (phthalates and derivatives of aromatic molecules) using the IMS, and IMS-MS methods.
