Cold plasma for innovative agriculture: effect of cold plasma treatment on the seed germination and seedling development

Recently, we hosted a Ph.D. student from Kathmandu University - Rajesh Prakash Guragain (Deepak Prasad Subedi's Lab). Rajesh participated in the short research internship (3-30.03.2022) aimed at taking measurements with the use of unique equipment available at the Department of Molecular Engineering (PROM programme-NAWA). He worked on the surface modification of different kinds of seeds (radish, carrot, soybean, wheat, etc.) by cold plasma treatment toward enhanced germination.  The research was focused on a deeper understanding of the mechanisms of plasma-seed treatments.
A cold plasma technology has shown great potential in seed processing technology for agricultural purposes!

Electrical properties of cold plasma produced thin nanohybrid layers based on the carbon family


Together with M. Sc. Kaya Chakmak, our guest from the ERASMUS programme (Akdeniz University, Turkey), we have investigated the conductivity of cold plasma-produced Sn-C and Co-C thin nanohybrid films. Based on macro-scale current-voltage characteristics and nano-scale measurements using conductive atomic force microscopy (CAFM), we have obtained results interesting for the potential application of the layers for water splitting into hydrogen and oxygen.

Novel plasma-deposited photocatalysts for photoelectrochemical water-splitting


The partnership agreement between the Lodz University of Technology and Research Institute of Electronics (RIE) of Shizuoka University (Japan) resulted in a recent visit of PhD student of RIE Shizuoka University, Vytautas Kavaliunas, to our Department. MSc Kavaliunas participated in the short form of education aimed at taking measurements with the use of unique equipment of the Department of Molecular Engineering and obtaining materials for a PhD thesis.
During his stay, Vytautas Kavaliunas together with the team members, established a method of TiO2 thin films preparation via cold plasma deposition (PECVD), as a top layer of novel multi-layer anode for the photoelectrochemical water-splitting process.
Electrochemical water decomposition with the use of solar irradiation is one of the most prospective way of green hydrogen production, however, there is an urgent need for efficient photoactive catalysts development for this purpose.
Novel photocatalysts were studied using XPS, UPS and UV-Vis spectroscopy techniques. Furthermore, photocatalytic properties of the complex anodes were examined via electrochemical LSV analysis of oxygen evolution reaction (OER) in the basic electrolyte solution. The study of the water splitting process with the use of obtained anodes will be continued both in the Department of Molecular Engineering and RIE, Shizuoka University.

Thin layers deposited by cold plasma for electrochemical applications - collaboration with the Jagiellonian University and AGH University of Science and Technology

Another new research topic has been started during the recent stay of Maria Madej (PhD student from the Jagiellonian University in Cracow, Faculty of Chemistry, Department of Analytical Chemistry, Supervisors: Prof. Jolanta Kochana, Prof. Bogusław Baś) and Justyna Lipińska (PhD student from the AGH University of Science and Technology in Cracow, Faculty of Materials Science and Ceramics, Faculty of Analytical Chemistry, Supervisor: Prof. Bogusław Baś). Preliminary tests were conducted on new layers applied using a cold plasma for applications in the construction of electrochemical sensors. Our research is focused on optimizing the layering parameters to achieve the best electrical conductivity while maintaining the high mechanical strength of the formed  layers.

Cold plasma for a rational modification of MOFs – collaboration with the Universitad Rey Juan Carlos (Madrid)

New research topic has been started during the recent stay of Jesus Tapiador Cebrian in our labs in July 2019 (PhD student from the Universitad Rey Juan Carlos, Chemical and Environmental Engineering Group, supervisors: Prof. Guillermo Calleja, Dr Gisela Orcajo).  A cold plasma treatment has been applied for a rational modification of MOFs developed by Spanish group.  Metal-organic frameworks (MOFs) are advanced functional materials with very high porosity and well-defined structure. Our research is focused on optimizing their structural and functional characteristics for improved performance as catalysts (CO2 conversion, dye degradation) and also as hydrogen storage materials.
