Jianyu Feng (冯建宇) has been focusing on the research of low-temperature plasma since he was studying for his master's degree in China. Here in Brno, he works under Dr. Richard Krumpolec's guidance on the surface modification of rough, structured, and curved materials by thermally non-equilibrium atmospheric pressure plasma as his Ph.D. research topic. Jianyu is successful. He has recently received the Young Scientist Award for his oral presentation at the XX. International Conference on Plasma Physics and Applications (CPPA 2023) in Romania. He has also been on an internship in Bratislava through a mobility project funded by the A.6 Program of the Faculty of Science.
Jianyu Feng came to pursue his Ph.D. studies in Brno due to his interest in low-temperature plasma physics research. He came across many scientific publications on the topic that DPE and CEPLANT scientists reported. He contacted Prof. Černák and expressed his desire to study in Brno. His doctoral research focuses on developing new plasma sources and surface modification of rough, structured, and curved materials by low-temperature plasma. He adds, "In modern society, environmental problems are prominent, and energy is in short supply, which puts forward higher requirements for being environmentally friendly and efficient. Low-temperature plasma has many advantages, such as a simple controlled process, convenient operation, environmentally friendly, energy and cost-saving, fast, efficient, and so on. It can generate a wide variety of active particles through a simple device. It is precisely because of its advantages that it is widely used in the industrial field."
In Brno, Jianyu Feng has been focusing on developing new plasma sources for some time now. He and his colleagues designed a plasma source capable of generating temperature-friendly and effective long-distance plasma, which will have great potential in biomedicine or complex surface modification of materials. The ion mobility spectrum (IMS) and mass spectrum (MS) diagnoses are practical tools for studying low-temperature plasma. Through his internship in Bratislava (from May 2023 to June 2023), he got acquainted with these techniques and can now utilize them in his research. The Ion mobility spectrometry lab in the Faculty of Mathematics, Physics, and Informatics, Comenius University in Bratislava, has extensive experience and made many remarkable achievements in ion mass spectrum and mass spectrum diagnostics.
