Laboratory Classes in Plasma Chemistry
FCH-MAO_PLA_PAcad. year: 2019/2020
Basics of vacuum technique and low pressure measuring, optical emission spectroscopy,, radiofrequency discharge at low pressure, ozone generation, diaphragm discharge in liquids and its application, surface treatment of polymers, EPR spectroscopy of decaying plasmas, VOC decomposition in plasma at atmospheric pressure.
Learning outcomes of the course unit
Students obtain practice knowledge with plasmachemistry background, plasma diagnostics and with selected plasmachemical applications and technologies in laboratory scale, too.
Practice couses from inorganic and physical chemistry and practical course from physics.
Recommended optional programme components
Recommended or required reading
Chen F., Chang J. P.: Principles of plasma processing. Kluwer Academic, Plenum Publishers. New York 2003. (EN)
Planned learning activities and teaching methods
The course uses teaching methods in form of Laboratory exercise - 3 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.
Assesment methods and criteria linked to learning outcomes
Working group gives one protocol form each practical task together. The classification is dependent on the average protocol level and also on the work during the exercises.
Language of instruction
List of tasks:
1. Low pressure measuring
2. EPR spectroscopy of plasma
3. Optical emission spectroscopy of plasma
4. Changes of polymer materials wettability by surface discharge
5. Permeability enhancement of non-wowen textile materials
6. Electrical characteristics of diaphragm discharge in water solutions
7. Hydrogen peroxide generation by diaphragm discharge in liquids
8. Organic dyes degradation by diaphragm discharge in liquids
9. Study of ozone generation in dielectric barriere discharge
10. Plasmachemical removal of corrosion layers on corrode metal materials
11. VOC destruction in dielectric barriere discharge combined with photocatalyzis
The course gives the practice knowledge in plasmachemistry background, plasma diagnostics and with selected plasmachemical applications and technologies, too.
Specification of controlled education, way of implementation and compensation for absences
Attendance is required and preparedness for independent working on the experiment is checked by teacher. Students work in small groups (usually two students).
