December 2020: Seasons Greetings!

There has been a time when 'corona' was associtated with an inherent beauty - at least for the plasma physcicist. During the year 2020 this has changed and we are undoubtfully looking back at a year, which was 'challenging' for all of us. I still would like to wish all of you a good and peaceful time 'between the years'. Some time to reflect, enjoy and gather new strength.

Seasons Greetings 2020

November 2017: Graduations!

Congratulations are once more in order since two of our students very successfully defended their research and thesis. On November 29, Raphael Rataj passed the final hurdle in obtaining his Master of Science in Physics at the University of Greifswald for his research on "Investigation of Initiation and Development of Pulsed Discharges in Water." He will now continue this work as a PhD-student in our group.

One week earlier Robert Banaschik defended his doctoral research on "Potential of Pulsed Corona Discharges Generated in Water for the Degradation of Recalcitrant Pharmaceutical Residues and for Water Disinfection." For his excellent work he was awarded the doctorate degree of Dr. rer. nat. also from the University of Greifswald. He doesn't actually like his pictures to appear on the internet so his face is hidden here but I can assure you that he is really smiling. If you would like to learn more about Robert's work have a look at his publications.
Update Jan. 2, 2018: Robert really doesn't like any picture of him to be published anywhere at all. Upon his urgent request, his graduation image was hence removed. We wish him and his attitude all the best.

October 2, 2017: Congratulations Katja Zocher

Katja Zocher - 3rd prize It is a great pleasure for me applauding Katja for being awarded 3rd prize in the categorie "Food, Biotechnology and Environment" as a student in the Young Investigator Competition of the 2nd World Congress on Electroporation. The World Congress was held in Norfolk, VA, for and attracted more than 360 participants that discussed recent developements and results for the application of pulsed electric fields including medical therapies, environmental application and food treatment as well as many others. Altogether 49 students competed for the Young Investigator Awards. Katja was recognized for her talk on "Microalgal protein and pigment analysis after extraction with spark discharge treatment."

August 19, 2017: RCL-circuit solver available

A new tool is available in the 'pulsed power toolbox' which allows calculating peak currents and asociated rise times for RCL-circuits. Of course damping factors and frequencies are computed as well. It has been a while since I updated the toolbox - I hope you will enjoy the addition. Unfortunately I couldn't find anything comparable anywhere else.

July 21, 2017: Research Opportunities (Internships, bachelor degrees, master degrees, PhD degrees)

We are conducting interdisciplinary research on applications of pulsed electric fields and non-thermal plasmas. Main research projects and research directions are described somewhere else on this webpage. A lot of our studies are focused on investigation of physical processes but maybe an even greater part is dealing with an understanding of the interaction and responses of electrical stimuli, including plasma, with living matter, surfaces and materials, including especially liquid media. In addition, providing of electrical stimuli and generation of plasma, requires us to solve engineering challenges.
Accordingly, we have many research questions that provide research opportunities for students with an expertise and background in physics, biophysics, biochemistry, biology, pharmaceutical sciences, environmental sciences, material sciences, electrical engineering, pulsed power engineering, power electronics and others. To give you an idea of interdisciplinary topics that we had dealt with in the past, especially for internships and bachelor degrees, here are some examples (the list is by no means complete):
  • antimicrobial copper coatings on temperature labile materials deposited by dc atmospheric pressure plasma jet
  • growth stimulation of watercress by pulsed electric fields
  • comparison of electro-Fenton chemistry and plasma chemistry for waste water treatment
  • pulse forming line topologies for pulse generator development
  • switching characteristics of pressurized spark gaps
  • fast voltage and current diagnostics for nanosecond pulse generators
  • discharge dynamics of glow-like discharges in air
  • synergistic effects of non-thermal plasmas and pulsed electric fields for the inactivation of microorganisms

If you are looking for a research opportunity in our group, I encourage you to talk to us. Given the breadth and scope of our research it is quite common for us to work together with different academic institutions (universities, technical universities/ Fachhochschulen, research institutes) and different departments. Cooperations are not limited to institutions in Germany and therefore I encourage especially colleagues from abroad to get in touch if they would like to conduct research with us.

July 7, 2017: Prof. Dr. Andreas Neuber visits the INP

Prof. Neuber visited our institute to present a semínar talk on "VUV impact in atmospheric pressure plasma formation." The topic is of great interest to the plasma community and we are happy that Prof. Neuber discussed the findings of the Center for Pulsed Power and Power Electronics at Texas Tech University with us.

July 3, 2017: SPM-5 2017

It was our distngued pleasure to host this year's 5th International Workshop on Solution Plasma and Molecular Technologies (SPM-5). The meeting was held from June 25-29 at the INP. I'd like to thank once more all participants who found their way to Greifswald from around the world to share and exchange their reasearch with us.

September 25, 2014: It's been a long time...

...and an update on news from our group is long overdue. I feel bad about the lack of attention to our webpage since a lot of things have happened. Unfortuantely these busy times have also kept me from posting here, Several people have joined and in part already left our group again during the last 17 months.
We had the pleasure to host many distinguished colleagues from around the world for a short visit during the last year. All of them deserve a separate and dedicated note here. Instead I apologize once more that I'm only listing them here, in a somewhat reversed chronological order of their visit to the INP:
  • Dr. Eugene Stamate, Department of Energy Conversion and Storage, Technical University of Denmark
  • Prof. Dr. Jing Fang, Academy for Advanced Interdisciplinary Studies, Peking University
  • Dr. Pavel Babica, Research Centre for Toxic Compounds in the Environment, Masaryk University, Brno, Czech Republic
  • Dr. Petr Lukes, Institute of Plasma Physics, Prague, Czech Republic
  • Prof. Dr. XinPei Lu, Huazhong Unviersity of Science and Technology, Wuahn, China
I feel privileged that in the meantime I had actually a chance to return many of these visits. Thank you for a great time and many interesting and constructive discussions.
The last member of our group to stay with us for a little longer is Mr. Tilo Schulz who joined us for a period of 12 weeks for an internship. Mr. Schulz is a student of mechanical engineering at the Technical College (Fachhochschule) Stralsund and will leave us again at the end of November 2014. Also staying for 3 months with us is Ms. Shuang Yu. She is a PhD student of the Biomed-X Centre at Peking University. At the beginning of 2014 Ms. Katja Zocher has joined us to pursue a diploma degree in pharmaceutical sciences. Ms. Zocher is a lisenced pharmacist who was working for several years before she decided to go back to university part time. She is now a student of Prof. Lindequist and for her research studies pulsed electric fields as a means to increase the extraction efficiency of valuable compounds from mushrooms.
Qian ZhangAlready in October 2013, Ms. Qian Zhang has come to the INP on a one year scholarship awarded by the Chinese Academy of Science. Ms. Zhang is a PhD student of Biomedical Engineering of the Academy of Advanced Interdisciplinary Studies at Peking University. In her work with us she found significant synergistic effects in the inactivation of bacteria for the combination of pulsed electric fields and non-thermal. This has now already been described in a short letter published in Applied Physics Letters "Synergistic antibacterial effects of treatments with low temperature plasma jet and pulsed electric fields." (A link to the paper can be found on our publication-page.)
Dr. Camelia Miron Dr. Camelia Miron has joined us on July 1, 2013. Dr. Miron received a Doctor of Engineering from Nagoya University, Japan, in 2011. For her degree in Prof. Takai's laboratory she conducted optical and electrical diagnostics of electrical discharges in liquids. She is now puruing similar studies in our group. In addition to fundamental studies on the developmnet and characteristics of discharges that are instigated with ultrashort high voltage pulses (as short as 1 ns), her interest are in particular possibilities for the modification of surfaces and materials with such discharges.
Finally I would also like to mention two more "visitors" who stayed with us for a little while during the last year. Ms. Johanna Neuber was staying with us for an internship of two months during the summer. She was then an undergraduate student in Electrical Engineering at the University of Texas at Austin. Now she is in pursuit of an MS degree at Old Dominion University. Mr. Andrew Fairbanks was staying with us for about six weeks at around the same time. He was and still is an undergraduate student of Nuclear Engineering at Perdue University, West Lafayette. We wish both of them the best of luck for their academic careers. ("And stay away from canoes!")
Of course we've also kept ourselves busy doing research and presenting our results at conferences. There is just too much to describe it here. Eventually I hope I will be able to present the highlights here. However, in the meantime I encourage you to visit the publication page for the latest updates.

March 23, 2010: I am invited to give a talk on "Streamer Breakdown and Propagation in Water" at the International Workshop on Plasmas with Liquids which is held from March 22-24, 2010 in Ehime, Japan. I will present the considerable research that our group has done on this topic in recent years, both experimentally and theoretically. (For more information, have a look at our publications.)
January 19, 2010: I am happy and proud recipient of the "Shining Star Award:"
The "Shining Star Award" is presented each semester, when warranted to faculty members who demonstrate evidence of helping students succeed academically, professionally, and personally inside and outside the classroom setting.
I would like to thank the students who nominated me and the award committee for this honor.
October 18, 2009: With the help of my colleagues, I could arrange a Workshop on Bioelectrics, which was held in conjunction with this year's IEEE International Conference on Electrical Insulation and Dielectric Phenomena (CEIDP 2009) in Virginia Beach, VA. We could welcome an audience from around the world (United Kingdom, India, Japan, New Zealand and the USA) and introduce them both to fundamental aspects and discuss the newest results of our work. The topic and the talks were enthusiastically received and highly praised by attendees and speakers. The interested response demonstrates once more the growing interest and potential of the subject.
