December 2018: Merry Christmas and a Happy New Year!
Happy Holidays and some time to relax, recharge and contemplate. |
May 14-18, 2018: IFAT 2018
We exhibited our approach to use plasma for the decontamination and disinfection of drinking water and waste water once again at IFAT 2018 in Munich, Germany. IFAT is, according to their own testimonial, world's leading trade fair for water, sewage, waste and raw materials management. Indeed we had many interesting talks, found out about the latest developments and technologies and even got some new ideas. I would like to thank everybody stopping by at our booth for their interest and ask them for a couple of more days of their patience before I will be able to follow up. |
January 2018: Welcome Dr. Hongwei Liu
Dr. Liu has actually already joined us in December 2017 - shortly before Christmas. He is currently an Associate Professor at the Institute of Fluid Physics, China Academy of Engineering Physics, Mianyang, China and will stay with us for a year to further develop pulse generators for different applications. |
December 2017: Merry Christmas!
Happy Holidays and some time to relax, recharge and contemplate. |
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
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):
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. I hope you enjoyed your stay and will visit us again soon. |
May 26, 2017: SFB 1270 - ELAINE awarded
Today the DFG has announced that our SFB-Proposal "ELAINE - Electrically Active Implants" is being funded, starting July 1st. The overall goal of the joint effort is the study of implants that are used with or for electrically stimulation. Of particular interest is the regeneration of bone and cartilige tissue. Our project is focusing on the dielectric spectroscopy of cells, tissues and materials. Knowledge of the dielectric properties of tissues at interfaces with implants is crucial for the understanding of the response to electrical stimuli. Our goal is a comprehensive description of implantation and osseointegration with respect to patient-specific differences and implant properties. |
December 12, 2016: Welcome Dr. Junfeng Rao
It is my pleasure to welcome Dr. Junfeng Rao to the INP Greifswald. Dr. Rao is lecturer at the University of Shanghai for Science and Technology in the Department of Electrical Engineering. He is researching new concepts and topologies for pulsed power electric circuits. His pulse generators can be used for example for water treatment but also solution plasmas. I am happy that he will stay with us for one year and share his expertise with us. |
November 1, 2016: Welcome Mr. Raphael Rataj
After an internship at our institute, Raphael decided to stay with us for the thesis work for his master degree. He is currently studying physics at the University Greifswald and I am looking forward to work with him on the study of the devlopment of plasmas in water for the application of short high voltage pulses. |
September 19, 2016: Bioelectrics 2016
Only last week the Bioelectrics community has met once more for the 13th International Bioelectrics Symposium in Rostock, Germany.

October 1, 2015: Welcome Fukun Shi, MS Eng
I would like to welcome Mr. Fukun Shi to our group. Fukun joined us from the South China Normal University, Guangzhou, China with a Master in Engineering and an undergraduate degree in physics from Sichuan University, Chengdu, China. For the next 4 years he will pursue a PhD-degree in physics at the University of Rostock and INP Greifswald, respectively, funded by the China Scholar Council. In this work he plans to investigate dielectric properties of cells and tissues after exposure to electrical stimuli, i.e. in particular pulsed electric fields. |
October 1, 2015: Welcome M.Eng. Tilo Schulz
Tilo is with us for a while now. He started doing a mandatory internship for his bachelor degree in mechanical engineering and then his bachelor thesis on pressurized spark-gap switches in our laboratory. Although he then decided to do his master degree on a different topic he started working with us again in August 2016. He is now immersed in different projects - many of them involve design and construction of high voltage pulse generators. In the picture below he is shown with one of them. |
October 1, 2015: Welcome Dipl.-Pharm. Katja Zocher
Katja is not actually new to the group or the INP. However, I am happy to welcome her now to the INP as brand new PhD-student in Bioelectrics. Just recently Kajta has successfully finished her diploma in pharmaceutical sciences. For her thesis she has explored the possibility to use pulsed electric field to improve the extraction yields from shiitake mushrooms. For her PhD-research she has now switched to algae and different possible plasma extraction methods. |
September 30, 2015: Awards 2015
Two of our students have been very succesful this year in conference competitions for young researchers or students, respectively. Just recently Anna Steuer has been honored for her presentation at the 1st World Congress on Electroporation which was held in Portoroz, Slovenia, from September 6-10, 2015. The image is showing Anna together with Prof. Damijan Miklavcic who was Chair and organizer of the World Congress. Unfortunately, we don't have a picture of our second awardee, Robert Banaschik who was awarded in the student competition of this year's IEEE International Conference on Plasma Science (ICOPS) that was held in Antalya, Turkey, earlier this year from May 24-28, 2015. Both Anna and Robert - Congratulations to a job well done! |

This prestigeous "International Conference on Future Breakthroughs in Science and Society" is held annually in Berlin, Germany, and gives young scientists an opportunity to present their ideas to a worldwide audience. Jie presented our ideas on the application of nanosecond pulsed electric fields for tumor treatments and received much appreciation and was encouraged to continue. |
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:
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. Already 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 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. |
April 11, 2013: European COST Action TD1208: "Electrical discharges with liquids for future applications"
Researchers from the Leibniz Institute for Plasma Science and Technology have met today with colleagues from 22 countries in Brussels. The gathering was prompted by the start of a new network initiative of the European Union with the goal to coordinate efforts in the area of plasmas interacting with liquids. The investigations promises interesting applications and solutions for urgent problems of our society. As a result have research activities in the area intensified during recent years. The INP Greifswald and in particular the Laboratory for Bioelectrics is also engaged in the basic study and the development of novel technologies. With these effort is the INP now part of the COST-Action "Electrical discharges with liquids for future applications". Stephan Reuter and myself (Juergen Kolb) are 2 of the 4 German members of the mangaging committee. The goal is to bring together European research institutes, universities, and industry for collaborative reseach projects. |
February 1, 2013: Welcome Mr. Robert Banaschik
