Speaker Nomination
For May - October 2025, IOPS speakers can be nominated via the GEC website by anyone from low temperature plasma and collision physics communities until March 20, 2025.
With speakers' consent, presentations are recorded and are made available for on-demand viewing through the GEC IOPS website.
Two types of seminars will be presented:
Types of Seminars
- Research Highlight (20 minutes + questions): This presentation is intended to summarize a recent publication, and is more highly focused on the topic of the publication.
- Tutorial/Review (30-45 minutes + questions): This presentation more broadly addresses a topic, and is more like a traditional departmental seminar.
GEC is happy to organize the International Online Plasma Seminar (IOPS), a non-profit international seminar, in order to engage the GEC community throughout the year. The main purpose of the seminar is to make high quality research results in low temperature plasma science and collisional physics available to our community at no cost and interactively, as well as to foster scientific discussion. The IOPS sessions happen bi-weekly via Zoom. In this way presentations, that are otherwise only accessible at conferences, are available to anybody - including those who cannot attend classical onsite meetings due to travel restrictions, financial challenges, or other reasons. The virtual seminar is particularly relevant during the pandemic due to social distancing and travel restrictions. Moreover, often students cannot afford to attend on-site seminars, and have no access to such presentations. The virtual IOPS at no cost is available to the students and everyone in the GEC community
Following each presentation at the IOPS, questions can be asked by all attendees verbally and the speaker can answer them. Based on the speaker’s written consent, presentations will be recorded and will be made available for on-demand download. If speakers do not agree to do this, the presentations can still be given, but will not be recorded. The IOPS speakers can be nominated by anybody and are selected by the IOPS committee (Julian Schulze, Li Wang, Pankaj Attri, Sandra Quintanilla, Yang-Yang Fu, Jun-Chieh Wang and Quan-Zhi Zhang). Additionally, IOPS collaborates with OLTP (Online Low Temperature Plasma) to organize joint seminars.
IOPS Presentations begin at 1:00 pm UTC on Thursdays.
Online Low Temperature Plasma (OLTP) seminars begin at 1:00 pm UTC on Tuesdays.
For more information, and to request the Zoom link and password, please contact the IOPS Chair Jun-Chieh Wang (wangjj0120@gmail.com), or Co-Chair Quan-Zhi Zhang (qzzhang@dlut.edu.cn).

The International Online Plasma Seminar is sponsored by Hiden Analytical.
