General Interest Announcements
The ILTPC is maintaining a list of LTP conferences (view-only). With many meetings being canceled and rescheduled, we thought this would be useful for minimizing conflicts and planning future trips. The data may not be 100% accurate, so please let us know of changes in conference scheduling.

Survey on Research Data Management in Low Temperature Plasmas
A survey on research data management in low-temperature plasma physics is being conducted with the goal of developing a FAIR system for LTP data Findability, Accessibility, Interoperability and Re-usability. The survey is being conducted in the framework of the joint project Quality Assurance and Linking of Research Data in Plasma Technology (QPTD) at the Leibniz Institute for Plasma Science and Technology (INP) together with FIZ Karlsruhe -Leibniz-Institut für Informationsinfrastruktur GmbH, and Hamburg University of Applied Sciences. The survey aims to evaluate the status quo regarding research data management in the field of low-temperature plasma science. The survey also will identify the relevant experimental and computational methods that will be used as a first reference for the design and testing of quality criteria and (meta)data models for research data management.

Joint US National Science Foundation (NSF) and German Deutsche Forschungsgemeinschaft (German Research Foundation, DFG) Program in Electrosynthesis and Electrocatalysis
A joint research opportunity involving the NSF and DFG is available for research in electrosynthesis and electrocatalysis, including plasma processes. From the announcement:
“We are particularly interested in novel and fundamental electrochemical reactions and studies addressing transformations in organic and polymer synthesis, water splitting (hydrogen/oxygen evolution), and nitrogen reduction (ammonia production). Relevant activities include, but are not limited to, mechanistic studies; catalyst design, synthesis, and characterization; computational modeling, theory, and simulation; and experimental tool development. For fundamental engineering science projects, we are interested in studies involving reaction engineering, reactor system design, and component or device scale studies as examples that provide fundamental knowledge supporting scale-up of systems. In addition, fundamental engineering science projects involving alternative (to thermal) activation mechanisms such as microwaves (e.g. microwave assisted catalysis) and low temperature plasmas (e.g. plasma-assisted catalysis) are welcomed.”
At-Home STEM Projects for Children
The NSF Center Connecting the Plasma Universe to Plasma Technology in Alabama (CPU2AL) is presenting a new STEM outreach opportunity, specifically targeted at school-aged children.
CPU2AL seeks to understand, predict, and control plasma processes and interactions in low-temperature plasma (LTP) environments. This knowledge can be used to develop new technologies for aerospace, manufacturing, medicine, agriculture, and food safety.
As a part of its Workforce Development program, CPU2AL seeks to inspire K-12 students through hands-on learning opportunities. Due to the current health risk, we have opted not to host our annual in-person Science and Technology Open House. Instead, starting Monday, June 22, our team will send weekly STEM projects that have been reviewed by CPU2AL researchers for school level appropriateness. We normally focus our Workforce Development efforts on Alabama. However, this email list is open to anyone who is interested. Feel free to share this information with your colleagues, family, and friends!

Research Highlights and Breakthroughs
Speeding the Solution of Complex Systems of Equations for Plasma Transport
The implicit discretization of plasma transport equations results in coupled linear(ized) equations for the unknowns (particle densities, energy densities, …). Such equations can be written in the form Ax=b, where the “solution vector” x represents the unknowns and b the source terms. The “system matrix” A depends on grid properties, the transport coefficients and the flow field. For a three-dimensional simulation with 100 grid points in each directions, the matrix has a million rows and columns, but of its 1012 elements, only a small fraction is non-zero (for example, 7 million).
Efficient methods for solving for the unknowns x use this sparsity of the system matrix and are iterative in nature, such that the present field values can be used as an initial guess when a time step is effectuated. This yields a 2-1600x speedup in the solve step of a recent simulation.
Chris Schoutrop of the PLASIMO team at TU/e, in collaboration with the eScience Center Amsterdam and Plasma Matters B.V. have recently implemented the iterative solvers BiCGStab(L) and IDRStab for the C++ matrix-vector library Eigen. Our tests demonstrate that in particular IDRStab shows improvements in robustness compared to BiCGStab for problems that are representative for plasma simulation. The code has been made available under an open source license.
The Plasma Physics of Entering Planetary Atmospheres
In 1995, the Galileo mission to Jupiter launched a probe that descended from Mach 50 to Mach 1 during its entry, generating enough heat to cause plasma reactions on the surface. The data on the probe’s heatshield burning differed from the effects predicted in fluid dynamics models.
Researchers of the group N-PRiME (N-Plasmas Reactive: Modelling and Simulation), with Instituto de Plasmas e Fusão Nuclar (IPFN) of Instituto Superior Técnico (IST), Lisbon, Portugal, in collaboration the University of Illinois at Urbana-Champaign, IL, USA, examined what might have caused such a discrepancy, applying new computational techniques to fluid radiative dynamic models and using data transmitted from Galileo's 30-second entry. We recalculated features of the hydrogen-helium mixture the probe passed through, such as viscosity, thermal conductivity and mass diffusion, and found that the Wilke/Blottner/Eucken transport model fails to accurately predict the interactions between hydrogen and helium molecules. The work helps improve future spacecraft design, including upcoming projects to explore Neptune.
Treating Bone Cancer with Plasmas
The recent paper of M. Mateu-Sanz et al. Cold Plasma-Treated Ringer's Saline: A Weapon to Target Osteosarcoma, Cancers 12, p. 227 (2020), focuses in obtaining mechanistic insights on the action of plasma-activated Ringer’s saline for bone cancer therapy in 2D cultures and also in tumor organotypic cultures.
The paper is included in the research of the ERC pro-ject APACHE “Atmospheric Pressure Plasma Meets Biomaterials for Bone Cancer Healing”. To date, seven papers have been published in Q1 peer-reviewed journals that can be retrieved at the project website.

Killing Virus in Aerosols Using Plasmas
Airborne infections are growing global concern causing severe economic and sociopolitical disruption, which has been recently illustrated by the dramatic spread of COVID-19. Low tempera-ture plasma can be a novel and highly effective decontamina-tion technology. Recently, our team reported on the successful inactivation of aerosolized porcine reproductive and respiratory syndrome (PRRS) virus using a volume DBD reactor embedded in a small-scale single pass wind tunnel. The aerosolized virus particles were sampled both upstream and downstream of the plasma reactor, where the virus came in direct contact with the highly reactive short-lived species, such as OH and single oxy-gen, for a short particle residence time of 15 milliseconds. The infectivity test showed the plasma induced a reduction of 3.5-log in the viable virus titer. Independent testing of the genome concentration confirmed the PRRS virus inactivation by the plasma, with very small amount of virus lost in the reactor. The results of this study show the potential of plasma technology to highly reduce the transmission of airborne infections when im-plemented in indoor environments and particularly confined spaces like aircraft.
US National Academies Plasma 2020 Decadal Assessment Released
The US National Academies of Science, Engineering and Medicine (NASEM) have just release the (prepublication) version of the Decadal Assessment of Plasma Science – Plasma 2020. The Decadal Assessment, titled Plasma Science: Enabling Technology, Sustainability, Security and Exploration, broadly addresses all fields of plasma science. Accomplishments of the past decade are reviewed and research opportunities for the coming decade are discussed. The Finding and Recommendations are intended to inform US policy makers, however the technical findings and science challenges should be informative for the entire international community.
A free PDF of the prepublication version of the report is now available.
