Invited LTP Perspectives: Policy, Opportunities, Challenges
Creating Circular Food Production with Clean Alternatives for Agrochemicals
Nitrogen fertilizers and chemical pesticides have secured our food production making famines a thing of the past in the western world. The use of these agrochemicals however come at a cost. Pesticides are found in our produce and their residues can stay in soil and water for decades. The production of nitrogen fertilizers represents 2% of global energy consumption and contributes to climate change with 3.2% of global greenhouse gas emissions. Plasma technology can offer a clean and sustainable alternative for the use of both agrochemicals. The short-term disinfecting properties of Plasma Activated Water (PAW) can be used to improve crop fitness and crop health, just by spraying PAW on the crop. The residue that remains is a low concentration of nitrate which is a perfect fertilizer that stimulates crop growth. PAW is a liquid fertilizer that can be used in drip irrigation systems.
In 2011, we started the first practical tests in agriculture with PAW with an astonishingly good result. It turned out that PAW could potentially be used as a sustainable alternative for chemical pesticides. With this application in mind, we set up large-scale tests to validate this effect on a practical scale outside the lab, again with promising results. Step by step, we further scaled up the technology, continuing to conduct a large range of testing and research in parallel with close collaboration with customers and end users. Bringing technological agricultural innovations from the lab to a practical environment turned out to be quite a challenge. The technology needs to fit within the existing infrastructure of agricultural companies and crop yields must be secured upfront. Furthermore the business model needs to fit. Without a viable business model, no technical innovation can enter the market, no matter how sustainable it is. In addition to the technology, the integration into existing infrastructure, customer value and the business model, the need for authorization and legislation are often underestimated. A thorough analysis of legislation and regulations is crucial before a new innovation can be brought to the market. Legislation often lags behind technical innovations. Sometimes the innovation simply does not fit within the existing legal frameworks.
With our company we are currently at the point where we are actually entering the market with our plasma nitrogen fixation systems. This transition represents a knowledge center for PAW, the opportunity to start working on other applications, again in close collaboration with end users and customers, and perhaps also with you.

Leaders of the LTP Community: Career Profiles
Prof. Dr. Yi-Kang Pu, From Fusion to Low-Temperature Plasmas
Yi-Kang Pu began his academic education in China as a student at the University of Science and Tech-nology of China in the Department of Radio and Electronics, where he received his bachelor degree in 1982. He then continued his studies in the US and received his PhD from the physics department at the Massachusetts Institute of Technology (MIT) in 1989. His thesis on “Trapped Electron Modes and Anomalous Electron Thermal Energy Transport” was supervised by Prof. Bruno Coppi, one of the pioneers of fusion research. After his PhD, he worked for the Spire Cooperation as a senior plasma physicist on plasma applications until 1994. In the same year, he was appointed professor in the Department of Applied Physics at the Beijing Institute of Technology, bringing him back to China. Five years later, in 1999, he moved to Tsinghua University where he became professor in the Department of Electrical Engineering and in 2002 a professor at the Department of Engineering Physics. This is the position he holds today and where he made Tsinghua University famous in our community. It should not pass unnoted that in 2012 he was also a visiting professor at GREMI at the University of Orleans/France. Further, over the past 15 years he has collaborated intensively with the Faculty of Physics and Astronomy at Ruhr University Bochum/Germany, with countless mutual visits.
Yi-Kang has served on the editorial boards of Journal of Physics D since 2009 and as Editor in Chief of the Applied Plasma Section of Reviews of Modern Plasma Physics since 2016. He has also been on the boards of various international scientific societies and conferences, including the International Plasma Chemistry Society, the International Microplasma Workshop, the International Conference of Ionized Gases, and the Asia Pacific Conference of Plasma Science and Technology, to name only a few. A very important work was certainly the translation of the textbook “Principles of Plasma Discharges and Materials Processing” by Mike Lieberman and Allan Lichtenberg into Chinese, which greatly contributes to the distribution and use of the book within the Chinese community, in particular among students.
While in the early phase of his career Yi-Kang worked in the field of hot fusion plasmas, his focus later shifted to low-temperature plasmas, including diagnostics, modeling and plasma surface interaction. In particular, his very detailed and systematic work on collision-radiative models and emission spectroscopy in noble gases, together with his PhD student Xi-Ming Zhu, made significant progress to the field and has become a standard of today. Other significant work concerns, for example, afterglow plasmas, ionization waves, the role of surface oxidation on secondary electron yield, and discharge evolution during sputtering. In all cases, Yi-Kang has connected experimental findings with modelling in order to extract the underlying basic physics.
Yi-Kang Pu is a talented speaker and he has given invited talks at all major plasma conferences. The community knows him as a very knowledgeable, critical, and gentle person and a true leader of the field. Discussions with Yi-Kang are always inspiring and many colleagues have experienced his outstanding hospitality when visiting Beijing. Prof. Yi-Kang Pu’s scientific talent and open character have made Tsinghua University one of the hotspots of plasma research. By supporting his students well beyond the scientific side of life and his exceptional engagement in the organization of conferences and workshops has contributed significantly to the personal exchange within the community, so vital for the scientific life – something we all miss so much during the present pandemic.

Community Initiatives and Special Issues
Special Issues on New Aspects of Quantum Plasma Physics and Novel Aspects of Dusty Plasma Physics in the Journal Reviews of Modern Plasma Physics
We cordially invite your contribution to the following two special issues of Reviews of Modern Plasma Physics:
New Aspects of Quantum Plasma Physics
The special issue, with Prof. A. A. Mamun as a guest editor, will be a collection of high quality review articles by leading researchers.
The study of the physics of quantum plasmas is currently undergoing vigorous development. The con-stituents of astrophysical compact objects (viz. white dwarfs, neutron stars, black holes, etc.) are degener-ate (quantum) plasmas, which are usually explained by different quantum models and approaches. Quan-tum plasmas also occur in many space environments and laboratory devices.
The aim of this special issue is to provide basic knowledge to understand the properties of different quantum plasma media and the fundamental features of the various types of linear and nonlinear waves propagating in them.
We are expecting submissions by 31 October 2021. More information and submission instructions
Novel Aspects of Dusty Plasma Physics
The special issue, with Profs. A. Sen and Lin I as guest editors, will be a collection of high quality review articles by leading researchers. The aim of this special issue is to provide a basic understanding on various important dusty plasma physics.
We are expecting submissions by 28 February 2022. More information and submission instructions

Research Highlights and Breakthroughs
Remote Generation of a Large Volume Diffuse Plasma
Low temperature plasma jets exhibit large electric fields, the magnitude of which was measured by several investigators to be in the 10 – 30 kV/cm range. When impinging on a dielectric material the plasma jet causes charges to build on the surface of the dielectric and via capacitive coupling, the electric field can be transmitted to the area behind the dielectric barrier. This transmitted field can ignite a new discharge if the dielectric constitutes tubing where a noble gas is flowing, or if the dielectric is the wall of a chamber/enclosure where the gas and its pressure can be controlled. Therefore, using an external plasma jet one can generate a plasma inside a containment chamber that has no electrodes and no electrical power directly applied to it. The ionization wave emitted by the plasma jet hits the external wall of the dielectric chamber and is transferred inside, and under the right conditions (gas, pressure) can ignite a diffuse volumetric plasma that fills the chamber.
The figure shows a schematic of the experimental scheme and a photograph of the diffuse plasma generated in a Pyrex chamber filled with air at 3 Torr. The advantages of this generation method are that the plasma inside the chamber is free of metal contamination (since there are no electrodes) and unlike most low-pressure RF plasma sources (capacitively or inductively coupled), there is no critical requirement for impedance matching since the driving circuitry of the plasma jet is electrically separate/remote from the chamber, which itself has no internal or external hardwired electrical connections.

Co-treatment of Plasma Activated Medium and Oncotherapeutics Agents to Combat Chemotherapy-resistance in Ovarian Cancer Cells
Recently, medical gas plasma technology has emerged as an oncotherapeutic modality through physical and chemical effects. Here, gas plasma directly, indirectly, and through the concomitant modality of plasma activated medium (PAM) with conventional drugs were utilized on A2780 CP and SKOV-3 cells. These studies are relevant to ovarian cancer and granulosa cell (GC) as normal ovarian cells to overcome chemotherapy resistance in ovarian cancer cells. We showed that PAM in comparison to cold atmospheric plasma (CAP) has a high potential and stronger selectivity for the selected cell lines, where the concentration of H2O2, NO2-, and NO3- reactive species and the pH of plasma treated medium plays the main role. Furthermore, the PAM-based treatment is very promising for ovarian cancer treatment compared to the combination of common carboplatin (CAR) and paclitaxel (PTX) chemotherapy treatments. Regarding the molecular mechanisms, PAM alone and concomitantly with carboplatin sensitizes cancer cells to carboplatin and selectively induces mitochondrial‐related intrinsic apoptosis. In essence, PAM treatment is an innovative and emerging technology for the future combination or multimodal ovarian cancer oncotherapy.

Roughening Surfaces During Plasma Atomic Layer Etching of SiO2
Plasma atomic layer etching (ALE) is a two-step cyclic process designed to remove 1 atomic layer of material per cycle. Nearly ideal ALE is etching of Si by Cl2 and Ar plasmas. In the first step using the Cl2 plasma, Cl atoms passivate the top layer of Si atoms, a process that self terminates when the layer is fully passivated. In the second step, the argon plasma with controlled ion energies onto the substrate chemically sputters the passivated layer – a process that self terminates when the passivated layer is removed.
ALE of dielectrics such as SiO2 uses a fluorocarbon plasma for the first step to passivate the surface with nm layer of CFx polymer forming a SiO2CFx complex at the interface. This process does not self-terminate as an arbitrarily thick polymer can be deposited. In the second step, an Ar plasma chemically sputters the SiO2CFx complex which is regenerated by the overlying polymer. Etching proceeds as long as there is polymer fuel. The etch rate is inversely proportional to the polymer thickness as ions need to penetrate through the polymer to deliver activation energy to the interface. A statistical variation in the thickness of the polymer can result in statistical nm-scale variation in the SiO2 removal thereby producing roughness. Residual polymer from a previous chemical sputtering step enables a thicker polymer after the next passivation step, leading to less etching, more residual polymer and more roughness.
Reactor and feature scale simulations of ALE of SiO2 demonstrate this potential for roughening. The ALE process consists of a 2-frequency capacitively coupled plasma (step 1) sustained in Ar/C4F8/O2 for passivation and (step 2) an Ar plasma for chemical sputtering. The figure shows (top) a quasi-steady state ALE process having a passivation period of 5 seconds. For a longer passivation period of 20 s (bottom), chemical sputtering does not removal all of the polymer each step, resulting in eventual roughening of the surface.

Extracting Electron Scattering Cross Sections from Swarm Data Using Deep Neural Networks and Its Uncertainty Quantification
Electron-neutral scattering cross sections are fundamental quantities in simulations of low temperature plasmas used for many technological applications today. From these microscopic cross sections, several macro-scale quantities (called 'swarm' parameters) can be calculated. However, measurements as well as theoretical calculations of cross sections are challenging. Since the 1960s, researchers have attempted to solve the inverse swarm problem of obtaining cross sections from swarm data; but the solutions are not necessarily unique. To address these issues, we examine the use of deep learning models which are trained using the previous determinations of elastic momentum transfer, ionization and excitation cross sections for different gases available on the LXCat website and their corresponding swarm parameters calculated using the BOLSIG+ solver for the numerical solution of the Boltzmann equation for electrons in weakly ionized gases.
We implement artificial neural network (ANN), convolutional neural network (CNN) and densely connected convolutional network (DenseNet) for this investigation. We test the validity of predictions by all these trained networks for a broad range of gas species and we deduce that DenseNet effectively extracts both long and short term features from the swarm data and hence, it predicts cross sections with significantly higher accuracy compared to ANN. Further, we apply Monte Carlo dropout as Bayesian approximation to estimate the probability distribution of the cross sections to determine all plausible solutions of this inverse problem.
