Data-driven science and technology offer transformative tools and methods to science. This review article highlights the latest development and progress in the interdisciplinary field of data-driven ...plasma science (DDPS), i.e., plasma science whose progress is driven strongly by data and data analyses. Plasma is considered to be the most ubiquitous form of observable matter in the universe. Data associated with plasmas can, therefore, cover extremely large spatial and temporal scales, and often provide essential information for other scientific disciplines. Thanks to the latest technological developments, plasma experiments, observations, and computation now produce a large amount of data that can no longer be analyzed or interpreted manually. This trend now necessitates a highly sophisticated use of high-performance computers for data analyses, making artificial intelligence and machine learning vital components of DDPS. This article contains seven primary sections, in addition to the introduction and summary. Following an overview of fundamental data-driven science, five other sections cover widely studied topics of plasma science and technologies, i.e., basic plasma physics and laboratory experiments, magnetic confinement fusion, inertial confinement fusion and high-energy-density physics, space and astronomical plasmas, and plasma technologies for industrial and other applications. The final Section before the summary discusses plasma-related databases that could significantly contribute to DDPS. Each primary Section starts with a brief introduction to the topic, discusses the state-of-the-art developments in the use of data and/or data-scientific approaches, and presents the summary and outlook. Despite the recent impressive signs of progress, the DDPS is still in its infancy. This article attempts to offer a broad perspective on the development of this field and identify where further innovations are required.
In this article, the optimization of spatial parameters of a 2.45-GHz atmospheric pressure plasma jet (APPJ) at different operational parameters has been done. For this purpose, simulations and ...experiments have been carried out to investigate the spatial dimensions of the microwave cold plasma jet generated from the device. To achieve this, the plasma discharge behavior and jet formation have been studied at different working gas flow rates and input microwave power. The 3-D simulations have been carried out by using the plasma module and electromagnetic wave module of COMSOL Multiphysics v. 5.5. Experimental validation was achieved and simulated spatial dimensions of plasma jet showed good correspondence with the experimental results. Simulated variations of jet length and diameter with gas flow rate and applied power matched closely with experimental results. Intrinsic plasma parameters, such as electron temperature (<inline-formula> <tex-math notation="LaTeX">T_{e})</tex-math> </inline-formula> and number density (<inline-formula> <tex-math notation="LaTeX">n_{e})</tex-math> </inline-formula>, were also obtained with the simulation model and compared with experimental findings based on optical emission spectroscopy (OES) results and <inline-formula> <tex-math notation="LaTeX">T_{e}</tex-math> </inline-formula> values matched well in both cases.
Developing rapid and diverse microbial mutation tool is of importance to strain modification. In this review, a new mutagenesis method for microbial mutation breeding using the radio-frequency ...atmospheric-pressure glow discharge (RF APGD) plasma jets is summarized. Based on the experimental study, the helium RF APGD plasma jet has been found to be able to change the DNA sequences significantly, indicating that the RF APGD plasma jet would be a powerful tool for the microbial mutagenesis with its outstanding features, such as the low and controllable gas temperatures, abundant chemically reactive species, rapid mutation, high operation flexibility, etc. Then, with the RF APGD plasma generator as the core component, a mutation machine named as atmospheric and room temperature plasma (ARTP) mutation system has been developed and successfully employed for the mutation breeding of more than 40 kinds of microorganisms including bacteria, fungi, and microalgae. Finally, the prospect of the ARTP mutagenesis is discussed.
Representatives from many industrial sectors are searching for more economic and ecologically sound technologies to meet regulatory and competitive pressures. Currently, the majority of industrial ...plasma processing is done with glow discharges at pressures below 10 torr. This tends to limit such applications to high-value items, as a result of the high capital cost of vacuum systems and the production constraints of batch processing. It has long been recognized that glow discharges would play a much larger industrial role if they could be generated at one atmosphere and in ambient air. A promising platform technology for plasma processing across many industrial sectors is the one atmosphere uniform glow discharge plasma (OAUGDP), a nonthermal normal glow discharge that operates in air (and other gases) at room temperature and atmospheric pressure. It generates active species useful for the sterilization, decontamination, and surface energy enhancement of films, fabrics, air filters, metals, and 3-D workpieces. This paper will survey exploratory research and development at the University of Tennessee's Plasma Sciences Laboratory on eight potential industrial applications of the OAUGDP that can be conducted at one atmosphere and at room temperature with air as the working gas
