The tangential component of electric field along the interface of oil and pressboard causes surface discharge (SD) or surface tracking (different stages of SD is shown in Fig. 1) which can damage the whole or part of insulation structure. Partial Discharge (PD) activity at the interface begins before full surface discharge [1]. In this work, an experimental study was conducted to characterize surface partial discharge pheno mena at synthetic-ester and pressboard interface with moistur e impurities.

The atmospheric-pressure plasma has been proposed as a novel therapeutics for various field of medicine such as anticancer treatment, sterilization, and wound healing. Recent trends of plasma for medical applications focus on the interaction of liquid and reactive species generated by plasma. However, the interactions of liquid and plasma are influenced by surrounding environments such as temperature, humidity. In this work, we suggest the underwater discharge system for medical applications. The system can generate plasma in liquid using capillary electrode having gas channel. Thus, the reactive species generated by plasma interact with liquid without any outside influence and regulate generation of reactive species according to gas type. In order to ascertain the possibility of suggested system for medical applications, we analyze characteristics of underwater discharge and reactive species in water generated by plasma.

Confinement of neutron secondaries (14.1MeV) in deuterium Z-pinch plasmas is of significant scientific and practical interest because it is similar to the confinement of 3.5MeV alpha particles produced in the fusion of deuterium and tritium nuclei. During the final Z-pinch stagnation stage, in very dense target plasmas, the alphas are expected to provide additional heating, and eventually lead to ignition.

An atmospheric pressure inductively coupled plasma (ICP) was obtained by 13.56 MHz rf power. A 3 turn copper coil wrapped around a quartz tube 140 mm length and 16 mm inner diameter. 9 mm tungsten wire was inserted into the tube as an igniter and grounded. As a preliminary experimental study, the optical emission spectroscopy (OES) was used to obtain the electron temperature and density values of the argon plasma. In this study the atmospheric pressure ICP simulation will be carried out by COMSOL at different flow rate of argon and rf power values. The electron temperature and the density of plasma will be compared by the experimental results. Also the spatio-temporal evaluation of these parameters will be given. Rf cycle dependency of plasma parameters will be discussed.

Biomass has been highlighted as a key renewable feedstock to respond to the vital societal need for a step change in the sustainability of energy production which is required to combat climate change. Gasification of biomass wastes represents a major sustainable route to produce syngas (H2 and CO) from a source which is renewable and CO2-neutral. However, one of the major challenges in the gasification process is the contamination of the product syngas with tar which causes major process and syngas end-use problems 1. Non-thermal plasma technology provides an attractive and promising alternative to the conventional approaches for the conversion of tars into clean fuels at a relatively low temperature.1S. Liu, D. Mei, L. Wang, and X. Tu, Chemical Engineering Journal, 307, 2017, pp. 793–802.

Vanadium pentaoxide (V2O5) was widely studied as a functional of electrochromic materials (EC) in the electrochromic devices (ECDs) for the features of good transmittance modulation, good Li+ions intercalation ability. However, it represents low electrical conductivity, poor cycle reversibility. Much scientific research focused on the study of inorganic metal oxide/conducting polymer-based hybrid film due to improved electrochromic properties 1,2.

In the last few decade, carbon nanomaterials such as fullerene, carbon nanotube, and graphite have focused because of its controllable optical, electrical, thermal, and strongly physical properties 1. Therefore, various synthesis methods for obtaining carbon nanoparticle have developed in depth. Among these methods, alternating-current (AC) solution plasma method has great advantage for synthesizing carbon nanoparticles due to having simple, fast, lowtemperature, and high efficiency 2. However, carbon nanoparticles have synthesized via graphite electrode or solution containing carbon atoms. The discharge and nanoparticle properties in solution plasma device with various bubble gas compositions have not yet been studied in detail in terms of bubble gas kinds, bubble speeds, and gas mixture ratios. Accordingly, in this study, we examine to find out influences of bubble gas control on carbon material synthesis and characterization in solution plasma device. The discharge and carbon nanoparticles characteristics were examined relative to the various bubble conditions such as bubble gas kinds, bubble speeds, and gas mixture ratios in solution plasma device. More researches on AC solution plasma physics and properties of carbon nanomaterials will be carried out in detail.

In this study, gas temperature measurements of argon, nitrogen, and air microwave plasma are achieved by the molecular emission spectrometry of the $A^{2} sum ^{+} rightarrow X^{2} prod _{r}$ electronic system of OH radical[1, 2], and the gas temperatures at different microwave power and gas flow rate are explored, the axial temperature distributions of nitrogen and air microwave plasma plume are measured. The experimental results show that the microwave plasma core temperature is higher than 2000 K at different working conditions, even up to over 6000 K in air microwave plasma. At the same working condition, the three kind of microwave plasma gas temperature meet $T_{Ar}, lt T_{N2}, lt T_{Air}$. The gas temperature increases slightly with the increase of microwave power, decreases slightly with the decrease of gas flow overall. The gas temperature of nitrogen and air microwave plasma plume reduces quickly along the axial direction. In order to verify the accuracy of molecular emission spectrometry, the thermocouple is used as a comparison to measure the temperature of the DBD argon plasma. Experiments show that the temperature measurement results of molecular emission spectrometry and thermocouple are very consistent.

The Plasma Liner Experiment-ALPHA (PLX-α) is investigating the merging of supersonic plasma jets into a spherically imploding plasma liner as a driver for use in magneto-inertial fusion (MIF) architectures. 1 The present work is focused on characterizing the merging of six and/or seven plasma jets, converging in a cone of solid angle $0.4 pi $ over a distance of 1.3 meters. Results from high-speed imaging, photodiode arrays, self-emission visible survey spectroscopy, and self-emission visible high-resolution spectroscopy will be presented, yielding measurements of plasma velocity, number density, electron/ ion temperatures, and mean ionization state pre- and post-merge. Anticipated plasma parameter regimes are $mathrm {n}sim 10 ^{15}-10 ^{17}$ cm$^{-3}$, $mathrm {T}sim 1-10$ eV, and $mathrm {v}sim 50$ km/s, with gas species varied among argon, nitrogen, neon, krypton, and xenon. Images and spectra will be compared with synthetic data generated from 3D fronttracking and smooth-particle-hydrodynamic simulations coupled with atomic physics / opacity analysis codes. Results will inform questions of liner-Mach-number and lineruniformity evolution throughout the jet-merging and subsequent liner-convergence process.

This interdisciplinary research project, which focuses on the emerging field of plasma agriculture, seeks to better understand the chemical and physical effects of cold plasma processing on plants and their essential oils. Cold plasma processing has been shown to be a rapid, economical, and pollution-free method to improve plant seed performance and crop yield [1]. Essential oils are aromatic oily liquids extracted from different parts of plants, such as the leaves, flowers, and roots. Among the various beneficial properties of essential oils is their demonstrated antioxidant effect [2], [3] directly applicable to foods that are prone to oxidative consequences such as poor flavor, bad odors, and spoilage. Antioxidants, either synthetic (e.g., butylated hydroxytoluene, BHT) or natural (e.g., Vitamin C), are routinely added to processed foods to inhibit or delay oxidation. Essential oils are examples of natural antioxidants. Although synthetic antioxidants like BHT and BHA (butylated hydroxyanisole) are very effective, they have been shown to be potentially harmful to human health with demonstrated evidence of causing cancer in laboratory animals [3]. As a result, food scientists have been seeking alternative natural compounds as substitute antioxidants, such as essential oils. We have observed a growth effect in our preliminary studies treating basil plants with cold plasmas. We have also observed that plasma treatment increases the antioxidant activity of essential oils. Our preliminary work further revealed a difference in the composition of individual antioxidant components between the plasma-treated and non-plasmatreated basil. Following up on our preliminary research, our present investigation sought to better understand cold plasma's physical and biochemical-molecular effects on basil plants. These latter findings are the focus of this presentation.
