title: Influence of Au ions irradiation on the deuterium permeation behavior in the oxidized Fe-Cr-Al ferritic steel
title: Influence of Au ions irradiation on the deuterium permeation behavior in the oxidized Fe-Cr-Al ferritic steel

description: Our previous study has shown that an effective TPB with α-Al2O3 found could be obtained by oxidization of a Fe-Cr-Al ferritic steel. In this study, irradiation effects on deuterium permeation behavior through oxidized Fe-Cr-Al ferritic steel (OFFS) have been investigated by Au ions irradiation followed by deuterium gas driven permeation (GDP) experiments to obtain and compare the deuterium permeability of irradiated and original OFFS samples. Oxide layer has been characterized by X-ray photoelectron spectroscopy (XPS) experiment. The defects in the oxide layer with and without Au ions irradiation have been characterized by Doppler broadening spectrometry of positron annihilation (DBS-PA) experiments. The deuterium permeation behavior of OFFS changed owing to the Au ions irradiation, which might be attributed to the increased density of vacancy-type defects.

title: Dynamic behaviour of alternating current arc discharge in a multi-arc generator at atmospheric pressure
title: Dynamic behaviour of alternating current arc discharge in a multi-arc generator at atmospheric pressure

description: In this letter, a multi-arc generator with three high-voltage electrodes and a common grounded one was developed for the purpose of obtaining large area and steady arc plasma at atmospheric pressure. Three typical discharge states were found in the multi-arc generator: independent movement of three arc columns, confluence oftwo arc columns, and confluence of three arc columns. The three discharge states cyclically occur on the evolution of the arc discharge and their duration is influenced by the power dissipation and plasma working gas flow rate. With an increase of discharge power and a decrease of the gas flow rate, the duration of multiple arcconfluence increases, which contributes to the suppression of the fluctuation amplitude of each arc. Frequency domain analysis of the arc voltage envelope shows that the frequency of arc fluctuation increases in the multi-arc mode in the multi-arc generator compared to that in the single arc mode.

title: Degradation Kinetics and Shelf Life of N-acetylneuraminic Acid at Different pH Values
title: N-乙酰神经氨酸在不同pH值下的降解动力学和货架期

description: The objective of this study was to investigate the stability and degradation kinetics of N-acetylneuraminic acid (Neu5Ac). The pH of the solution strongly influenced the stability of Neu5Ac, which was more stable at neutral pH and low temperatures. Here, we provide detailed information on the degradation kinetics of Neu5Ac at different pH values (1.0, 2.0, 11.0 and 12.0) and temperatures (60, 70, 80 and 90 ◦C). The study of the degradation of Neu5Ac under strongly acidic conditions (pH 1.0–2.0) is highly pertinent for the hydrolysis of polysialic acid. The degradation kinetics of alkaline deacetylation were also studied. Neu5Ac was highly stable at pH 3.0–10.0, even at high temperature, but the addition of H2O2 greatly reduced its stability at pH 5.0, 7.0 and 9.0. Although Neu5Ac has a number of applications in products of everyday life, there are no reports of rigorous shelf-life studies. This research provides kinetic data that can be used to predict product shelf lives at different temperatures and pH values.

title: Reforming of CH4 and CO2 by Combination of Alternating Current-Driven Nonthermal Arc Plasma and Catalyst

description: An experimental plasma reforming reactor for conversion of CH4–CO2 to synthesis gas (syngas) has been developed, in which the plasma is generated by a nonthermal arc plasma torch with simple and compact structure. The effects of total flux of feed gases and the molar ratio of CH4/CO2 on syngas production, selectivities of H2 and CO, and energy conversion efficiency were investigated. It is proven that this kind of plasma is an effective way to reforming of CO2–CH4 with energy conversion efficiency of 5.25 mmol/kJ and energy efficiency of 81%. Moreover, the heat generated by the plasma can be fully utilized to activate catalyst.

title: Improvement on the plasma performances via application of flowing lithium limiters in EAST tokamak

description: Abstract Three generation of flowing liquid lithium (FLiLi) limiters have been developed and successfully tested in EAST since 2014. It was confirmed that liquid Li could be driven by an innovative invessel DC electromagnetic J × B pump to form a recirculating loop. The FLiLi design was continuously upgraded, resulting in improvement of the liquid Li surface coverage (&gt;80%), elimination of surface erosion, and the increase of heat exhaust capability. Promising results are obtained during FLiLi operations, including a reduction of impurities and recycling to improve plasma confinement, and a mitigation of ELM activity in H-mode plasmas. The FLiLi limiter program has shown basic compatibility with H-mode discharges with auxiliary heating power up to 8.3 MW. These efforts will expand to flowing liquid Li PFC in high heat flux zones, e.g. near the divertor strike point in reactors

title: R&D of a strain monitoring system for the EAST tungsten divertor

description: The tungsten divertor of the Experimental Advanced Superconducting Tokamak (EAST) device operates atvarying temperatures and strong electromagnetic fields during plasma operation. In order to monitor thethermomechanical and electromagnetic responses of the structural components, a strain sensor system has beenproposed to be applied in the EAST device. To develop this technology, two initial experiments on the thermalstrain measurement of a tungsten divertor module of the EAST have been carried out using electrical strain gagesand optical strain sensors. However, some engineering issues were exposed during the experiments. Under thiscondition, all these issues are summarized and discussed this time. Moreover, a comparison between the twotechniques has been made when applied in the tungsten divertor. To make them more suitable for the applicationin the tungsten divertor of the EAST, several activities including a thermomechanical simulation, thewelding technologies for the sensors’ installation and a thermal stability test on the optical strain sensors wereconducted. Based on these progresses, it is expected that the strain monitoring system will be established in theEAST device in the near future.

title: A newly designed actively water-cooled Langmuir probe for tokamak devices

description: Conventional Langmuir probes used in tokamak devices get damaged easily and even melt when exposed to divertor plasma with high thermal and particle loads. Recently, the Institute of Plasma Physics, Chinese Academy of Science, aimed to overcome this issue by designing and manufacturing an uncompensated tungsten/oxygen-free copper (OFC)/CuCrZr-alloy structure-based actively water-cooled Langmuir probe, which showed excellent heat removal capability in finite element analyses (FEA). The heat resistance and antiheat fatigue property of the proposed probe were verified by conducting electron beam high heat flux (HHF) tests. Results show that the maximum temperatures of the probe’s tungsten surface were approximately 445 ○C and 875 ○C under heat loads of 10 and 20 MW/m2 , respectively. The probe successfully passed 600 cycles of 10 and 20 MW/m2 thermal fatigue HHF tests. Moreover, no obvious damages were found on the tungsten surface and W/OFC/CuCrZr joints. FEA and HHF test results proved the reliability of the newly designed uncompensated probe. In view of this progress, it is promising to apply this actively water-cooled probe in tokamak devices for plasma diagnostics

title: Instantaneous hydrogen production from ammonia by non-thermal arc plasma combining with catalyst
title: Instantaneous hydrogen production from ammonia by non-thermal arc plasma combining with catalyst

description: Owing to the storage and transportation problems of hydrogen fuel, exploring new methods of the realtime hydrogen production from ammonia becomes attractive. In this paper, non-thermal arc plasma (NTAP) combining with NiO/Al2O3 catalyst is developed to produce hydrogen from ammonia with high efficiency and large scale. The effects of ammonia gas flow rate and discharge power on the gas temperature, electron density, the hydrogen production rate, and energy efficiency were investigated. Experimental results show that the optical emission spectrum of NTAP working with pure ammonia medium was dominated by the atom spectrum of Hα, Hβ, and molecular spectrum of NH component. Under the optimum experimental condition of plasma discharge, the highest energy efficiency of hydrogen production reached 783.4 L/kW·h at NH3 gas flow rate of 30 SLM. When the catalyst was added, and heated by the NTAP simultaneously, the energy efficiency further increased to 1080.0 L/kW·h.

title: Code for the sheath power dissipation induced by ion cyclotron resonance heating
title: 射频鞘中的鞘功率耗散评估程序

description: In ion cyclotron wave heating, sheath power dissipation is an important form of power loss at the boundary. The analysis of sheath power dissipation in RF sheath is of great significance for improving ion cyclotron wave heating. To solve this problem, a one-dimensional collision free RF sheath program is developed. The program is based on the RF sheath model established by Edelberg and Aydil in 1999 and is written in matlab software. The program can be applied to a wide range of RF frequencies and the case of ions containing multiple components. However, if the disturbance current exceeds 3500A, attention should be paid to the instability caused by the time step. Then the sheath power dissipation is calculated according to the formula proposed by Bures. The results of this program support published articles [An, Ou, and Men, Plasma Sci. Technol. 22 (2020) 065103]
