Summary: Dielectric barrier discharge (DBD)-biochar sequential batch experimental technology was used to degrade atrazine (ATZ) in soil. DBD treatment increased the hydrophilicity, particle size, and instability of soil particles, leading to the exposure of residual ATZ. Biochar introduction compensated for the shortcomings of sole DBD treatment and enhanced ATZ removal efficiency. Proposed ATZ degradation mechanisms included various reactions, such as dealkylation, dechloro-hydroxylation, and alkylic-oxidation.

Summary: This study investigates the transition mechanism of a dual frequency dielectric barrier discharge (DBD) from alpha to alpha-gamma mode at atmospheric pressure, and finds that the increase in emissions of argon and NH, as well as the particle density, characterize this transition. Additionally, it is observed in experiments that increasing the NH3 concentration leads to a decrease in the LF voltage amplitude required to reach the alpha-gamma mode.

Summary: Antibiotics are widely used and their discharge into the environment poses a constant potential threat to the ecosystem. This study focused on the treatment of wastewater containing levofloxacin and sulfadiazine, two typical antibiotics, using atmospheric-pressure dielectric barrier discharge (DBD). The results showed that the total antibiotics removal efficiency could be improved compared to separate single antibiotic treatment. The role of plasma-induced reactive oxygen/nitrogen species (RONS) was examined, with hydroxyl radicals (OH) playing a major role in levofloxacin degradation and ozone and peroxynitrite also contributing to sulfadiazine degradation. The bio-toxicity evaluation demonstrated the safety of the DBD degradation products for the ecological environment.

Summary: A dielectric barrier discharge (DBD) plasma catalytic system was established for the synergistic degradation of benzohydroxamic acid (BHA) using Er3+-BiOI samples. The results showed that Er3+-BiOI had a microglobular structure assembled by nanosheets and exhibited higher BHA degradation efficiency compared to pure BiOI and single DBD system. The degradation mechanism of BHA in the DBD/4% Er3+-BiOI system was proposed, and the key role of center dot OH, center dot O-2(-), and cavities in the degradation of BHA was demonstrated.

Summary: Dielectric barrier discharges (DBDs) play important roles in analytical applications, being ideal ion sources for atmospheric mass spectrometers or ion mobility spectrometers due to their soft ionization capabilities. Further distinction between full and half-dielectric variants of DBDs has shown different analytical performances, leading to the development of the flexible micro tube plasma (F mu TP) design optimized for efficient soft ionization of molecules under ambient air. Spatiotemporal characterization of DBDs has proven to be a powerful diagnostic for precise identification of relevant discharge mechanisms.

Summary: The thermal conductivity of polymer materials is crucial for high-voltage electrical insulation. To address the issue of insulation failure and damage caused by increased heat accumulation, the addition of fillers with high thermal conductivity is a common solution. However, the interfacial thermal resistance between filler and bulk materials poses a major obstacle. In this study, nanofillers are modified using plasma technology to reduce interfacial thermal resistance. Results showed significant increase in thermal conductivity after plasma modification, with the sample modified by Ar+O2 atmosphere exhibiting a 35% increase in thermal conductivity. These findings have potential implications for the development of high-performance epoxy composites.

Summary: Electric field calculations based on the Poisson equation have been widely used in high voltage and plasma technology. However, the traditional simulation technology often simplifies the complex electric field distribution in practical applications, leading to a large error between simulation and actual measurements. To address this, Physics informed neural networks (PINNs) are introduced as partial differential equation solvers for electric field calculations. This paper discusses and compares 2D and 3D electric field distributions and proposes a method for dividing dielectric distribution based on the sigmoid function. PINNs, combined with data and a physical model, establish a method to solve the inverse problem of relative permittivity.

The longer the processing time, the weaker the characteristic peaks on the surface and the higher the trap density with more traps at lower energy levels.

Summary: A chemical kinetic model was used to investigate the decomposition of tetraethoxysilane (TEOS) in O2/Ar atmospheric pressure dielectric barrier discharge, and the results were compared with gas chromatography and optical emission spectroscopy data. The calculations showed that excited Ar primarily caused carbon-carbon bond cleavage in TEOS in the absence of oxygen. However, in the presence of oxygen, the main decomposition process of TEOS involved the substitution of ethoxy (-OC2H5) by hydroxyl (-OH). The variation of these reactions with oxygen composition could explain the transition of the deposition layer from organic to inorganic. The model and its results provided a theoretical basis for further modeling and regulating the quality of the deposition layer.

Summary: In this work, the formation and diffuse discharge of runaway electrons (RAEs) in atmospheric pressure air were investigated using particle-in-cell/Monte Carlo collision simulation, taking into account the field enhancement effect near the cathode surface micro-protrusion. The results showed that the beam amplitude of RAEs is determined by the field enhancement factor and the initial energy of electrons near the micro-protrusion. RAEs precede low energy electrons and guide the discharge propagation by improving pre-ionization, leading to a transition from filamentary discharge mode to diffuse mode and the formation of a wide streamer with a conical shape.
