Summary: This paper aims to simulate plasma-solid interaction in real insulating components using first-principle partial differential equations. A filtering method is applied to allow the use of larger time steps in simulating realistic components. The novel theoretical analysis shows that the filter does not affect the accuracy of the method, as supported by significant numerical experiments.

Summary: This study evaluates the effect of cold plasma treatment on corn starch, finding that longer treatment time leads to thicker films formed on the surface of starch granules, thereby improving their hydrophobicity. Changes in rheological properties are observed after only 5 minutes of treatment, with small effects detected at a molecular level. The proposed treatment is an eco-friendly method to obtain hydrophobic corn starch with no structural changes. The paste formation test showed a reduction of 48% of original viscosity for native starch.

Summary: This article presents a dielectric-barrier-discharge-based square unipolar microsecond-pulsed helium atmospheric pressure plasma jet (APPJ). A simplified equivalent circuit model and transferred charge measurement were used to characterize the APPJ. The effects of operational parameters on the performance of the plasma jet and the properties of liquid media treated by the plasma were investigated, and the correlation between plasma characteristics and properties of plasma-treated liquid was discussed.

Summary: This study investigates the self-consistent ambipolar charge kinetics across a negatively biased semiconducting plasma-solid interface. By calculating and visualizing, the study shows that the current-voltage characteristic is influenced by the electron microphysics of the semiconductor, indicating that the perfect absorber model commonly used for plasma-solid interfaces cannot be maintained for semiconducting interfaces.

Summary: Non-thermal plasma technology is a promising solution for decomposing CO (2), and this study proposes a deep neural network (DNN) to describe the discharge characteristics and plasma chemistry of CO (2) pulsed discharge at atmospheric pressure. The DNN is trained using fluid model simulation data and shown to provide accurate results in a fraction of the time compared to traditional simulations. The DNN prediction results indicate the influence of pulse rise rate and plateau duration on discharge current, breakdown voltage, electric field, and product species density. Overall, this study demonstrates the reliability and potential of DNN-based methods in non-thermal plasma applications.

Summary: Navier-Stokes computations were used to study the effects of dielectric barrier discharge (DBD) plasma actuators on flow past a square cylinder. It was found that the effectiveness of flow control by the plasma actuators varied with the location and input power of the actuators in different configurations. The best flow control effect was achieved in the last configuration where vortex shedding and drag were significantly reduced.

Summary: Nanocomposite coatings were fabricated using ethyl lactate and silica nanoparticles through atmospheric-pressure plasma-enhanced chemical vapor deposition, with frequency-shift keying applied to alternate deposition between 1 kHz and 15 kHz voltages. The study revealed that deposition of nanoparticles mainly occurred at 1 kHz, while polymerization of ethyl lactate was predominant at 15 kHz. The nanocomposite coatings showed a higher deposition rate of nanoparticles in FSK mode compared to 1 kHz DBD, with different proportions of Si-O-Si and C-O bonds in the coatings. Additionally, in situ FTIR analysis detected the presence of SiO(2)NPs and the formation of CO2 during the process.

Summary: This study investigates the influence of electron density and electron temperature on the reduction of dielectric constant in SiCOH thin films. The results show that at higher pressure, both the electron density and electron temperature decrease, leading to a decrease in the dielectric constant and refractive index of SiCOH films.
