Summary: This study investigates self-deformation of an atmospheric pressure diffuse discharge initiated between a needle anode and a water cathode, showing a morphological transition from a cone to asymmetric shapes over time. The pH value and electrical conductivity of the water cathode vary during this process. The electrical measurements indicate that the different discharge morphologies may have different formation mechanisms, with conical discharge showing time-invariant behavior while the other two discharges exhibit periodic pulsing. Visual results show that the different discharge morphologies belong to a glow discharge regime, with each type consisting of stationary or moving micro-discharges.

Summary: The effects of plasma treatment time on the gas permeation and pervaporation dehydration properties of organosilica membranes were investigated. The study found that increasing plasma modification time resulted in a decrease in pore size, leading to an increased He/N2 permeance ratio. The H2O/EtOH permeance ratio also increased from about 20 to over 1000 as the plasma modification time increased due to changes in pore structure and water adsorption properties.

Summary: In this study, novel atmospheric pressure microplasma systems were investigated for the determination of Ga and In by optical emission spectrometry (OES), with optimized working parameters and the addition of low molecular weight organic compounds (LMWOCs) into the solution. The impact of concomitant ions on the signals intensity of Ga and In was also studied, showing the resistance to matrix effects. The detection limits obtained under optimized conditions were comparable to those obtained by large-scale instrumentation, confirming the accuracy and reliability of the developed FLC-APGD-OES method.

Summary: This article investigates the discharge characteristics of an atmospheric pressure surface dielectric barrier discharge (SDBD) generated in helium and its ability to produce amine functionalised polymer coatings for cell therapy applications. The experimental results show that the plasma device is capable of generating glow-like discharge structures that are stable over the electrode area, and high electric fields around the mesh electrode. The surface characterisation of the coating revealed rich amine functionality, potentially suitable for cell adhesion and growth.

Summary: The study investigates the dynamic evolution of plasma optical emission from an array of surface micro-discharges, revealing the interaction between co- and counter-propagating streamers resulting in new streamer fronts with altered velocities and intensities. Additionally, the emergence of secondary streamers is attributed to surface charges accumulated during a prior half cycle and turbulence fluctuations dominated by electrohydrodynamic force.

Summary: In this study, a cold atmospheric pressure plasma jet was used to modify the surface of glass fibers with tetraethyl orthosilicate as a precursor. SiOx nanoparticles were polymerized on the fiber surfaces to enhance the interfacial bonding forces of glass fiber reinforced polypropylene (GFRP) composites. The effect of nozzle-to-fiber distance (D) and treatment time (T) on the interfacial bonding behavior of GFRP composites was investigated. The optimal parameters were found to be D = 17 mm and T = 12 s, leading to a 30.79% increase in interlaminar shear strength compared to the control group. Further analysis revealed that plasma treatment increased surface roughness, surface energy, and the presence of oxygen-containing functional groups, contributing to the improvement in interlaminar shear strength.

Summary: A nonthermal atmospheric plasma reactor was used to sterilize polymer surfaces in a biological medium. The study analyzed the behavior of a dielectric barrier discharge (DBD) and its parameters, and found that increasing voltage or frequency increased ionization levels and sterilization efficiency. The study also identified the need for short gap width and oxygen admixture for effective bio-decontamination. These findings can benefit plasma-based pollutant degradation devices.

Summary: This study examines the statistical properties of asymmetric surface dielectric barrier discharges (SDBD) and finds that the bursts during backward strokes carry positive charge and current, while bursts during forward strokes carry negative charge and current. The analysis suggests that power injection can be tailored for specific plasma applications, and discharge spatial correlation patterns were determined from optical emission measurements.

After a certain period of plasma irradiation, the hydrophobic polystyrene surface changed to hydrophilic, and the wettability of the surface increased with time. The evaluation of surface properties was done through measuring water contact angle and Fourier transform infrared spectroscopy, and the relationship between plasma parameters and surface modification of the polymer was discussed.
