Summary: The effect of argon and oxygen gases, as well as treatment times, on the properties of modified bamboo fibers using DBD plasma were investigated. Plasma treatment with inert gases generated ions and radicals on the fiber surface. Different spectroscopy and microscopy techniques confirmed changes in chemical composition, crystallinity, and surface roughness. Mechanical properties of the fiber-reinforced epoxy composites showed different trends with different plasma treatments and treatment times.

Summary: This study investigates the formation mechanisms of striations in a single-filament dielectric barrier discharge (DBD) in argon at atmospheric pressure using a time-dependent, spatially two-dimensional fluid-Poisson model. The model is applied to a one-sided DBD arrangement with a 1.5 mm gap and sinusoidal high voltage. The results show that the striations form during the transient glow phase, following the streamer breakdown phase, and are explained by repetitive stepwise ionisation and disturbance of charge carriers' spatial distribution.

Summary: In this study, the hydrophilic properties of PTFE were enhanced using liquid-film DBD at atmospheric pressure, which was compared with air DBD. The results showed that liquid-film DBD generated more active species, had a more stable discharge pattern, and a lower gas temperature compared to air DBD. The surface modification of PTFE by liquid-film DBD did not cause damage and introduced more N- and O-containing functional groups.

Summary: Although low-temperature plasma has been proven to be effective for mineral modification, its application to the pulp system has not been reported. In this study, surface dielectric barrier discharge (SDBD) low-temperature plasma was introduced into the pulp through a bubble generator, and its modification mechanism on arsenopyrite and pyrite was investigated. The results showed that SDBD plasma exhibited excellent selectivity, with much less hydrophilic oxidation products on the surface of plasma-modified pyrite compared to arsenopyrite. The introduction of plasma into the pulp resulted in a longer residence time of the pulp chemistry of arsenopyrite in the stable oxidation region compared to pyrite. Plasma modification significantly enhanced the oxidation degree of the defect area on the surface of arsenopyrite, leading to a decrease in its hydrophobicity and hindering the adsorption of collector and the oxidation of xanthate ions into dixanthogen. Due to its environmentally-friendly property, SDBD plasma modification has a broad application prospect in the flotation separation of polymetallic sulfide ores.

Summary: In this study, the catalyst FeOOH/gamma-Al2O3 was used in a dielectric barrier discharge (DBD) plasma-catalysis system for toluene degradation, and its catalytic performance and mechanism were investigated. The plasma-FeOOH/gamma-Al2O3 system showed significantly improved efficiency, energy yield, and selectivity compared to the plasma-only process. The decrease in ozone concentration in the plasma-FeOOH/gamma-Al2O3 system indicated the important role of ozone catalytic process in toluene degradation. The optimization of process parameters revealed that oxygen content in the background gas was the most significant factor affecting degradation efficiency of toluene.

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: Fluorine resin membranes have great potential for high-performance chemical protective clothing due to their excellent chemical resistance. However, integrating fluorine resins into other materials is challenging due to their low surface energy and poor bondability. In this study, atmospheric pressure dielectric barrier discharge (DBD) plasma was used to modify fluorine resin membranes, improving their surface properties and adhesion strength. The results provide important insights for developing effective strategies to integrate fluorine resin membranes into chemical protective clothing fabrics.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
