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: This paper demonstrates the use of plasma-jet printing (PJP) to deposit thermoelectric nanoflakes onto flexible substrates at room temperature, with substantial improvements in material adhesion and flexibility observed. The printed films exhibit electrical conductivity of 2.5 x 10(3) S m(-1) and a power factor of 70 mu W m(-1) K-2 at room temperature. This advancement in plasma jet printing promotes not only the development of energy harvesting but also large-scale flexible electronics and sensors for space and commercial applications.

Summary: A conical-shaped atmospheric pressure plasma jet (CS-APPJ) was developed to overcome the small treatment area limitation of APPJs. Polypropylene samples were treated by CS-APPJ and characterized by SEM, contact angle, FTIR, and XPS. The treatment was observed to occur on both the face directly in contact with the plasma and the opposite face, resulting in different chemical compositions on each side.

Summary: In this study, SiOxCyHz coatings were prepared in capacitively coupled RF glow discharge from a mixture of TMSAc monomer and oxygen. The properties of the coatings and their stability in air and water environments were examined. Increasing oxygen ratio and pulse repetition frequency improved the resistance of the coatings to the atmospheric environment, while organosilicon coatings prepared in CW mode with high oxygen ratios showed significant delamination after immersion in water. Use of PW plasma improved the stability of the coatings under water environment.

Summary: The loss of hydrophobicity of silicone rubber insulators due to contamination accumulation can increase the risk of flashover and threaten the stability of the electrical power system. To solve this problem, a highly efficient and environmentally friendly microwave plasma surface treatment method was developed. The method only requires low-power electricity and ambient air without the use of any chemical agent or rare gas. The treatment can restore the hydrophobicity of heavily contaminated silicone rubber in around 10 seconds, with long-term aging performance under natural transfer.

Summary: Non-thermal plasma surface functionalization of polymeric materials has gained increasing attention in various application fields in recent decades. However, the diversity of chemical reactions occurring between the surface and the active species in plasma can result in non-specific surface functional groups. Achieving controlled surface chemistries can be challenging as it requires optimization of working parameters and comprehensive analysis of plasma-surface interactions.

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: 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.
