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: This study reports the engineering of thin microporous membranes using microporous organic nanotubes (MONs) derived from covalent organic frameworks through interfacial polymerization. By incorporating a highly porous and interpenetrated MON layer on the membrane, polyamide membranes with Turing structure, enhanced microporosity, and reduced thickness were formed. The modified MON membranes exhibited remarkable water permeability and high retention of boron and phosphorus under alkaline conditions. Molecular simulations showed that the introduction of MONs reduced amine molecule diffusion and increased membrane porosity and water molecule density around the membrane pores. This study provides new insights into creating high-permeability membranes for precise nanofiltration.

Summary: This study investigates the influence of Co-enriched surface zone and its thickness on the microstructure and mechanical properties of TiN/TiC0.6N0.4/alpha-Al2O3 coatings. The results show that the hardness and Young's modulus of the coatings are hardly affected by the Co-enriched surface zone and its thickness, but the zones with higher Co content in the substrate exhibit lower hardness and Young's modulus. Additionally, the Co-enriched surface zone and its thickness have an effect on the thermal crack networks and adhesion of the coatings.

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: Four model plasma coatings were developed for adhesive joints of a metal/elastomer assembly using selected parameters and precursors. The adhesion strength of prepared assemblies is increasing with different functionalized layers, but mostly depends on the precursor type. Thermodynamic adhesion mechanism may prevail with surface energy closer to the elastomer one.

Summary: In this study, a glass composition with P2O5-53SnF(2)-2B(2)O(3) was prepared and characterized under a nitrogen atmosphere. The presence of new P-N and P = N bonds in the glass network was confirmed, and the transition temperature and weight loss of the glass were found to be influenced by the NH4H2PO4 content. This work demonstrates the potential of nitride tin-boron-fluorophosphate glass as a low-temperature sealing material with satisfactory properties.

Summary: Plasma polymer films are typically composed of very short fragments of the precursor molecules, which limits their applicability in cases where longer molecular structures need to be retained. Plasma-assisted vapour thermal deposition (PAVTD) overcomes this limitation by using classical bulk polymers as precursors, allowing for tunable molecular structures. The PLA-like films produced in this study demonstrate the ability of PAVTD to bridge the gap between classical and plasma polymers.

Summary: Research on surface characterization of plasma-treated seeds has advanced significantly in the past decade, with most studies using SEM and contact angle goniometry. However, few studies focus on the chemical modifications to the seed coat post-plasma treatment. This study summarizes the methods used for analyzing plasma-treated seeds and compares the relative advantages and limitations of these surface analysis techniques through experimentation.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
