Summary: In this study, a new method of surface modification of Ti6Al7Nb alloy was presented using a stainless steel mask in fluorine plasma, and its influence on selected properties such as chemical composition, topography, and tribological properties was investigated. Different surface characteristics were obtained depending on the etching process parameters. A higher negative bias value led to lower fluorine concentration on the etched surface and higher etching rates. Etching using SF6 gas resulted in higher etching rates compared to CF4 gas etching. The chemical composition of the modified surfaces had a greater impact on tribological properties than topography parameters. The sample modified using CF4 gas showed the lowest wear rate.

Summary: Lithium niobate on insulator is becoming a versatile platform for new photonic integrated devices. Progress has been made to improve the fabrication of optical circuits on a large scale, and the performance has reached remarkable levels. However, the argon etching process is still challenging to optimize due to micro-masking effects and low etch mask selectivity. A workflow is presented to identify the best etching results, and three methods are proposed to achieve redeposition-free lithium niobate etching with good sidewall quality without the need for wet chemistry.

Summary: Tantalum oxide-based coatings have been developed by suspension plasma spraying and their tribological behavior at high temperatures has been evaluated. The coatings exhibit uniform and dense nanostructure with no phase transformation. The friction coefficient of the coatings decreases slightly from 0.9 at 25 degrees C to 0.8 at 300 degrees C, while the wear rate decreases by more than 50%. The decrease in friction and wear at elevated temperatures is attributed to the formation of a smooth continuous layer and a stable transfer film.

Summary: This paper investigates the effects of physical bombardment, chemical reaction etching, and UV radiation on the etching of polymer films by atmospheric pressure plasma jets. The findings show that the absence of oxygen-containing reactive species leads to a rough surface with a low etching rate using a He plasma jet. UV radiation plays a minimal role, mainly modifying the film surface through photooxidation. The synergy of charged particles' bombardment, chemical reaction etching, and UV radiation is necessary for rapid and effective etching. These results provide valuable insights into the etching process of polymer films by atmospheric pressure plasma jets.

Summary: This study proposes a new approach to improve the adhesion of diamond-like carbon (DLC) films on glass. By chemically etching the glass surface to increase the Si-OH content and sequentially depositing SiO2, SiOC, and DLC using magnetron sputtering, a wavy 3D morphology is formed, enhancing the contact area and chemical bonding between the film and glass. The results demonstrate the effectiveness of this method in addressing the issue of weak DLC adhesion on glass surfaces.

Summary: In this study, an atmospheric pressure plasma jet was used to deposit SiOx film on a metal surface, and plasma etching and annealing were applied to improve adhesion strength. The results showed that the adhesion strength of the film after plasma treatment was significantly higher than that of the untreated group, attributed to the increased oxygen content and composition changes in the film. Additionally, the lift-off voltage results in the gas-insulated line system also demonstrated an improvement after the annealing process.

This study examines the etching process of micrometric films of tantalum using SiCl4/Ar plasmas and explores the effects of SiCl4/Ar ratio, plasma power, and chamber pressure on the etching characteristics. The results indicate that increasing SiCl4 flow rate or plasma power leads to higher etching rate, while increasing Ar flow rate and plasma pressure have no significant effect.

Summary: This study reveals that NiMo electrodes used in intermittent water electrolysis easily suffer from oxidation during power interruption, leading to the loss of active sites and conductivity. By understanding the degradation mechanism, a chromium (Cr) coating is successfully applied as a protective layer to inhibit oxygen reduction reaction (ORR) and significantly enhance the stability of NiMo electrodes in intermittent electrolysis. Experimental and Molecular Dynamics (MD) simulations show that the Cr coating acts as a physical barrier for preventing oxygen diffusion while allowing other species to pass through.

Summary: By using atom probe tomography, we investigated the relationship between hydrogen, carbon, and microstructural features in a dual precipitating low carbon martensitic steel. Our findings show that TiC and Cu precipitates act as trapping sites for hydrogen, while dislocations without carbon do not trap hydrogen. The order of trapping effectiveness for deuterium is TiC-decorated dislocations > high energy grain boundaries > low energy grain boundaries.

Summary: Orthopedic implants provide patients with an opportunity to regain lost functionality, but the low bioactivity of Ti-6Al-4V ELI implants and potential adverse effects complicate the recovery process. In this study, Ti-6Al-4V ELI samples were coated with diamond-like carbon (DLC) to improve their biological properties, and the effects were correlated to the bioactivities of the coated and uncoated samples using in vitro studies with osteosarcoma cells. The study found that DLC coating can enhance the surface bioactivity of the material and promote bone cell proliferation and maturity.
