Summary: Ti6Al7Nb alloy, treated with nitrogen plasma immersion ion implantation (N-PIII), formed a TiN-containing film on the surface which improved properties such as surface roughness, hydrophilicity, hardness, corrosion resistance, protein adsorption, and cell response. In vivo implantation studies showed that the N-PIII treated implants with higher TiN content had better initial bone-implant contact after two weeks, suggesting enhanced performance of Ti6Al7Nb alloy with N-PIII treatment.

Summary: This study found that immobilizing interleukin 4 (IL4) on plasma immersion ion implantation (PIII)-activated surfaces can modify the osteo-immunoregulatory characteristics of barrier membranes for guided tissue regeneration, leading to pro-osteogenic effects. The IL4-immobilized PIII surfaces polarized macrophages to an M2 phenotype and reduced inflammatory cytokine production. Additionally, co-culture of macrophages and bone marrow-derived mesenchymal stromal cells on IL4-immobilized PIII surfaces enhanced the production of angiogenic and osteogenic factors, and triggered autophagy activation. The findings demonstrate that PIII-assisted IL4 immobilization can create a favorable osteoimmune environment for bone regeneration.

Summary: This study combines conventional plasma nitriding and cathodic cage plasma deposition to enhance the surface properties of AISI-M2 steel. The combination effectively improves surface hardness and creates a favorable hardness gradient towards the core, benefiting load-bearing capacity. Duplex-treated samples exhibit iron nitrides and titanium nitride phases. The wear rate and friction coefficient are significantly reduced, and oxidative wear and adhesive wear mechanisms dominate.

Summary: This study investigates the potential of plasma immersion ion implantation (PIII)-treated silk biomaterials for biomedical applications. The results show that PIII treatment can alter the surface chemistry of silk, increase surface stiffness, and promote cell adhesion. However, PIII treatment does not significantly affect fibrous encapsulation and macrophage response in vivo.

Summary: To overcome the low bactericidal activity and poor osteogenic activity of titanium in dental implants, researchers surface-modify biomedical titanium through the plasma immersion coimplantation of magnesium and copper ions. The best-performing Mg/Cu(8/10)-Ti sample promotes cell proliferation and initial cell adhesion, exhibits high hydrophilicity, outstanding activity against periimplantitis-causing bacteria, and shows good bio-/hemocompatibility. This study concludes that Mg/Cu coimplantation endows the titanium surface with high bacteriostatic activity and biocompatibility, which could pave the way for widespread use of titanium-based dental implants.

Summary: The surface of aluminum-doped ZnO (AZO) films was modified using the oxygen plasma immersion ion implantation method (O-PIII). The modified AZO films showed enhanced work function (WF) based on oxygen plasma (O-ICP) treatment, preserving optical characteristics and improving surface morphology. The reduction of oxygen vacancies was responsible for the increased WF. The WF of the modified AZO films decreased rapidly in air following both O-ICP and O-PIII modification, but the O-PIII treatment had a longer-lasting effect.

Summary: This study investigates the dielectric functions of TiN films implanted with Ag ions and subjected to annealing. The results show that the Ag-implanted films exhibit lower metallicity compared to the as-deposited films, while annealing increases the metallic properties of TiN. The spectroscopic ellipsometry data indicates the presence of additional mechanisms influencing the optical properties of TiN.

Summary: This paper investigates the release of toxic ions from titanium alloy and proposes a method of enhancing the osteogenic and antibacterial effects of titanium nitride film by using silver and calcium ions co-implanted in the film. The results show that the co-implanted samples exhibit improved cell adhesion, cell proliferation, and antibacterial activity. This suggests that the synergy obtained by double ions via co-implantation plays a key role in the osteogenic and antibacterial enhancements.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
