Summary: PEO coatings were developed on MgZnxCay alloys for biomedical applications using different treatment times and a novel transparent electrolyte containing Ca, P, Si and F. The study found that Zn-rich intermetallics favor the formation of large voids in the coatings, and Ca, P, F, and Si are successfully incorporated into the coatings. The coatings consist of crystalline phases and amorphous material. Corrosion of the bare substrates can be accelerated by amino acids and organic components in the α-MEM solution, but they have no significant influence on the corrosion resistance of coated specimens. Furthermore, Zn-rich intermetallic particles in the undercoating crevice induce a more aggressive corrosive environment and enhanced micro-galvanic couple effect, leading to faster degradation of the coated alloys.

Summary: In this research, a self-assembled amorphous calcium carbonate (ACC)@curcumin (Cur) loaded polymethyltrimethoxysilane (PMTMS) coating on micro-arc oxidation (MAO) coated magnesium (Mg) alloy was proposed to overcome the issues of rapid corrosion and bacterial infection in using biodegradable Mg alloy for biomedical materials. The coating exhibited favorable corrosion resistance, dual antibacterial ability, and good biocompatibility. Cur was employed as an antibacterial agent and photosensitizer for photothermal therapy. The core of ACC significantly improved the loading of Cur and the deposition of hydroxyapatite corrosion products during degradation, thus enhancing the long-term corrosion resistance and antibacterial activity of Mg alloys.

Summary: 316L stainless steel is commonly used in biomedical implant applications due to its strength, durability, and cost-effectiveness. However, prolonged exposure to the body's physiological environment can lead to corrosion and wear. This study comprehensively investigates the corrosion and wear performance of TiNbTaZr/Cr-Mo PVD coatings on 316L stainless steel for improved biomedical applications. The coatings exhibit nano-sized grain structures, higher hardness than uncoated samples, improved hydrophilicity, and superior corrosion resistance and reduced wear under simulated body fluid conditions.

Summary: Various biomaterials such as 316L steel, magnesium-alloy, Ni-Ti, titanium-alloy, and cobalt-alloy are commonly used in biomedical applications due to their excellent mechanical characteristics and corrosion resistance, although they may sometimes be incompatible with the body. Surface coating is necessary to mitigate the release of contaminants, with hydroxyapatite powder (HAp) widely used for forming biocompatible coatings. The HAp added-EDM process has been shown to significantly improve coating properties, corrosion resistance, and biofunctions of biomaterials, highlighting the importance of these factors for biomaterial performance.

Summary: A new approach using conjugated microporous polymers (CMPs) to coat silica microparticles for removing organic compounds, especially pharmaceuticals, from waterbodies is presented. The CMPs were generated with different monomers and coupled to 1,3,5-triethynylbenzene (TEB) via Sonogashira coupling. The resulting coatings were adjustable in polarity and functionality, and had increased accessible surface area compared to bulk materials. The aniline-based CMP showed the highest adsorption capacity for the model drug diclofenac.

Summary: In this study, a NiCrAlTi nanocrystalline coating was prepared by magnetron sputtering, with a moderate amount of oxygen successfully doped in the coating. The introduction of oxygen led to the formation of in situ nanoprecipitates at the interface, which enhanced energy dissipation at the crack tip and deflected propagation of cracks in the coating. The NiCrAlTi(O) coating exhibited a high H3/E2 ratio and a low cavitation erosion rate compared with the conventional NiCrAlTi coating.

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.
