Summary: This paper reviewed the cellular activity on titanium samples exposed to Plasma of Argon (PoA) treatment. The results showed potential effects of PoA in promoting cell adhesion and protein adsorption, but the duration of this effect remains unclear. However, the overall quality of the analyzed studies was poor, and only one in vivo study was conducted. Further research is needed to demonstrate the long-term efficacy of this treatment and support its use in clinical practice.

Summary: This study evaluated the mechanical behavior of superficially modified porous titanium dental implants fabricated by two different routes and discussed the influence of porosity and surface roughness on the stiffness and yield strength of implants. The results showed that macro-pores can localize stress and act as a barrier to micro-crack propagation, while higher rugosity was observed for implants obtained with spacer particles. Superficial modifications, such as using bioglass 1393 coating and chemical etching, were effective in improving the adhesion and roughness of implant surfaces.

Summary: Biocompatible and bio-active coatings on titanium surfaces can enhance osseointegration. This work presents a Gelatin-CaPO4 (Gel-CaP) composite coating that improves osseointegration through chemical binding. The Gel-CaP coating exhibits nanometer range thickness, improved elastic modulus, good wettability, and nanometric roughness. MC3T3 cells show excellent cell proliferation and adhesion on the Gel-CaP coating, indicating its unique osteogenic ability. Overall, this work offers a new perspective on functional, bioactive titanium coatings and Gel-CaP composites as promising candidates for bone regeneration.

Summary: Extracting osmotic energy through nanoporous membranes is an efficient way to harvest renewable and sustainable energy using the salinity gradient between seawater and river water. A lamellar-structured membrane made of nanoporous Ti3C2Tx MXene sheets is reported in this study, showing simultaneous enhancement in permeability and ion selectivity. The constructed internal nanopores lower the energy barrier for ion passage, thereby boosting preferential ion diffusion across the membrane. This membrane design strategy using nanoporous two-dimensional sheets provides a promising approach for ion exchange, osmotic energy extraction, and other nanofluidic applications.

Summary: The study assessed long-term survivorship and functional and radiographic outcomes of the Zimmer Modular Revision hip (ZMR) system. Results showed high survivorship rates at 15 years for both PCM and TM cohorts. Aseptic loosening was the most common cause of revision surgery. Previous concerns regarding modular junctional weakness seem to have been addressed satisfactorily.

Summary: In this study, pure Ti was anodically oxidized using 1M H3PO4 + 2-10 pct HF electrolytes to form surface layers containing TiO2 and Ti(HPO4)(2). The resulting surfaces showed good bioadhesion properties and support for the osseointegration process. These findings suggest potential applications for hard tissue implants.

Summary: This study investigates the modification of hydroxyapatite coating structure by changing the coating process and post-heat treatment. The novel Aerosol Cold Spraying system is used for the deposition of coatings, and Spark Plasma Sintering and Pressureless Sintering are employed for post-processing. The results show that homogenous buildup of hydroxyapatite is achieved using Aerosol Cold Spraying, but there are various pores and microcracks in the sprayed coatings. The thermal post-processing improves the adhesion bond strength and crystal size of the coatings.

Summary: The goal of this study was to develop poreless titanium alloys with nanocrystalline structure. The effects of Ta, Mg, and Zn content on the properties of Ti alloys were investigated. Nanocrystalline powders of TixTayMg and TixTayZn were prepared using mechanical alloying, followed by hot-pressing to consolidate the powders. The alloys with Mg showed improved mechanical properties and a more hydrophobic surface, while all new alloys exhibited non-toxic properties. The Ti40Ta5Mg alloy had the most promising properties for biomedical applications, with a high Ti-beta phase content, low porosity, low Young modulus and low surface free energy.
