Summary: MXenes are promising pseudocapacitive materials with high specific capacitance. This study synthesized two sets of niobium-based solid-solution MXenes and investigated the relationship between their electrochemical properties and the ratio of transition metals in the structure, finding that higher niobium content can improve cycling stability. This research shows that the electrochemical properties of MXenes can be controlled by adjusting the ratio of transition metals in the MXene structure.

Summary: The surface compositions, structural profiles, and valence distributions of niobium and niobium-tin under different processing conditions were investigated. It was found that carbide formation during high-temperature baking determines subsequent oxide formation, which has important implications for ultra-high vacuum baking and nitrogen processing. Additionally, vapor-diffused Nb3Sn contains thick metastable oxides, while electrochemically synthesized Nb3Sn only has a thin oxide layer.

Summary: This study evaluated the effect of doxycycline and dexamethasone doped nanoparticles on osteoblasts proliferation and differentiation when applied on titanium surfaces. The results showed that these nanoparticles promoted osteoblasts differentiation, up-regulated the expression of osteogenic genes, and altered cell morphology. Therefore, using these nanoparticles in regenerative procedures around titanium dental implants could potentially create a favorable osteogenic environment.

Summary: T M1/3MS2 (TM = 3d transition metal, M = Nb, Ta) has recently attracted increasing attention due to its wide variety of fascinating magnetic structures and the chiral arrangement of intercalated TM atoms. The bulk properties of Ni1/3NbS2 and Ni1/3TaS2 were investigated through various techniques. The results show that Ni1/3NbS2 undergoes a phase transition at 84 K, developing an antiferromagnetic helical order, while Ni1/3TaS2 exhibits a simple A-type spin configuration below 158 K. These magnetic structures, combined with lattice chirality and metallicity, offer potential for various interesting transport properties, making Ni1/3NbS2 and Ni1/3TaS2 promising candidates for future studies on antiferromagnetic spintronics.

Summary: In this study, the structure, mechanical properties, and abrasion resistance of two triode-plasma nitrided titanium alloys were investigated. The use of metallic alpha-Ti or 13-TiNb layers pre-coated by physical vapour deposition (PVD) was explored. The results showed that the nitrided samples had increased nitrogen concentration, surface hardness, and surface roughness. However, the use of PVD pre-deposition of nanostructured metallic coatings prior to nitriding reduced surface roughening effects. The microabrasion resistance of Ti-6Al-4V substrates with Ti and TiNb coatings was significantly enhanced after nitriding treatment.

Summary: In this study, a disordered cubic phase of rocksalt-type Ti1-xMgxN was successfully synthesized using the conventional bulk synthesis method. The crystal structure and physical properties of the Ti1-xMgxN solid solution can be tuned by the Mg content, showing a metal-to-semiconductor transition and suppression of the superconducting phase transition. The results demonstrate the feasibility of the simple bulk route for the synthesis of Mg-containing ternary nitrides and the modulation of nitride properties through heterovalent ion substitution.

Summary: By increasing interfacial properties between polyurethane cellular foam matrix and short carbon fibre reinforcement, the mechanical properties of a lightweight composite were improved. Surface modification of carbon fibre to incorporate magnetic properties allowed for alignment within the matrix during manufacturing process. The inclusion of magnetised fibres led to significantly improved mechanical properties in tension, but only slight improvement in compression strength.

Summary: The numerical design of the TiNbTaZrMoSn alloy was conducted before its manufacture to predict its performance, and the experimental results were found to be in good agreement with the predictions. The study highlighted the importance of oxide layer thickness and surface potential in osteogenic activity, while cell adhesion and viability were less affected. The TiNbTaZrMoSn alloy showed slightly lower osteogenic properties compared to c.p. Titanium due to its thinner oxide layer and lower surface potential.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
