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: Titanium alloys, particularly TMZF, have excellent mechanical properties and biocompatibility. However, their poor osteointegration limits their orthopedic applications. In this study, a bioactive coating was dip-coated onto the TMZF substrate surface using the layer-by-layer method. The coated samples showed a uniform and adherent bioactive coating, resulting from changes in the substrate surface morphology and chemical composition. Immersion in SBF solution demonstrated excellent bioactivity, with apatite-related deposits observed after 24 hours. A model of physical and chemical anchorage of the bioactive glass coating on TMZF was proposed.

Summary: The phase evolution of alloys and atomic diffusion are closely related. However, the influence of reactive diffusion on phase formation in high-entropy alloys (HEAs) is still not clear. This study investigates the phase evolution of a multicomponent CoCrFeNi/Al diffusion couple and reveals the combined effects of enthalpy and entropy on phase formation in HEAs at elevated temperatures. Surface modification of HEAs can be achieved through film deposition and annealing processes.

Summary: In this study, CoCrFeMnNi high-entropy alloys with a surface gradient nanostructure were produced using industrial shot blasting, which significantly improved their mechanical properties. The severely plastically deformed surface layer had a multi-scale hierarchical structure and increased in depth with shot-blasting time. The microhardness and tensile strength of the alloy were significantly higher after shot-blasting. The improved strain hardening and prevention of early necking in the gradient-nanostructured surface layer contributed to its high toughness.

Summary: The effects of severe plastic deformation (SPD) by means of high-pressure torsion (HPT) on Fe73.9Cu1Nb3Si15.5B6.6 and Fe81.2Co4Si0.5B9.5P4Cu0.8 iron-based metallic glasses were compared. HPT processing extended the consolidation and deformation ranges for Fe73.9Cu1Nb3Si15.5B6.6, and achieved consolidation and deformation with minimum cracks for Fe81.2Co4Si0.5B9.5P4Cu0.8 for the first time. Various analyses revealed that Fe81.2Co4Si0.5B9.5P4Cu0.8 exhibited HPT-induced crystallization phenomena, while Fe73.9Cu1Nb3Si15.5B6.6 did not crystallize even at high HPT-deformation degrees.

Summary: The shock-induced dynamic mechanical behavior and spallation failure of Ni-based single crystal superalloys are studied using non-equilibrium molecular dynamic simulations. Two modes of classical spallation and micro-spallation are observed during the spallation failure. The deformation mechanism is dominated by slip and drag of dislocations at low shock velocities, while complex phase transitions from FCC to BCC or disordered structures occur at higher velocities, leading to a decrease in spallation strength. The presence of voids significantly lowers the spallation strength, and the reduction in strength is proportional to the radius of the voids.

Summary: Selective laser melting (SLM) was utilized to produce CuZrAl metallic glass (MG) scaffolds with combined lattice structures of body-centered cubic and face-centered cubic (F2BCC), and the effects of lattice structures on mechanical behavior were investigated. The results revealed that curved struts remarkably enhanced compressive ductility by 122% and energy absorption by 106%. The presence of curved struts effectively prevented catastrophic shear fracture and delayed fracture occurrence due to the release of strain concentrations. This study demonstrates the potential of improving the ductility and toughness of SLM MG components through appropriate lattice structure design.

Summary: In this study, TiAl and Cr3C2 particles were added to a CrMnFeCoNi alloy to improve its processibility and mechanical properties. The addition of TiAl particles resulted in the formation of cracks, but the further addition of Cr3C2 particles helped suppress hot cracking. The presence of long-range ordered domains and precipitates contributed to the improved strength of the dual-particle containing alloy.

Summary: This study focuses on the synthesis and properties comparison of a novel organic composite nanofiber material consisting of styrene-butadiene-styrene (SBS) copolymer blended with polystyrene (PStyr) and carbon nanotubes (CNTs). The addition of CNTs retards the crystallization process and decreases the absorbance of both SBS/PStyr and PStyr/PBu in Fourier transform infrared spectroscopy. The interaction of CNTs with the blend is limited in samples with SBS, as observed in Raman spectroscopy.

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.
