Summary: This study significantly improved the dispersion of SiC powders by using ternary modifiers, resulting in a highly stable SiC slurry and successfully preparing high-density SiC green bodies. The application of the novel strategy utilizing modifiers enhanced the electrosteric repulsion between particles, leading to stable dispersion of SiC powders in aqueous media.

Summary: This study examined the microstructures of porous platy-alumina scaffolds freeze-cast at different freezing velocities and platelet sizes. The results showed that the platelet size and freezing velocity influenced the transition between platelet rejection and engulfment by ice lamellae. Based on a morphological parameter, the morphologies were categorized into lamellar, dendritic, or isotropic, and a morphology map was constructed to guide the production of novel porous ceramics.

Summary: Bio-inspired porous HA/BaTiO3 composites fabricated via freeze-casting exhibit the potential to promote bone in-growth. Polarized porous HA/BaTiO3 plays a favorable part in bone regeneration, facilitating bone penetration through the implants. The combination of microstructure osteoconductivity and augmented osteogenic cell behavior induced by polarized porous HA/BaTiO3 surfaces makes them promising scaffolds for bone repair.

Summary: The study aimed to vary the wall thicknesses and pore sizes of inversely printed 3D molded bodies, finding that scaffolds with 500 μm strand spacing exhibited the highest compressive strength, with no significant difference regardless of pore size. Samples with 1000 μm pore size showed a significant dependence on strand width, with those having a 2500 μm wall thickness demonstrating the highest compressive strength. Additionally, good biocompatibility was observed with increasing cell numbers over the experimental period for beta-Tricalciumphosphate (beta-TCP).

Summary: This paper derived a generalized ferrofluid based lubrication equation for variable and strong magnetic fields, and applied it to the study of porous journal bearings. The results showed that the dimensionless load-carrying capacity increases with eccentricity ratio and the effect of magnetic field in the x-direction for a thin layer of the porous region.

Summary: In this study, a new strategy of applying a double-layer coating was established to improve both the mechanical strengths and thermal resistances of porous SiC ceramics. The double-layer coating led to a unique gradient pore structure, resulting in increased flexural strengths and decreased thermal conductivities of the ceramics.

Summary: Biphasic calcium phosphate (BCP) containing b-tricalcium phosphate and manganese (Mn)-substituted hydroxyapatite (HAP) was synthesized for the evaluation of osteogenicity and antibacterial action. Mangiferin (MAN) was incorporated into the BCP scaffolds, and the efficacy of Mn at different concentrations (5% and 10% in HAP) was examined. The incorporation of mangiferin resulted in significantly higher levels of ALP activity, and the scaffolds with 10% Mn-incorporated BCP showed better osteogenicity and higher antibacterial properties.
