Summary: Composite scaffolds made of boron-doped hydroxyapatite and baghdadite were successfully prepared. The incorporation of baghdadite increased scaffold porosity, surface area, and micropore volumes. The composite scaffolds exhibited higher degradation rates, enhanced cell proliferation, and greater osteogenic differentiation compared to the boron-doped hydroxyapatite scaffolds. Despite being slightly weaker, the compressive strengths of the composite scaffolds were higher than other baghdadite-based composite scaffolds reported in the literature. Overall, the novel composite scaffolds combined the advantages of both components and advanced the development of ideal scaffolds for bone tissue engineering.

Summary: This study investigates the moisture adsorption performance of composite porous membranes in the absence of pressure driving force. PVDF/PVA/CaCl2 membranes with outstanding hygroscopic properties were prepared, exhibiting a highest initial moisture adsorption rate of 0.053 g,g(-1).min(-1) and moisture adsorption capacity of 2.36 g.g(-1). The core-shell structure of the membranes provided excellent strength and stability. This work offers a new concept for designing nonpressure-driven dehumidified membrane materials.

Summary: Alginate aerogel particles were successfully coated with a copovidone and hydroxypropyl cellulose based polymer in a Wurster fluidized bed. The results indicate that the pores of aerogels were not damaged during the process. Changing bed temperature led to significant changes in coating thickness whereas both bed temperature and atomizing pressure affected coating layer surface morphology. The smoothest coating layer surface and the highest coating efficiency were achieved at 50 degrees C with 1.7 bar atomizing pressure.

Summary: Developing NIR-induced self-healing composite coatings with high transparency is a challenging issue. This study presents a new type of NIR-induced self-healing composite coating, ACWx, which is prepared using acrylate resin system and surface activated W18O49 nanowires (mW18O49). The loading of mW18O49 affects the transparency of ACWx coatings, but all coatings still exhibit a transmittance of >83.9% at 550 nm. ACW0.5 and ACW0.65 composite coatings demonstrate remarkable NIR-induced self-healing ability and meet the application requirements of automotive varnishes in terms of adhesion, flexibility, hardness, gloss, acid and alkali resistance.

Summary: Zirconium and its alloys are widely used in orthopedic, dental, and hard tissue implants due to their high biocompatibility and corrosion resistance, but surface modification is essential for durable medical applications. Plasma electrolytic oxidation (PEO) can produce a uniform, thick, hard, and sticky oxide coating on the surface of zirconium, allowing for controlled coating properties to enhance bioactive and biocompatibility behavior.

Summary: The method used for membrane preparation and nanoparticle incorporation can impact the properties of the membranes. This study compared the use of Evaporation/Non-solvent Induced Phase Separation (EIPS/NIPS) and dip coating methods to obtain membranes containing PBAT and nanoclay. The EIPS/NIPS membranes showed smaller pores, more homogeneous pore diameter distribution, better mechanical properties, and lower production cost compared to the dip coating membranes. EIPS/NIPS method is economically and statistically advantageous, and holds potential for applications in removing pollutants from aqueous media.

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: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

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.
