Summary: A growing trend is to use bioactive ceramics to develop bone scaffolds. Improving the bioactivity and osteoinductive ability of biphasic calcium phosphate (BCP) scaffold is important. Polydopamine (PDA) coating, chitosan (CS) coating, and their composite coatings can improve scaffold bioactivity. CS/PDA coating has the greatest effect in improving cell viability and promoting osteogenic differentiation.

Summary: This study explores the use of Voronoi tessellation design in 3D-printed mPCL-HA composite scaffolds for scaffold-guided bone regeneration (SGBR). The results suggest that the Voronoi design allows for slow degradation and high osteogenicity, promoting tissue regeneration and bone formation without adverse reactions. The mPCL-HA Voronoi scaffolds have the potential for further preclinical animal studies before clinical trials.

Summary: This article presents a sustainable strategy for collecting freshwater from the atmosphere using hygroscopic salt-based composite sorbents. A hierarchically structured scaffold is developed through 3D printing combined with freeze-drying, which integrates cellulose nanofiber and lithium chloride (LiCl) to expose more hygroscopically active sites while preventing salt leakage. The scaffold exhibits enhanced water sorption and release rates and demonstrates significant potential for outdoor water harvesting under natural sunlight.

Summary: With the rapid development of MEMS, micro/nanoscale fabrication of 3D metallic structures with complex structures and multifunctions is becoming increasingly important. Micro/nanoforming, as a promising micromanufacturing approach, has advantages but is far from being well-established, and is currently a hot research topic.

Summary: The study on coalescence and melting process of Ag and Cu nanoparticles using molecular dynamics found that twin boundaries or stacking faults and atomic diffusion play key roles. Initially, Cu and Ag nanoparticles quickly contact each other, forming stable interfaces with potential faults or boundaries as temperature rises. At a critical temperature, atoms diffuse strongly to ultimately melt into a liquid sphere. The coalescence point and melting temperature increase with cluster diameter, with nanoparticle arrangement affecting initial interface stability and subsequent behavior.

Summary: The study found that at 77K, the strength and ductility of thin sheets of pure copper are higher, especially for samples with larger grain sizes. The results also indicated that there was a higher dislocation density and more homogeneous dislocation distribution at 77K compared to 295K. A new constitutive model was established to explain the effect of cryogenic temperature on the deformation mechanism of thin sheets of pure copper, suggesting that micro-plastic forming at cryogenic temperature could enhance the formability of copper and similar metals.

Summary: Nickel-based superalloys have excellent properties as key materials for aircraft engines. Microtensile experiments were conducted to investigate the effects of the delta phase on grain orientation, surface roughness, and strain localization. The results showed that the presence of the delta phase increased the fracture misorientation and decreased surface roughness, while increasing strain localization. Plastic strain led to the growth of voids, and the rod-like and needle-like delta phases provided channels for microcrack propagation, ultimately leading to specimen fracture.

Summary: This paper explores the strain rate sensitivity of CG Cu/Ni clad foils, showing that strength and ductility increase with strain rate, and the strain rate sensitivity is three times higher than that of CG pure Cu. The formation of edged dislocations at the interface layer contributes to improved ductility and strain rate sensitivity in the clad foils. Size effect on mechanical properties is consistently present in the quasi-static strain rate range.
