Summary: A successful attempt was made to improve the mechanical properties of Hydroxyapatite (HAp) and reduced graphene oxide (rGO) composite nanoparticles (NPs). Different proportions of HAp and rGO were synthesized to enhance the mechanical properties. The HAp NPs were prepared using the wet precipitation method and calcination, while the rGO-HA composites were prepared through ball milling. The strength of the variants significantly increased with the concentration of rGO, while the porosity also increased.

Summary: This study presents a graph neural network-based approach that directly translates between mesoscale crystalline structures and atom-level properties, with a focus on the effects of structural defects. The method accurately predicts atomic stress and potential energy in systems with different defects, captures derivative properties and their evolution, and designs atomic structures with optimum global properties and target local patterns using a genetic algorithm.

Summary: In this article, ZrO2/Si-C-O ceramic fibers were synthesized using the sol-gel process combined with the electrospinning technique. The effects of increasing heat treatment temperature on the composition, structure, and morphology were investigated. It was found that the temperature increase led to an increase in fiber diameter and grain size, as well as a transformation of the ZrO2 phase. The ZrO2/Si-C-O ceramic fibers exhibited refined crystalline grain and improved mechanical properties at a heat treatment temperature of 800 degrees C, making them suitable for high temperature environments.

Summary: The relationship between design parameters and mechanical properties of composite PCL and nHAp scaffolds fabricated by 3D printing was explored in this study. The results demonstrated that the microstructural parameters of the scaffolds were related to their design, and the mechanical properties were affected by scaffold height. Compared to scaffolds with 4 layers, the increase in height had varying effects on the elastic modulus and yield strength. Lattice scaffolds exhibited more stable mechanical properties, while lower height scaffolds showed more promising results in terms of mechanical properties.

Summary: Highly sinterable Tm,Ho:(Lu1-xScx)(2)O-3 nanopowders were synthesized using a spray co-precipitation method, and the effects of calcination temperatures and x values on the powder properties were investigated. The powders calcined at 1100 degrees C for 2 hours showed the highest sintering activity, leading to the fabrication of Tm,Ho:(Lu1-xScx)(2)O-3 ceramics with high in-line transmittance of 79.80% at 2090 nm. This work demonstrates the potential for producing Tm,Ho:(Lu1-xScx)(2)O-3 transparent ceramics for various applications.

Summary: Selective Laser Melting (SLM) technology is effective for fabricating complex shape parts with superior strength and ductility. However, the high-temperature gradient and rapid solidification rate in the SLM process led to unstable material microstructure, affecting the mechanical properties. Research shows that solution treatment of SLM-fabricated duplex stainless steel can improve elongation and result in mechanical properties superior to forged specimens.

Summary: In addition to grain size, other factors such as texture, distribution of alloying elements, and homogeneity of the microstructure also affect the mechanical properties and corrosion resistance of magnesium alloys. This study investigates the effect of grain size on tensile properties, hardness, and bio-corrosion resistance of commercially pure magnesium through grain growth annealing and hot rolling. The grain growth kinetics and corrosion behavior of commercially pure magnesium are analyzed, and the results show that grain coarsening enhances corrosion resistance.

Summary: Articular cartilage degeneration is a challenging issue with limited repair capabilities. Tissue engineering strategies using appropriate scaffolds for chondrogenic differentiation of stem cells can be a promising solution. This study investigated the influence of two genipin crosslinking routes on collagen-based scaffolds and found that bulk crosslinking with genipin resulted in a more uniform and homogeneous deposition of chondral-like matrix.

The authors demonstrated that DLP printing is not only suitable for developing microfluidic devices, but also capable of reproducing small features rapidly. The fabricated devices exhibited good transparency and mechanical strength.
