Summary: Biomaterials with higher strength and increased bioactivity are being widely researched for scaffold and implant fabrication. Metal-based biomaterials are ideal for load-bearing implants due to their impressive mechanical and structural properties. However, the mismatch between the mechanical properties of the human body and the pure metallic implant can cause damage. This study aims to combine a biocompatible ceramic with metal to lower the overall mechanical strength and enhance the composite's bioactivity. The fabricated Ti-mu-HAp composites show a decreasing trend in nano-mechanical and micro-hardness properties, confirming their ability to minimize stress-shielding impact.

Summary: This paper quantified the elastic properties and fracture toughness of silicate bioactive glass-ceramics based on the 47.5B parent composition through nanoindentation for the first time. The effect of sintering temperature on the properties was investigated. Higher temperature sintered samples exhibited higher elastic modulus and fracture toughness compared to lower temperature samples. The mechanical suitability of the materials for bone applications was supported by their comparable properties to similar bioactive glasses in literature. An estimation of tensile strength as a function of flaw size was also provided.

Summary: The study focuses on utilizing hydroxyapatite as a surface protection material to reduce residual lithium compounds in Ni-rich cathode materials, resulting in enhanced cycling stability and capacity retention of the battery. This modification significantly suppresses morphological degradations and delays micro-cracking during electrochemical reactions, ultimately prolonging the cycling life of the battery.

Summary: The researchers have developed a novel and multifunctional hydrogel wound dressing, which can achieve rapid hemostasis and promote wound healing. The hydrogel is composed of two interwoven networks, one consisting of Bio-ILs and methacrylated hyaluronic acid (MeHA) and the other consisting of oxidized hyaluronic acid (OHA) and e-Poly-(L-lysine) (e-PL). In vitro studies have shown that the hydrogel has a porous structure, good swelling, antibacterial properties, and biocompatibility. Rat tail amputation and wound healing experiments have demonstrated the ability of the hydrogel to achieve rapid hemostasis and promote wound healing. In conclusion, the Bio-IL/MeHA/OHA/e-PL hydrogel is a naturally-derived, biocompatible, and promising wound dressing.

Summary: The cold sintering process can address the issues of high-temperature sintering and enhance the mechanical and functional properties of materials, particularly in the case of biomedical materials such as alumina-hydroxyapatite nanocomposites. This study successfully demonstrated the fabrication of hydroxyapatite nanocomposites with significant hardness and full densification using cold sintering, along with improved osseointegration behavior indicated by protein adsorption on the surface of the samples.

Summary: Beta-dicalcium silicate ceramics were synthesized using rice husks and chicken eggshells and sintered at different temperatures to investigate their properties. The ceramics sintered at the optimized temperature of 1100 degrees C showed the highest purity. With the increase in sintering temperature, the grain and pore size of the ceramics increased while the grain boundary density decreased, resulting in a decrease in breakdown strength.

Summary: This study investigates the effect of calcination on the physicochemical and biological properties of nanoHAP, as well as the influence of doping with magnesium, strontium, and zinc. The results show that calcination induces particle agglomeration and changes in surface morphology of nanoHAP, but ion substitution does not affect the apatite structure. The combination of calcination and ion modification promotes cell proliferation and osteoblast response.
