Summary: An acrylic resin guide rail was designed and 3D printed to facilitate femtosecond laser surface microstructuring on zirconia dental implant, resulting in two surface topographies: microgrooves and nanoparticles. The fracture strength of control, microgrooved, and nanoparticles implants were 907.8 +/- 59.0 N, 793.7 +/- 83.3 N, and 755.6 +/- 144.5 N, respectively. Using femtosecond laser with the advocated guide rail is an effective method to fabricate micro-nano hierarchical topographies on zirconia dental implants precisely.

Summary: A biomimetic mineralized (Mg, Zn, Sr) carbonated amorphous calcium phosphate (cACP) coating containing biodegradable polycaprolactone (PCL) was prepared using spin coating technology. The PCL provided a controlled release of cACP and acted as a bioadhesive, improving adherence compared to pure cACP powder. The cACP coatings and the cACP-PCL composite showed increased cell viability and biocompatibility on a titanium alloy substrate.

Summary: Bone defects pose challenges to surgery and require cell-guided bioengineering methods for support and restoration of bone function. This study investigated the use of iron-reinforced hydroxyapatite nanorod, collagen/polycaprolactone, and tannic acid to create inorganic-organic nanofibers for coating an implant surface. The results demonstrated that the nanocomposite mimics the bone matrix, promoting cell attachment, proliferation, differentiation, and bone remodeling. It shows great potential for enhancing osteointegration.

Summary: Microbial infection is a significant threat to human health globally, and with increasing bacterial resistance, the development of nonantibiotic-dependent therapies is crucial. In this study, Cu2Se/Bi2S3 nanocomposites were constructed as agents for both chemodynamic therapy and photothermal therapy. These nanocomposites demonstrated synergistic bactericidal efficiency through peroxidase-like activity and near-infrared-induced hyperthermia, effectively targeting Escherichia coli and Staphylococcus aureus without causing significant cytotoxicity. Furthermore, the Cu2Se/Bi2S3 nanocomposites showed excellent healing outcomes in treating S. aureus-infected wounds.

Summary: In this study, nanocrystalline-Hydroxyapatite (n-HA) was combined with Polymethyl Methacrylate (PMMA) bone cement-Elastin (ELN) to produce a bone cement for orthopedic applications. The adaptability, weight loss, and pH change of the bone cement were evaluated using simulated body fluid (SBF) and phosphate-buffered saline (PBS). The morphology and microchemical analysis of the bone cement materials were examined using Field Emission Scanning Electron Microscopy (FE-SEM) and Energy-dispersive X-ray Spectroscopy (EDX). The mechanical properties, such as elastic modulus and impact strength, were measured using tensile test and Charpy impact test. The study found that the bone cement had low water absorption and porosity, and exhibited proper mechanical performance. This research is significant for the development of bone application materials.

Summary: In this research, hydroxyapatite powder particles were coated on a Ti-6Al-4V alloy substrate using the plasma spraying method. The study aimed to take advantage of titanium's mechanical properties and hydroxyapatite's biological properties to create bone implants. Preheating the substrate was found to improve adhesion and reduce residual stress, however, it also resulted in the formation of an amorphous phase in the coating, leading to weaker mechanical properties.

Summary: This study investigates the effects of incorporating various types of nanoparticles, both singularly and in hybrid form, on the low-velocity impact (LVI) response of glass fiber reinforced polymer (GFRP) composites. The experimental results reveal that specimens with a single loading of MWCNT or nano-clay have a lower maximum contact force compared to pure specimens with fully rebounding behavior. Furthermore, incorporating more MWCNTs results in stiffer behavior and more brittleness.
