Summary: The design of porous structure that mimic trabecular bone can optimize the properties of titanium alloy implants. Increasing the porosity and average pore size can decrease the mechanical properties of the scaffold, but improve the permeability and nutrient transport. Cell experiments showed that reducing the average pore size enhanced cell adhesion and proliferation. Animal experiments showed that the scaffold with 65% porosity and 550 μm pore size had the most significant new bone formation effect.

Summary: This study investigated the thermal release of helium from dispersion-strengthened tungsten. Thermal desorption spectroscopy was performed after irradiation at 1073 K to a 10(24) m(-2) fluence to elucidate the helium trapping and desorption behavior. Post-desorption microscopy was used to correlate the microstructural changes with helium release spectra. The results showed that the amount of desorbed helium was highest in the 1.1 and 5 wt% alloys, and significantly lower in the 10 wt% alloys. Helium bubbles were observed in the pure tungsten and 1.1 wt% alloys. The results emphasize the importance of tailoring grain size and oxide vacancy concentrations on the helium retention and release behavior in dispersion-strengthened tungsten alloys.

Summary: Chemical and physical surface modification methods, such as direct irradiation synthesis (DIS), have been successfully used to address stress shielding and osseointegration challenges in bone regeneration. DIS generates self-organized nanopatterns on the surface of materials, enhancing their mechanical properties and topography for better osseointegration. By adjusting the volume percentage of spacer NaCl particles, the porosity and morphology of the material can be controlled. These nanoscale features are biocompatible and promote cell differentiation and mineralization, making them promising for bone tissue engineering.

Summary: The thermal stability, mechanical properties, and scratch resistance of PEEK/RGO nanocomposite coatings were analyzed and discussed based on their nanosheet content and microstructure. The addition of RGO slightly affected the thermal stability of the coatings, but did not limit PEEK processing. The presence of RGO influenced the morphology, crystalline phase, and near-to-surface mechanical properties of the coatings, as well as their scratch damage mechanism. The comprehensive characterization indicated that PEEK/RGO coatings are suitable for applications requiring tribo-mechanical resistance.
