Highly ordered mesoporous Co3O4 nanostructures were prepared using SBA-15 silica as hard templates. The mesoporous structures were characterized by X-ray diffraction, high resolution transmission electron microscopy, and N2 adsorption/desorption isotherm analysis. The results demonstrated that the as-prepared mesoporous Co3O4 has

Additive Manufacturing of Permanent Magnets

Permanent magnets are an essential technology for energy conversion. Motors and generators are used to convert energy between electrical and mechanical forms.

Biomedical Implant Devices Fabricated from Low Young’s Modulus Titanium Alloys Demonstrating High Mechanical Biocompatibility

Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as bones and teeth.
