Application

Employed in the synthesis of metal-rich layered tellurides, TaNi2Te2 and TaCo2Te2, which possess ideal characteristics for photovoltaic applications, for surface scanning studies, and which may give clean and atomically flat surfaces.[1] Starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18, for which electron and stability studies were performed.[2]

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.
