Allgemeine Beschreibung

The structure of tantalum is body centered cubic (BCC) metal. It is a refractory metal; stable up to very high temperatures. Tantalum is ductile at room temperature and moderately ductile at cryogenic temperatures. Compton profile of highly pure thin elemental foil of tantalum was investigated using IGP type coaxial photon detector.1

Anwendung

0.05mm thick tantalum foil was filled with 12C or 13C powder to act as carbon source emitting low energy carbon atoms.

Combinatorial Materials Science for Energy Applications

Can there be an effective strategy for finding breakthrough materials, since they are, by definition, unpredictable? One answer is found in Combinatorial Materials Science techniques, which represent a powerful approach to identifying new and unexpected materials.

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.
