Silicides: Promising Thermoelectric Materials

In recent years, the price of tellurium, a key component in the bestperforming thermoelectric materials, has increased significantly, leading to the question, “Is it economically viable to produce thermoelectric generators on an industrial scale?

Silicides: Promising Thermoelectric Materials

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.

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.

Responsive Rare-Earth Materials and their Applications

The unique properties of the rare-earth elements and their alloys have brought them from relative obscurity to high profile use in common hightech applications.
