Articles

Thermoelectric materials comprise a wide range of solid compounds distinguished by their ability to convert thermal and electrical energy.

Higher transition metal silicides are ideal for anisotropic thermoelectric conversion due to their Seebeck coefficient anisotropy and mechanical properties.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
