A basic screening of new compounds and materials created in the Inorganic Chemistry and Chemical Metal Science departments is the task of the Physical Characterization labs. Special provisions have been developed which allow also measurements on highly air and moisture sensitive materials. The instrumentation is also used for in-depth physical investigations, e.g. of skutterudites, borides, thermoelectics, borophosphates, carbometalates, nitrides, low-dimensional spin systems and novel superconductors.
