Equipment

Our laboratory is equipped with state-of-the-art materials synthesis and processing facilities including fume hoods, glove boxes, and arrays of tube and muffle furnaces with inert and reactive gas supply. Besides wet chemical routes, we dispose of dedicated co-precipitation, solvo-thermal microwave, and ultrasonic spray-combustion reactors for particle synthesis. Thin films can be deposited by spin coating, aerosol-assisted chemical-vapor deposition, and sputtering. Metallic alloys can be produced by arc melting and induction melting under inert atmosphere. Dense and porous ceramics are produced in our spark plasma sintering furnace and dedicated sintering furnaces. An optical float zone furnace is available for single crystal growth. Structural analysis is carried out in one of our two X-ray diffractometers or Raman spectrometer. Several Fourier transform infrared spectrometers are available, also with attenuated total reflection and diffuse reflectance. A Brunauer-Emmett-Teller (BET) analyzer allows surface area determination. Gaseous products are analyzed by gas chromatography and mass spectrometers. Complex impedance, electrical conductivity, Seebeck and Hall coefficients, thermal diffusivity and conductivity can be determined up to 800°C. Thermodynamic properties can be investigated using thermogravimetry or differential scanning calorimetry. Application specific test stands for battery cycling including several climate chambers, (photo-)electrochemical H2O and CO2 reduction, alkaline electrolysis, thermal catalysis, and thermoelectric module testing are also operational.
