Knowledge of precise thermophysical parameters, such as heat capacity and thermal conductivity, is crucially important in many thermal systems, particularly heat pumps and chillers.
A particular emphasis of work at the ServiceLab Thermochemical and Porous Materials therefore lies in evaluating and characterizing porous materials for sorption applications, including zeolites, silica gels, silicoaluminophosphates (SAPOs), aluminum phosphates (AlPOs), metal-organic frameworks (MOFs) and activated carbon.
As part of our characterization services, we analyze pore structure and surfaces using gas adsorption and mercury porosimetry. We further evaluate how the porous materials adsorb various media (e.g. refrigerants), such as water, methanol, ethanol, propane/propene, as a function of temperature and pressure/humidity.
In addition, we are able to analyze heat capacity, measure surface structures and particle sizes on the nanoscale using laser microscopy, analyze crystal structures by means of X-ray powder diffraction (XRD) and determine framework density using a helium pycnometer.
The analysis lab draws together the longstanding experience gained at Fraunhofer ISE in analyzing and characterizing different materials.
