Advanced Materials & Electrochemical Technology Lab (LAMET)

Lab SupervisorDr. Nikolaos Kiratzis, Professor


The Laboratory of Advanced Materials & Electrochemical Technology (LAMET) focuses on research themes within  the area of fabrication of special functional ceramic as well as ceramic-metal (cermets) composites in the form of thin films suitable for applications such as ceramic fuel and electrolysis cells, ceramic membranes, gas sensors and heterogeneous catalysts. Towards this end, both conventional ceramic processing methods based on liquid dispersions (i.e. tape casting and/or slip casting)  as well as  innovative molecular deposition methods (such as solution spray pyrolysis) are used. There are also research directions towards  natural gas  utilization in ceramic fuel or electrolysis cells.

The Lab is equipped with:

  • Electrochemical testing and characterization apparatus (Probostat) for testing of elementary (button) cells in various operational modes interfaced with an Ivium electrochemical characterization system. The system set-up allows for simultaneous examination of the performance of various ceramic and/or cermet electrodes by means of an online mass spectrometer (up to a MW of 99) and gas chromatograph.
  • High temperature (cylindrical and muffle) furnaces for sintering of ceramic and mixed oxide materials at temperatures up to  1600°C allowing for programmable heating rates. There is also a low temperature drying furnace.
  • A planetary ball mill (FRITSCH) for mixing of liquid ceramic dispersions (12-45ml) up to a particle size < 1μm
  • Conductivity meter for liquid solutions
  • A gas pycnometer for measuring the density of porous pellets (operating with He or N2)
  • Electrochemical operation modes allowing for corrosion characterization, battery characterization and/or other types of electroanalytical and/or nano-electrochemistry measurements.
  • Solid electrolyte potentiometry (SEP) measurements for electrochemical characterization of metal and/or metal oxides and/or cermets (lamda sensors)

The Lab has supervised several degree theses of undergraduate students funded primarily by the ARCHIMEDES research initiatives (Title:  “Development of Solid Electrolyte Fuel Cell Systems for the direct electrochemical oxidation/dehydrogenation of hydrocarbons”) as well as a doctoral dissertation funded by a research grant  coded Archimedes III (“Optimization of fabrication processes of solid electrolyte fuel cell components for the direct  electrochemical oxidation of hydrocarbons”) in collaboration with Professor Irvine  of the Department of Chemistry at the University of St. Andrews, Scotland, UK  (Title: Optimization of spray pyrolysis for cathode-supported solid oxide fuel cells)
