The Aerosol and Particle Technology Laboratory (APTL) was established in 1996 within CPERI/CERTH with the rationale that the solution of many environmental, health, energy, materials and process industry related issues relies on understanding and exploiting the science of fine particles and their suspensions in various media. Recognizing the opportunities offered by this diverse, yet based on common grounds, set of applications, our objectives are to conduct basic and applied research as well as to develop new technological products in these niche areas, responding to well acknowledged market needs in the areas of clean transport, clean energy and in-situ process monitoring.
