1. Investigation of the performance of polymer based outdoor insulators used in high voltage applications and development of a remote and real-time diagnostic technique for the evaluation of their functionality, Greek funded project implemented through the Operational Program ʽʽCompetitiveness and Entrepreneurshipʼʼ, Action "Cooperation 2011" (2013-2015).
The aim of this project is the investigation in a systematic way of the performance of polymer based outdoor insulators used in high voltage applications under the climatic conditions of Crete and Greece and the development of a remote and real time diagnostic tool for the on-the-field evaluation of their functionality. Towards this end, initially the physical/chemical parameters affecting the functionality of the insulators will be determined, so that the influence of ageing on the basic characteristics and the functionality of the insulators will be better understood. Afterwards, the performance of various optical techniques (like Spectral Imaging, Laser Induced Fluorescence and Laser Induced breakdown Spectroscopy) will be examined regarding lab and field scale recognition of the functionality of the insulators. Upon deciding on the more appropriate diagnostic technique, the respective model correlating the diagnosis results with basic characteristics and functionality of the insulators will be developed, tested and optimized. Finally, a prototype diagnostic tool will be developed and tested as well as new polymeric material will be designed, exhibiting properties suitable for outdoor composite insulators.
2. Growth and characterization of novel nanostructured layers suitable for the confinement of GHz electromagnetic radiation, Greek funded project implemented through the Operational Program "Education and Lifelong Learning" action Archimedes III (2012-2015).
The aim of this project is the growth and characterization of novel, efficient, low cost, environmental friendly and easily applied nanostructured layers based on carbon allotropes and metal/metal oxide nanoparticles, suitable for EMC in the GHz range. Three approaches are employed:
- Study of the GHz electromagnetic confinement of layers that offer the possibility of tuning their performance by modifying the nanostructures basic characteristics.
- Study of the dependence of the performance of the nanostructured layers on the frequency of the incoming radiation, and
- Investigation of the correlation between the electrical characteristics of the nanostructured layers and their effectiveness in EMC.
3. Photocatalytic active nanostructured coatings on fabric substrates for applications in air purification systems, PNII-RU-TE-2012-3-0202, grant of the Romanian National Authority for Scientific Research, CNCS – UEFISCDI (**792.220 RON).
The project is implemented in CEMATEP through the Bilateral collaboration agreement No594/14/05.2013 between the lab and the Chemistry Department of Al. I. Cuza University. (2013-2016)
The project has the following objectives:
- To obtain nanostructured ZnO based coatings on textile supports with controlled thickness, very good coverage, and robustness using as direct growth method different chemical simple routes (aqueous chemical growth, nonaqueous solution growth, and sol gel) using low cost precursors, and repeatability for potential commercial applications.
- To find the optimum material composition, structure and properties on each textile substrate and to achieve maximum surface to volume ratio for the active coating for each chemical growth method.
- To achieve materials with high photocatalytic activity against common air pollutants that can be used in indoor air purification systems.
- To create a small scale prototype reactor, integrating the best photocatalytic active ZnO based material onto textile support, with respect sustainability, feasibility and cost effectiveness for future scale up.
