Very good in general. It gave me the opportunity to present my research work to a diversified scientific community. This could increase or enlarge the opportunities for future cooperation projects. It was a success in favor of pluridisciplinary aspects between different scientists' horizons. Pluridisciplinary aspect is important for the development and good work of future scientific projects based on different expertise. Finally, I underline my high consideration of having participated in the 4th summit of Future Material Sciences and Research.
