I think that was a good effort to bring scientists from a wide range of countries and expertise's. Since I am working on Metallurgy, the talks were not of direct impact on my business; however, some of them were useful to my general information and it was a good chance for me to become familiar with nanotechnology. About the quality of the presentations, some people were using PowerPoint slides of languages other than English. I think it would be a good idea to request them to use their texts only in English.
