ICNS 2016, 2017 and 2018 were significant scientific events in the field of Natural Sciences, which built a platform and brought speakers and poster presenters from various scientific disciplines together, to exchange and share their scientific achievements and ideas. The participation of innovative and expert keynote speakers and presenters, the well-organized tasks among the committee members, the well marketing and public relations, and the excellent and attractive place of the conference all made ICNS 2016, 2017 and 2018 successful events, all logistically and scientifically. While the ICNS 2016 and 2017 addressed Biology, Geosciences, Chemistry, Physics, Mathematics, and Computer. ICNS 2018 branches out to four separate conferences in Biotechnology, Chemistry & Geosciences, Mathematics & Computer, and Renewable Energy &Waste Energy.
