The World Symposium on Environmental Science and Engineering (WSESE 2018) is organized by the International Association of Engineers (IAENG), a non-profit international association for the engineers and the computer scientists. The conference has been formerly part of The 24th International MultiConference of Engineers and Computer Scientists (IMECS) 2016. The conference has the focus on the frontier topics in the theoretical and applied materials science and engineering subjects. The WSESE conference serves as good platforms for our members and the entire materials engineering community to meet with each other and to exchange ideas in small groups and to discuss the frontier topics in details. Our IMECS committees have been formed with committee members who are mainly research center heads, faculty deans, department heads, professors, and research scientists. The last IMECS conference has attracted more than seven hundred participants from over 50 countries.
