The celebration of the WORLD MATERIALS DAY 2018 will take place at the Faculty of Engineering of the University of Porto (FEUP), on November 7. As usual since 2003, a competition, with prizes, is organized to distinguish the best theses on Science and Materials Engineering from finalist students of the 2nd cycle courses in Sciences and Engineering, including Polytechnic Institutes, for the academic years 2016-2017 and 2017-2018. The FEMS-Federation of the European Materials Societies, of which SPM is a member, will award the FEMS award for the best master thesis in Europe. The winners of each member society will present their theses the following year at the Junior EUROMAT (odd years) or EUROMAT (even years) conference. Thus, the SPM Prize will consist of financing the travel and stay of the candidate who has won the Prize. The theses to be submitted should be practical, through the development of a material / product / technology with industrial application in the short term and with an impact on the materials used.
