An overview of the main Tunisian scientists in chemistry and materials science

In this research paper,a ranking of the 61 main tunisian scientists in chemistry and materials science working in tunisia and abroad is provided. it is clearly seen that 37 out of 61 scientists are working in tunisia and this is explained by the tendency of tunisian universities having to work on interdisciplinary research that is known for providing more citations than theoretical and applied research. however,the performance of the tunisian main scientists working abroad appears superior to the one of the local tunisian main scientists. this is explained by the better conditions of research offered outside tunisia and maybe by a deficiency in their choice of international collaboration. a new policy should then be elaborated to improve the organization of such research collaborations and let them more fructuous.
