Abstract:
Atomistic simulation of materials: a tool to merge fundamental science and applications
In this talk we will present our work on atomistic simulation of materials with emphasis on 3 topics where fundamental science and applications meet. First, we present a study on the effect of gamma ray irradiation on the mechanical integrity of cement-based materials. This is of particular importance to the durability of the concrete shield of nuclear power plants. Second, large electric fields either naturally exist at materials interfaces or they are intentionally applied in applications such as deionization or ceramic sintering. Herein, we detail the effect of large electric fields on the thermodynamic and kinetics of charged defects in a solid. Finally, we describe a framework to understand charge redistribution at the interface between a solid and an aqueous solution. Such interfaces are common in energy conversion devices and in CO2 capture systems. The latter topic is the entry point to the proposed work at IEM.
Bio:
Mostafa Youssef is a new Chaire de professeur junior (CPJ) at the university of Montpellier. In 2006, he received his B.Sc. from Alexandria University, Egypt, with a major in nuclear and radiation engineering. Youssef pursued graduate studies in the area of computational nuclear materials at Massachusetts Institute of Technology (MIT) in Cambridge, USA, until he obtained his M.Sc. and PhD in 2010, and 2013, respectively. From 2013 to 2016, Youssef conducted postdoctoral research at MIT in computational thermodynamics of ceramic materials. From 2017 to 2024, Youssef was an associate professor in the department of mechanical engineering at the American University in Cairo. His research lies in the area of atomistic simulation of materials.
