Concurrent and Hierarchical Particle Continuum Bridging: A Journey Through Realistic Molecular Models of Soft Matter

Speaker: Giuseppe Milano; Dipartimento di Chimica e Biologia, University of Salerno, Italy
Current developments and Coarse-Graining schemes bridging particle and continuum descriptions aimed to achieve models retaining molecular specificity will be described. In particular, descriptions based on a concurrent combination of molecular models and self consistent field theory and hierarchical approaches bridging atomistic models and finite elements methods (FEM) will be described. These approaches allowed to develop models having chemical specificity but at the same time open the possibility to simulate large-scale soft matter systems. Current developments and several applications ranging from biomembranes,[1-3] self-assembled structures  to drug delivery , polymer melts , polymer composites, and gas sensor devices  will be described.References
