Symposium Technical Description
Graphene is a two dimensional (2D) material with an array of remarkable electronic, mechanical, chemical, and optical properties. Inspired by the synthesis of graphene, a host of other 2D materials have been discovered (such as transition metal-dichalcogenides, hexagonal boron-nitride, and so on) that can be stacked in different order and orientations to create 2D layered materials with novel properties. Recently, piezoelectric phenomena and deformation-induced structural phase transition in transition metal-dichalcogenides have also attracted significant attention. Moreover, feasible functionalization on the surface of 2D materials offers the possibility of physically or chemically interfacing 2D materials with other nanoscale building blocks for unconventional nanocomposites. Thus 2D materials and 2D-based nanostructures offer exciting possibilities for the creation of multifunctional nanostructures with applications ranging from materials design to energy and the environment.
This symposium aims to bring together experts from the mechanics and material science communities to exchange ideas related to fundamental understanding of the mechanics and physics of 2D materials and 2D-based nanostructures and their technological applications. An example is the development of nanocomposites containing 2D materials, which require an understanding of the load transfer mechanism between components. A key area of interest is the development of predictive methods for modeling 2D layered materials and nanostructures. This is challenging since due to the weak van der Waals interaction between layers, the resulting structures can be incommensurate. Another challenge is how to leverage the extraordinary properties of 2D materials and nanostructures at the device level. Designing such devices requires multiscale computational and experimental methods. Topics in the symposium will include but are not limited to:
- Fabrication, characterization and testing of 2D and 2D-based nanostructures;
- Atomistic and multiscale computational methods for 2D and 2D-based nanostructures;
- Properties of incommensurate 2D materials;
- Surface buckling of 2D materials: ripples, wrinkles, and bubbles;
- Thermo-Electro-Mechanical properties of 2D materials;
- Interfacial properties of 2D materials (van der Waals interactions and beyond);
- Tribology and wear of 2D materials;
- Defects and fractures in 2D and 2D-based nanostructures;
- Structural phase transition in 2D materials;
- Graphene and graphene oxide based nanocomposite;
