　　Abstract of the lecture:

　　Continued advances in engineering technologies with increased complexity, enhanced performance and new capabilities, demand novel material systems with unprecedented properties as well as novel manufacturing approaches to accelerate the transfer of lab-scale inventions to the marketplace. Advanced materials, such as nanotubes and nanofilms, were demonstrated to be promising candidates for various applications including energy storage, electronics and transportation vehicles. Before advanced materials-based inventions can be widely applied to everyday life, their mechanical stability needs to be investigated, validated and engineered because it determines their long-term viability in all their applications. Also, by understanding the mechanical behaviors of advanced materials, novel material systems with tailored mechanical properties can be rationally designed for targeted applications. In this talk, I will use graphene oxide as a representative material to showcase the experimental explorations of its multiscale mechanical behaviors from sub-nanometer scale to microscale as well as development of printing technologies for the assembly of functional structures.
