Section Abstract and Authors
Plenary-1

Materials by Design: 3-Dimensional Architected Nanostructured Meta-Materials, J.R. Greer, California Institute of Technology

Creation of extremely strong yet ultra-light materials can be achieved by capitalizing on the hierarchical design of 3-dimensional nano-architectures. Such structural meta- materials exhibit superior thermomechanical properties at extremely low mass densities (lighter than aerogels), making these solid foams ideal for many scientific and technological applications.

In this talk, the history of scaling genomic assays and the associated technical innovations will be explored, as well as the ever increasing role of both top-down and bottom-up nanofabrication in further scaling of NGS technologies. The talk will conclude with an exploration of current scaling challenges, and how future innovation in nanofabrication will enable the continued evolution of NGS to provide cheaper and more complete genomes
