Tremendous recent progress in nanofabrication capabilities has made high-quality single atomic\ layers and nanostructures with dimensions well below 50 nm common place, enabling unprecedented\ access to materials at the nanoscale. However, tools and techniques capable of characterizing\ the properties and function of nanosystems are still quite limited, leaving much of the\ fundamental physics that dominates material behavior in the deep nano-regime still unknown.\ Further understanding gained by studying nanoscale materials is critical both to fundamental science\ and to continued technological development. This thesis applies coherent extreme ultraviolet\ (EUV) light from tabletop high harmonic generation to study nanoscale systems on their intrinsic\ length and time scales (nanometers and femtoseconds, and above), specifically following thermal\ transport and acoustic dynamics. These studies have shown where and how nanostructured material\ properties can be quite different from their bulk counterparts. This has in turn allowed us to\ develop new theoretical descriptions to guide further work.
