Experimental Fab facility (Ex Fab) (previously known as nSiL) complements the resources available in the main SNF cleanroom. These spaces allow researchers to integrate “bottom-up” synthetic chemical methods with the “top-down” device processing methods to create new nanostructure-based materials and devices. Specific areas of focus are the synthesis, functionalization, and manipulation of nanoparticles, nanostructures, microstructures and surfaces.
