A multi-institutional team of scientists has used beamline 9.0.1 at the Advanced Light Source to perform high-resolution x‑ray diffraction imaging of an aerogel for the first time, revealing its nanoscale three-dimensional bulk lattice structure down to features measured in nanometers, billionths of a meter.Aerogels, sometimes called "frozen smoke" or "San Francisco fog," are nanoscale foams: solid materials whose sponge-like structure is riddled by pores as small as nanometers across.
