title: Hidden motion made known - rotational X-ray tracking reveals spinning colloids.
abstract: Rotational x-ray tracking (RXT) is demonstrated as a promising new tool for investigating previously unobservable motion in crystalline nanoscale colloids. Its potential utility is demonstrated by applying it to measurements of the local viscoelastic properties of a gel-colloid nanocomposite.
