We demonstrated dynamical observation of an individual nanocrystal in supercooled liquid water with the guidance of x-ray diffracted spots from the nanocrystal itself. This new system, which we call diffracted x-ray tracking, monitored small Brownian motions (D=0.68 mrad(2)/s at 233 K) of a single nanoparticle in real time and real space.
我们在过冷液态水中，借助纳米晶体自身的X射线衍射斑点的引导，实现了对单个纳米晶体的动态观测。我们将这个新系统称为衍射X射线追踪，它能够在实时和实空间中监测单个纳米颗粒的微小布朗运动（在233K时D = 0.68 mrad²/s）。
