Electron Beam Artifacts in Liquid-Cell Electron Microscopy
  Bubbles may form when imaging liquids with in situ liquid-cell electron microscopy. Fluid dynamics videos show beam-induced bubble nucleation and growth. By examining the bubble formation and growth process, we hope to gain a better understanding of interactions between the electron beam and liquids.
