"In Situ Liquid Cell Electron Microscopy with the NanoAquarium: A Study in Electrochemistry and Radiation Chemistry"
Advisor: Dr. Haim Bau

The advent of Electron Microscopy has fostered major advances in a broad spectrum of disciplines. The required vacuum of standard electron microscopy precludes imaging of process and objects suspended in liquid media. Many important processes, such as the potentially catastrophic formation of dendrites during battery cycling, take place in liquid systems. The recent development of liquid cells like the NanoAquarium overcomes this limitation, enabling imaging of temporally evolving processes in liquid systems with nanoscale resolution. I will describe the use of the NanoAquarium to investigate the morphological evolution of the electrode-electrolyte interface during electroplating and stripping of electrodes, nanoparticle growth and assembly, and the fundamentals of beam-irradiated medium interactions (Radiation Chemistry). The results of my work are applicable to battery technology and to nanomanufacturing.
