Center for Integrated Nanotechnologies (CINT)
At CINT, we have found new research opportunities in liquid phase scanning/transmission electron microscopy (S/TEM) through a combinatorial experimental approach that includes exhaustive characterization of real-world-relevant materials prior to in-situ experimentation, and increasing environmental control over the sample. This experimental technique has successfully imaged, in real-time, the assembly of nanomaterials, the growth of nanocrystals, electrochemical reactions, temperature-controlled liquid-phase reactions, dynamics of nanoscale biomaterials, and solid-liquid interfacial reactions. We have developed microelectromechanical systems (MEMS) platforms, at Sandia National Laboratories’ Microfabrication Facility, to exceed commercial technologies available for sample control in these environmental sample holders. The use of this technique/instrumentation to investigate Li-ion anode materials and steel corrosion will be highlighted.
