Scientists routinely use microscopes to unravel the structure of materials down to the atomic scale. Knowing the structure and properties independent from each other, is only one piece of the puzzle when trying to understand the functionality of a material or device. In situ and operando microscopy helps to connect material structure and property. It provides a platform where materials are observed while an external stimulus is applied and, simultaneously, the materials’ reaction is quantified. Replicating real materials’ operational environments in an electron or x-ray microscopy is challenging. New instrumentation has enables researcher to overcome these challenges, for example, by providing environmental cells that allow to image materials in liquids or gases in compliance with the somehow stringent microscopes’ vacuum requirements. In this presentation will present new tools and results showing how this idea of in-situ/operando electron and x-ray microscopy is being used to tackle problems in the fields of electrochemistry, particles self-assembly, devices fabricated with 2D materials, crystal growth, etc.


In 2005, Norman Salmon co-founded Hummingbird Scientific along with Dr. Eric Stach. In the years since, Mr. Salmon has led the company’s growth and engineering development. Mr. Salmon has been involved in precision manufacturing for over 25 years. As program manager at Lawrence Berkeley, he focused on precision mesoscale manufacturing and instrumentation for electron microscopes. He has consulted for more than 50 organizations, including government agencies, medical manufacturing companies, precision machine tool builders, and manufacturers of precision components. As a principal investigator at Hummingbird Scientific, Mr. Salmon has received more than $15 million of funding from the Department of Energy Office of Basic Energy Sciences, the U.S. Army, and the National Institute of Health. He has co-authored several papers in journals including Journal of Materials Research, Journal of The Electrochemical Society, and Science. He is an active member of the American Society for Precision Engineering, Materials Research Society, and the Microscopy Society of America. Mr. Salmon earned a B.S. in Industrial Engineering Technology from Western Washington University.
