Research in the EM Facility - 2009/2010

Academic Year 2006/2007, 2007/2008, 2009/2010

There are several students in various fields of study who are currently engaged in research projects that utilize the Electron Microscopy Facility. They are:  

Chemistry - Studies of local historical artefacts

Fragment from Hellcat aircraft
Lan Anh Tran (2013)

The SEM makes possible the study of archeological artefacts recovered from digsites of historical interest. This project involves morphological and elemental analysis of fragments of a Hellcat aircraft at Bradley Airfield north of Hartford, a crash site that is decades old. Lan Anh uses the SEM and XEDS to study the fragments and determine their nature.

Chemistry & Classics - Studies of Archeological Artefacts

Potsherds from Ancient Pottery (SEM and X-ray Energy Dispersive Spectroscopy)

Lan Ann Tran (2013) and Sam Gauthier (2012)

The SEM makes possible the study of archeological artefacts recovered from digsites of historical interest. This project involves morphological and elemental analysis of ancient pottery from Israel, materials provided by the Classics Dept. The top image is representative of one of the polished potsherds recovered several summers ago as visualized by Secondary Electrons in the SEM (Scanning Electron Microscope). The inclusions in the middle image, using Backscattered Electrons, display different shades of gray as defined by the different elements present. Chemical analysis by X-ray Energy Dispersive Spectroscopy confirms their variable composition as shown in the bottom image, an XEDS spectrum.
