Dr. Michelle Personick

Course Summary

This graduate-level course focused on the application and use of various physical techniques to analyze inorganic nanomaterials. Aptitude was examined with final projects including an oral presentation and written project proposal.

Skills

Research: proposal writing, communication

Analytical techniques

• Scanning Probe Microscopy (AFM, STM)
• Electron Microscopy (SEM, TEM, STEM)
• X-ray Spectroscopy (EDX, AES, XPS, XAFS, XRD, SAED, EELS)
• Vibrational Spectroscopy (IR, Raman, DRIFTS, SERS)
• Optical Spectroscopy (UV-Vis, Fluorescence, Emission)

Nanomaterials in extreme environments

The final assignment for this course involved designing a research project in nanomaterials characterization. I proposed a project related to cultural heritage conservation, examining the structural changes of silica-consolidated materials after exposure to extreme environments. I presented my proposal in both written and verbal form; my verbal presentation received full marks from my professor, with an emphasis on providing necessary context to conservation science and consolidation treatments.

Literature review of oxide nanoparticles

My proposal specifically focused on the use of silica nanoparticles in their applied use for consolidation on materials including Beech wood and Portland cement. I conducted literature review on similar studies performed in the fields of materials science and cultural heritage to gain a comprehensive perspective on the characterization of oxide nanoparticles. I analyzed studies that examined other oxide nanoparticles including titania, or similar systems including asphalt.

My written proposal is attached below, for which I received full marks.
