Dr. Julio de Paula Seminar
Sceptical Chymists Virtual Seminar Series - Dr. Julio de Paula
Please join the Sceptical Chymists for our first seminar of the semester on Zoom. Dr. Julio de Paula, Professor of Chemistry at Lewis & Clark College, will be presenting his seminar titled "Light + Color = Chemistry + Archaeology"

Abstract: Atomic and molecular spectroscopy techniques familiar to physicists and chemists can be deployed in the field to provide useful information about objects recovered from archaeological sites or manuscripts and paintings housed in churches and museums. The first part of this presentation will describe investigations of a 16th century Book of Hours housed at Lewis & Clark College and several 15th century paintings housed in the museum of the Church of Sant Jaume in Alcúdia, Spain. The focus is on the analysis by X-ray fluorescence and Raman spectroscopy of pigments used in the paintings and the manuscript’s illustrations. We found evidence of undocumented restoration of some of the paintings, whereas the manuscript appears to be in its original condition. The second part of the presentation will describe an educational project related to our research activities: a free suite of online resources on analytical spectroscopy consisting of a textbook, video tutorials, and an inexpensive laboratory program in English, Portuguese, and Spanish.
Thursday, March 4 at 11:30am to 12:30pm
