  • Lecture: Romanian Icons on Glass, with Mihaela D. Leonida, Professor of Chemistry, Fairleigh Dickinson Univ., Saturday, November 17, 2012, 3 p.m.

Peasant icons on glass offer the strange image of a folk art, clearly outlined and unique in its technical quality and sensitivity. It is the result of the harmonious merging of moralizing teachings and the mythology of an ancient faith, of subjects taken from the Romanian folklore, from apocryphal books, and the precepts of a local ethical code, thousands of years old. The slight emotional emphasis therein is on the national and social context of a people with a stormy and too frequently changing history.

The talk introduces the Romanian icons on glass in the cultural environment of Central and Eastern Europe making comparative notes and historic connections. Less known information about how the peasant iconographers prepared their own materials and the technical skills they mastered in creating these icons is presented together with many examples of icons on glass from different geographical areas of today’s Romania.

RESEARCH INTEREST


I am interested in stabilizing redox enzymes and making them conduct current. Several strategies to achieve this were reported by us, among which “wiring” had an important role. The modified enzymes were used in biosensors for medical and environmental applications and in the synthesis of compounds interesting for the pharmaceutical industry.

Nanocomposite materials based on natural compounds are another topic of interest for me. Our syntheses target products with antimicrobial, antifungal, and antiproliferative activity. We test them as potential drug carriers, in cosmetic formulations, or in cleaning agents.

I am also interested in the materials and techniques used by medieval artists.
