The Cloister And The Square: Gender Dynamics In Renaissance Florence, Soph Garrison

Epochs Art History Journal

The cyclical perpetuation of patriarchal ideals within Renaissance Florence reveals the consistent suppression of femininity throughout history. Through the displacement of feminine imagery coupled with the increase of hypermasculinization and phallic imagery, the intricacies of gender dynamics expose their trivial nature and execution. Although the primary perpetrators remain up for debate, religious culture sought to not only silence feminine individuals but to control them indefinitely. As such, the art produced during the rise of the Florentine Republic displays the rejection of femininity and the endorsement of masculine depictions of values. Mary Garrard’s assessment of gender dynamics in Renaissance Florence aligns …

Studies Of Exotic Electronic, Optical, And Electrochemical Properties In Nanoparticle Assembly And Graphene, Jay Min Lim

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

It is well known that exotic properties and phenomena emerge as structural dimensions shrink to nanoscales. We self-assembled one-dimensional chains of gold nanoparticles in solution and quantified the growth process by monitoring the redshift of localized surface plasmon resonance (LSPR). Curiously, the redshift stopped while the chains continued to rearrange as manifested by gradual reduction in the LSPR peak. Using electromagnetic simulations, we quantitatively explained the phenomena as a rapid “addition-polymerization” followed by a sharp transition to “condensation-process.” Next, recognizing the significant electric field enhancement in the interparticle gap, a photoluminescent-active Eu³⁺ ion was used to probe Surface-Enhanced Photoluminescence …
