On Thursday, June 25 at 10 a.m. in 104 Textile Engineering Building, the Department of Polymer and Fiber Engineering will host a seminar featuring Gerardo Callegari, staff scientist at TRI Princeton. Callegari will present "Absorption of Droplets by Fibrous Materials," which discusses experimental data and theoretical approaches to the absorption and spreading processes of liquid droplets into fibrous materials.

Callegari will identify applications to these approaches, such as ink-jet printing and the interaction between a fibrous substrate and a liquid, as well as the transport properties of deformable porous materials and structural modification of fibrous materials. Callegari will also demonstrate the absorption of highly elastic bio-liquids in elasto-inertial absorption regimes in single pores.

Callegari received his doctoral degree in physics from Buenos Aires University in Argentina. His research interests include interfacial phenomena and characterization of the transport properties of porous materials and micro-fluidics. He is currently the chair and one of two main lecturers of a course entitled "Interaction of Liquids with Porous Materials" at TRI Princeton. TRI Princeton has provided advanced research and education in polymers, fibers, films, human hair and porous materials for more than seven decades.
