Nicolas J. Alvarez is a Professor of Chemical and Biological Engineering at Drexel University. Alvarez received his PhD from Carnegie Mellon University specializing in the area of surfactant transport phenomena at fluid-fluid interfaces with Lynn Walker and Shelley Anna. Prior to joining the faculty at Drexel, Alvarez studied polymer physics and dynamics as a researcher at the Technical University of Denmark with Ole Hassager. During this time, Alvarez developed the first table top filament stretching rheometer, which has since been patented and is available commercially through his co-founded company Rheo Filament ApS. He is the recipient of several awards acknowledging his contributions to the field of extensional rheology and colloid science.

Course Description

This short course will provide an extensive (pun intended) introduction to both theoretical and experimental aspects of extensional rheology ranging from dilute polymer solutions to melts. Emphasis will be placed on establishing a solid foundation in the various extensional rheology techniques. The primary aim is to enable attendees to determine which measurements are appropriate for a given sample, conduct their own extensional measurements, critically assess and analyze experimental data, interpret experimental data in the framework of polymer physics, and apply these principles and practices in development of novel approaches in academic research and/or industrial practice. On Day Two, participants will gain hands on experience with state-of-the-art equipment. The attendees will analyze experimental data to illustrate theoretical concepts covered in the lectures. Focus will also be placed on new emerging topics in extensional rheology including supramolecular (associating) polymers and microfluidic techniques.

Course Outline

Saturday (Day One)

  • Introduction to Extension
  • Dilute Polymer Solutions
  • Concentrated Polymer Solutions to Melts
  • Melts and Elastomers

Sunday (Day Two)

  • Complex Materials and Supramolecular (Associating) Polymers
  • Relating Extensional Rheology and Processing
  • Techniques for Sample Preparation
  • Experimental Hands-on and Data Analysis
