Like previous years, we are soliciting questions from attendees ahead of the meeting so that we can pass them off to our speakers to answer either during their talks or during an open panel discussion. If you have questions for one of our panelists or just in general, email Dr. Ayse Asatekin (ayse.asatekin@tufts.edu) or Dr. Manish Kumar (manish.kumar@psu.edu) and we will answer them during the workshop.

Also, please bring your resume/CV as our speakers will be able to provide critiques during a breakout session. Both graduate students and undergraduate students are welcome to attend.

   Membrane Workshops

   Saturday, May 21, 8:00 AM

Workshop 1: Measurement Methods for Membranes

    John Pellegrino, University of Colorado at Boulder
    Ruth Baltus, Clarkson University

This workshop provides an overview of the entire field of membrane science, technology, and applications through measurements, and is therefore an excellent resource for novices with a technical background, as well as, seasoned veterans interested in broadening their scope (or having a refresher.) The workshop will provide a survey of the various physical and chemical properties of membranes (and membrane process characteristics) that are measured, and the equipment (instruments) and techniques used, along with their underlying principles. A mixture of classical, novel, and resource-intensive techniques are included.
  • Two weeks prior to the workshop a set of journal articles will be made available to registrants through a Google (or other) Cloud drive. These articles will be used in active learning segments of the class utilizing concept questions.
  • One week prior to the workshop all registrants will be asked to fill out a survey with questions and topics of particular interest to them. We will strive to make sure that these items are discussed.

Syllabus topics include:
  • Introduction to membranes: review of membrane types and structures; goals of measurements; broad perspective on trade-offs and opportunities in characterization
  • Overview of transport processes and figures-of-merit: flux, selectivity, rejection, sieving coefficient; simple geometric membrane models
  • Membrane materials and polymers; density and fractional free volume; thermal and mechanical analysis - differential scanning calorimetry, dynamic mechanical analysis, thermal relaxation, nanoindentation; dielectric relaxation
  • Metrology basics: metrology basics and uncertainty; measuring density-pyncnometry; solubility-sorption pyncnometry, gravimetric, SAW, QCM, TGA, calorimetry
  • Gas and vapor systems: measuring time lag for permeation; mass spectrometry-transient permeation
  • Liquid systems testing: calibrations; permeation; species fractionation; integrity
  • Porometry
  • Surface and chemical measurements: surface energy and charge; FTIR; surface chemical analysis - XPS, Auger, SIMS, RAMAN, NMR, MRI, MALDI-TOF
  • Visualization and scattering:
  • Other topics and motivations: (for example, ultrasonics, electrochemical, TIRF, etc.)

    Workshop 2: Membranes for Water Treatment

    Isabel Escobar, University of Kentucky
    Dibakar Bhattacharyya, University of Kentucky
    Ben Weaver, Nanostone Water Inc.

Membrane processes are finding wide applications ranging from water treatment to reactors to advanced bio-separations. Membranes are particularly useful for material recovery and for permeate reuse (such as, water recycle). The workshop is configured as a one day program of about 6 hours of lectures. Both desalination and toxic pollutant removal/destruction techniques will be discussed. The workshop topics include membrane selection criteria, practical information regarding configuration, performance and operating conditions of membrane technology applied to desalination of brackish and seawater, and wastewater reclamation systems, mixed-matrix membranes, and advanced functionalized/responsive membranes from toxic metal capture to water detoxification. Membrane surface and pore functionalization approaches, reactive nanostructured for water detoxification will be part of the advanced membrane topics. The effects of feed water quality, pretreatment options, operating parameters and performance of membrane units and hybrid options will also be discussed. The workshop material will also include information on economics of membrane systems including drivers for membrane selection for various applications.

   Workshop 4: Polymer Ion-Exchange Membranes for Electrochemical Applications

    Yushan Yan, University of Delaware
    Corky Mittelsteadt, Giner Inc.

Polymer ion-exchange membranes (IEMs), including proton exchange membranes (PEMs) and hydroxide exchange membranes (HEMs), have important applications in electrochemical energy conversion devices including fuel cells (FCs), electrolyzers (ELs) and redox flow batteries (RFBs). IEMs share the basic structure of polymer backbone with an ionic group either in the backbone or tethered to the backbone via a pendent side chain. In the case of PEMs an anion such as -SO3- is attached while for HEMs, the anion is replaced by a cation such as -N(CH3)+. These ionic groups in general facilitate the transport of ions of the opposite charge, while exclude ions of similar charge. The history, development and applications of IEMs are presented, as well as the critical physical properties for different applications with an emphasis on characterization. We also look at the lifetime of IEMs in different applications, and how they generally fail.
The synthetic pathways of manufacturing IEMs are discussed, as well as structure/property relationships and challenges for both PEMs and HEMs. As of today PEMs are much more advanced than HEMs due to their more mature synthesis, and greater durability. We will begin by introducing PEMs and then move on to HEMs.
