Seminar 9/17/2014 - David Hoagland, University of Massachusetts-Amherst: Polymers, Proteins, and Particles in Ionic Liquids

Sep 17, 2014  ·  12:00 p.m. 1:00 p.m.  ·  Bowen Hall Auditorium

Abstract: Ionic liquids, defined as salts that melt near or below room temperature, present attractive solvent properties for soft matter systems, as will be discussed for (i) neutral, charged, zwitterionic, and crystallizable polymers, (ii) enzymatic proteins, and (iii) dispersed nanoparticles. One characteristic property, nonvolatility, enables the application of high vacuum methods such as electron microscopy to highly solvated, and thus highly dynamic, systems.  Here, electron microscopy methods that visualize ‘wet’ samples are described, taking as a model case the movements and interactions of nanoparticles; unusual thin film effects are uncovered. Ionic liquids also display striking solvency properties, as outlined for polyelectrolytes, polyzwitterions, and proteins. For the last of these, neat ionic liquids afford solvent environments distinct from aqueous electrolytes, preserving most, but not all, elements of structure and activity.

Bio: Hoagland is Professor and Head of the Polymer Science and Engineering Department at the University of Massachusetts Amherst. He has been in the same department since beginning his independent academic career in 1985.  Undergraduate and graduate degrees in Chemical Engineering are from Stanford and Princeton, respectively. Hoagland’s research focuses on structure and dynamics in soft polymeric systems such as gels and solutions, with current projects in ionic liquids, carbon nanotube assembly, and protein coacervation.

Seminar 10/22/2014 - Dean DeLongchamp, NIST: Structure Measurements for Organic Photovoltaics and Manufacturing

Oct 22, 2014  ·  12:00 p.m. 1:00 p.m.  ·  Bowen Hall Auditorium

Abstract: Organic photovoltaics (OPV) is a promising candidate technology for the low-cost fabrication of modules to harvest solar energy.  Although OPV technology has significantly matured over the past few years, there remain significant challenges in addressing the gap between lab-scale devices and real manufacturing. Structure-property-performance relationships for OPV devices are still underdeveloped, and relationships based on one system are not necessarily transferrable to new, higher-performance systems. This talk will describe our efforts to develop measurements that support OPV manufacturing. Using a blade coating process as a prototype for slot-die coating, we have developed several techniques to observe the structure of OPV films in-situ as they dry. Our measurements include synchrotron-based X-ray scattering and a variety of optical methods. We use these techniques to identify the mechanisms by which formulation and processing choices influence the nanoscale structure of the films. Several OPV systems will be described including polymer/fullerene, small-molecule/fullerene, and polymer/polymer. Throughout solidification, we can follow the number of phases, their composition, and the extent of order within them. In-situ techniques provide far more information about the solidification process than can be obtained by measuring already-dried films, providing a valuable tool to guide the selection of formulation and processing parameters.
