Description:About the Seminar\n\nThe interface between two fluids is not on
 ly important for defining reactivity of dislike materials\, but is also ap
 plicable for the preparation of stable higher order structures. Recently\,
  the Pentzer lab developed 2D carbon-based nanosheets that assemble at dif
 ferent fluid-fluid interfaces including oil-water\, oil-oil\, and ionic li
 quid-water and demonstrated the use of these Pickering emulsions as templa
 tes for the preparation of higher order hybrid structures. Graphene oxide 
 (GO) and its functionalized analogues are used as the 2D particle surfacta
 nt\, and are especially attractive given they have properties distinct and
  complimentary to the more commonly studied spherical and rod-like counter
 parts\, and because these nanosheets are multifunctional (e.g.\, antimicro
 bial\, good gas barriers\, precursor to electrically conductive nanosheets
 \, etc.).  Recent advances from the Pentzer lab will be reported\, includ
 ing preparation of Janus nanosheets\, water-sensitive reactions in oil-in-
 oil emulsions\, GO capsules filled with ionic liquid for supercapacitor el
 ectrodes\, GO capsules for compartmentalization of phase change materials\
 , and GO coatings for 3D printable polymers to prepare conductive structur
 es. This work makes use of fundamental organic chemistry reactions and thu
 s gives access to unique structures and assemblies of interest for a broad
  range of applications in a scalable fashion.\n\nAbout the Speaker\n\nEmil
 y Pentzer is the Frank Hovorka Assistant Professor of Chemistry at Case We
 stern Reserve University in Cleveland\, OH. She received a BS in chemistry
  from Butler University (2005) and PhD in organic chemistry from Northwest
 ern University (2010)\, where her thesis work focused on metathesis routes
  for preparing and polymerizing unsaturated medium-sized lactones and lact
 ams under the direction of Professor Sonbinh T. Nguyen. She then worked wi
 th Professor Todd Emrick in the Polymer Science and Engineering Department
  at UMass Amherst where she focused on the synthesis and assembly of elect
 ronically active materials for organic photovoltaics as part of a DOE EFRC
  on Polymer-Based Materials for Harvesting Solar Energy. In 2013\, Dr. Pen
 tzer joined the faculty at CWRU in chemistry and received a secondary appo
 intment in Macromolecular Science and Engineering in 2015. Her research us
 es organic synthesis to access new materials and assemblies as a route to 
 understand structure-property relationships and access electronic properti
 es not possible with current state-of-the-art systems. Dr. Pentzer has rec
 eived several awards including the NSF-CAREER award (2016) and PMSE Young 
 Investigator Award (2017). She currently serves as an Associate Editor for
  the RSC journal Polymer Chemistry as well as the publicity chair for the 
 Polymer Division (POLY) of the American Chemical Society.\n\n&nbsp\; 4:00
