Alexa Kuentsler, our summer REU, heads back to Rochester (August 2013)
Our REU student, Alexa Kuenstler, studied the effect of electric fields on the orientation of morphology in ion-containing block copolymers. Orienting the ion-conducting domains in the direction of ion transport may enhance the conductive properties and further our understanding of how ions move in nanostructured ion-containing block copolymers. Alexa used an in-house electric field alignment device to perform alignment experiments and studied the morphology of oriented block copolymer samples using scanning electron microscopy (SEM).
Alexa was wonderful to work with and we wish her all the best in her junior year at the University of Rochester!
Winey Group members Francisco Buitrago and Rose Mutiso successfully defended their dissertations on July 10 and 18 respectively!
Francisco investigated the morphology-property relationships of precisely sequenced ionomers while Rose worked on electrical properties in nanowire systems. Their work has significantly furthered our group’s knowledge and expertise in these areas and we are thrilled at their success!
Congratulations Drs. Buitrago and Mutiso!

The third Philly Materials Day was held on Saturday, February 2, 2013. This is a popular outreach activity for the group as members all enjoy sharing fun science with a young and receptive audience.
Several Penn Faculty and students turned out to share their love of science with the enquiring young visitors. Group Members Sharon Wang and Steve Szewczyk and five captivated young participants observed the behavior of different polymer bouncy balls: one stores energy more effectively and bounces, while the other loses energy to sound/heat.
In the afternoon Dr. Winey and her audience pondered the question: Can We Make Plastics into Metals?
On January 8, 2013, the Nanotechnology Institute (NTI) in partnership with the University of Pennsylvania hosted a workshop on Facilities for Nanotechnology in the Philadelphia area. The workshop highlighted the facilities and expertise in nanofabrication and nanoscale characterization that are available to external users at the University of Pennsylvania. The event also provided a platform to promote the new PA RapidNanoNetTM funding opportunity that is co-sponsored by the NTI.
We welcomed 37 industry participants representing over twenty companies ranging in size and complexity from small start-ups to large international companies. The program included talks by Penn faculty and staff involved in nanotechnology research and tours of the facilities. One of the highlights of the day was a tour of the new Krishna P. Singh Center for Nanotechnology due to open later this year.
We are delighted to announce that group member Jae-Hong Choi successfully defended his doctoral thesis on Wednesday, September 19th, 2012! Jae-Hong’s work involved morphology studies of new polymerized ionic liquid block copolymers to further our understanding of the mechanism of ion conduction. He will be leaving in October to join Professor Tim Lodge’s research group at the University of Minnesota.
Congratulations Dr. Choi!
Great job Katie! REU (Summer 2012)
