Saïd Sadki, from the University Grenoble Alpes and CEA-Grenoble, shared his research in a Polymer Seminar Series talk (“Bottom-Up conjugated/conducting polymers-coated Silicon Nanostructures for Integrated On-chip EDLCs and Batteries”; January 18, 2019). This was an exciting finale to a week of intense research discussion and student mentorship during which Penn’s REACT team hosted its international partners in Philadelphia for activities including the 2019 REACT@Penn Symposium.
