Work Presented at Kavli Highlighted in Science

Upcoming work which Will presented during his Kavli lecture at the 250th ACS National Meeting in Boston, MA was highlighted in Science. The article entitled “New electric storage material could put more zip in your Tesla” overviews how Catherine DeBlase achieved further improvement of our energy storage devices by forming a nano-composite of our redox-active COF with a conductive polymer.

Dichtel Group Presents Research at Boston ACS

Ten students and postdocs presented their work at the recent 250th ACS National Meeting in Boston. Will delivered the Kavli Foundation Emerging Leader in Chemistry Lecture. His lecture, “The Spectacular Properties of Porous Polymers,” described how to design permanent porosity into polymers and how these high surface area materials might be useful for applications in water purification and energy storage. His concluding remarks were controversial.

JAC KLW Graduate Summa Cum Laude

Jackie Carozza and Katherine Walker graduate summa cum laude!

Congratulations to undergraduates Jackie and Katherine for their academic achievements at Cornell and within the group! We wish them the best as they embark on graduate studies at Cambridge and Stanford, respectively.
