Dane placed 3rd in the Fall 2015 PCCM poster night, for his work titled "Synthesis and Characterization of Fluorescently Labeled n-Alkyl Methacrylate Diblock Copolymers". Great job, Dane!
Adam was selected to present in the "Excellence in Graduate Polymer Research" symposium at the American Institute of Chemical Engineers Annual Meeting in Salt Lake City. Quoting from the symposium description: "This is an honorary session consisting of talks by graduate students who have demonstrated excellence in chemical engineering research in any field regarding the area of polymer science and engineering." Adam delivered his talk, "Thermoplastic Elastomers Via Crystallization from Homogeneous Melts" on Tuesday, November 10, to a full room and receptive audience. Congratulations, Adam!
Congratulations to Raleigh, for successfully defending his Ph.D thesis "The Orientation of Microdomains and the Progression of Shear Alignment in Block Copolymer Films: The Roles of Key Material, Film, and Process Parameters".
The group welcomes Beomgoo Kang as our new post-doctoral researcher! Beomgoo comes to the Register lab from Jimmy Mays' group at the University of Tennessee, where he worked on a wide range of copolymer chemistries and archirectures via anionic polymerization.
In work described as a "major breakthrough" by the peer-reviewers, Dong-Gyun Kim's article "Hydroxyhexafluoroisopropylnorbornene Block and Random Copolymers via Vinyl Addition Polymerization and Their Application as Biobutanol Pervaporation Membranes", was published in the October 13 issue of Chemistry of Materials. The result of a collaboration with researchers from Promerus LLC, this paper describes synthesis and performance characterization of new block and random copolymers, which are exceptionally well-suited to the recovery of n-butanol from dilute aqueous solutions, such as fermentation broth. This article was selected for the ACS Editors' Choice program, meaning that it will be open access (freely available to the general public) in perpetuity, so the link above will provide access to the article with or without a Chemistry of Materials subscription. Only one article per day, across all ACS journals, is selected as Editors' Choice, making this distinction more selective than being chosen for the journal cover. Congratulations, Dong-Gyun!
Raleigh made the trek down to Alpharetta Georgia to begin his new career with Solvay Advanced Polymers LLC. Raleigh will return to Princeton in the Autumn to defend his thesis, but until then the group wishes him a great start as he begins the next chapter of his professional life!
