Recent Group Highlights
[See also the group new archives, past and recent past !]
May 2015: Congratulations to Tim Gehan (joint group member with the DV group) for his being awarded one of the four inaugural Manning Inventor fellowships. Tim will receive a $50K fellowship stipend to carry out postdoctoral work for his proposal to develop a practical method for making "PowerStripe" small organic photovoltaic devices by roll-to-roll processing, using method that he developed with the DV group for organic nanoparticle synthesis and film fabrication. Well done, Tim (better write that dissertation fast)! See the UMass news announcement for more information.
April 2015: The group says a fond, "Farewell" to postdoctoral associates Handan Akpinar (left) and Lang Wei (right), who made major contributions to the group's EFRC work. Handan kindly returned to the group spend a postdoctoral year optimizing the synthesis of a new polyarylene vinylene polymer family of structures, and working with physicist Lang (Chinese Academy of Sciences, Beijing) showed it to be successful new photovoltaic active layer material -- a paper is pending for the work. Lang, in addition to her collaboration with Handan, also collaborated with Jeff Lucas (electron microscopy!), Murat Tonga (electron microscopy!), and Jon Tinkham (electron microscopy and solar cell fabrication), for which multiple papers are pending. Physicists and chemists -- what a combination!! In all of the group's history, we never had so many postdoctoral associates (thank you, EFRC), and their hard work and awesome combined talents made for a true powerhouse of excellence!
March 2015: The group says, "Bon voyage!" to postdoctoral associate Supravat Karak and his wife. Supravat had a great three years at UMass, with multiple papers and setting a high standard for applied physics of device fabrication. Supravat was the first person in the group to focus on making electronic devices, and produced both squaraine-based (in collaboration with the Thai group, Andrea Della Pelle, and Paul Homnick) and fluorenylidenemalonoitrile molecule-based solar cells (in collaboration with Paul Homnick), both with very good power conversion efficiencies over 4%. Supravat is giving seminars in India, preliminary to joining Prof. Kunio Awaga's group at Nagoya University to continue his postdoctoral career advancement.
PML visited Waseda University in Tokyo for research and collaborative talks in February 2015, as part of his role participating in Waseda's Energy-Next Leading Graduate Program in Science and Engineering, in which Prof. Hiroyuki Nishide plays a major role. PML thanks Prof. Nishide and Waseda University for supporting the trip, and for the great opportunities to interact with the hard-working and enthusiastic graduate students in Tokyo.
Still pushing the boundaries of research. See the lights burning bright in the early evening at Goessmann 201, before the snows of January 2015 starting burying everything at UMass. Thank you.
Jon Tinkham defended his Ph.D. dissertation with a flourish in January 2015, and has gone west to a postdoctoral position at the National Renewable Energy Laboratory in Colorado. His parting note: "Thanks for all the fish!" (hopefully not prescient in this particular universe).
