4-1-2012  Jovan won the 2012 NSF Graduate Research Fellowship (http://www.nsfgrfp.org/). Congratulations.

3-1-2012  Chang-Yong is co-organizing a research symposium entitled "Hierarchically Structured Materials for Energy Conversion and Storage" at the up-coming 2012 Materials Research Society (MRS) Fall Meeting (November 2012). More information on the symposium can be found on the MRS website (http://www.mrs.org/f12-cfp-k/).

1-3-2012  Mingfeng Wang joined as a Postdoctoral Research Associate.  Mingfeng received Ph.D. in Chemistry  from the University of Toronto in 2009 and has been working with Fred Wudl at UCSB as a NSERC Postdoctroal Fellow. In the group, he will study resonant energy cascading in hybrid nanowire solar cells.
  

10-17-2011 After a successful summer internship in the group, Jovan starts as a Undergraduate Research Assistant. He will work on utilizing self-assembled block copolymer nanopatterns for controlled aqueous growth of vertical metal oxide nanowire arrays.  

6-1-2011  Jovan Kamcev joined as a undergraduate summer intern (Department of Energy SULI program). Jovan is from the Stony Brook University (Chemical and Molecular Engineering) and will be working on band gap modification of ZnO nanowire arrays using aqueous transition metal doping.
