of infrared light. Shujing Wang and postdoctoral fellow Marat Khafizov finally succeed in generating multiple electrons from a single photon of light in carbon nanotubes! Someday this “buy one get one free” type process may allow for more efficient solar cells. Also, Amy Ensign, Dr. Andrea Lee and Wesley Asher, all co-advised by Prof. Kara Bren, together had great fun exploring various aspects of protein folding on the single particle level.

Helen Wei spent last year trying to make large batches of the “special” nonblinking quantum dots with potential for vastly improved lasers and optical amplifiers, while Jenneke Jalink was working hard to make vertically aligned carbon nanotube arrays with potential relevance for the production of hydrogen from solar energy. Julie Smyder dove deep into the fluorescence of single clusters of semiconductor nanoparticles that are less than 100 atoms total, while Jack Calcines spent the better part of last year discovering a new way to grow elongated semiconductor nanoparticles called quantum rods with the highest aspect ratio reported to date for this chemical system. Jack and Julie should have their contributions in print very soon – congratulations! The group is delighted to have added a couple of new students to the mix: Fen Qiu and Brad Loesch who are working in the nano- crystal and nanotube areas, respectively, as they get going.

During the summer the group hosted two undergraduates from the University of Rochester: Matt McKay and Don Polaski. They have been with the group through the entire year and are enjoying not taking any hard UR classes so they can focus fully on research.

Finally, Todd was pleasantly very busy this year between a new graduate course on the electronic properties of molecules to ma- terials and writing up several “important” results coming from the hard work of the group. However, he still found time to or- ganize the first University conference on nanomaterials, “Nano- Symposium 2009”, which was great fun for those who attended.

Professor Emeritus of Chemistry

Ph.D. 1964, Washington University

RESEARCH INTERESTS New experimental and theoretical techniques to study molecular structure and electronic properties of transition metal complexes and paramagnetic organic molecules; and mea- surement of electron transfer rates between molecules held in polymers.

ROBERT KREILICK is enjoying his second year as Professor Emeritus of Chemistry. Professor Kreilick’s research involves investigations of magnetic and electrical properties of solid transition metal complexes and organic free radicals. Experi- ments which produce information about electron-electron exchange interactions, dipolar interactions, and electrical con- ductivity are conducted. Last year, new software was written for the ESR spectrometer and low temperature equipment was brought back into working order. We now have an ESR center which is being used by other chemistry faculty members.
