 Earlier news: 

In August '08,  after returning from the student exchange trip to Japan,  Jason Diaz  presented a poster on our organometallics project  at the 236 National ACS meeting in Philadelphia (very conveniently it was not too far from home for Jason)

July '08:  Anna participated in the International Congress on Coordination Chemistry in July 2008 with a poster presentation. great conference. Way too hot in Jerusalem in July!

Our recently published paper on orthocarborane-based  ionic liquids coauthored by Jesse Kleingardner('07), Ryan Wibby('08) , John Dymon ('10) and Anna Larsen (with collaborators from Queen's University, Vassar College and University of Wisconsin-Madison) made it to the top ten list of the most accessed papers for the month of May 2008 in Dalton Transactions, the leading European journal for inorganic and organometallic chemistry: 

The full citation: Dalton Trans., 2008, 2999 - 3006, DOI: 10.1039/b802374c 

June 23-2008: Differential Scanning Calorimetery  and Thermal Gravimetric Analysis instruments are here and working. Shawn Eady ('10) is busy running our samples on both! 

 july-10-2008:  John Dymon is in Australia apparently having great time in and out of the lab.   He is learning Electrochemistry of Ionic Melts with our collaborator Maria Forsyth research group in Monash University.  We will be sending more samples of the low-melting salts to John shortly. 

April'08:  The revised Pt manuscript was accepted for publication in Canadian Journal of Chemistry.

April '08: John Dymon has received IC Dana summer internship to support his trip to Australia!   Way to go visit kangaroos  and do some electrochemistry in the spare time.

Anna gave an invited lecture at the SUNY-Albany chemistry Department on April 15th. Very useful feedback was an extra-bonus of the trip.

We just heard that Ithaca college will fund the purchase of our own Differential Scanning Calorimeter and Thermogravimetric Analyzer (~40K).  No more trips (and no more paying!) to Cornell U for that.

Congratulations to Cole Lechlieter ('10) who was awarded special ACS PRF summer scholarship for research on our organometallics project.   

In spite of serious case of  senioritus,  Phil Byers ('08)  is still planning to graduate this spring!! (and off to grad school in Florida State....)
