Today we say bon voyage to Mrs. Ruth Cochran and her family, and wish them a safe trip as they move Up North. She has been an integral part of this department and is a friend to all who know her. We will all miss her.

Making good on a promise: ionic liquids with genuinely high degrees of thermal stability

New paper from USA Chemistry Department featured on cover of Chemical Communications

Making good on a promise: ionic liquids with genuinely high degrees of
thermal stability by Brooks D. Rabideau,  Kevin N. West  and  James H. Davis, Jr. 

Abstract
"Thermally robust materials have been of interest since the middle of the past century for use as high temperature structural materials, lubricants, heat transfer fluids and other uses where thermal stability is necessary or desirable. More recently, ionic liquids have been described as ‘thermally robust,’ with this moniker often originating from their low volatility rather than their innate stability. As many ionic liquids have vanishingly low vapor pressures, the upper limit of their liquid state is commonly considered to be their degradation temperature, frequently reported from TGA measurements. The short duration ramps often used in TGA experiments can significantly overestimate the temperature at which significant degradation begins to occur when the compounds are held isothermal for even a few hours. Here, we review our recent work, and that of colleagues, in developing thermally robust ionic compounds, primarily perarylphosphonium and perarylsulfonium bistriflimide salts, in some of which cation stability exceeds that of the anion. We have used a combination of molecular design, synthesis, and computational modeling to understand the complex tradeoffs involving thermal stability, low melting point and other desirable physicochemical properties."

Dr. Larry Yet with his new textbook Privileged Structures in Drug Discovery on the Chemistry balcony"Congratulations to Dr. Larry Yet whose book titled, 'Privileged Structures in Drug Discovery:  Medicinal Chemistry and Synthesis' is now in print.  This is Dr. Yet's second book that has gone in print while a faculty member of the Department of Chemistry here at the University of South Alabama.  His first book, which was published just a couple of years ago, was part of the Organic Reactions series which provided a focused, scholarly, and comprehensive overview of olefin ring-closing metathesis reactions.  His latest book in many ways builds upon his first and has as a focus the use of privileged structures as viable candidates in lead optimization stages of drug discovery.  The two books highlight Dr. Yet's expertise as a synthetic organic chemistry whose focus is in the assembly and use of novel scaffolds targeting medicinally important receptors.  " - David Forbes

 

Dr. David Battiste 50 years of service recognition certificate from the ACS"Please join me with the leadership of the American Chemical Society (ACS) in congratulating Dr. David R. Battiste for 50 years of service with ACS. As former/current Chairs of the Local ACS Section - Dr. Stojanovic and I have received these certificates for members in our section over the years who have reached this status and it truly is a pleasure to circulate this to each you. As each of you know Dr. Battiste, I do not need to take any polls in validating our appreciation in all areas of academe to which he has made meaningful and impactful differences to so many (teaching, research, and service). If wanting to see all those recognized for 50 years of service in ACS this year, there are 918, the list was published in C&E News (p. 35) a little over two weeks ago (the March 5, 2018 issue).
