    BLUE HEN CHEMIST University of Delaware, Department of Chemistry and Biochemistry Annual Alumni Newsletter NUMBER 41 AUGUST 2014 JOHN L. BURMEISTER, EDITOR ON THE COVER THREE Newly Renovated Organic Laboratories! # 3 8 - P AGE I BLU E H E N C H E MIST ON THE COVER One of the three newly-renovated Organic Chemistry teaching laboratories (QDH 302) is shown. Work on the labs (QDH 112, 318, 320) started on May, 2013 and was completed in February of this year. The refurbishment of the labs was a crucial step in the ongoing revision of the Organic Chemistry laboratory curricula. The additional fume hoods allow each student to conduct experiments individually while minimizing their exposure to chemical reagents. The transparent glass construction helps teaching assistants observe students while they work. The hoods are equipped with inert-gas lines, which can allow the students to work with air-sensitive compounds and learn advanced laboratory techniques. The hoods are also equipped with vacuum lines, which obviate the need for water aspirators and dramatically reduce the labs' water usage. The lab design also allows for instrumentation modules to be swapped in and out according to the needs of the experiment. Carts are designed to house instruments such as gas chromatographs and infrared spectrometers as well as any necessary computer equipment. These carts can then be wheeled into docking areas that have been fitted with the necessary inert gas and electrical lines. The design expands the range of possible instrumentation the students can use while occupying a small footprint of lab space. The labs also feature large flat screen monitors, wireless internet, and computer connectivitiy that will enable the use of multimedia demonstrations and tablet computing.

  • Creative Destruction? Cases of Defence Conversion in the United States
    Defence Sites II 399 Creative destruction? Cases of defence conversion in the United States C. Preble Defense and Foreign Policy Studies, The Cato Institute, USA Abstract Politicians often claim that the closure of military facilities will do irreparable harm to local economies. Such predictions can be refuted by empirical data, and by studying actual cases of defence conversion in the United States. This paper considers the economic impact of the closure, and subsequent redevelopment efforts, of three facilities: Bergstrom Air Force Base in Austin, Texas; DuPont’s Eleutherian Mills in Wilmington, Delaware; and the Brooklyn Navy Yard in New York. It is reasonable to infer from this research, when combined with aggregate empirical data, that defence conversion often generates greater economic activity than prevailed before the closures. Keywords: defence economics, Brooklyn Navy Yard, Bergstrom Air Force Base, Eleutherian Mills, Hagley, DuPont. 1 Introduction Industry leaders and politicians regularly claim that the closure of military facilities will do irreparable harm to local economies. Such predictions of certain calamity can be refuted by empirical data, and by a careful study of actual cases of defence conversion. In general, there are clear societal and economic benefits associated with moving resources from the military to more productive industry sectors, and to civilian uses. We take such resource shifts for granted in the private sector, when changing consumer tastes and new technologies cause some businesses to fail while others thrive. But politics and parochialism often intrude when military needs change. Instead of imagining the jobs lost when military bases close, or when military manufacturers relocate or retool, this paper will present several cases of defence conversion in the United States from the 19th, 20th, and 21st centuries.
