Walsh, Emma L.; Ashe, Siobhan; Walsh, John J. – Journal of Chemical Education, 2012
The purpose of this experiment is to provide students with the essential skills and knowledge required to perform the extraction, isolation, and structural elucidation of parthenolide from "Tanacetum parthenium" or feverfew. Students are introduced to a background of the traditional medicinal uses of parthenolide, while more modern applications of…

Carroll, Anne-Marie; Kavanagh, David J.; McGovern, Fiona P.; Reilly, Joe W.; Walsh, John J. – Journal of Chemical Education, 2012
Nature is a well-recognized source of compounds of interest, but access is often an issue. One pertinent example is the cinchona alkaloids from the bark of "Cinchona calisaya." In this experiment, students at the third-year undergraduate level undertake the selective isolation and characterization of two of the four main alkaloids present in the…

Surpless, Benjamin; Bushey, Michelle; Halx, Mark – Journal of Geoscience Education, 2014
Although science educators at all levels have focused on teaching students scientific literacy for nearly five decades, studies indicate that the average student remains far from scientifically literate. To address this issue at the local level, faculty at Trinity University, in San Antonio, Texas, significantly revised the curriculum of an…

Liao, Wenjing – ProQuest LLC, 2013
This dissertation is composed of two parts. In the first part techniques of band exclusion(BE) and local optimization(LO) are proposed to solve linear continuum inverse problems independently of the grid spacing. The second part is devoted to the Fourier phase retrieval problem. Many situations in optics, medical imaging and signal processing call…
