Varberg, Thomas D.; Skakuj, Kacper – Journal of Chemical Education, 2015
Here we describe an experiment for the undergraduate physical chemistry laboratory in which students synthesize the intermetallic compounds AlNi and AlNi3 and study them by X-ray diffractometry. The compounds are synthesized in a simple one-step reaction occurring in the solid state. Powder X-ray diffractograms are recorded for the two compounds…

Hein, Sara M.; Kopitzke, Robert W.; Nalli, Thomas W.; Esselman, Brian J.; Hill, Nicholas J. – Journal of Chemical Education, 2015
A discovery-based Grignard experiment for a second-year undergraduate organic chemistry course is described. The exclusive Grignard reagent formed by the reaction of 1-bromo-4-fluorobenzene (1) with Mg is 4-fluorophenylmagnesium bromide (2), which is treated with either benzophenone or CO[subscript 2] to produce the corresponding fluorinated…

Dounas-Frazer, Dimitri R.; Stanley, Jacob T.; Lewandowski, H. J. – Physical Review Physics Education Research, 2017
We investigate students' sense of ownership of multiweek final projects in an upper-division optics lab course. Using a multiple case study approach, we describe three student projects in detail. Within-case analyses focused on identifying key issues in each project, and constructing chronological descriptions of those events. Cross-case analysis…
