Förster, Christoph; Heinze, Katja – Journal of Chemical Education, 2020
Instructive, inexpensive, and environmentally friendly laboratory syntheses of two highly luminescent copper(I) complexes CuI(PPh[subcript 3])[subscript 2](py[superscript R]) (py[superscript R] = pyridine, 4-cyanopyridine) are described for second-year/upper-division undergraduate inorganic chemistry students. Both complexes exhibit bright…

de Izarra, Charles; Gitton, Jean-Michel – European Journal of Physics, 2010
The goal of this work proposed for undergraduate students and teachers is the calibration of a tungsten filament lamp from electric measurements that are both simple and precise, allowing to determine the temperature of tungsten filament as a function of the current intensity. This calibration procedure was first applied to a conventional filament…
