This reaction is used in an introductory organic chemistry course to illustrate principles of gas-liquid chromatography, geometrical isomerism, homogeneous catalysis, and activation energy determinations. (BB)

Provides eight physics experiments, demonstrations, and activities relating to radioactive decay, computers, semiconductors, and electronics. (SL)

Describes a computer simulation to elucidate the subject of coherence. The model on which simulation is based links coherence to the correlation of fields. It also describes the model and presents some results. (Author/GA)

Ethylene hydrogenation on a platinum catalyst, electrolytically applied to a tube wall, is a good system for the study of the interactions between diffusion and surface reaction in heterogeneous catalysis. Theoretical background, apparatus, procedure, and student performance of this experiment are discussed. (BB)

Presents simple and inexpensive demonstrations of properties of metallic glasses. (SL)

Using the simple optical system and photodiode described in this article it is possible to give clear, quantitative demonstrations of all the Fraunhofer diffraction phenomena at single and multiple apertures. These measurements can be related to the theoretical predictions given in standard textbooks. Circuit diagram and optical layout are…
