Centrifuging a Sample  John W. Moore, Jerrold J. Jacobsen, Lois M. Browne, John F. Zimmerman
The demonstration on this page shows a technique that should not be used by undergraduate chemistry laboratory. This video shows what happens to sample in a centrifuge while the centrifuge is on, and the result of stopping the centrifuge improperly. A narrative is included in this video: The centrifuging process allows the solvent to completely settle out. The jarring caused by hand braking destroys the distinct separation between supernatant and solid.

Study of Molecular-Shape Selectivity of Zeolites by Gas Chromatography  Pei-Yu Chao, Yao-Yuan Chuang, Grace Hsiuying Ho, Shiow-Huey Chuang, Tseng-Chang Tsai, Chi-Young Lee, Shang-Tien Tsai, and Jun-Fu Huang
This analytical or physical chemistry sorption experiment uses hexane isomers as probe molecules to demonstrate the "molecular-shape selectivity" behavior of zeolites. Students can also modify the sorption protocol to build their own experiments.

Percy Julian, Robert Robinson, and the Identity of Eserethole  Addison Ault
The Nova production Percy JulianForgotten Genius, which included the very public disagreement over the identity of "eserethole," the key intermediate for the synthesis of the alkaloid physostigmine, left three important chemical questions unanswered.

Mechanisms That Interchange Axial and Equatorial Atoms in Fluxional Processes  Marion E. Cass, Henry S. Rzepa, King Kuok Hii
The Berry pseudorotation is a classical mechanism for interchanging axial and equatorial ligands in molecules with trigonal bipyramidal geometry. Teaching this mechanism presents particular pedagogic problems due to both its dynamic and three dimensional character. The approach taken here illustrates these processes using interactive animations embedded in a Web page and overcomes many limitations of a printed page.
