The Electrochemical Synthesis of Transition-Metal AcetylacetonatesS. R. Long, S. R. Browning, and J. J. Lagowski The electrochemical synthesis of transition-metal acetylacetonates can assist in the transformation of an entry-level laboratory course into a research-like environment where all members of a class are working on the same problem, but each student has a personal responsibility for the synthesis and characterization of a specific compound. Long, S. R.; Browning, S. R.; Lagowski, J. J. J. Chem. Educ.2008, 85, 1429.

Using Metals To Change the Colors of Natural DyesJennifer E. Mihalick and Kathleen M. Donnelly Metal salts (mordants) are used to produce different colors in fabrics dyed with tea leaves or marigold flowers. This experiment is especially suitable for nonscience majors and can be used to introduce polymers. Mihalick, Jennifer E.; Donnelly, Kathleen M. J. Chem. Educ.2006, 83, 1550.

Demonstrating and Measuring Relative Molar Magnetic Susceptibility Using a Neodymium MagnetCharles J. Malerich and Patrica K. Ruff A method for demonstrating and measuring the magnetic attraction between a paramagnetic substance and a neodymium magnet is described and evaluated. The experiment measures the maximum angle that the magnet can deflect a paramagnetic compound from the vertical. The apparatus to make this measurement is easy to set up and is low-cost. Malerich, Charles J.; Ruff, Patrica K. J. Chem. Educ.2004, 81, 1155.

Photosystem II Oxygen-Evolving ComplexWilliam F. Coleman Both introductory texts and texts for upper-level inorganic chemistry courses are shifting the emphasis in their coverage of transition metal chemistry from classical Werner complexes to those that exhibit some form of catalytic activity. This is of particular importance to bioinorganic chemistry, a now mature area of the science, but one that is still underrepresented in the undergraduate curriculum. Derrick L. Howard, Arthur D. Tinoco, Gary W. Brudvig, John S. Vrettos, and Bertha Connie Allen address this issue in their paper Catalytic Oxygen Evolution by a Bioinorganic Model of the Photosystem II Oxygen-Evolving Complex by a dimanganese complex that is proposed as a model for the four-manganese center in Photosystem II. The featured molecules for May are the model compound in the proposed mechanism for oxygen production.
