Read the article entitled "Oriented Growth of Calcite Controlled by Self-Assembled Monolayers of Functionalized Alkanethiols Supported on Gold and Silver" by J. Aizenberg, A. J. Black, and G. M. Whitesides (J. Am. Chem. Soc., 1999, 121, 4500-4509) and answer the following questions. What is a self-assembled monolayer? What interactions promote the self-assembly? What interactions promote binding of the alkanethiol to the Ag or Au substrate? What interactions are responsible for binding the calcite to the alkanethiol? Why do some alkanethiols promote crystal formation and others do not? Why is there orientation control of the crystal formation?
