    • A small amount of vaterite was always formed, but this is consistent with the control experiments in the absence of gel that also contained some vaterite spherulites (see ref. 28).

    • note
    • Interestingly, the vaterite crystals obtained in early experiments with low calcium concentrations also appear to have etch pits.

    • note
    • Calculations of the approximate amount of calcium consumed by crystal growth after 7.5 hours (when the etch pits begin appearing) indicate that there is sufficient (orders of magnitude) calcium remaining to satisfy the gelator.

    • A solution of 1 with no added counteraction does not form a gel and is stable on the benchtop for up to a week before becoming viscous (L.A. Estroff, PhD. Thesis, Yale University, New Haven, 2003).

    • 3 crystal (average size from microscopy) contains 0.03 pmoles of 1. This is approximately 0.1 wt% which is too small to be detected by many methods.

    • According to an equation derived by Correns, this depends on the supersaturation and molar volume of the crystallizing compound. C. W. Correns, Faraday Discuss., 1949, 5, 267.

    • 2+ calcite, which has a higher solubility than pure calcite. The overgrowth was pure calcite, suggesting that this may just be an example of Ostwald rippening, see ref. 37.
