    American Mineralogist, Volume 88, pages 947–948, 2003 Acceptance of the Dana Medal of the Mineralogical Society of America for 2002 MICHAEL F. HOCHELLA JR. Nanogeoscience and Technology Laboratory, Department of Geological Sciences, Virginia Tech, Blacksburg, Virginia 24061, U.S.A. I read several years ago about a Noble Laureate in chemis- try who was being interviewed by a reporter. He was asked what it takes to win a Noble Prize. Without hesitation, the chem- ist said that it took three things. First, being a genius was defi- nitely not required. Being reasonably intelligent was perfectly fine. Second, you needed to be a hard worker. (I remember thinking at that point in reading this story that the great major- ity of all successful scientists that I have ever known have ful- filled these two criteria. What then was the third, and presumably deciding factor, which resulted in winning a Nobel Prize. I read on anxiously.) Third, you not only had to be at the right place at the right time, but you had to be very, very fortu- nate! Indeed. And that is why I never even gave serious thought to winning a science prize of any sort. Not to mention that I have been accused in the past of being a dilettante geochemist. That comment must have had some element of truth because it struck a nerve. The proper response to that kind of comment is, FIGURE 1.

Gaithersburg Marriott Washingtonian Center Gaithersburg, MD June 5-6, 2005 FORWARD “Analytical and Isotopic Geochemistry” is the twelfth in a series of Geosciences Research Program Symposia dating from 1995. These symposia are topically focused meetings for principal investigators in the program and provide opportunities for our investigators to give presentations on their Office of Basic Energy Sciences’ supported research. In addition to the recognition the symposium gives to all of the investigators, we traditionally also recognize one outstanding contribution from a DOE Laboratory Project and one from a University Project. The outstanding contributions are selected by our session chairpersons. We are fortunate to have as guest session co-chairs Professor William McDonough from the University of Maryland at College Park, Professor Joel Blum from the University of Michigan, Professor John Hanchar from the Memorial University of Newfoundland and Professor Louis Derry from Cornell University. They join our Principal Investigator co-chairs Professor Patricia Dove of Virginia Tech, Professor R. James Kirkpatrick from the University of Illinois, Professor Satish Myneni from Princeton University and Dr. Jeffrey Seewald from Woods Hole Oceanographic Institution. For their efforts on behalf of the investigators I thank them all. We are looking forward to an outstanding series of presentations. Nicholas B.

  • Nanoscale Effects of Strontium on Calcite Growth: a Baseline for Understanding Biomineralization in the Absence of Vital Effects
    Nanoscale Effects of Strontium on Calcite Growth: A Baseline for Understanding Biomineralization in the Absence of Vital Effects Darren Scott Wilson Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Geological Sciences Patricia M. Dove, Chair J. Donald Rimstidt James. J. De Yoreo May 8, 2003 Blacksburg, Virginia Keywords: Biomineralization, Calcite, Strontium, Growth, Atomic Force Microscopy Copyright 2003, Darren Scott Wilson Nanoscale Effects of Strontium on Calcite Growth: A Baseline for Understanding Biomineralization in the Absence of Vital Effects Darren Scott Wilson (ABSTRACT) This study uses in situ atomic force microscopy (AFM) to directly observe the atomic scale effects of Sr on the monomolecular layer growth of abiotic calcite. These insights are coupled with quantitative measurements of the kinetics and thermodynamics of growth to determine the direction-specific effects of Sr on the positive and negative surface coordination environments that characterize calcite step edges. Low concentrations of strontium enhance calcite growth rate through changes in kinetics. A new conceptual model is introduced to explain this behavior. Higher concentrations of strontium inhibit and ultimately stop calcite growth by a step blocking mechanism. The critical supersaturation required to initiate growth (s*) increases with increasing levels of strontium. At higher supersaturations, strontium causes growth rates to increase to levels greater than those for the pure system. The step blocking model proposed by Cabrera and Vermilyea in 1958 does not predict the experimental data reported in this study because the dependence of s* upon strontium concentration is not the same for all supersaturations.
