Reconciling disparate views of template-directed nucleation through measurement of calcite nucleation kinetics and binding energies
Autor: Patricia M. Dove, James J. De Yoreo, Laura M. Hamm, Debin Wang, N. Han, Jinhui Tao, Anthony J. Giuffre
Publikováno v: Proceedings of the National Academy of Sciences. 111:1304-1309
The physical basis for how macromolecules regulate the onset of mineral formation in calcifying tissues is not well established. A popular conceptual model assumes the organic matrix provides a stereochemical match during cooperative organization of

Raman spectroscopic characterization of the magnesium content in amorphous calcium carbonates
Autor: Patricia M. Dove, Laura M. Hamm, Dongbo Wang, Robert J. Bodnar
Publikováno v: Journal of Raman Spectroscopy. 43:543-548
A series of Mg-bearing synthetic amorphous calcium carbonates (ACC) were characterized by Raman spectroscopy. The spectra showed a systematic increase in the carbonate n1 peak position from the control samples that contained 0.0mol % MgCO3 to samples

Molecular Dynamics of Ion Hydration in the Presence of Small Carboxylated Molecules and Implications for Calcification
Autor: Patricia M. Dove, Laura M. Hamm, Adam F. Wallace
Publikováno v: The Journal of Physical Chemistry B. 114:10488-10495
The aspartate-rich macromolecules found at nucleation sites of calcifying organisms are widely implicated in regulating biomineral formation. Anecdotal evidence suggests that their ability to influence the onset of nucleation and composition of calci

Polysaccharide chemistry regulates kinetics of calcite nucleation through competition of interfacial energies
Autor: James J. De Yoreo, Anthony J. Giuffre, Patricia M. Dove, Laura M. Hamm, N. Han
Publikováno v: Proceedings of the National Academy of Sciences of the United States of America. 110(23)
Calcified skeletons are produced within complex assemblages of proteins and polysaccharides whose roles in mineralization are not well understood. Here we quantify the kinetics of calcite nucleation onto a suite of high-purity polysaccharide (PS) sub

Atomistic simulations—molecular dynamics (MD) and Monte Carlo (MC) simulations, ab initio and density functional theory (DFT) calculations—have proved useful in gaining insight into the molecular basis of fundamental processes in aquatic geochemi

Revisiting geochemical controls on patterns of carbonate deposition through the lens of multiple pathways to mineralization
Autor: J. J. De Yoreo, Anthony J. Giuffre, Laura M. Hamm, Dongbo Wang, J. Donald Rimstidt, Takuya Echigo, John P. Grotzinger, Patricia M. Dove
The carbonate sedimentary record contains diverse compositions and textures that reflect the evolution of oceans and atmospheres through geological time. Efforts to reconstruct paleoenvironmental conditions from these deposits continue to be hindered

Molecular Dynamics of Cation Hydration in the Presence of Carboxylated Molecules: Implications for Calcification
Autor: Adam F. Wallace, Laura M. Hamm, Patricia M. Dove
Publikováno v: MRS Proceedings. 1301
Biomolecules rich in aspartic acid (Asp) are known to play a role in biomineral morphology and polymorph selection, and have been shown to greatly enhance the growth kinetics of calcite. The mechanism by which these compounds favor calcification may

The thermodynamics of calcite nucleation at organic interfaces: Classical vs. non-classical pathways
Autor: Patricia M. Dove, Thomas Yong-Jin Han, Udo Becker, John H. Harding, Qiaona Hu, Michael H. Nielsen, Colin L. Freeman, Jonathan R. I. Lee, Jinhui Tao, Laura M. Hamm, J. J. De Yoreo
Publikováno v: Faraday Discussions. 159:509
Nucleation in the natural world often occurs in the presence of organic interfaces. In mineralized tissues, a range of macromolecular matrices are found in contact with inorganic phases and are believed to direct mineral formation. In geochemical set
