英文摘要
9508171 Banfield This research will explore fundamental relationships among crystal size, structural energy and surface characteristics of finely crystalline (nanocrystalline) minerals. Such nanocrystalline materials are common products of weathering and diagenetic reactions, and they account for a very large proportion of reactive sites in nature because of their inherently high surface areas. The objectives of this project are to explore the nature of crystallization and growth of nanocrystalline materials at low temperatures, to quantitatively investigate connections between measured surface energy and thermodynamic stability, and to model relationships among surface energy, surface structure and reaction rates.
