Surface Characterization of Calcium Phosphates

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Wendy Shaw
Project type
Large-Scale EMSL Research
Heterogeneous nucleation is important in the development of biominerals such as bone, teeth and mollusk shells, but often, initial nucleation events are not understood at a mechanistic level(1). It…

Enamel biomineralization: Solution- and solid-state NMR

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Garry Buchko
Project type
Exploratory Research
Dental enamel, the layer of elongated carbonated hydroxyapatite on the outer layer of the tooth, is the hardest tissue in the human body. It needs to be strong because it cannot repair itself nor can…
