Mill Springs Mill, Kentucky : a history and analysis Open
The US Congress codified the National Historic Preservation Act (NHPA) of 1966, the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requi…
Location of Carbonate Ions in Metal-Doped Carbonated Hydroxylapatites Open
The environment model for the description of the location of carbonate ions in apatites predicts that approximately half of the carbonate occupies the apatite channel. This model relies on the influence of entities surrounding the carbonat…
Europium-Doped Carbonated Apatites Open
In this first exploration of europium-doped carbonated apatites the location of carbonate was determined using the environment model for the analysis of IR and NMR spectra. Europium-doped carbonated apatites, containing Eu/(Eu + Ca) mole r…

Worth a Closer Look: Raman Spectra of Lead-Pipe Scale Open
The identification and characterization of lead-bearing and associated minerals in scales on lead pipes are essential to understanding and predicting the mobilization of lead into drinking water. Despite its long-recognized usefulness in t…
The effect of incorporated carbonate and sodium on the IR spectra of A- and AB-type carbonated apatites Open
The substitution of carbonate in apatites has been voraciously explored for more than 60 yr. However, the characterization of the sites of carbonate substitution in apatite by the frequently used identification method, infrared spectroscop…
Substitution of sulfate in apatite Open
The substitution of sulfate in apatite is of potential importance in synthetic biomaterials used in bone repair and reconstruction. The counter ion (e.g., Na+, K+, Mg2+, Sr2+) in the sulfate reagent may also be used as a source of medicall…
