Sentence examples for a precursor phase from inspiring English sources

Octa-calcium phosphate (OCP) is believed to be a precursor phase to apatite, however octa-strontium phosphate does not exist.

Our results also are consistent with the reports of others that HAP precipitation occurs following the transformation of a precursor phase of amorphous calcium phosphate.

ACP has been previously reported in the otoliths of blue sharks and also shown to form as a precursor phase of carbonated hydroxyapatite in chiton teeth [18].

The nanoscale Zr-rich particles served as a precursor phase for the heterogeneous nucleation of the Zn-rich β-type strengthening precipitates during subsequent isothermal ageing at 180°C.

Although OCP has not been observed in vascular calcifications, it has been strongly suggested as a precursor phase to biological apatite found in natural and prosthetic heart valves (Tomazic et al. 1994; Nancollas and Wu 2000).

We further deduce that these Zr-rich particles served as a precursor phase for the heterogeneous nucleation of Zn-rich β1′ precipitates ([0001]α rods) and β2′ precipitates ((0001)α plates) in the Zr-rich core regions of the Mg alloy during subsequent ageing.

Apart from the presence of MgAg co-clusters, no evidence of a distinct precursor phase was observed.

By a combined use of μ-Raman and x-ray photoelectron spectroscopies, and scanning tunneling microscopy and spectroscopy, we were able to individuate a carbon precursor phase to graphene nucleation which coexists with small graphene domains.

However, it is a transient precursor phase to crystalline modification [1 4], so it is difficult to obtain in vitro.

Low-temperature ACPs (described by the chemical formula Ca x H y (PO4) z ·nH2O, n = 3 4.5; 15 20 % H2O) are often encountered as a transient precursor phase during precipitation of other CaPO4 in aqueous systems.

However, both types of precipitates develop out of an undefined precursor phase, in contrast to other Cu-alloyed PH13-8 Mo maraging steel grades.
