Previous studies suggested an increase in the proportion of calcium phosphates (CaP) of the total phosphorus (P) pool in soils with a long-term poultry manure application history versus those with no or limited application histories. To understand and predict long-term P accumulation and release dynamics in these highly amended soils, it is important to understand what specific P species are be...

Dental enamel, a hierarchical material composed primarily of hydroxylapatite nanowires, is susceptible to degradation by plaque biofilm-derived acids. The solubility of enamel strongly depends on the presence of Mg(2+), F(-), and CO3(2-). However, determining the distribution of these minor ions is challenging. We show—using atom probe tomography, x-ray absorption spectroscopy, and correlative ...

background: this study was done to evaluate remineralizing potential of bioactive glasses (bags)and amorphous calcium phosphate‑casein phosphopeptide (acp‑cpp) on early enamel lesion.materials and methods: twenty freshly extracted mandibular premolars were sectioned sagittally.the buccal half was impregnated in acrylic resin blocks and treated with 37% phosphoric acid inliquid form, to deminera...
