2014-3-15 · Since Fe 3 P is isostructural with Fe 3 S, its high-pressure behavior will provide valuable insights into the structural evolution of Fe 3 S and implications for phosphorus storage in planetary cores. Therefore we carried out ab initio calculations to explore the stabilities of Fe 3 P in several structures.

2021-1-18 · High Blood Phosphate and Poverty. Two studies have linked high blood phosphate with poverty. In the first study of 14,000 US adults, participants with income below the poverty level were twice as likely to have high blood phosphate levels (≥ 4.4 mg/dL) []. Similarly, in the second study with over 2,800 people, those who had the lowest income or were unemployed
