Phosphorus, Sulfur, and Silicon and the Related Elements, 2000
Abstract The reduction of phosphorus acid chlorides as well as hypophosphates, pyrophosphates and mixed P(III)-P(V) anhydrides with alkali metals (Li, Na, K)in NH3 liq./THF solution and potassium naphthalenide was investigated. It was found that this type of phosphorus compounds easily undergo reduction: a) >P(O)Cl to >P(O)H; b) >P(O)P(O) P(O)H; c) >P ...

A summary of new findings regarding alterations of magnesium (Mg2+) and phosphorus (P) metabolism are reviewed for the clinician caring for patients in general wards. Alterations in serum concentrations of Mg2+ and P are frequently observed in acute or very ill patients in emergency rooms or intensive-care areas.

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970
Abstract An investigation was made into the nature and extent of phosphorus and of nonhistone phosphorylated molecular species in histones and histone fractions. The distributions of radiophosphorus, of labeled nucleic acid precursors and of intact labeled nucleic acids during histone preparation and fractionation were presented.

Wetland phosphorus dynamics and phosphorus removal potential
Water Environment Research, 2022AbstractWetlands are typically defined as inundated areas with hydric soils forming a transitional zone between terrestrial and aquatic systems. Wetlands have numerous ecosystem benefits, one of which is the potential to mitigate or reverse eutrophication of surface water bodies.

Science, 1968
Phosphorus, the element itself, becomes superconducting near 4.7°K and at pressures exceeding 100 kilobars. This constitutes one of the four last missing links in the proof that superconductivity is normal behavior for every truly metallic sp element. The three remaining ones are arsenic, sulfur, and iodine.
