Copepod nauplii use phosphorus from bacteria, creating a short circuit in the microbial loop.

Ecology Letters, 2019
In subtropical oceans phytoplankton carbon: phosphorus (C : P) ratios are high, and these ratios are predicted to increase further with rising ocean temperatures and stratification.

Coastal sediments record decades of cultural eutrophication in Tampa Bay, Florida, USA

Ecological Indicators
Phosphorus (P) sustainability is a complex problem – it is a limited resource critical for agricultural productivity, but fertilizer production generates extensive phosphogypsum waste and can impair downstream water quality.

A Dual Isotope Protocol to Separate the Contributions to Phosphorus Content of Maize Shoots and Soil Phosphorus Fractions from Biosolids, Fertilizer and Soil

Current Agriculture Research Journal, 2018
Separation of the phosphorus (P) contributions from soil, fertilizer and biosolids to plants has not been possible without the aid of radioisotopes. Dual labelling of soil with 32P and fertilizer with 33P isotopes has been used to partition the sources ...

Effects of benthic algae on release of soluble reactive phosphorus from sediments: a radioisotope tracing study

Water Science and Engineering, 2015
AbstractTo evaluate the effect of benthic algae on soluble reactive phosphorus (SRP) release from sediments in shallow lakes, experiments on SRP release with and without benthic algae in sediment cores and an experiment on SRP uptake by benthic algae were conducted using the radioisotope (32P) tracing method.

New approaches to investigating the function of mycelial networks [PDF]

, 2005
Fungi play a key role in ecosystem nutrient cycles by scavenging, concentrating, translocating and redistributing nitrogen. To quantify and predict fungal nitrogen redistribution, and assess the importance of the integrity of fungal networks in soil for ...

Phosphorus-32, a Clinically Available Drug, Inhibits Cancer Growth by Inducing DNA Double-Strand Breakage

PLoS ONE, 2015
Radioisotopes that emit electrons (beta particles), such as radioiodine, can effectively kill target cells, including cancer cells. Aqueous 32P[PO4] is a pure beta-emitter that has been used for several decades to treat non-malignant human ...

Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

Angewandte Chemie, Volume 138, Issue 8, 16 February 2026.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Discovery of the Isotopes with 11 <= Z <= 19

, 2011
A total of 194 isotopes with 11 $\le$ Z $\le$ 19 have been identified to date. The discovery of these isotopes which includes the observation of unbound nuclei, is discussed.
