Application of Nitrogen and Oxygen Isotopes for Source and Fate Identification of Nitrate Pollution in Surface Water: A Review

open access: yesApplied Sciences, 2018
Nitrate pollution in surface water has become an environmental problem of global concern. The effective way for controlling the nitrate pollution of surface water is to identify the pollution source and reduce the input of nitrate.

Chiral three-nucleon forces and bound excited states in neutron-rich oxygen isotopes [PDF]

open access: yes, 2013
We study the spectra of neutron-rich oxygen isotopes based on chiral two- and three-nucleon interactions. First, we benchmark our many-body approach by comparing ground-state energies to coupled-cluster results for the same two-nucleon interaction, with ...

Chiral three-nucleon forces and the evolution of correlations along the oxygen isotopic chain [PDF]

open access: yes, 2015
The impact of three-nucleon forces (3NFs) along the oxygen chain is investigated for the spectral distribution for attachment and removal of a nucleon, spectroscopic factors and matter radii. We employ self-consistent Green's function (SCGF) theory which

Oxygen Isotope Geochemistry of Oceanic Arc Lavas [PDF]

open access: yesMineralogical Magazine, 1998
Variations of oxygen isotope ratios in arc-related lavas can constrain the contributions of subducted crustal igneous rocks, sediments, and fluids to the sub-arc mantle. We have measured oxygen isotope ratios in 72 arc and back-arc lavas from five ocean–ocean subduction zone systems using laser-fluorination analyses of olivine and other phenocrysts and

Advances and Challenges in Palaeoenvironmental Studies Based on Oxygen Isotope Composition of Skeletal Carbonates and Phosphates

open access: yesGeosciences, 2021
Oxygen isotopes are widely used in palaeoenvironmental and palaeoclimatic studies as they record variations in the precipitation temperature of biogenic carbonates and phosphates.

Progress of Analytical Techniques and Application of Triple Oxygen Isotopes in Dissolved Oxygen

open access: yesJournal of Isotopes
Oxygen is one of the essential elements in Earth's ecosystem,with stable isotopes including δ16O,δ17O,and δ18O. The composition of oxygen stable isotopes (δ17O,δ18O) exhibits different fractionation patterns in various biogeochemical reactions,making ...
