A new seaborgium isotope may unlock the path to discovering even shorter-lived superheavy nuclei through K-isomer states. An ...

Ecosystem responses to global change are often nonlinear. Ecological thresholds are tipping points beyond which small changes ...

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...

Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (∼40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and ...

These signatures preserve a record of how nitrogen was cycled in ancient oceans. By tracing changes in nitrogen isotope ratios, scientists can reconstruct how oxygen levels shifted over time. The team ...

Previously, inverse nitrogen isotope effects in atrazine degrdn. by Arthrobacter aurescens TC1 (i) delivered highly characteristic (13C/12C, 15N/14N) fractionation trends for pathway identification ...

THROUGH the investigations of A. O. Nier and co-workers1, it is known that the isotopic composition of carbon in living matter and related materials is different from that in carbonates.

Nitrogen dioxide, or NO 2, is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides, or NO x. Nitrogen dioxide forms when fossil fuels ...
