Researchers may have just spotted the elusive, ephemeral nucleus of nitrogen-9 ... hunting for an isotope of oxygen, oxygen-11, by smashing high-powered beams of oxygen-13 nuclei into beryllium ...

New research from the Monell Chemical Senses Center and Temple University about nutritional biomarkers using carbon and ...

With five more protons than should be stable, the newly discovered nitrogen-9 isotope ... smashed oxygen-13 atoms into beryllium in a bid to create another isotope called oxygen-11.

To measure the impact of integrated crop-livestock practices and green manuring, scientists use stable isotopes which do not emit radiation, such as nitrogen-15 and carbon-13, on small experimental ...
