Dr. Benjamin Rotstein and collaborators unveil an operationally simple method to prepare carbon isotope-labeled versions of drugs and diagnostics. The development of new pharmaceuticals relies on the ...

Scientists have produced one of the most neutron-rich isotopes, hydrogen-6, in an electron scattering experiment. The experiment presents a new method for investigating light, neutron-rich nuclei and ...

Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from oxidative stress, regulating thyroid hormones, strengthening the immune system, ...

Mg isotope compositions of some typical geological standard samples measured by the DS method and the SSB method in different laboratories. The sample-standard-bracketing (SSB) method and double-spike ...

Image of an isotope pattern screening technique for the selective detection of selenium (Se)-containing compounds using liquid chromatography (LC)-electrospray ionization mass spectrometry. Although ...
