However, we do not yet understand the detailed physical mechanism of how the increase in ion mass is linked to performance improvement. (sciencedaily.com)
If influences brought about by differences in ion mass can be clarified theoretically, we can accurately predict confinement improvements that are observed in experiments. (sciencedaily.com)
When the team bombarded the fossils with charged particles and then analyzed the particles that were knocked from the surface (a technique called time - of - flight secondary ion mass spectrometry), they chemically identified the remnants of eumelanin, a pigment that typically lends a black or brown color to skin or feathers.
