A 1500-year record of mercury isotopes in seal feces documents sea ice changes in the Antarctic
Communications Earth & Environment, 2023 Temporal and spatial variations in sea ice coverage at high Northern Hemisphere latitudes have been shown to affect the photodegradation of methylmercury in seawater and the mercury isotope signatures in biological samples, suggesting the potential of ...

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Geochemistry, Geophysics, Geosystems, 2023 Anomalous mercury (Hg) contents recorded near the Permian‐Triassic boundary (PTB) are often linked to Siberian Traps Large Igneous Province (STLIP) volcanism and the Permian‐Triassic boundary mass extinction (PTBME).

Investigation of 0+ states in mercury isotopes after two-neutron transfer
EPJ Web of Conferences, 2014 Using the high-resolution Q3D magnetic spectrograph at the Maier-Leibnitz Laboratory (MLL) Tandem accelerator in Munich, we studied 0+ excitations in the mercury isotopes 198Hg, 200Hg, and 202Hg after two-neutron transfer. We only observed 4-6 excited 0+

Compositions of mercury isotopes for lighting
, 2015 Described herein is a mercury sample that has an isotopic composition that differs from the naturally occurring distribution of isotopes. In various configurations of an isotopically tailored mercury sample, the fraction of one or more isotopes is increased or decreased with respect to the natural fraction(s).

Mercury Elemental and Isotopic Abundances in Mercury‐Manganese Stars
The Astrophysical Journal, 1999 Hg II abundances have been determined for 42 mercury-manganese (HgMn) stars by fitting synthetic spectra to observed spectra of the 3984 A Hg II line. Twenty of the stars had lines sharp enough to allow their Hg isotopic abundance mixes to be estimated. The Hg abundance is reported for more HgMn stars here than in any other single work.

Charge radii, moments, and masses of mercury isotopes across the N=126 shell closure [PDF]
, 2021 Combining laser spectroscopy in a Versatile Arc Discharge and Laser Ion Source (VADLIS) with Penning-trap mass spectrometry at the CERN-ISOLDE facility, this work reports on mean-square charge radii of neutron-rich mercury isotopes across the N=126 shell

The Separation of the Isotopes of Mercury [PDF]
Nature, 1920 WE have been successful in achieving a partial separation of the isotopes of mercury by evaporating, mercury at low pressure and condensing the evaporated atoms on a cooled surface. The rate of evaporation of the isotopes being inversely proportional to the square root of their atomic weight, and practically every atom leaving the liquid being ...

Nature, 1925 THANKS to generous financial assistance, for which I am indebted to the Department of Scientific and Industrial Research, I have been enabled to build a mass-spectrograph giving double the dispersion of the one previously in use. The final adjustments of this instrument are by no means complete, but it has already given results of great promise.
