For many decades the accurate and precise determination of isotope ratios has remained a
very strong interest to many researchers due to its important applications in earth …

Nickel is an iron-peak element with 5 stable isotopes (see Table 1) which is both
cosmochemically abundant and rich in the information carried in its isotopic signature …

We report small but significant variations in the 58Ni/61Ni-normalised 60Ni/61Ni and
62Ni/61Ni ratios (expressed as ε60Ni and ε62Ni) of bulk iron and chondritic meteorites …

Although initial studies have demonstrated the applicability of N i isotopes for
cosmochemistry and as a potential biosignature, the N i isotope composition of terrestrial …

High-precision Ni isotopic variations are reported for the metal phase of equilibrated and
unequilibrated ordinary chondrites, carbonaceous chondrites, iron meteorites …

We report high-precision analyses of internally-normalised Ni isotope ratios in 12 bulk iron
meteorites. Our measurements of 60Ni/61Ni, 62Ni/61Ni and 64Ni/61Ni normalised to …

High-precision Ni isotope analyses of the differentiated andesitic meteorite Erg Chech 002
(EC 002), the oldest known crustal fragment of a planetesimal, show that short-lived 60Fe …

A sequential chemical separation technique for Cr, Fe, Ni, Zn, and Cu in terrestrial and
extraterrestrial silicate rocks was developed for precise and accurate determination of …

Among extinct radioactivities present in meteorites, 60 Fe (t_ {1/2}= 1.49 Myr) plays a key
role as a high-resolution chronometer, a heat source in planetesimals, and a fingerprint of …

We present a new technique for the accurate and precise determination of mass-dependent
variations in nickel isotope compositions in geological materials. Our method involves an ion …
