Tungsten contains one isotope of mass 182 that is created when an isotope of
the element hafnium undergoes radioactive decay, meaning its elemental composition changes as it gives off radiation.
A Cologne working group involving Prof. Carsten Münker and Dr. Elis Hoffmann and their student Sebastian Viehmann (working with Prof. Michael Bau from the Jacobs University Bremen) have managed for the first time to determine the isotope composition of the rare trace
elements Hafnium and Neodymium in 2.7 - billion - year - old seawater by using high purity chemical sediments from Temagami Banded Iron Formation (Canada) as an archive.
Not exact matches
Nuclear reactors utilize control rods made from
elements such as cadmium, boron or
hafnium, all of which are efficient neutron absorbers.
The Temagami Banded Iron Formation, which was formed 2.7 billion years ago during the Neoarchean period, can be used as an archive because the isotopic composition of many chemical
elements such as
Hafnium and Neodymium directly mirrors the composition of Neoarchean seawater.
Scientists from MIPT have succeeded in growing ultra-thin (2.5 - nanometre) ferroelectric films based on
hafnium oxide that could potentially be used to develop non-volatile memory
elements called ferroelectric tunnel junctions.
