Provision of optimum requirements for preparation of thin free targets from isotopes of chromium, scandium, zirconium, iron, copper [PDF]
Ядерна фізика та енергетика, 2008 Free films (targets) from high-melting chromium, scandium, zirconium, iron, copper isotopes of textured structures are prepared and explored by the method of thermal sputtering. About 2 sm2 films of ≤ 0,5 mg/sm2 thickness with homogeneity about 1 % and

A systematic look at chromium isotopes in modern shells – implications for paleo-environmental reconstructions [PDF]
Biogeosciences, 2018 The chromium isotope system (53Cr ∕ 52Cr, expressed as δ53Cr relative to NIST SRM 979) in marine biogenic and non-biogenic carbonates is currently being evaluated as a proxy for the redox state of the ocean.

Ab Initio Phase Diagram of Chromium to 2.5 TPa
Applied Sciences, 2022 Chromium possesses remarkable physical properties such as hardness and corrosion resistance. Chromium is also a very important geophysical material as it is assumed that lighter Cr isotopes were dissolved in the Earth’s molten core during the planet’s ...

Reactivity difference between protolytic forms of some macrocyclic chromium(III) complexes in ligand substitution and electron transfer processes [PDF]
, 2010 The review provides insight into the mechanism of ligand substitution and electron transfer (from chromium( III) to iron(III)) by comparison of the reactivity of some tetraazamacrocyclic chromium(III) complexes in the conjugate acid-base forms.
