Element 27 – Cobalt

Cobalt and Cobalt Compounds That Release Cobalt Ions In Vivo

This listing of the class of cobalt and cobalt compounds that release cobalt ions in vivo (as defined below) supersedes the previous listing of cobalt sulfate in the Report on Carcinogens. The compound cobalt sulfate was first listed in the Eleventh Report on Carcinogens in 2004 as reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity in experimental an...

Cobalt and Cobalt Compounds That Release Cobalt Ions In Vivo

The Report on Carcinogens includes two separate listings (i.e., profiles) for cobalt-related exposures: Cobalt and Cobalt Compounds That Release Cobalt Ions In Vivo and Cobalt-Tungsten Carbide: Powders and Hard Metals. Cobalt and cobalt compounds as a class are listed for the first time in the Fourteenth Report on Carcinogens, and this listing includes and supersedes the listing for cobalt sulf...

Finite element micromagnetism simulations on the magnetization reversal behaviors of cobalt nanotubes.

In this paper, we have used the finite element micromagnetism theory to simulate the magnetization (M) reversal behaviors of cobalt nanotubes with different lengths (L = 400, 600, 800 and 1000 nm). The inner radius and outer radius of nanotubes are 50 nm and 100 nm respectively. The simulation results show that all the nanotubes exhibit significantly anisotropic behaviors: the easy magnetizatio...

Material Flow Analysis for Identifying Rare Earth Element Recycling Potentials in the Eu-27

Rare earth elements (REEs) are essential for high-techology industrial sectors. This paper presents research on material flow analysis (MFA) applied to REEs in the EU-27. Innovative aspects of this research pertain to (i) considering potential lithospheric stocks of REEs in the EU and (ii) accounting for incomplete and imprecise information in MFA data reconciliation. Results obtained to-date p...
