The petrology and genesis of the Paleoproterozoic mafic intrusion-hosted Co-Cu-Ni deposit at Hietakero, NW Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2018
Cobalt is a highly sought-after metal due to its economic importance in many hightech applications. It is mainly obtained from sedimentary-hosted Cu-Co deposits and magmatic Ni-Cu deposits as a by-product. We describe a recently discovered Co-enriched Cu-

Development of a Small-Sized, Flexible, and Insertable Fiber-Optic Radiation Sensor for Gamma-Ray Spectroscopy

open access: yesSensors, 2015
We fabricated a small-sized, flexible, and insertable fiber-optic radiation sensor (FORS) that is composed of a sensing probe, a plastic optical fiber (POF), a photomultiplier tube (PMT)-amplifier system, and a multichannel analyzer (MCA) to obtain the ...

A benthic bioindicator reveals distinct land and ocean-Based influences in an urbanized coastal embayment. [PDF]

open access: yesPLoS ONE, 2018
Biogeochemical maps of coastal regions can be used to identify important influences and inputs that define nearshore environments and biota. Biogeochemical tracers can also track animal movement and their diet, monitor human coastal development, and ...

Fundamental understanding of re-dispersion of cobalt on supported model Fischer-Tropsch catalysts [PDF]

open access: yes, 2011
The aim of this study was to investigate how the catalytically active material may redisperse during consecutive oxidation-reduction steps (OROR) for a model supported-cobalt catalyst to give insight into the regeneration process of a spent supported ...

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean

open access: yesHeliyon, 2018
Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated ...

Quantitative Cherenkov-excited fluorescence emission dosimetry for HDR Co-60 brachytherapy: Calibration and planar validation against TPS. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Background Accurate dose verification in High‐Dose‐Rate (HDR) brachytherapy presents a significant challenge due to steep dose gradients and the absence of beam collimation. Conventional quality assurance (QA) methods typically rely on point detectors or film‐based techniques, which lack the capability to provide real‐time, full‐field ...

Allosteric inhibition of cobalt binding to albumin by fatty acids : implications for the detection of myocardial ischemia [PDF]

open access: yes, 2012
The biomarker "ischemia-modified albumin" (IMA), measured by the albumin-cobalt-binding assay (ACB assay), is the only FDA-approved biomarker for early diagnosis of myocardial ischemia.

Cobalt and inorganic cobalt compounds

open access: yes, 2006
Cobalt is a naturally occurring element with a number of radioactive isotopes. It is a silvery grey solid at room temperatures. Sources of exposure are both natural and anthropogenic with the largest source of exposure to the general population is ...
