The metal contents of ocean floor nodules, crusts and massive sulphides was estimated and an assessment of their commercial extractability were conducted. The metals considered were iron, manganese, copper, nickel, cobalt, molybdenum, platinum, gold and si ...

Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be ...
The objective was to explore how ferritin-H deletion influences Fe-59-distribution and excretion-kinetics in mice. Kinetics of Fe-59-release from organs, whole-body excretion, and distribution-kinetics of intravenously injected Fe-59 trace amounts were com ...
We examine the effect on atmospheric CO2 of the occurrence of increased shallow water carbonate deposition and regrowth of the terrestrial biosphere following the last glacial. We find that contrary to recent speculations that changes in terrestrial carbon ...
The renewable-electricity-powered CO2 electroreduction reaction provides a promising means to store intermittent renewable energy in the form of valuable chemicals and dispatchable fuels. Renewable methane produced using CO2 electroreduction attracts inter ...
Periodic arrays of elongated cobalt islands exchange coupled to continuous Permalloy thin films were fabricated using silicon nitride stencil masks and the magnetic spin configurations during magnetization reversal were studied with photoemission electron ...
A microstructural analysis and tensile tests were performed on two oxide dispersion strengthened ferritic/martensitic steels. Dispersion hardening represents an interesting approach to improve the mechanical properties at elevated temperatures, as they are ...
It was suggested that multilayered accretionary rims composed of ferrous olivine, andradite, wollastonite, salite-hedenbergitic pyroxenes, nepheline, and Ni-rich sulfides around Allende calcium aluminum-rich inclusions (CAIs) are aggregates of gas-solid co ...
Three diamond workers had occupational asthma attributed to the inhalation of cobalt powder. The exposure originated from high speed polishing disks with an abrasive consisting of microdiamonds cemented in extra fine cobalt not alloyed to tungsten carbide. ...
The modulation of the electronic structure of cobalt islands on Cu(111) by the Moire pattern of an Ag overlayer is investigated. Acquisition of tunneling spectroscopy maps reveals a local modification of both the energy and the amplitude of the cobalt-rela ...
