Another significant development for cobalt came with the creation of aluminum-nickel-cobalt (AlNiCo) magnets in the 1940s. AlNiCo magnets were the first replacement to electromagnets. In 1970, the industry was further transformed by the development of samarium-cobalt magnets, which provided previously ...
COBALTTRANSFERRINIRON-TRANSFERRINBINDING ACTIVITYBackground: Cobalt (Co) is an essential trace element. Available data suggest an interaction between cobalt and other ele- ments. In this study the characteristics of Co and iron (Fe) bindings to human apo-transferrin (apo-tf) have been investigated...
Central Pacific Cobalt-Rich Ferromanganese Crusts: Historical Perspective and Regional Variability Interelement correlations coupled with X-ray mineralogy, chemical analyses, and Q-mode factor analysis define five phases that compose ferromanganese crusts: 未 -MnO 2 , Fe-phases including Fe oxyhydroxide ...
Three genetic types of pyrite have been distinguished in the deposit; the framboidal, the anhedral-subhedral (with a large amount of pyritized bio-remains) , and the cobalt pyrite. The pre-iron ore framboidal pyrite of sedimentary origin recrystallized due to the reworking of ore-forming ...
There are slope break zones in the southwestern and northeastern parts of the study area, with a steep slope break in the southwest and a gentle slope break in the northeast (Fig. 3-b, d). Based on the quantitative calculation of the element cobalt, the ancient water depths of the slope...
This paper presents the fractal distribution of topography of seamounts from the West Pacific and the resource quantity of cobalt crust therein. The cobalt resource quantity has three to four variable fractal dimensions, corresponding to the distinct slopes and water depths of the seamount. The multip...
The semi-hard cobalt nano-ferrites are a subclass of ferrites. The coercive, stable, robust, crystalline, and resistive characteristics of mid-hard cobalt ferrites8. The octahedral position has more Co2+ ions, while the tetrahedral site contains more Fe3+ ions. The magnetic moment of Fe3+ ...
One can find the atomic mass of an atom in a couple of ways. One way is to refer to the periodic table of elements. Usually, the atomic mass of an atom can be seen under an element's symbol and atomic number; it is commonly only found in the form of the average atomic mass or ...
This study aimed to reveal the status and source apportionment of trace element soil pollution in a village with a relatively high incidence of lung cancer in China and determine the element migration characteristics from coal to road dust and soil. To this end, 24 soil samples, 48 road dust...
