Iron (Fe, atomic number 26) is a redox-active transition metal element found in living systems as Fe2+ or Fe3+ ions. It is rarely found free in biology, but is bound to proteins such as ferritin or haem, to form metalloproteins such as haemoglobin, which is responsible for the transpor...
The ν- and Z-dependence of the transient magnetic field in iron have been investigated for light ions. From existing data and the present work on transient fields for 20Ne and 24Mg at initial velocities up to v i v 0 = 8 (v 0 = c 137) a marked atomic shell structure has been ...
Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous nanofoam structure. We find that during the elastic phase of compres...
2.7 Chemical Properties Iron is the fourth most abundant element in the earth’s crust (5%). It is a transition metal and is placed within the d-block of the periodic table and naturally occurs coordinated with other elements. It is mainly extracted from hematite (Fe2O3) and limonite (Fe...

Electronic properties of Fe-alloys In order to explore any distinctive electronic features of our proposed Earth core Fe-alloys, Bader charge analyses were conducted to evaluate the charge transfer between Fe atoms and impurity atoms in the systems, as shown in Fig. 346. For most impurities with...
and ductile α–β titanium–oxygen–iron alloys. Here we integrate alloy design with additive manufacturing (AM) process design to demonstrate a series of titanium–oxygen–iron compositions that exhibit outstanding tensile properties. We explain the atomic-scale origins of these properties using ...
