Iron is a chemical element; it has symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, ...
Iron(VI) also exists in theferrate ion FeO42-, and the elementalso forms complexes in which its oxidationnumber is zero (e.g. Fe(CO)5). View all 8.25 Definition Metallic element of atomic number 26, group VIII of the periodic table, aw 55.847, valences = 2,3; four stable isotopes...
To explain the strengthening mechanisms, we investigated the atomic distribution of the O and Fe in three alloys, Ti–0.14O–3.23Fe, Ti–0.34O–3.25Fe and Ti–6Al–4V–0.22O–0.20Fe. Combined with integrated differential phase contrast (iDPC), scanning transmission electron microscopy (STEM) ena...

The existence of two relaxation time constants signifies the development of a duplex passive layer on the porous Fe scaffold sample surface [[59], [60], [61], [62]]. In addition to this, it was observed that the value of ZIm and ZRe impedance was reduced as the random microporosity ...
Cell viability analysis, proliferation, differentiation using atomic force microscopy and gene expression analysis are commonly used in vitro toxicity testing techniques [153,154]. An initial assessment of biocompatibility is achieved by examining all of these parameters. This is important in determining ...

Introduction Iron oxide (mainly including hematite, magnetite, and wustite) is a kind of common compound that exists widely in nature [1]. It has become the focus of many studies because of its diverse ...
