Herle, P. S., Ellis, B., Coombs, N. & Nazar, L. F. Nano-network electronic conduction in iron and nickel olivine phosphates.
In situ soft X-ray absorption provides important information on the valence and electronic structure of iron during treatments, with a time scale down to 30 s.
These results help demonstrate the predominant role played by H-Bonding and subtle changes in its orientation in determining the geometric and electronic structure of iron porphyrin based active sites in nature.
Electronic properties of iron prepassive and passive films as well as ionic and electronic transfer reactions at the film|solution interface were discussed on the basis of a band structure model of the surface oxide film and the potential distribution at the interface.
Besides carbonaceous additives, another approach to improve the electronic conductivity of iron trifluoride is doping with other transition metals.
The pattern obtained for bare maghemite nanoparticle was due to the intrinsic property of the electronic transition in iron oxides such as the ligand to metal charge transfer transition.
Nuclear forward scattering (NFS) data were collected at the same time as the NIS data to monitor the electronic state of iron, and X-ray diffraction was used to confirm the identity of bridgmanite off-line after laser heating.
The influence of the oxygen vacancy in the magnetic and electronic properties of iron and cobalt as impurities in a DMO configuration in rutile SnO2 was studied using first principle calculations performed within the spin-density functional theory.
There is also an increase in some sectors, the highest being in leather products at 0.76%, vegetable, fruits and nuts at 0.12%, oil and gas, paper products, electronic equipment and iron, steel and non-metallic mineral products.
Electronic transitions in iron present a challenge, however, and the apparent inconsistency between experimental and computational results on the stability of the intermediate spin state of Fe2+ in bridgmanite remains controversial (e.g., Stackhouse 2008; McCammon et al. 2013; Shukla et al. 2015).
