In air, the oxide scale is composed of a duplex structure composed of spinel oxide, (Mn,Cr)3O4 in the external part and chromia, Cr2O3, in the inner part.
In Ar-1%H2-9%H2O, the oxide scale appears thinner than in air (0.9 vs 1.1 µm), but still composed of a duplex structure made of the spinel in the external part and chromia in the inner part (Fig.2 c and d).

Method of calculations All calculations were performed using the exact muffin-tin orbital method combined with the coherent potential approximation (CPA) for the electronic structure of random alloys [6].
However, the FM curve shows the double-minima structure, characteristic for Fe-based fcc alloys due to the presence of high-spin to low spin magnetic transition [12].

Since they are having one dimensional structure and semiconducting properties they are being studied as potential materials for FET based biosensor.
Summary The study demostrate a surface preparation with chitosan- -silicon for probe attachment to silicon nanowire, this study was done in order to undestand the binding chemistry between inoganic silicon nanowire and probe.

Mohandas et al. studied the effect of the chemistry of the steel and the welding process on the softening of the heat affected zone.
Kawata et al. studied the effect of ausforming on formation of upper bainite structure in Fe–9Ni–(0.15–0.5)C (mass%) alloys, focusing on the crystallographic feature of bainitic ferrite.
Furuhara et al. investigated the upper bainite structures in Fe–9Ni–(0.15–0.5)C (mass%) alloys transformed at temperatures between 723 and 623 K.

Existing researches on the absorbing properties of cement-based materials show that adding nano-materials can improve the performance of wave absorbing, 10-15mm thick samples made from cement mixed with nano-TiO2 powder were found very effective within 2-18GHz spectrum.[6-9] In this paper, the electromagnetic wave absorption performance of modified cement base material were studied, this research has important academic value in the development of large span structures’ camouflage technology, and improving stealth properties of concrete structures, etc.
