Potential mapping measurements have been performed on passive surfaces in air using an Atomic Force Microscopy based technique, the Scanning Kelvin Probe Force Microscope (SKPFM). A linear relation was found between the potential measured this way and the corrosion potential in aqueous solution for a range of pure metals. The SKPFM can be considered to map the practical nobility of the surface....

The solidification microstructures formed in a model 6082 alloy with 0.2–1.0 wt % Fe were examined under different cooling rates and the effects of 0.5 Mn Al–5Ti–1B grain refiner addition investigated. results compared against Thermo-Calc, differential scanning calorimetry (DSC) curve analysis. promotes primary-Al refinement from growth restriction constitutional undercooling but increases detr...

In this work, the materials from different positions of 2219 aluminum alloy/304 stainless steel inertia friction welded tank with long‐term storage N 2 O 4 were studied. The results showed that corrosion product layer composed Fe 3 and FeCr was covered on surface steel. can effectively improve protection effect. Severe occurred in both sidewall bottom alloy, intergranular depths about 30 to 50μ...

The scalable chemical vapor deposition of monolayer hexagonal boron nitride (h-BN) single crystals, with lateral dimensions of ∼0.3 mm, and of continuous h-BN monolayer films with large domain sizes (>25 μm) is demonstrated via an admixture of Si to Fe catalyst films. A simple thin-film Fe/SiO2/Si catalyst system is used to show that controlled Si diffusion into the Fe catalyst allows exclusive...

In the title compound, [Fe(C(17)H(20)NO(2)Si)(2)], the Fe atom is situated on a crystallographic centre of inversion, leading to a perfectly staggered conformation of the Cp rings.

We present a detailed structural investigation via neutron diffraction of differently heat treated samples Fe 2 VAl and Fe 2+x V 1−x Al. Moreover, the magnetic behaviour of these materials is studied by means of µSR and Mössbauer-experiments. Our structural investigation indicates that quenched Fe 2 VAl, exhibiting the previously reported " Kondo insulating like " behaviour, is off-stoichiometr...

in this article, we have investigated the role of dimethylamine (dma), tributylamine (tba), triethanoleamine (tea), trishydroxymethylamine (trizma), and hexamethyleneterraamine (hmta), in the formation of zeolitic compounds. the experiments were carried out in acidic and basic media using si/al< 10 and si/a1>10. the structure of the resulting synthetic zeolites were similar to natro davyne, amm...

We present a comprehensive analysis of the damped Lyα abundance database presented in the first paper of this series. This database provides a homogeneous set of abundance measurements for many elements including Si, Cr, Ni, Zn, Fe, Al, S, Co, O, and Ar from 38 damped Lyα systems with zabs > 1.5. With little exception, these damped Lyα systems exhibit very similar relative abundances. There is ...
