The corrosive breakdown of thin iron films supported on silicon substrates under a number of conditions is presented-in particular to understand better how iron, and hence ferritic steel, behaves in a salty water environment. A combination of X-ray and neutron reflectometry was used to monitor the structures of both metal and oxide surface layers and also organic corrosion inhibitors adsorbed at the iron/aqueous interface. A range of behavior in seawater was observed, including complete dissolution and void formation under the metal surface. Importantly, two simple treatments-UV/ozone or soaking in ultrapure water-were found to significantly protect the iron surface for considerable lengths of time, although evidence of pitting corrosion began after around 10 days. The underlying causes of the efficacies of these treatments were further investigated using X-ray photoelectron spectroscopy. In addition, three potential corrosion inhibitors were investigated: (i) dodecyltrimethylammonium bromide (DTAB) demonstrated no ability to protect the surface; (ii) sodium dodecyl sulfate (SDS) appeared to accelerate corrosion; and (iii) bis(2-ethylhexyl)phosphate showed an impressive level of protection (the neutron reflectometry results indicated a thick diffuse layer of surfactant of 23% surface coverage). These findings have been interpreted in terms of preferential inhibitor adsorption at cathodic and anodic surface sites (depending on the nature of the inhibitor).

“…The Multi-Blade [1][2][3][4][5] is a 10 B-based detector for neutron reflectometry instruments [6][7][8]. The detector requirements are set by the two reflectometers that are being designed for the European Spallation Source (ESS [9]) in Sweden: FREIA [10,11] (horizontal reflectometer) and ESTIA [12][13][14] (vertical reflectometer).…”

Neutron reflectometry with the Multi-Blade ¹⁰ B-based detector

et al. 2018

View full text Add to dashboard Cite

The Multi-Blade is a boron-10-based gaseous detector developed for neutron reflectometry instruments at the European Spallation Source in Sweden. The main challenges for neutron reflectometry detectors are the instantaneous counting rate and spatial resolution. The Multi-Blade has been tested on the CRISP reflectometer at the ISIS Neutron and Muon Source in the UK. A campaign of scientific measurements has been performed to study the Multi-Blade response in real instrumental conditions. The results of these tests are discussed in this paper.

“…Their design, therefore, does not always include a polarizer as a standard component. However, Polarized Neutron Reflectometry PNR is a constantly growing area in neutron scattering [4][5][6][7][8][9][10][11][12] and the need to at least temporarily implement a polarization option is desirable if only a particular unpolarized reflectometer allows for the installation of a certain sample environment. In this case, the temporary character of the polarization solution, a fast and zero-alignment installation and an experimental simplicity are the most decisive factors.…”
