The corrosion tests were conducted in brine solution saturated with H2S and two type of iron compounds (FeS and FeSO4).
The present work aims to investigate the effect of ferrous ion on the corrosion behavior of 410SS and further understand the corrosion mechanism of martensite stainless steel in H2S environment, through weight loss test, scanning electron microscopy (SEM) and X-ray diffraction (XRD).

Common commercial fertilizers contain “mobile” nitrogens that can be easily transformed into other nitrogen compounds.
This is because nitrogen can be easily transformed into other nitrogen compounds that can not be absorbed by plants in the form of available nutrients such as ammonium ion (NH4+) dan nitrate ion (NO3-).
The polyurethane multilayer method aimed to withhold nitrogen as nutrition longer than uncoated granular fertilizer.
Then, devarda alloy was added into 10 ml of sample to perform distillation in Nitrogen Analyzer GERHARDT type Vapodesk.
This is also in line with statements on a research journal about nitrogen release behaviors on field tests [18].

Therefore, the current study aims to investigate the effect of roll speed ratio on strip shape and profile of cold rolled steel strip.

Carbonaceous compounds, such as activated carbon, single-walled carbon nanotubes (SWCNT), double walled carbon nanotubes (DWCNT), and multi-walled carbon nanotubes (MWCNT) have attracted a considerable attention as raw materials for nano-scale, nanocomposite in particular, enhancement [5-7].
Continuously, PPy/f-MWCNT is considered as an excellent NCs compounds in which cost-effectiveness, high mechanical strength and chemical stability as well as relatively high electrical conductivity can be obtained; the latter is mainly attributed to the considerable surface area and good adhesion to substrate [9].
This was accompanied with energy dispersive x-ray (EDS) to examine the elemental compositions of the used compounds. 3.

Introduction AlN belongs to compounds of the III-V family with a bandgap of 6.2 eV and hexagonal close-packed wurtzite crystal structure [1].
The aim of this study is to synthesize Cr doped AlN thin film by DC sputtering and RF sputtering co-deposition method at the glass and silicon substrates, where two types of silicon substrate conditions were studied, the as-deposited and annealed silicon substrate based AlN: Cr thin films and their structural analysis was performed by XRD.
This kind of luminescence is usually observed in semiconductor compounds such as IIIb-Vb and IIb-VIb compounds and chromium belongs to VIb [19].

In addition, the determination of the real structure of the compound is possible only by indirect experimental methods.
It is aimed at determining whether the synthesis of Cu-Au nanoalloy with various percentages of gold atoms can lead to a different size distribution.
