Immersion experiment was carried out to investigate the CO 2 corrosion behavior of low-alloy steel used for pipeline at vapor-saturated CO 2 and CO 2 -saturated brine conditions by revealing microstructure, corrosion rate, corrosion phases, surface/cross-section morphology, and elements distribution. The results demonstrate that mass losses at both conditions are approximately linear to corrosion time with log scale, and the corrosion rate at vaporsaturated CO 2 condition is greatly lower than that at CO 2 -saturated brine condition. The main corrosion phases consisting of inner layer and outer layer are Cr-rich compounds and FeCO 3 crystals, respectively. Corrosion products on the coupon surface produced at vapor-saturated CO 2 condition are formed locally, while the ones produced at CO 2 -saturated brine condition deposit on the coupons surface homogeneously. That distinction is caused by the difference of formation process of corrosive solution. According to the experimental results, corrosion mechanisms of low-alloy steel at both conditions are discussed to illustrate CO 2 corrosion behavior.

Use of SnOx:F in the Recycling of Silicon Solar Cells

Amongst the many parts of a silicon cells photovoltaic module, silicon is the most important and expensive constituent. Thus, research on silicon recycling from damaged cells can lead to economic and environmental benefits. In this work, the broken silicon cells were tailored to function along with the fluorine-doped tin oxide as the transparent electric conductors. The broken silicon cells were analyzed by the current density versus voltage plots, together with the Mott-Schottky, X-rays diffraction and fluorescence analysis. Under light, the damaged cells sandwiched between the two transparent electric conductors presented photovoltaic effect. However, such effect was not obtained after the removal of the antireflection layer due to the destruction of the n-type layer as demonstrated by the Mott-Schottky analysis. The X-rays diffraction revealed samples rich on silicon atoms and the presence of aluminum atoms as impurity.

FeCO₃ Synthesis Pathways: The Influence of Temperature, Duration, and Pressure

FeCO3 is present as scales in process equipment, corrosion products, geological systems, and carbon storage. It is therefore crucial to investigate the properties of FeCO3 to understand scaling in all these systems. However, FeCO3 is not commercially available, and when used in the lab it is either obtained through extraction of geological formations or synthesized in-house. Geologically formed FeCO3 contains multiple impurities, which will affect its overall properties, and the synthesized product is highly sensitive to either oxidation or the synthesis pathways. This work explores the parameter space of a synthesis route routinely and pathways for FeCO3. We characterized the structure of FeCO3 using X-ray powder diffraction and its thermal properties with thermogravimetric analysis and scanning electron microscopy. We show how synthesis parameters influence either the macroscopic or microscopic properties of the synthesized product. Our study serves as a guideline for future research regarding what parameters to choose when synthesizing FeCO3 and what product can be obtained. We herein present a novel fundamental understanding of FeCO3.
