TL;DR: In this paper, the authors presented a comprehensive finite element model for the numerical simulation of Hydrogen Induced Cracking (HIC) in steel pipelines exposed to sulphurous compounds, such as hydrogen sulphide (H2S), in order to mimic the pressure build-up mechanism related to the recombination of atomic hydrogen into hydrogen gas within the crack cavity.

TL;DR: In this paper, the concept of dipolar relaxation was introduced to interpret electrochemical impedance spectroscopy (EIS) data for polymer coated metal electrodes, and it was shown that the water uptake of a paint film could be evaluated from the Cole-Cole capacitance at infinite frequency C(), because the plasticizing effect induced by absorbed water in lower frequencies may lead to an overestimation of water uptake.

TL;DR: In this article, a process for sequestrating carbon emitted into the atmosphere in the form of CO2 comprises: a) concentrating CO2 in the liquid phase; b) electro-reduction in an aprotic medium to a compound in which the carbon changes to oxidation number +3 in the forms of oxalic acid or formic acid; c) if appropriate, a step for re-extracting Oxalic or Formic acid in the aqueous phase; and d) a step of mineralization by reaction with a compound of an element M, resulting

TL;DR: In this paper, the effects of stoichiometric composition, average weight between cross-links, and temperature changes as interpreted by glass transition effect were investigated in hydrogen sulphide containing sour media.

TL;DR: In situ Raman analysis was applied to identify the corrosion products formed on iron coated with epoxy-amine varnish and exposed to sodium chloride solution saturated by hydrogen sulfide or carbon dioxide as discussed by the authors.
