With increasing impact of hydrogen-based economy it is necessary to consider relevant hydrogen embrittlement effects and risks resulting from it. As higher gas pressures are in discussion, the use of higher steel strength levels as compared to existi

The impact was examined of surface ordering of 50 nm-thick copper phthalocyanine (CuPc) layers on the layer's susceptibility to ambience-induced degradation processes. The surface morphology of CuPc layers obtained by physical vapor deposition with d

A sample iron molybdenum alloy with 3.4 wt% (2 at%) molybdenum, and pure iron, are exposed to hydrogen sulfide saturated saline solution for up to 56 days. In addition, their behavior under anodic polarization in the same electrolyte is investigated.

The corrosion of metals, mainly steels, in contact with H 2 S-containing solutions is a general problem especially in gas and oil production. The corrosion products are hydrogen and iron sulfides. Penetration of the hydrogen into the material leads t

Gas adsorption in metal–organic-frameworks (MOFs) can dramatically affect the size of the crystals (expansion and/or shrinkage) or lead to distortion of their porous structure/framework. This can strongly affect mechanical properties of MOFs potent

Polymer coatings are widely used to protect metals from corrosion. Coating adhesion to the base material is critical for good protection, but coatings may fail because of cathodic delamination. Most of the experimental studies on cathodic delaminatio
