“…However, it was verified in a recent study by our research group that electrodeposition with cathodic limit potentials of −0.30 V (vs. SCE) is also viable [67]. Indeed, some studies have shown graphene oxide electrodeposition in the anodic regime due to the electrostatic attraction between the positively charged electrode surface and negatively charged graphene oxide sheets [68,69].…”

The use of graphene and its derivatives in the development of electrochemical sensors has been growing in recent decades. Part of this success is due to the excellent characteristics of such materials, such as good electrical and mechanical properties and a large specific surface area. The formation of composites and nanocomposites with these two materials leads to better sensing performance compared to pure graphene and conductive polymers. The increased large specific surface area of the nanocomposites and the synergistic effect between graphene and conducting polymers is responsible for this interesting result. The most widely used methodologies for the synthesis of these materials are still based on chemical routes. However, electrochemical routes have emerged and are gaining space, affording advantages such as low cost and the promising possibility of modulation of the structural characteristics of composites. As a result, application in sensor devices can lead to increased sensitivity and decreased analysis cost. Thus, this review presents the main aspects for the construction of nanomaterials based on graphene oxide and conducting polymers, as well as the recent efforts made to apply this methodology in the development of sensors and biosensors.

“…Commonly applied coating methods to coat GO onto a substrate material before laser reduction includes drop casting [53][54][55][56][57], spin coating [58][59][60][61], electro-spray coating [62], electroplating [63,64] and even direct immersing [65][66][67]. Before coating, a sample needs to be entirely cleaned to remove oil, dirt and rust on the surface of J o u r n a l P r e -p r o o f -12-material to ensure good bonding quality.…”

Hydrogen embrittlement (HE) is an epidemic problem for high strength medium carbon low alloy steel causing reduction in mechanical strength and useful service lifetime. Hydrogen embrittlement of high strength steel is concern for various industrial components used in critical applications. Unpredictable & sudden failure of mechanical equipment/components made of high strength steel (HSS) below designed allowable stress and without appreciable deformation resulted in many catastrophic accidents. HSS being used in various engineering applications such as Aerospace, Nuclear, Marine and Transportation etc. Components typically affected by hydrogen embrittlement are pressure vessels, boilers, automobile frame, fasteners & hardware, shafts, axles, rotors, pipelines etc. Extensive research has been done by scientists & engineers to explore various ways to prevent hydrogen embrittlement. Some of them are i) addition of alloying elements ii) selection of material with less susceptibility to hydrogen iii) use of barrier layers to prevent hydrogen diffusion iv) change in manufacturing process and application environment v) use of advance Nano coatings to minimize hydrogen penetration etc. Out of all these methods of controlling hydrogen embrittlement, use of advance coatings appears to be more practical, less intricate and economical. In current decade Graphene has achieved a great attention from engineering world because of its excellent chemical, physical, mechanical & thermal properties. Graphene can act as a protective barrier against many environmental induced degradation of alloy steels because of its extraordinary impermeability. This review article summaries the current state of research & available commercial solutions for mitigations of hydrogen embrittlement using graphene based Nanocoatings. Authors have conducted experiments on several available coatings including graphene to investigate the behavior in an environment promoting hydrogen embrittlement and compared the effect on mechanical properties and ductility of high strength steel (EN24/AISI4340/34CrNiMo6)
