Corrosion behavior of stainless steel-tungsten carbide joints brazed with AgCuX (X = In, Ti) alloys

Analyzing imprecise graphene foam resistance data

“…This means that graphene is very advantageous for contacting the electrodes materials, used in the electrochemical systems and electric layers for different devices like capacitors, see (Zhang and Zhao 2009, Yan et al 2019, Qi et al 2021 etc. One can also find the electrochemical impedance test using the EIS as expressed in the following reference (Yan et al 2022). But we have not added this work due to the unavailability of technique.…”

Cu-Based Multicomponent Metallic Compound Materials as Electrocatalyst for Water Splitting

“…As depicted in Figure 3C , it can be found that the HER activity is also with a low overpotential of 215.8 mV at 10 mA/cm 2 for the Fe–Cu sample and 329.8 mV at 10 mA/cm 2 for the Co–Cu sample. The excellent electrochemical performance of all samples can be attributed to the improvement of fast charge transfer kinetics ( Yan et al, 2022 ), so electrochemical impedance spectroscopy (EIS) as a further research was carried out. As shown in Figure 3D , the charge transfer resistance of Co–Cu is also significantly smaller, illustrating the small electrode polarization and better electrochemical kinetics.…”

Anchoring Co3S4 nanowires on NiCo2O4 nanosheet arrays as high-performance electrocatalyst for hydrogen and oxygen evolution

“…From the TEM images, it can be seen that there are two struc- The above results reveal that there is strong electron interaction between Co, Fe, S and O after the formation of the heterostructure at the NiCo 2 O 4 / Co 3 S 4 heterostructure interface, and the potential interfacial electronic structure reconfiguration will be benefit to promote the electrocatalytic activity during water splitting. [46][47][48][49][50][51][52] After understanding the composition and structure of the catalysts, electrocatalytic activity of the catalysts was further analyzed. The HER performance of the catalysts was assessed in KOH (1 M) solution.…”
