Electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. An electro-active redox molecule comprises the main part of the electrochemical-based sensors. Ferrocene is one of the most popular redox molecule used in biosensor fabrication. But, instability of ferrocenium ion in strong nucleophilic reagents...

in this study ptfeco ternary alloys nanoparticles of three dimentional (3d) rhombus shapes dispersed on graphene nanosheets (ptfeco/gr) were successfully prepared and studied as electrocatalysts for oxygen reduction reaction (orr) in polymer-electrolyte fuel cells. a combination of analytical techniques including powder x-ray diffraction, x-ray photoelectron spectra, inductively coupled plasma-...

In the context of highly efficient, non-toxic and natural organic corrosion inhibitors, Phyllogorgia dilatata was studied as an anticorrosive for mild steel in acid medium. The marine octocoral crude extract (PDCE) was characterized and analyzed by LC-HRMS, revealing the presence of 16 different organic molecules. The corrosion inhibition was evaluated via weight loss study and electrochemical ...

The governing reaction mechanisms, and the electrode material compositions and structures, that controls the efficiency of the solid oxide fuel cells (SOFC) and solid oxide electrolysis cells (SOEC) need to be identified and well-understood for significant technological improvements. Our study on the oxygen electrodes focuses on specifically the effect of electrode crystal structure and morphol...
