To remedy the problems caused by the introduction of an additional electron mediator and realize signal amplification, a new strategy has been presented to construct an electrochemical aptasensor for thrombin detection based on the cascade electrocatalysis of alkaline phosphatase (ALP) and Pt nanoparticle (PtNP)-functionalized ZnO nanoflowers.

Arrays of aligned multi-walled carbon nanotube-ionic liquid (MIL) were assembled on silicon wafers (Si-MIL). Formation of Si-MIL was confirmed by FTIR, AFM and Raman techniques. The electrochemical measurements indicated that Si-MIL showed good electrocatalysis towards oxygen reduction compared with MIL drop-cast on a glassy carbon electrode.

In this paper, the main characteristics of ethanol electrooxidation are presented and the results of electrochemical and spectroscopic methods are discussed. The total oxidation reaction should produce 12 e/molecule. However, on Pt catalysts, the reaction follows parallel pathways forming acetaldehyde, acetic acid and carbon dioxide as soluble products. Thus much lower yields of charge per etha...

The past two decades have seen a renewed and rapidly growing interest in the fields of electrochemistry and electrocatalysis. This is on the one hand stimulated by applications in energy conversion and energy storage, where highly efficient electrochemical/electrocatalytic processes are considered to be an indispensable part of modern energy concepts based on the use of renewable energy sources...

Macroscale and nanoscale measurements of epinephrine electro-oxidation at graphite electrodes, with different step edge densities, demonstrate unequivocally that the reaction occurs readily at the basal surface, and that step edges are not required for molecular electrocatalysis, in contrast to the current literature model.

The pyridine-rich complex [NiII(LN2Py3)(MeCN)](ClO4)2 (1) acts as an efficient electro- and photocatalyst in the generation of H2 from water. Observed TONs reach 1050 for electrocatalysis and a remarkable 3500 for photocatalysis. Experimental and DFT data support the ligand-reduced [NiIL˙] as the catalytically active species, contrasting with the [CoIL] observed for cobalt catalysts.

Escherichia coli with direct electron transfer, a direct electrochemistry behavior in electrocatalysis of microbial fuel cells, underwent statistically significant up- and down-regulation of 107 genes, which suggests that the underlying cellular mechanisms include the regulation of outer membrane porin genes and terminal oxidase genes.
