Key Role of the Local Hydrophobicity in the East Patch of Plastocyanins on Their Thermal Stability and Redox Properties
(American Chemical Society, 2018)
Understanding the molecular basis of the thermal stability and functionality of redox proteins has important practical applications. Here, we show a distinct thermal dependence of the spectroscopic and electrochemical ...

Active role of the buffer in the proton-coupled electron transfer of immobilized iron porphyrins
(American Chemical Society, 2021-01)
Evaluation of the proton-coupled electron transfer thermodynamics of immobilized hemin is challenging due to the disparity of its electrochemical titration curves reported in the literature. Deviations from the one-electron, ...

The Fe (III)/Fe(II) redox couple as a probe of immobilized tobacco peroxidase: Effect of the immobilization protocol
(Elsevier, 2019-03)
Non-turnover voltammetry is a sensitive tool to characterize the electrochemical properties of redox proteins. However, the catalytically competent oxidation states of most peroxidases do not display the required electrochemical ...

Cobalt metal-organic framework based on layered double nanosheets for enhanced electrocatalytic water oxidation in neutral media
(American Chemical Society, 2020)
A new cobalt metal-organic framework (2D-Co-MOF) based on well-defined layered double cores that are strongly connected by intermolecular bonds has been developed. Its 3D structure is held together by π-π stacking interactions ...

Bimetallic Intersection in PdFe@FeOx-C Nanomaterial for Enhanced Water Splitting Electrocatalysis
(Wiley-Blackwell, 2022)
Supported Fe-doped Pd-nanoparticles (NPs) are prepared via soft transformation of a PdFe-metal oraganic framework (MOF). The thus synthesized bimetallic PdFe-NPs are supported on FeOx@C layers, which are essential for ...
