Nanoscale origins of super-capacitance phenomena
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
Common Principles of Molecular Electronics and Nanoscale Electrochemistry
(Amer Chemical Soc, 2018-06-19)
The merging of nanoscale electronics and electrochemistry can potentially modernize the way electronic devices are currently engineered or constructed. This Feature offers a conceptual discussion of this central topic, ...

Electrocatálisis en electrodos nano estructurados de plata
Los estudios realizados en este trabajo abarcan diferentes aspectos de la cinética de la reacción de desprendimiento de hidrógeno (her). Esto tiene como finalidad la obtención de nuevos conocimientos que permitan comprender ...
Pseudocapacitance phenomena and applications in biosensing devices
The concept of electrochemical capacitance comprises both double-layer grounded capacitive (non-faradaic charging) and pseudocapacitive (faradaic charging) behaviours, as has been recently demonstrated [1–3]. In this paper, ...
Measuring quantum conductance and capacitance of graphene using impedance-derived capacitance spectroscopy
Here, we demonstrate that impedance-derived capacitance spectroscopy is a useful method for measuring and analyzing the quantum of conductance and capacitance of a single-layer graphene sheet. Both quantum conductance and ...
Electrochemistry and first principles of quantum mechanics
In Chap. 1, we demonstrated that nanoscale electronics and electrochemistry both originate from the same physical background and are underpinned by chemical capacitance and its association with quantised relaxation resistance, ...
The limits of underpotential deposition in the nanoscale
(Elsevier Science Inc, 2012-07)
A thermodynamic model predicting the disappearance of the underpotential deposition phenomenon in the limit of small nanoparticles is proposed and developed for selected families of geometric bodies. The key parameters are ...
Electrochemically Generated Nanobubbles: Invariance of the Current with Respect to Electrode Size and Potential
(American Chemical Society, 2020-08)
Gas-producing electrochemical reactions are key to energy conversion and generation technologies. Bubble formation dramatically decreases gas-production rates on nanoelectrodes, by confining the reaction to the electrode ...
