Journal ArticleDOI
Fabrication of highly ordered nanoporous thin Au films and their application for electrochemical determination of epinephrine
Ewa Wierzbicka,Grzegorz D. Sulka +1 more
TL;DR: In this article, the anodic oxidation of epinephrine (EP) on Au electrodes with a large surface area was studied in phosphate buffer solution (pH 7), and the results revealed that oxidation processes of EP are controlled by diffusion.
Journal ArticleDOI
Nanoporous spongelike Au–Ag films for electrochemical epinephrine sensing
Ewa Wierzbicka,Grzegorz D. Sulka +1 more
TL;DR: In this article, a simple strategy to fabricate an efficient electrochemical sensor for epinephrine (EP) oxidation is developed by selective etching of the electrodeposited thin Au-Ag alloyed film.
Journal ArticleDOI
Flash-PEO as an alternative to chromate conversion coatings for corrosion protection of Mg alloy
Ewa Wierzbicka,Bahram Vaghefinazari,Sviatlana V. Lamaka,Mikhail L. Zheludkevich,Marta Mohedano,Lara Moreno,Pieter Visser,A. Rodriguez,J. Velasco,Raul Arrabal,Endzhe Matykina +10 more
TL;DR: In this article, a flash-PEO coating is developed on AZ31B alloy in a combination of silicate, phosphate, and fluoride based electrolyte in order to offer a green alternative to chromate conversion coatings.
Journal ArticleDOI
Dewetting of PtCu Nanoalloys on TiO2 Nanocavities Provides a Synergistic Photocatalytic Enhancement for Efficient H2 Evolution.
Fahimeh Shahvaranfard,Paolo Ghigna,Alessandro Minguzzi,Ewa Wierzbicka,Patrik Schmuki,Patrik Schmuki,Marco Altomare +6 more
TL;DR: An improved robustness of PtCu nanoalloys against poisoning from methanol oxidation products such as CO is suggested, due to Pt-Cu electronic interactions, where Cu increases the electron density on Pt favoring a more efficient electron transfer for H2 evolution.
Journal ArticleDOI
Epinephrine sensing at nanostructured Au electrode and determination its oxidative metabolism
TL;DR: In this paper, a relatively simple method of fabrication of Au nanotube array electrodes for electrochemical determination of epinephrine (EP) was described, which could be easily transferred to non-laboratory conditions.
