Electronic and structural characterization of barrier-type amorphous aluminium oxide

Patrik Schmutz, Alfredo Pasquarello, Claudia Cancellieri, Raheleh Partovi Nia, Fabio Evangelisti, Francesco Ambrosio, Roland Hauert

The structural, electronic, and dielectric properties of barrier -type anodic Al oxides prepared with various thicknesses have been investigated. The planar and cross morphologies as well as the surface charge distribution were investigated as a function o ...

Study of Amyloid beta-Peptide (A beta 12-28-Cys) Interactions with Congo Red and beta-Sheet Breaker Peptides Using Electrochemical Impedance Spectroscopy

Hubert Girault, Raheleh Partovi Nia

A surface-based approach is presented to study the interactions of A beta 12-28-Cys assembled on gold surfaces with Congo red (CR) and a beta-sheet breaker (BSB) peptide. The various aspects of the peptide film have been examined using different electroche ...

Ionic partition diagram of tetraphenylporphyrin at the water|1,2-dichloroethane interface

Hubert Girault, Zdenek Samec, Bin Su, Raheleh Partovi Nia, Manuel Alejandro Méndez Agudelo

diagram of 5,10,15,20-tetraphenyl-21H,23H-porphine (H2TPP) at the water|1,2-dichloroethane interface using a simple Born solvation model. This zone diagram shows under which form this porphyrin is present, i.e. neutral, monoprotonated or diprotonated, and ...

Electrocatalysis at liquid/liquid interfaces

Raheleh Partovi Nia

This thesis is devoted to the study of oxygen reduction reaction catalysed by porphyrins at the interface between two immiscible electrolyte solutions (ITIES). Electrochemical and spectrophotometric techniques are introduced to these interfaces in order to ...

Oxygen reduction by decamethylferrocene at liquid/liquid interfaces catalyzed by dodecylaniline

Hubert Girault, Zdenek Samec, Bin Su, Raheleh Partovi Nia, Manuel Alejandro Méndez Agudelo, Imren Hatay

Molecular oxygen (O2) reduction by decamethylferrocene (DMFc) was investigated at a polarized water/ 1,2-dichloroethane (DCE) interface. Electrochemical results point to a mechanism similar to the EC type reaction at the conventional electrode/solution int ...

Dioxygen Reduction by Cobalt(II) Octaethylporphyrin at Liquid / Liquid Interfaces

Hubert Girault, Zdenek Samec, Bin Su, Raheleh Partovi Nia, Manuel Alejandro Méndez Agudelo

Oxygen reduction catalyzed by cobalt(II) (2,3,7,8,12,13,17,18-octaethylporphyrin) [Co(OEP)] at soft interfaces is studied by voltammetry and biphasic reactions. When Co(OEP) is present in a solution of 1,2-dichloroethane in contact with an aqueous acidic s ...

Proton Pump for O2 Reduction Catalyzed by 5,10,15,20- Tetraphenylporphyrinatocobalt(II)

Hubert Girault, Zdenek Samec, Bin Su, Raheleh Partovi Nia, Fengping Li

The role of 5,10,15,20-tetraphenylporphyrinatocobalt(II) ([Co-(tpp)]) as a catalyst on molecular oxygen (O2) reduction by ferrocene (Fc) and its two derivatives, 1,1’-di-methylferrocene (DFc) and decamethylferrocene (DMFc) at a polarized water¦1,2-dichloro ...

Hydrogen Evolution at Liquid–Liquid Interfaces

Hubert Girault, Bin Su, Raheleh Partovi Nia, Xile Hu, Imren Hatay, Heron Vrubel

Blowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2-dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequen ...

Detection of hydrogen peroxide produced at a liquid/liquid interface using scanning electrochemical microscopy

Hubert Girault, Bin Su, Raheleh Partovi Nia, Fernando Cortes Salazar

Scanning electrochemical microscopy (SECM) was used to monitor in situ hydrogen peroxide (H2O2) produced at a polarized water/1,2-dichloroethane (DCE) interface. The water/DCE interface was formed between a DCE droplet containing decamethylferrocene (DMFc) ...

H2O2 generation by decamethylferrocene at a liquid | liquid interface

Hubert Girault, Michel Prudent, Zdenek Samec, Bin Su, Mohamad Hojeij, Raheleh Partovi Nia, Anne-Clémence Corminboeuf

Hydrogen peroxide generation at a liquid|liquid interface occurs with a yield of 20 % with respect to the concentration of reducing agent (decamethylferrocene). The liquid|liquid interface supplies electrons from the reducing agent and protons from the aqu ...

Evidence of tetraphenylporphyrin monoacids by ion-transfer voltammetry at polarized liquid|liquid interfaces

Hubert Girault, Zdenek Samec, Bin Su, Raheleh Partovi Nia

We present a simple methodology to illustrate the existence of tetraphenylporphyrin monoacid based on ion-transfer voltammetry at a polarized water|1,2-dichloroethane interface and organic pK values are also estimated. ...
