Evaluation of Gibbs Energy of Dioxouranium Transfer at an Electrified Liquid vertical bar Liquid Interface Supported on a Microhole

Hubert Girault, Astrid Johana Olaya Avendano, Manuel Alejandro Méndez Agudelo, Thomas James Stockmann, Zhifeng Ding

Herein is reported the determination of the Gibbs energy of dioxouranium (UO22+) transfer across an interface between two immiscible electrolytic solutions (ITIES), water and 1,2-dichloroethane, that was supported at a 25 mu m diameter microhole, by means ...

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

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

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 ...

Interfacial Photoreduction of Supercritical CO2 by an Aqueous Catalyst

Hubert Girault, Manuel Alejandro Méndez Agudelo, Patrick Voyame

Not just a solvent anymore: CO2 reduction under supercritical conditions was achieved in a biphasic water–supercritical CO2 system using an aqueous soluble catalyst (see picture). The introduction of such an interface provides a suitable reaction medium wh ...

Controlling the specific enrichment of multi-phosphorylated peptides on oxide materials: aluminium foil as a target plate for laser desorption ionization mass spectrometry

Hubert Girault, Liang Qiao, Mohamad Hojeij, Manuel Alejandro Méndez Agudelo, Hongyan Bi

A specific multi-phosphopeptide enrichment method is presented to complement current phosphopeptide isolation strategies that normally bias mass spectrometry analysis towards the detection of mono-phosphopeptides. An adsorption model is developed that show ...

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

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

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 ...

Formation and study of single metal ion–phospholipid complexes in biphasic electrospray ionization mass spectrometry

Hubert Girault, Daniel Filipe Dos Santos Alves Jana, Anne-Clémence Corminboeuf, Manuel Alejandro Méndez Agudelo, Michel Prudent

Single metal ion-phospholipid complexes are observed in biphasic electrospray ionization mass spectrometry (BESI-MS) using a dual-channel microsprayer. Such a microsprayer makes it possible to put into contact two immiscible liquids within the Taylor cone. ...

Voltammetric determination of extreme standard Gibbs ion transfer energy

Hubert Girault, Astrid Johana Olaya Avendano, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo

A voltammetric methodology to determine the standard Gibbs energy of transfer of highly hydrophobic and hydrophilic ions has been developed. The electrochemical cell used includes a water|1,2-dichloroethane micro-interface supported on a microhole in a thi ...

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

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

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 ...

Oxygen reduction catalyzed by a fluorinated tetraphenylporphyrin free base at liquid/liquid interfaces

Hubert Girault, Anne-Clémence Corminboeuf, Bin Su, Manuel Alejandro Méndez Agudelo, Imren Hatay, Zdenek Samec

The diprotonated form of a fluorinated free base porphyrin, namely 5-(p-aminophenyl)-10,15,20-tris(pentafluorophenyl)porphyrin (H(2)FAP), can catalyze the reduction of oxygen by a weak electron donor, namely ferrocene (Fc). At a water/1,2-dichloroethane in ...
