Introduction
I am an active researcher in both fundamental and applied engineering science with an expertise in the field of hybrid/inorganic membrane/material and surface chemistry. I am predominantly interested in the development and characterization of hybrid/inorganic membranes having a controlled pore structure and shape (2D/3D) with unique surface composition and properties in liquid nanofiltration, or gas separation.

Polyimide networks are key in the development of stable, resilient, and efficient membranes for separation applications under demanding conditions. To this aim, the controlled design of the network’s nanostructure and its properties are needed. However, such control remains a challenge with currently available synthesis methods. Here, we present a...

As nanofiltration applications increase in diversity, there is a need for new fabrication methods to prepare chemically and thermally stable membranes with high retention performance. In this work, thio-bromo "click" chemistry was adapted for the fabrication of a robust covalently attached and ultrathin nanofiltration membrane. The selective layer...

Small polyethylene glycol (PEG) molecules were grafted on ceramic γ-alumina membranes, by making use of organo-alkoxysilanes or organo-phosphonic acids as linking groups. It was proven by FTIR that the short PEG brushes are chemically grafted into the pores of a 5 nm γ-alumina mesoporous support, which results in a decrease of the pore diameter as...

Uniquely suited to organic solvent nanofiltration (OSN) are hybrid, ceramic-based membranes. The stability of these membranes in the harsh solvents and conditions of industrial process streams is due to the sturdy and inert architecture of the ceramic, while the organic functionalization is responsible for surface and pore properties of the membran...

Membranes consisting of uniform and vertically organized mesopores are promising systems for molecular filtration due to the possibility to combine high flux and high rejection properties. In this work, a new generation of mesoporous silica membranes (MSMs) has been developed, in which an organized mesoporous layer is directly formed on top of a po...

In this work we provide a detailed study on grafting reactions of various dialkylphosphonate-based ILs. Special attention has been devoted to a comprehensive investigation on how the nature of the anion and the organic spacer composition (hydrophilic or hydrophobic groups) could impact the grafting densities and bonding modes of phosphonate-based I...
Article
This work reports on a promising strategy for the development of novel Grafted Ionic Liquid Membranes (GILMs) in which phosphonate-based ILs are confined within the pores of a mesoporous γ-Al2O3 ceramic membrane by chemical grafting. The influence of both the chemical nature (i.e., alkyl versus ether) of the organic spacer chain and the presence of...
Thesis
In competition with amines, ionic liquids (ILs) are known to interact strongly and reversibly with acid gases, making supported IL-membrane (SILMs) versatile materials for use in CO2 membrane separation applications. It is possible to finely tune SILMs properties for CO2 adsorption/separation by tailoring the characteristics of both the support (e....

Imidazolium bromide-based ionic liquids bearing phosphonyl groups on the cationic part were synthesized and grafted on γ-alumina (γ-Al₂O₃) powders. These powders were prepared as companion samples of conventional mesoporous γ-alumina membranes, in order to favor a possible transfer of the results to supported membrane materials, which could be used...

Statement of significance: Benzoxaboroles are an emerging family of molecules which have attracted much attention in the biomedical field, notably for the design of new drugs. However, the way in which these molecules, once introduced in the body, may interact with bone mineral is still unknown, and the possibility of associating benzoxaboroles to...

Despite the extensive range of investigations on boronic acids (R-B(OH)2), some aspects of their reactivity still need to be explored. This is the case for the coordination chemistry of boronate anions (R-B(OH)3−), which has only recently been started to be studied. The purpose of this review is to summarize some of the key features of boronate lig...
