Electrical surface properties of nanoporous alumina membranes: influence of nanochannels’ curvature, roughness and composition studied via electrokinetic experiments

Ali Vakilinejad, Emmanuelle Dubois, Laurent Michot, Marie Jardat, Didier Lairez, Serge Durand-Vidal, Clément Guibert, Nicolas Jouault

Among classical nanoporous oxide membranes, anodic aluminum oxide (AAO) membranes, made of non-connected, parallel and ordered nanochannels, are very interesting nanoporous model systems widely used for multiple applications. Since most of these applications involve local phenomena at the…

Hybrid Hydrophobin/Gold Nanoparticles: Synthesis and Characterization of New Synthetic Probes for Biological Applications

Jane Politi, Luca de Stefano, Paola Giardina, Sandra Casale, Ilaria Rea, Jolanda Spadavecchia

We report a simple and original method to synthesize gold nanoparticles in which a fungal protein, the hydrophobin Vmh2 from Pleurotus ostreatus, mixed to cetyltetrammonium bromide (CTAB) has been used as additional component in a one-step synthesis, leading to shell-like hybrid protein-metal…

Enzyme Immobilization on Silane-Modified Surface through Short Linkers: Fate of Interfacial Phases and Impact on Catalytic Activity

Nesrine Aissaoui, Latifa Bergaoui, Souhir Boujday, Jean-François Lambert, Christophe Méthivier, Jessem Landoulsi

We investigated the mechanism of enzyme immobilization on silanized surfaces through coupling agents (cross-linkers) in order to understand the role of these molecules on interfacial processes and their effect on catalytic activity. To this end, we used a model multimeric enzyme (G6PDH) and several…

Salt concentration and pH-dependent adsorption of two polypeptides on planar and divided alumina surfaces; in situ IR investigations.

Claire-Marie Pradier, Vincent Humblot, Lorenzo Stievano, Christophe Méthivier, Jean-François Lambert

The adsorption of proteins is the first process to take place when a solid is immersed in a biological fluid; though not yet thoroughly understood at a molecular level, this process is also known to be strongly influenced by the presence of salt in solution or by pH changes. In the present work,…

Acidic Properties of Alkaline-Earth Phosphates Determined by an Experimental-Theoretical Approach

E. Blanco, Q. Gu, J. Couble, L. Martin, T. Onfroy, G. Costentin, Jean-Francois Paul, Carine Michel, S. Loridant

Alkaline-earth phosphates efficient in the dehydration of lactic acid to acrylic acid were previously shown to contain a surface mono/dihydrogen phosphate amorphous layer composed of M2+ cations and both P═O and POH groups. In this work, acidic properties of such a layer were determined combining…

Cu segregation in Au–Cu nanoparticles exposed to hydrogen atmospheric pressure: how is fcc symmetry maintained?

Q. Wang, A. Nassereddine, D. Loffreda, C. Ricolleau, D. Alloyeau, C. Louis, L. Delannoy, J. Nelayah, H. Guesmi

In a recent work [A. Nassereddine et al., Small 2021, 17, 2104571] we reported the atomic-scale structure and dynamics of sub-4 nm sized Au nanoparticles (NPs) supported on titania in H2 at atmospheric pressure obtained by using aberration-corrected environmental transmission electron microscopy (…

Introduction to Clay–Polymer Nanocomposites (CPN)

F Bergaya, Christian Detellier, Jean-François Lambert, G Lagaly

Clay mineral–polymer nanocomposites were described for the first time in 1993. Since that date, they were the subject of thousands of research papers. Clay mineral–polymer nanocomposites must be carefully distinguished from microcomposites and intercalated composites. The following chapters…

Ordered Nanostructures on a Hydroxylated Aluminum Surface through the Self-Assembly of Fatty Acids.

Irma Liascukiene, Nesrine Aissaoui, Svajus J. Asadauskas, Jessem Landoulsi, Jean-François Lambert

We investigate the mechanism of self-assembly of fatty acids (FA) and methyl oleate on an Al oxy-hydroxide surface with a view to deciphering the role and nature of interfacial processes (adsorption, chemical binding, molecular organization, etc.). For this purpose, we focus on parameters related…
