Electrospray ionization: an efficient approach to deposit polymetallic molecular switches onto gold surfaces

Amina Benchohra, Christophe Méthivier, Jessem Landoulsi, David Kreher, Rodrigue Lescouëzec

Electrospray ionization (EI) deposition is proven efficient in obtaining monolayers of a polymetallic charge transfer complex onto gold surfaces. The molecule's integrity is monitored by PM-IRRAS and XPS. This approach broadens the perspective of molecular magnetic switches' deposition,…

Probing the in-air growth of large area of 3D functional structures into a 2D supramolecular nanoporous network

Romain Brisse, Dominique Guianvarc'H, Christelle Mansuy, Sandrine Sagan, David Kreher, Lydia Sosa-Vargas, Lydia Hamitouche, Vincent Humblot, Imad Arfaoui, Vanessa Labet, Céline Paris, Christophe Petit, André-Jean Attias

Surface-confined host–guest chemistry at the air/solid interface is used for trapping a functionalized 3D Zn–phthalocyanine complex into a 2D porous supramolecular template allowing the large area functionalization of an sp2-hybridized carbon-based substrate as evidenced by STM, resonance Raman…

Surface-generated copper ions induce multilayer growth of small peptides

Jessem Landoulsi, Vincent Dupres, Christophe Méthivier, Ivan Leteyi Mfiban, Pauline Cornette, Elodie Colaço, Claire-Marie Pradier

Herein, we investigate the adsorption behavior of a small peptide, Glu-Cys-Gly, in aqueous solution onto copper surface and unravel a mechanism of growth of a hybrid peptide-copper multilayer the thickness of which may exceed a hundred of nanometers. Thanks to a combined set of surface…

Long-Lived Charge-Separated States in ZnS/Na-MOR Zeolite upon <i>trans</i>-Stilbene Adsorption

Pedro Henrique Morais Andrade, Matthieu Hureau, Anne-Sophie Mamede, Pascale Massiani, Alexandre Legrand, Alain Moissette

Electron transfer (ET) processes are of fundamental importance in many photochemical processes in biological and chemical systems. Here, semiconductor nanoparticles of ZnS (as electron relay) and trans-stilbene molecules (t-St) (as electron donor), both confined within the porous volume of…

Antibacterial properties of glycosylated surfaces: variation of the glucosidal moiety and fatty acid conformation of grafted microbial glycolipids

Claire Valotteau, Sophie Roelants, Dasaiyan Prabhu, Susanne Zibek, Michael Günther, Wim Soetaert, Bernd Everaert, Claire-Marie Pradier, Florence Babonneau, Niki Baccile, Vincent Humblot

Glycosylated surfaces can display antimicrobial properties. It has been shown that sophorolipids can be used to develop biocidal coatings against Gram-positive and Gram-negative bacteria, but with a limited efficiency so far. Therefore, it appears necessary to further investigate the surface…

Activation of C‐H Bond of Propane by Strong Basic Sites Generated by Bulk Proton Conduction on V‐Modified Hydroxyapatites for the Formation of Propene

Sarah Petit, Cyril Thomas, Yannick Millot, Jean-Marc Krafft, Christel Laberty-Robert, Guylène Costentin

Insights into the catalytic transformation of propane to propene on V‐apatites catalysts are provided based on structure‐reactivity relationships. Substitution of phosphates by vanadates in the hydroxyapatite structure leads to the formation of Ca10(PO4)6‐x(VO4)x(OH)2‐yOy V‐oxy‐hydroxy‐apatite…

Enhancement of water remediation by innovative photocatalytic luminous textiles reactor: Performance, kinetic modeling, and mechanistic insights

Sarra Karoui, Aymen Amine Assadi, Achraf Ghorbal, Lotfi Khezami, Achraf Assadi, Sivachandiran Loganathan, Abdeltif Amrane

To address wastewater treatment, a photocatalytic process using luminous-textile has been proposed due to its high efficiency and non-toxicity. In the present work, the photodegradation of Ciprofloxacin (CIP) in the liquid phase was studied in a compact reactor with a luminous-textile catalyst in…

Site-specific grafting on titanium surfaces with hybrid temporin antibacterial peptides

Nicolas Masurier, Jean-Baptiste Tissot, Douae Boukhriss, Said Jebors, Coline Pinese, Pascal Verdié, Muriel Amblard, Ahmad Mehdi, Jean Martinez, Vincent Humblot, Gilles Subra

Relying on a membrane-disturbing mechanism of action and not on any intracellular target, antimicrobial peptides (AMP) are attractive compounds to be grafted on the surface of implantable materials such as silicone catheters or titanium surgical implants. AMP sequences often display numerous…

Development of acidic sites in WOx/ZrO2

Thomas Onfroy, Guillaume Clet, Marwan Houalla

Evidence is shown of the appearance of Brønsted acidic sites in WOx/ZrO2 at a given W loading and of a direct correlation between the abundance of ‘strong’ Brønsted acidic sites in these catalysts and propan-2-ol decomposition activity.
