Tuning the load in gold and magnetic nanoparticles in nanogels through their design for enhanced dual magneto-photo-thermia

Esther Cazares-Cortes, Claire Wilhelm, Jose Efrain Perez, Ana Espinosa, Sandra Casale, Aude Michel, Ali Abou-Hassan, Christine Ménager

We describe a novel synthesis allowing to enhance the load in magnetic nanoparticles and gold nanorods in nanogels. Two different structures, simple cores and core-shells were synthesized and their heating properties upon alternating magnetic field or laser exposure are compared. Remarkably, the…

Approach for Plasmonic Based DNA Sensing: Amplification of the Wavelength Shift and Simultaneous Detection of the Plasmon Modes of Gold Nanostructures

Jolanda Spadavecchia, Alexandre Barras, Joël Lyskawa, Patrice Woisel, William Laure, Claire-Marie Pradier, Rabah Boukherroub, Sabine Szunerits

In this article, the detection of DNA hybridization taking advantage of the plasmonic properties of gold nanostructures is described. The approach is based on the amplification of the wavelength shift of a multilayered localized surface plasmon resonance (LSPR) sensor interface upon hybridization…

Synthesis and characterization of Ag-Protoporphyrin nano structures using mixed co-polymer method

Ramesh Perumal, Sandra Casale, Luca de Stefano, Jolanda Spadavecchia

In this paper, we report the synthesis of hybrid silver nanostructures (AgNPs) based on an effective mixing of polyols with Polyvinylpyrrolidone (PVP) and Porphyrin molecules, in particular Protoporphyrin IX (PP). The combination of PVP and PP, which act as co-directing agents and favour the…

Introduction of Co into the Vacant T-Atom Sites of SiBEA Zeolite as Isolated Mononuclear Co Species

Rafal Baran, Thomas Onfroy, Sandra Casale, Stanislaw Dzwigaj

A CoSiBEA zeolite was obtained by a postsynthesis method which consisted of a treatment of tetraethylammonium BEA zeolite with nitric acid in the first step and introduction of Co ions into the vacant T atom sites of the SiBEA zeolite by reaction of aqueous Co(NO3)2 solution with silanol groups.…

Molecular Understanding of the Bulk Composition of Crystalline Nonstoichiometric Hydroxyapatites: Application to the Rationalization of Structure-Reactivity Relationships

Manel Ben Osman, Jean Marc Krafft, Yannick Millot, Frederic Averseng, Tetsuya Yoshioka, Jun Kubo, Guylène Costentin

Crystalline hydroxyapatite samples (HAps) have been prepared by using the co-precipitation method under various pH conditions, leading to nonstoichiometric solids (1.65 < Ca/P < 1.77). The aim of this study was to rationalize the sensitivity of the catalytic activity of HAps to their bulk…

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…

Phosphoribosyl Pyrophosphate: A Molecular Vestige of the Origin of Life on Minerals

Mariame Akouche, Maguy Jaber, Marie-Christine Maurel, Jean-François Lambert, Thomas Georgelin

In this contribution, we report the formation under prebiotic conditions of phosphoribosyl pyrophosphate (PRPP) as a molecular precursor in the one-pot synthesis of a canonical nucleotide, namely adenosine monophosphate (AMP) from its building blocks (KH2PO4 or Pi, adenine, and d-ribose), on a…

Ultra-Compact Electrical Double Layers at TiO₂ (110) Electrified Interfaces

Immad Nadeem, Christopher Penschke, Ji Chen, Xavier Torrelles, Axel Wilson, Hadeel Hussain, Gregory Cabailh, Oier Bikondoa, Jameel Imran, Christopher Nicklin, Robert Lindsay, Jörg Zegenhagen, Matthew Blunt, Angelos Michaelides, Geoff Thornton

Metal-oxide aqueous interfaces are important in areas as varied as photocatalysis and mineral reforming. Crucial to the chemistry at these interfaces is the structure of the electrical double layer formed when anions or cations compensate for the charge arising from adsorbed H<sup>+</sup…

Effect of the order of Ni and Ce addition in SBA-15 on the activity in dry reforming of methane, Effet de l'ordre d'ajout du Ni et du Ce dans SBA-15 sur l'activité en reformage à sec du methane

Marie-Nour Kaydouh, Nissrine El Hassan, Anne Davidson, Sandra Casale, Pascale Massiani

Dry reforming of methane has been carried out on SBA-15 catalysts containing 5 wt% Ni and 6 wt% Ce. The effect of the order of Ni and Ce impregnation on the catalytic activity has been studied. Both metals were added using the “two-solvent” method that favors metal dispersion inside the pores.…
