Two-Dimensional Layers of Colloidal CdTe Quantum Dots: Assembly, Optical Properties, and Vibroelectronic Coupling

Thomas Noblet, Souhir Boujday, Christophe Methivier, Marie Erard, Julie Hottechamps, Bertrand Busson, Christophe Humbert

The manufacturing of silica platforms functionalized by CdTe quantum dots (QDs) of 3.4 nm diameter through (3-aminopropy)triethoxysilane (APTES) aliphatic organosilanes is performed to preserve QDs excitonic properties after their transfer from colloidal solutions to surfaces at ambient air. In…

Mechanistic Study of Cast and 3D-Printed Stainless Steel Electropolishing in Acid Media and Deep Eutectic Solvents

Chloé Rotty, Marie-Laure Doche, Audrey Mandroyan, Vincent Vivier, Jean-Yves Hihn

The mechanistic analysis of the electropolishing procedure of stainless steel (SS) was revisited using electrochemical impedance spectroscopy. Firstly, the control of the dissolution reaction by diffusion was confirmed with the linear dependence of the limiting current density as a function of the…

Revealing the Band Structure of FAPI Quantum Dot Film and Its Interfaces with Electron and Hole Transport Layer Using Time Resolved Photoemission

Dylan Amelot, Prachi Rastogi, Bertille Martinez, Charlie Gréboval, Clément Livache, Francesco Andrea Bresciani, Junling Qu, Audrey Chu, Mayank Goyal, Sang-Soo Chee, Nicolas Casaretto, Xiang Zhen Xu, Christophe Méthivier, Hervé Cruguel, Abdelkarim Ouerghi, Angshuman Nag, Mathieu G Silly, Nadine Witkowski, Emmanuel Lhuillier

Lead halide perovskite nanocrystals have attracted attention in the field of nanocrystal-based light-emitting diode and solar cells, because their devices showed high performances in only a few years. Among them, CsPbI3 is a promising candidate for solar cell design in spite of a too wide band gap…

Halide Ligands to Release Strain in Cadmium Chalcogenide Nanoplatelets and Achieve High Brightness

Marion Dufour, Junling Qu, Charlie Gréboval, Christophe Méthivier, Emmanuel Lhuillier, Sandrine Ithurria

Zinc blende II-VI semiconductor nanoplatelets (NPLs) are defined at the atomic scale along the thickness of the nanoparticle and are initially capped with carboxylates on the top and bottom [001] facets. These ligands are exchanged on CdSe NPLs with halides that act as X-L-type ligands. These CdSe…

Investigation of an Allergen Adsorption on Amine- and Acid-Terminated Thiol Layers: Influence on Their Affinity to Specific Antibodies

P. Thebault, Souhir Boujday, Helene Senechal, Claire-Marie Pradier

This work describes the controlled immobilization of a recognized allergen, beta-lactoglobulin, onto gold transducers with the aim of optimizing the elaboration of a biosensor directed against allergen-produced antibodies. This protein was immobilized on both amine- and acid-terminated thiol self-…

Preparation of Highly Anisotropic Cobalt Ferrite/Silica Microellipsoids Using an External Magnetic Field

Sébastien Abramson, Vincent Dupuis, Sophie Neveu, Patricia Beaunier, David Montero

Magnetic cobalt ferrite/silica microparticles having both an original morphology and an anisotropic nanostructure are synthesized through the use of an external magnetic field and nanoparticles characterized by a high magnetic anisotropy. The association of these two factors implies that the ESE (…

Increasing the efficiency of magnetic heterogeneous Fenton catalysts with a simple halogen visible lamp

Nassira Ferroudj, Delphine Talbot, Aude Michel, Anne Davidson, Sébastien Abramson

The effect of a simple visible halogen lamp was studied in the Fenton-type oxidation of three model aqueous pollutants differing in their structure and electrostatic charge, methylorange (MO), methylene blue (MB) and paranitrophenol (PNP), using maghemite nanoparticles (γ-Fe 2 O 3 NP), or maghemite…

Investigating the Mukaiyama-type epoxidation reaction of alkenes with Cr(III) salophen catalysts: A confrontation between experiments and DFT calculations

Arnaud Marvilliers, Jean-Baptiste Harlé, Franck Launay, Sébastien Blanchard, Anne Gauvin-Bialecki, Hélène Gérard, Richard Villanneau

This study aimed at the complete elucidation of the mechanism of the Mukaiyama-type alkene epoxidation reaction using the [(salophen)CrIIICl] precatalyst, by combining spectroscopic (UV–visible and EPR) studies, catalytic reactivity and quantum chemical modeling. These studies performed in parallel…
