C3-Alkylation of furfural derivatives by continuous flow homogeneous catalysis

Grédy Kiala Kinkutu, Catherine Louis, Myriam Roy, Juliette Blanchard, Julie Oble

The C3-functionalization of furfural using homogeneous ruthenium catalysts requires the preinstallation of an ortho -directing imine group, as well as high temperatures, which did not allow scaling up, at least under batch conditions. In order to design a safer process, we set out to develop a…

Covalent Grafting of Polyoxometalate Hybrids onto Flat Silicon/Silicon Oxide: Insights from POMs Layers on Oxides

Maxime Laurans, Kelly Trinh, Kevin Dalla Francesca, Guillaume Izzet, Sandra Alves, Etienne Derat, Vincent Humblot, Olivier Pluchery, Dominique Vuillaume, Stéphane Lenfant, Florence Volatron, Anna Proust

Immobilization of polyoxometalates (POMs) onto oxides is relevant to many applications in the fields of catalysis, energy conversion/storage, or molecular electronics. Optimization and understanding the molecule/oxide interface is crucial to rationally improve the performance of the final molecular…

Revisiting the Mukaiyama-type epoxidation for the conversion of styrene into styrene carbonate in the presence of O 2 and CO 2

Matthieu Balas, Asma Mayoufi, Richard Villanneau, Franck Launay

Since its first report in the early 1990s, Mukaiyama-type aerobic epoxidation involving the presence of an aldehyde as an electron donor is considered as an interesting oxidation reaction. Among the various metal catalysts efficient for this process, salen-type complexes have many advantages: i)…

Hollow Gold Nanoshells for Sensitive 2D Plasmonic Sensors

Daoming Sun, Ferdaous Ben Romdhane, Axel Wilson, Michèle Salmain, Souhir Boujday

The interaction of incident light with noble metal nanoparticles engenders a fascinating phenomenon known as localized surface plasmon resonance (LSPR). This results in the presence of single or multiple intense absorption bands in the visible to near-infrared spectral range whose position is…

Interactions of Calcium with Chlorogenic and Rosmarinic Acids: An Experimental and Theoretical Approach

Estelle Palierse, Cédric Przybylski, Dalil Brouri, Claude Jolivalt, Thibaud Coradin

Chlorogenic (CA) and rosmarinic (RA) acids are two natural bioactive hydroxycinnamic acids whose antioxidant properties can be modulated by the chelation of metal ions. In this work, the interactions of these two carboxylic phenols with calcium ions and the impact of such interactions on their…

Charge transport through redox active [H₇P₈W₄₈O₁₈₄]^33- polyoxometalates self-assembled onto gold surfaces and gold nanodots

K. Dalla Francesca, Stéphane Lenfant, M. Laurans, F. Volatron, G. Izzet, Vincent Humblot, C. Methivier, David Guérin, A. Proust, Dominique Vuillaume

Polyoxometalates (POMs) are redox-active molecular oxides, which attract growing interest for their integration into nano-devices, such as high-density data storage non-volatile memories. In this work, we investigated the electrostatic deposition of the negatively charged [H7P8W48O184]33− POM onto…

Design of TiO2/Au nanoparticle films with controlled crack formation and different architectures using a centrifugal strategy

Abdelhafed Taleb, Frederic Mesguich, Thomas Onfroy, Xue Yanpeng

Here we present an approach to design hybrid nanocomposite films based on TiO2/Au nanoparticles using centrifugation processes. The prepared nanocomposite films have been characterized by different techniques such as FEGSEM, TEM, BET and XRD. Furthermore it is demonstrated that centrifugal force…
