Structure, Orientation and Stability of Lysozyme Confined in layered Materials

Sébastien Balme, Régis Guégan, Jean-Marc Janot, Maguy Jaber, Mathilde Lepoitevin, Philippe Dejardin, Xavier Bourrat, Mikael Motelica-Heino

The confinement of lysozyme in 3 layered materials based on montmorillonite and lamellar double hydroxide exhibiting different surface charges was studied. The protein structure and orientation in these materials were determined by X-Ray diffraction, time resolved fluorescence and fluorescence…

Relantionship between the feedstock powders reactivity and the Electrochemical properties of 316L Stainless steel obtained by laser powder bed fusion

Alexis Fouchereau, Beatriz Puga, Hicham Maskrot, Fernando Lomello, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

3D printing by Laser-Powder Bed Fusion (L-PBF) is an innovative process using a high energy density laser to melt the raw material into a powder form. Previous studies have shown that the powder properties are crucial for the density, quality and microstructure of the materials produced [1, 2] but…

Influence of Large Magnetic Field Gradients at the Electrochemical Interface

Jinu Kurian, Peter Dunne, Vincent Vivier, Gwenael Atcheson, Ruslan Salikhov, Ciaran Fowley, Munuswamy Venkatesan, Olav Hellwig, Michael Coey, Bernard Doudin

We investigate how a model single-electron-exchange electrochemical reaction can be influenced by a magnetic field, B, which is a combination of an external applied field and the stray field generated by a Co/Pt multilayer thin film stack with preferred perpendicular magnetization. The Lorentz…

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…

Core–Shell Gold/Silver Nanoparticles for Localized Surface Plasmon Resonance-Based Naked-Eye Toxin Biosensing

Alexis Loiseau, Lu Zhang, David Hu, Michèle Salmain, Yacine Mazouzi, Raphaël Flack, Bo Liedberg, Souhir Boujday

The localized surface plasmon resonance (LSPR) phenomenon provides a versatile property for biodetection. Herein, this unique feature was employed to build a homogeneous optical biosensor to detect staphylococcal enterotoxin A (SEA) in solution down to very low levels by naked-eye readout. If the…

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…

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)…
