The key parameters influencing the reactivity of magnesium silicate based catalysts : application to transesterification in liquid phase, Les paramètres clés influençant la réactivité de catalyseurs à base de silicate de magnésium : application à la transesterification en phase liquide

Longfei Lin

In the field of biomass derivatives valorisation, transesterification reactions have attracted numerous interest due to its importance to transform platform molecules. A study of the parameters governing the reactivity of magnesium silicate based catalyst in a model transesterification reaction was…, Dans le domaine de la valorisation des dérivés de la biomasse, les réactions de transestérification suscitent un grand intérêt en raison de leur importance pour transformer des molécules plateformes biobasées. L'étude des paramètres clés régissant une réaction de transestérification modèle,…

On-line inductively coupled plasma-atomic emission spectroelectrochemistry: Real-time element-resolved electrochemistry

Borhan Bin Mohamad Sultan, Oumaïma Gharbi, Kevin Ogle, Junsoo Han

Electrochemical techniques are coupled with inductively coupled plasma (ICP) atomic emission spectrometry for in-line electrolyte analyses. In this way, direct measurement of the elemental dissolution rates in real-time or element-resolved electrochemistry can be carried out, complementary to…

Insight into the mechanism of action of temporin-SHa, a new broad-spectrum antiparasitic and antibacterial agent

Zahid Raja, Sonia André, Feten Abbassi, Vincent Humblot, Olivier Lequin, Tahar Bouceba, Isabelle Correia, Sandra Casale, Thierry Foulon, Denis Sereno, Bruno Oury, Ali Ladram

Antimicrobial peptides (AMPs) are promising drugs to kill resistant pathogens. In contrast to bacteria, protozoan parasites, such as Leishmania, were little studied. Therefore, the antiparasitic mechanism of AMPs is still unclear. In this study, we sought to get further insight into this mechanism…

Enhancing low-temperature activity and durability of Pd-based diesel oxidation catalysts using ZrO2 supports

Mi-Young Kim, Eleni A. Kyriakidou, Jae-Soon Choi, Todd J. Toops, Andrew J. Binder, Cyril Thomas, James E. Parks, Viviane Schwartz, Jihua Chen, Dale K. Hensley

We investigated the impact of ZrO2 on the performance of palladium-based oxidation catalysts with respect to low-temperature activity, hydrothermal stability, and sulfur tolerance. Pd supported on ZrO2 and SiO2 were synthesized for a comparative study. Additionally, in an attempt to maximize the…

Biomass characterization and biogas production of pretreated straw: is there a correlation?

Vincenzo Calcagno, Shruthi Meenakshisundaram, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Claude Jolivalt, André Pauss, Xiaojun Liu

Lignocellulosic biomass is a very attractive substrate for biogas production via anaerobic digestion. Among all, straw represents a very interesting and worldwide diffused agricultural by-product. However, due to the intrinsically complex structure of lignocellulosic biomass, straw has low…

Deciphering interfacial capacitance of passive electrode : contribution of the double layer

Oumaïma Gharbi, Mai T.T. Tran, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the EIS response of passive film remains a difficult challenge since it usually results in a non-ideal behavior of the dielectric properties of the film and mainly relies on the assumption that the contribution of the double layer can be neglected. The later an approximation can be…

On the graphical analysis of the impedance response of passive electrodes

Mai T.T. Tran, Oumaïma Gharbi, Mark E Orazem, Bernard Tribollet, Mireille Turmine, Vincent Vivier

The analysis of the capacitive behavior of a passive electrode is often a difficult subject because the response obtained by electrochemical impedance spectroscopy (EIS) is characterized by a non-ideal behavior that we try to model by using a constant phase element (CPE) [1, 2]. In doing so, both…

Elaboration of antibiofilm surfaces functionalized with antifungal-cyclodextrin inclusion complexes.

Aïcha Gharbi, Vincent Humblot, Turpin Frédéric, Claire-Marie Pradier, Christine Imbert, Jean-Marc Berjeaud

To tackle the loss of activity of surfaces functionalized by coating and covalently bound molecules to materials, an intermediate system implying the noncovalent immobilization of active molecules in the inner cavity of grafted cyclodextrins (CDs) was investigated. The antifungal and antibiofilm…
