Vibrating single probe and stationary bi-probes to measure local electrochemical impedance spectroscopy.

Hisasi Takenouti, G. Galicia, Michel Keddam, Vincent Vivier

The electrochemical impedance spectroscopy is widely used to investigate the electrode kinetics. This method is recognized as a powerful method to discriminate one reaction model to another and also to evaluate the reaction rate of elementary steps. However, when the electrode kinetics is markedly…

Nanostructured and spiky gold in biomolecule detection: improving binding efficiencies and enhancing optical signals

E. E. Bedford, S. Boujday, C.-M. Pradier, F. X. Gu

Nanostructured gold can improve the ability to detect biomolecules. Whether planar nanostructured surfaces or nanostructured particles are used, similar principles governing the enhancement apply. The two main benefits of nanostructured gold are improved geometry and enhancement of optical…

Corrosion and protection of high leaded tin bronze covered with patina in NaHCO3 + Na2SO4 solution simulating acid rain in urban environment

Kamal Rahmouni, Suzanne Joiret, Luc Robbiola, A. Srhiri, Hisasi Takenouti, Vincent Vivier

An experimental procedure for obtaining reproducible patina on high leaded tin bronze, B66 (Cu-8Sn-14Pb in wt %) has been devised, followed by its isolation from the substrate and examination of the electrochemical behaviour in a solution of 0.2 g.L - 1 Na 2 SO 4 + 0.2 g.L - 1 NaHCO 3 acidified to…

Catalytic Pyrolysis of Plastics over Maghemite-Impregnated Mesocellular Foam using Induction Heating

Luing Wong Syie, Sabino Armenise, B. Nyakuma Bemgba, Soon Ng Pang, Hau Lee Chia, Anna Bogush, Franck Launay, Evgeny Rebrov, Marta Munoz

Pyrolysis is a key technology that converts unrecyclable end-of-life plastics into value-added products. Nevertheless, the high energy consumption during plastic pyrolysis limits the economic feasibility of a scaled-up process. Development of an energy-efficient plastic pyrolysis process is…

Sustainable production of acrolein: effects of reaction variables, modifiers doping and ZrO2 origin on the performance of WO3/ZrO2 catalyst for the gas-phase dehydration of glycerol

Song-Hai Chai, Li-Zhi Tao, Bo Yan, Jacques C. Vedrine, Bo-Qing Xu

Zirconia-supported tungsten oxide (WO3/ZrO2 or WZ) is known as an efficient catalyst for selective acrolein (AC) production from gas-phase dehydration of glycerol (GL). Two catalysts (WZ-CP and WZ-AN) were prepared herein using, respectively, a ZrO(OH)2 hydrogel (ZrO(OH)2-CP) and its derived…

Laboratory simulation to support the search for organic molecules at the surface of Mars

Olivier Poch, Cyril Szopa, Patrice Coll, Maguy Jaber, Thomas Georgelin, Jean-Francois Lambert, Fabien Stalport

The search for organic carbon at the surface of Mars, as clues of past habitability or remnants of life, is a major science goal of Mars’ exploration. Understanding the chemical evolution of organic molecules under current Martian environmental conditions is essential to support the analyses…
