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…

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…

Improved Experimental Setup to Reach a Broad Frequency Domain in Local Electrochemical Impedance Spectroscopy Measurements

Maurilio Pereira Gomes, Samantha Michelle Gateman, Isolda Costa, Oumaïma Gharbi, Kieu Ngo, Jesualdo Luiz Rossi, Mireille Turmine, Vincent Vivier

We report a new experimental setup enabling local electrochemical impedance spectroscopy (LEIS) measurements over a wide frequency range, including the low frequency domain. First, an improved signal treatment was performed using a potential shifter to minimize the DC component of the measured…

Effect of Coverage and Defects on the Adsorption of Propanethiol on Au(111) Surface: A Theoretical Study

Noelia B. Luque, Elizabeth Santos, Juan Andres, Frederik Tielens

Periodic density functional calculations have been carried out to investigate both the thiol adsorption on Au(111) surface and the reaction mechanism for the formation of the self-assembled monolayers, taking propanethiol as a representative example. The effect of coverage and surface defects (…

In situ observation of atomic redistribution in alloying gold-silver nanorods

Jessi E S van Der Hoeven, Tom a J Welling, Tiago a G da Silva, Jeroen E van den Reijen, Camille La Fontaine, Xavier Carrier, Catherine Louis, Alfons van Blaaderen, Petra E de Jongh

The catalytic performance and optical properties of bimetallic nanoparticles critically depend on the atomic distribution of the two metals in the nanoparticles. However, at elevated temperatures, during light induced heating or during catalysis atomic redistribution can occur. Measuring such metal…

Ni-Silica-based Catalysts for CH4 Reforming by CO2 with Enhanced Stability: Recent Designs and the Impacts of Ni Confinement, Promoters, and Core-Shell Structures

Oscar Daoura, Maya Boutros, Franck Launay

CO2 reforming of CH4, also referred to as the Dry Reforming of Methane (DRM), is considered an excellent method to produce H2 and CO (syngas), which are known to be used for the production of higher alkanes and oxygenates. Despite nickel’s moderate toxicity, Ni-based heterogeneous catalysts are…
