Elucidation of the low coverage chiral adsorption assembly of L-lysine on Cu(110) surface: A theoretical study

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier

The adsorption of L-lysine on Cu(110) surface was studied using periodic DFT. The geometry is discussed in terms of the molecular electrostatic interactions, and electronic properties such as DOS. An STM image was simulated and compared with our recently obtained experimental results. Compelling…

Leucine on Silica: A Combined Experimental and Modeling Study of a System Relevant for Origins of Life, and the Role of Water Coadsorption

Hagop Abadian, Pauline Cornette, Dominique Costa, Alberto Mezzetti, Christel Gervais, Jean-François Lambert

Leucine on silica constitutes an interesting system from the point of view of origins of life studies since leucine coadsorbed on SiO2 together with glutamic acid can give rise to rather long linear polypeptides upon activation. It is also an ideal system to test methods of molecular…

Production and Characterization of Activated Carbon from Orange Peels by Chemical Activation with Sulfuric Acid

Sami Guiza, Salwa Hajyahia, Franck Launay, Mohamed Bagane

Oranges represent 75% of the total citrus fruits (Guiza in Ecol Eng, 99: 134–140, 2017) throughout the world, and Tunisia is one of the major juice producers. Orange peels could cause a significant disposal problem but they are also valuable biomass wastes (Valdes et al. in Langmuir 18: 2111–2116,…

Photoelectrochemical properties of ZnS- and CdS-TiO 2 nanostructured photocatalysts: Aqueous sulfidation as a smart route to improve catalyst stability

Samiha Chaguetmi, Larissa Chaperman, Sophie Nowak, Delphine Schaming, Stephanie Lau-Truong, Philippe Decorse, Patricia Beaunier, Cyrille Costentin, Fayna Mammeri, Slimane Achour, Souad Ammar

ZnS- and CdS-TiO2 hetero-nanostructures were synthesized by impregnation of polyol-made ZnS, CdS quantum dots (QDs) on the surface of TiO2 nanofibers that were grown on Ti sheets by controlled corrosion. Due to their finite size, the grafted QDs were partly oxidized, when air exposed, reducing…

Cristallisation de nanoparticules d'oxydes (MnO2, Co3O4, gamma-Fe2O3) dans les mésopores de silices

Anne Davidson, Vincent Dupuis, Regine Perzynski, Nissrine El Hassan, Marianne Imperor-Clerc, Dominique Bazin, Patricia Beaunier, Marie Dominique Appay

Du fait du grand nombre d'atomes exposés sur leur surface et de propriétés redox particulières, des nanoparticules d'oxydes de métaux de transition pourraient avantageusement remplacer les métaux nobles pour la gestion de problèmes environnementaux (élimination de CO à basse température,…

Macroscopic Magnetic Anisotropy Induced by the Combined Control of Size, Shape and Organization of NiFe Prussian Blue Analog Nanoparticles in an Ordered Mesoporous Silica Monolith

Robinson Moulin, Giulia Fornasieri, Marianne Impéror-Clerc, Eric Rivière, Patricia Beaunier, Anne Bleuzen

Integration of coordination polymers and metal–organic frameworks into real applications requires a processing step at the nanoscale. However, their synthesis in the form of nanoparticles with controlled size, shape and organization remains a challenge faced by diverse scientific communities.…

Sensing the Charge State of Single Gold Nanoparticles via Work Function Measurements

Yingjie Zhang, Olivier Pluchery, Louis Caillard, Anne-Félicie Lamic-Humblot, Sandra Casale, Yves J. Chabal, Miquel Salmeron

Electrostatic interactions at the nanoscale can lead to novel properties and functionalities that bulk materials and devices do not have. Here we used Kelvin probe force microscopy (KPFM) to study the work function (WF) of gold nanoparticles (NPs) deposited on a Si wafer covered by a monolayer of…

On the impedance response of a passive electrode : what is the influence of the double layer capacitance

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

Determination of the effective capacitance of passive films remains a difficult challenge and mostly relies on the assumption the contribution of the double layer can be neglected. Such an approximation is easy to verify a posteriori when data analysis is performed assuming that each of the…
