Influence of the temperature on the reduction mechanism of concentrated nitric acid on a silicon-enriched austenitic stainless steel

I. Bahtit, N. Gruet, B. Puga, X.R. Nóvoa, Cyril Thomas, V. Vivier

Corrosion of silicon-enriched stainless steel in nitric acid strongly depends on the temperature of the electrolyte. Therefore, the reduction reaction of nitric acid on this material was investigated from 40 to 107 °C. For the first time, the autocatalytic reduction mechanism of nitric acid…

Surface immobilization mechanisms of cobalt ions on hydroxyapatite catalyst supports

Corentin Reynaud, Cyril Thomas, Dalil Brouri, Yannick Millot, Antoine Miche, Guylène Costentin

Cobalt deposition in an excess of solution was used to design Co-modified hydroxyapatite materials with various Co loadings and controlled dispersion. It is rationalized how the properties of hydroxyapatite supports (more or less stoichiometric compositions, nanorod or platelet morphologies and…

Mechanism of RuO2 Crystallization in Borosilicate Glass: An Original in Situ ESEM Approach

Hassiba Boucetta, Renaud Podor, Lorenzo Stievano, Johann Ravaux, Xavier Carrier, Sandra Casale, S. Gossé, Amélie Monteiro, Sophie Schuller

Ruthenium, a fission product arising from the reprocessing of spent uranium oxide (UOX) fuel, crystallizes in the form of acicular RuO2 particles in high-level waste containment glass matrices. These particles are responsible for significant modifications in the physicochemical behavior of the…

The Influence of TiO2 Nanoparticles Morphologies on the Performance of Lithium-Ion Batteries

Wenpo Luo, Juliette Blanchard, Yanpeng Xue, Abdelhafed Taleb

Anode materials based on the TiO2 nanoparticles of different morphologies were prepared using the hydrothermal method and characterized by various techniques, such as X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and N2 absorption. The TiO2 nanoparticles prepared…

Inelastic light scattering by long narrow gold nanocrystals: when size, shape, crystallinity and assembly matter

Hervé Portalès, Nicolas Goubet, Sandra Casale, Xiang Zhen Xu, Mostapha Ariane, Alain Mermet, Jeremie Margueritat, Lucien Saviot

We report the synthesis of long narrow gold nanocrystals and the study of their vibrational dynamics using inelastic light scattering measurements. Rich experimental spectra are obtained for monodomain gold nanorods and pentagonal twinned bipyramids. Their assignment involves diameter-dependent non…

Transition-Metal-Free Catalysts for the Sustainable Epoxidation of Alkenes: From Discovery to Optimisation by Means of High Throughput Experimentation

Warunee Lueangchaichaweng, Inge Geukens, Annelies Peeters, Benjamin Jarry, Franck Launay, Jean-Luc Bonardet, Pierre A. Jacobs, Paolo P. Pescarmona

Abstract: Transition-metal-free oxides were studied as heterogeneous catalysts for the sustainable epoxidation of alkenes with aqueous H2O2 by means of high throughput experimentation (HTE) techniques. A full-factorial HTE approach was applied in the various stages of the development of the…
