Effect of water on cobalt speciation during solid-state synthesis of Co2+/ZSM5 catalysts: quantitative study by TPR and XAS

Eric Marceau, Michel Che, Françoise Villain, Younès Ben Taarit

The effect of water on cobalt speciation in the synthesis of Co2+/ZSM5 catalysts is quantitatively studied by the combined use of macroscopic and local characterization techniques, TPR and X-ray absorption spectroscopies, respectively. The addition of a small quantity of water to cobalt acetate and…

Relantionship between the feedstock powders reactivity and the Electrochemical properties of 316L Stainless steel obtained by laser powder bed fusion

Alexis Fouchereau, Beatriz Puga, Hicham Maskrot, Fernando Lomello, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

3D printing by Laser-Powder Bed Fusion (L-PBF) is an innovative process using a high energy density laser to melt the raw material into a powder form. Previous studies have shown that the powder properties are crucial for the density, quality and microstructure of the materials produced [1, 2] but…

Application of Arrhenius law to DP and zero-span tensile strength measurements taken on iron gall ink impregnated papers: relevance of artificial ageing protocols

Véronique Rouchon, Oulfa Belhadj, Maroussia Duranton, Alice Gimat, Pascale Massiani

Iron gall inks (IGI) were largely used for writing until the nineteenth century. Under certain circumstances, they provoke a substantial degradation of their cellulosic support.It was shown in a previous works thatc ombination of oxygen and iron largely impacts cellulose chain breaking occurring in…

Gensdarmes, G. Dinescu, T. Acsente, Chiara Uboldi, Thierry Orsière, Veronique Malard, B. Rousseau, G. Dine, Ph. Delaporte, C Grisolia

During ITER operation, it is expected that the large panel of plasma-wall interactions triggers the production of dust particles from the tungsten and beryllium first wall. These particles can be loaded with tritium (T) used as a fuel for the fusion reaction; T inventory is of prime importance for…
