Autor: Yannick Le Cozler, Elodie Brachet, Laurianne Bourguignon, Laurent Delattre, Thibaut Luginbuhl, Philippe Faverdin
Publikováno v: Sensors, Vol 22, Iss 12, p 4635 (2022)
The choice of rearing strategy for dairy cows can have an effect on production yield, at least during the first lactation. For this reason, it is important to closely monitor the growth and development of young heifers. Unfortunately, current methods

Hydrogen solubility, diffusivity and trapping in a tempered Fe–C–Cr martensitic steel under various mechanical stress states
Autor: F. Thebault, Laurent Delattre, Xavier Feaugas, Herve Marchebois, Jordi Creus, S. Frappart
Publikováno v: Materials Science and Engineering: A. 534:384-393
Electrochemical permeation test under stress conditions was carried out to determine the consequences of lattice distortion and defects on hydrogen solubility, diffusivity and trapping in a quenched and tempered martensitic steel. We focused our atte

A specific dependency of elastic tensile stress on the hydrogen solubility is identified for martensitic steels. The lattice hydrogen concentration under applied stress may be underestimated when predicted by a classical law which associates hydrosta

17O Solution NMR Characterization of the Preparation of Sol−Gel Derived SiO2/TiO2 and SiO2/ZrO2 Glasses
Autor: Florence Babonneau, Laurent Delattre
Publikováno v: Chemistry of Materials. 9:2385-2394
17O nuclear magnetic resonance was used to investigate the classical two-step procedure for the preparation of sol−gel derived SiO2−TiO2 or SiO2−ZrO2 glasses. The formation of significant amount of Si−O−M bonds (M = Ti, Zr), resulting from

Design of homogeneous hybrid materials through a careful control of the synthetic procedure
Autor: Florence Babonneau, Laurent Delattre, Magalie Roy
Publikováno v: Journal of Sol-Gel Science and Technology. 8:567-570
Sols for the synthesis of hybrid organic-inorganic materials have been prepared by mixing zirconium n-propoxide and methacryloxypropyltrimethoxysilane (MPS). The synthesis was done in two steps: a 15 minute hydrolysis of a MPS : H2O : EtOH 1 : 1 : 2

Characterization of the hydrolysis and polymerization processes of methacryloxypropyltrimethoxysilane
Autor: Laurent Delattre, Carole Dupuy, Florence Babonneau
Publikováno v: Journal of Sol-Gel Science and Technology. 2:185-188
The sol-gel synthesis of hybrid methacrylate-silica materials using methacryloxypropyltrimethoxysilane (MPS) as precursor, has been analyzed using 1H and 29Si liquid NMR as well as 29Si and 13C MAS-NMR. Under the present experimental conditions (H2O/
