Magnetic Iron Oxide Nanoparticles in 10−40 nm Range: Composition in Terms of Magnetite/Maghemite Ratio and Effect on the Magnetic Properties
Jaime Santoyo Salazar,Lucas Pérez,Lai Truong Phuoc,Dris Ihiawakrim,Manuel Vázquez,Jean-Marc Greneche,Sylvie Begin-Colin,Geneviève Pourroy +7 more
TL;DR: In this paper, magnetic iron oxide nanoparticles in the 10−40 nm size range and with a reduced distribution in size were synthesized under argon by using ammonium bases R4NOH (R = CH3, C2H5, C3H7) and a hydrothermal treatment.
Journal ArticleDOI
Morphological and Structural Evolution of Co3O4 Nanoparticles Revealed by in Situ Electrochemical Transmission Electron Microscopy during Electrocatalytic Water Oxidation.
Nathaly Ortiz Peña,Dris Ihiawakrim,Madeleine Han,Benedikt Lassalle-Kaiser,Sophie Carenco,Clément Sanchez,Christel Laberty-Robert,David Portehault,Ovidiu Ersen +8 more
TL;DR: This study demonstrates that it is possible to rely on in situ electrochemical TEM to reveal processes in electrocatalysts while preserving a good correlation with ex situ regular electrochemistry.
Journal ArticleDOI
3D analysis of the morphology and spatial distribution of nitrogen in nitrogen-doped carbon nanotubes by energy-filtered transmission electron microscopy tomography.
Ileana Florea,Ovidiu Ersen,Raul Arenal,Raul Arenal,Dris Ihiawakrim,Cédric Messaoudi,Kambiz Chizari,Izabela Janowska,Cuong Pham-Huu +8 more
TL;DR: The application of the energy-filtered transmission electron microscopy in the tomographic mode to determine the precise 3D distribution of nitrogen within nitrogen-doped carbon nanotubes (N-CNTs) allowed the observation of an unexpected change in morphology along the tube axis.
Journal ArticleDOI
Three-dimensional tomographic analyses of CeO2 nanoparticles
Ileana Florea,Cédric Feral-Martin,Jérôme Majimel,Dris Ihiawakrim,Charles Hirlimann,Ovidiu Ersen +5 more
TL;DR: In this paper, a detailed morphological and structural analysis of CeO2 nanoparticles has been performed using electron tomography in scanning transmission mode in high angle annular dark field.
Journal ArticleDOI
