Exploring the benefits of electron tomography to characterize the precise morphology of core-shell Au@Ag nanoparticles and its implications on their plasmonic properties
(Royal Society of Chemistry, 2014-08)
In the design and engineering of functional core–shell nanostructures, material characterization at small length scales remains one of the major challenges. Here we show how electron tomography in highangle annular dark-field ...
Highly anisotropic distribution of iron nanoparticles within MCM-41 Mesoporous Silica
(Pergamon-Elsevier Science Ltd, 2006-12)
Electron microscopy techniques are used to visualize the spatial distribution of iron nanoparticles inside a mesoporous MCM-41 molecular sieve. Direct observation of the iron oxide nanoparticles by STEM-HAADF imaging reveals ...
Effects of catalyst load in Pt and Pb-based catalysts using formic acid oxidation as a model
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we discuss the effects of catalyst load with respect to carbon powder for several Pt and Pb-based catalysts, using formic acid as a model molecule. The discussion is based on electrochemical tests, a complete ...
Iron oxide nanoparticles inside the MCM-41 channels: Study of the structural stability of the support
(Elsevier Science, 2005-09)
We report the synthesis of the MCM-41 mesoporous solid chosen as support of Fe nanoparticles, which yields a narrow distribution of oxide crystal sizes. MCM-41 was synthesized in two different ways, with and without pH ...
Scanning transmission electron microscopy methods for the analysis of nanoparticles

Analysis of electron beam damage of exfoliated MoS2 sheets and quantitative HAADF-STEM imaging
(Elsevier Science, 2014-06)
In this work we examined MoS2sheets by aberration-corrected scanning transmission electron micro-scopy (STEM) at three different energies: 80, 120 and 200 kV. Structural damage of the MoS2sheets hasbeen controlled at 80 ...
Elastic distortion determining conduction in BiFeO3phase boundaries
(Royal Society of Chemistry, 2020-07)
It is now well-established that boundaries separating tetragonal-like (T) and rhombohedral-like (R) phases in BiFeO3 thin films can show enhanced electrical conductivity. However, the origin of this conductivity remains ...
In situ growth of metal-organic framework HKUST-1 in an organic polymer as sorbent for nitrated and oxygenated polycyclic aromatic hydrocarbon in environmental water samples prior to quantitation by HPLC-UV
(Springer Wien, 2020-05)
An in situ preparation of metal-organic framework (HKUST-1) on the surface of an organic polymer is reported. The hybrid material was evaluated as sorbent for solid-phase extraction (SPE) of oxygenated and nitrated polycyclic ...
Ultra-small rhenium clusters supported on graphene
(Royal Society of Chemistry, 2015-03)
The adsorption of very small rhenium clusters (2-13 atoms) supported on graphene was studied by high-angle annular dark field-scanning transmission electron microscopy (HAADF-STEM). The atomic structure of the clusters was ...
