Electron count and electronic structure of bare icosahedral Au32 and Au33 ionic nanoclusters and ligated derivatives. Stable models with intermediate superatomic shell fillings
(NLM (Medline), 2020-09-23)
DFT calculations were carried out on bare Au32 and Au33 nanoclusters with various charges, in order to analyze their stability with respect to different cluster electron numbers. Results indicate that in addition to the ...
Melamine -formaldehyde microcapsules: micro - and nanostructural characterization with electron microscopy
(Cambridge University Press, 2016-11)
A systematic study has been carried out to compare the surface morphology, shell thickness, mechanical properties and binding behavior of melamine formaldehyde icrocapsules of 5 to 30 µm diameter size with various amounts ...
Combined methods to detect pollution effects on shell shape and structure in Neogastropods
(Elsevier Science, 2011-03)
Tributyltin (TBT) has been widely used as antifouling in marine environments, producing imposex in gastropod females (i.e. neoformation of a vas deferens and/orapenis) and shell malformation sinbivalves. However, effects ...
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 ...
AuPd/C core-shell and alloy nanoparticles with enhanced catalytic activity toward the electro-oxidation of ethanol in alkaline media
(Elsevier B.V., 2019-08-15)
Carbon-supported Pd, Au@Pd core-shell and Au1-xPdx-alloyed nanoparticles were prepared by a chemical reduction method and characterized by different experimental techniques, including X-ray powder diffraction, transmission ...
Morphological and compositional characteristics of bimetallic core@shell nanoparticles revealed by MEIS
(Elsevier Science, 2015-03)
In this paper we report the application of a suitable methodology to study the morphology, structure and composition of core@shell nanoparticles (NPs) systems with polydispersity in the shell thickness, with subnanometer ...
Simple correlated wavefunctions for the K-shell electrons of neutral atoms
(IOP Publishing, 2005-12)
Simple correlated wavefunctions considering two K-shell active electrons
of neutral atoms from He to Xe are presented in this paper, describing a
variational method subject to a local Hartree potential representing the ...
Hylleraas-like functions with the correct cusp conditions: K-shell electrons for the neutral atoms
(Elsevier Science, 2007-12)
We present simple correlated wavefunctions for the two K-shell electrons of neutral atoms. A variational method was chosen to calculate the mean energy of the ground state, in which the electrons are subject to a local ...
