Low temperature synthesis of hexagonal Bi2Te3 nanoplates using an open reactor and its effect on their physicochemical properties
Published 2024“…A vibrational mode at 120 cm−1 due to the breaking of the symmetry of the Bi2Te3 crystal along the C axis was observed by Raman spectroscopy. XPS results showed that despite the strong reactivity of Te2− ions with ambient oxygen, the crystallization of Bi2Te3 hexagonal nanoplates is feasible without controlled vapor pressure and at a lower temperature than reported in other works. …”

Study of structural properties of BiOI on ZnO thin films and ZnO nanorods
Published 2019“…The scanning electron microscopy analysis showed that BiOI grew on the ZnO-NR surfaces in nanoplatelet shape with an order of magnitude smaller in size, with respect to the platelets observed in BiOI thin films. Analysis by X-ray diffraction exhibited the hexagonal P63mc phase of ZnO and the tetragonal P4nmm crystal phase of BiOI. …”

Myocardial perfusion in patients with ST depression during the recovery phase of treadmill stress tests
Published 2009“…Fixed only perfusion abnormalities were found in 3 patients (6%), seven (14%) had fixed and reversible perfusion defects and 20 (40%) showed ischemia only. Ischemia was observed in the anterior wall in 10 patients, inferior wall in 12, lateral wall in 5, apex in 8 and septum in 1 patient. …”

FePt icosahedra with magnetic cores and catalytic shells
Published 2009“…Computational studies and energy-filtered transmission electron microscopy analyses suggest that a Pt-enriched surface layer is energetically favored and that site-specific vacancies are formed at the edges of facettes, which was experimentally observed. The presence of the Pt-enriched shell around an Fe/Pt core explains the environmental stability of the magnetic icosahedra and strongly reduces the exchange coupling between neighboring particles, thereby possibly providing the highest packing density for future magnetic storage media based on FePt nanoparticles.…”

On the structure and properties of silver nanoparticles
Published 2008“…We also found that both the size and shape of the nanoparticles determine the shift of the UV-visible absorption spectrum. Finally, we observed the formation of atomic islands above the faces of the Ag tetrahedral NPs, in agreement with the results obtained from the MD simulations.…”
