Formation and Growth of Au Nanoparticles inside Live Alfalfa Plants
Jorge L. Gardea-Torresdey,Jason G. Parsons,E. Gomez,Jose R. Peralta-Videa,Horacio Esteban Troiani,P Santiago,M. José Yacamán,M. José Yacamán +7 more
TL;DR: In this paper, the authors used live plants for the fabrication of nanoparticles and found that the Au nanoparticles are in a crystalline state and showed defects such as twins in the crystal structure and icosahedral nanoparticles were found.
Journal ArticleDOI
Micronized powders of a poorly water soluble drug produced by a spray-freezing into liquid-emulsion process.
True L. Rogers,True L. Rogers,Kirk Overhoff,Parag S. Shah,P Santiago,Miguel Jose Yacaman,Keith P. Johnston,Robert O. Williams +7 more
TL;DR: Large-scale SFL product batches were manufactured using lower solvent quantities and higher drug concentrations via emulsion formulations, thus demonstrating the usefulness of the SFL micronization technology in pharmaceutical development.
Journal ArticleDOI
Fullerenic structures derived from oil asphaltenes
G.A Camacho-Bragado,P Santiago,M Marin-Almazo,M Espinosa,E.T Romero,Juan Murgich,V Rodriguez Lugo,M Lozada-Cassou,Miguel Jose-Yacaman,Miguel Jose-Yacaman +9 more
TL;DR: In this article, the authors applied high resolution transmission electron microscopy (HREM) and energy dispersive spectrometry (EDS) in the study of asphaltenes.
Journal ArticleDOI
Diamond Polytypes in Mexican Crude Oil
P Santiago,G. Alejandra Camacho-Bragado,Margarita Marin-Almazo,Juan Murgich,Miguel Jose-Yacaman +4 more
TL;DR: The presence of C nanoparticles in the asphaltenes precipitated from a crude oil from the sureste Basin in Mexico is reported in this paper, where most of the near spherical nanoparticles were identified as the 3C cub...
Journal ArticleDOI
Growth and thermal annealing of Cu on HfO2
TL;DR: In this paper, the authors examined the interface between Cu and HfO2 synthesized using physical vapor deposition at 300 K with in situ low-energy ion scattering (LEIS), in situ X-ray photoelectron spectroscopy (XPS), and ex situ scanning transmission electron microscopy (STEM) data.
