In situ Formation of Metal Nanoparticles through Electron Beam Irradiation: Modeling Real Materials from First-Principles Calculations
Andres, Juan; Longo, Elson; Gouveia, Amanda; Costa, João Paulo C.; Gracia, Lourdes; Oliveira, M. C. OMICS International (2018-06)Advances in electron-matter studies, based on the irradiation of the electron beam in the transmission electron microscopy or field emission-scanning electron microscope on materials represents a preferred external physical ... -
In Situ Growth of Bi Nanoparticles on NaBiO3, delta-, and beta-Bi2O3 Surfaces: Electron Irradiation and Theoretical Insights
Assis, Marcelo de; Carvalho de Oliveira, Marisa; Machado, Thales Rafael; Guerra Macedo, Nadia; Costa, João Paulo C.; Gracia, Lourdes; Andres, Juan; Longo, Elson American Chemical Society (2019-02-04)Herein, we present a combined experimental and theoretical study of the in situ growth of Bi nanoparticles on NaBiO3, δ-, and β-Bi2O3 surfaces mediated by the electron beam of a high-resolution transmission electron ... -
α- and β-AgVO3 polymorphs as photoluminescent materials: An example of temperature-driven synthesis
Oliveira, Regiane; Teixeira, Mayara Mondego; Costa, João Paulo C.; Penha, Maya; Francisco, Eric Mark; da Silva, Jussara Soares; Li, Maximo Siu; Longo, Elson; Gracia, Lourdes; Andres, Juan Elsevier (2018-04-15)Controlling the synthesis of a given polymorph of an inorganic material is a further step in the design of property and function. In this letter, we report for the first time a simple procedure to effectively control the ...
