Formation of Ag Nanoparticles on β‑Ag2WO4 through Electron Beam Irradiation: A Synergetic Computational and Experimental Study
Alvarez Roca, Roman; Gouveia, Amanda; Lemos, Pablo S.; Gracia, Lourdes; Andres, Juan; Longo, Elson American Chemical Society (2016)In the present work, a combined theoretical and experimental study was performed on the structure, optical properties, and growth of Ag nanoparticles in metastable β- Ag2WO4 microcrystals. This material was synthesized ... -
Structural and electronic analysis of the atomic scale nucleation of Ag on α-Ag2WO4 induced by electron irradiation
Andres, Juan; Gracia, Lourdes; González Navarrete, Patricio; Longo, V. M.; Avansi, Waldir; Volanti, Diogo P.; Ferrer, Mateus M.; Lemos, Pablo S.; La Porta, Felipe A.; Hernandes, Antônio C.; Longo, Elson Nature Publishing Group (2014-06)In this work, we utilise a combination of theory, computation and experiments to understand the early events related to the nucleation of Ag filaments on α-Ag2WO4 crystals, which is driven by an accelerated electron beam ... -
Uncovering the metastable γ-Ag2WO4 phase: a joint experimental and theoretical study
Alvarez Roca, Roman; Lemos, Pablo S.; Gracia, Lourdes; Andres, Juan; Longo, Elson Royal Society of Chemistry (2017)The synthesis of metastable solid phases is a pivotal starting point for innovative materials research. Here, we report the synthesis by means of a precipitation method of the metastable cubic γ-Ag2WO4 phase under ambient ...
