    • openAccess   Anomalous oriented attachment growth behavior on SnO2 nanocrystals 

      Stroppa, Daniel G.; Montoro, Luciano A.; Beltran, Armando; Conti, Tiago G.; Da Silva, Rafael O.; Andres, Juan; Leite, Edson R.; Ramírez, Antonio J. Royal Society of Chemistry (2011)
      This work reports a detailed characterization of an anomalous oriented attachment behaviour for SnO2 nanocrystals. Our results evidenced an anisotropic growth for two identical 〈110〉 directions, which are equivalent according ...

    • openAccess   Microwave-hydrothermal synthesis of single-crystalline Co3O4 spinel nanocubes 

      Mulinari, Tatiana A.; La Porta, Felipe A.; Andres, Juan; Cilense, Mário; Varela, José A.; Longo, Elson The Royal Society of Chemistry (2013-07-29)
      An efficient microwave-hydrothermal (MAH) method has been developed for the synthesis of highly crystalline Co3O4 spinel nanocubes via beta-Co(OH)(2) without any surfactant assistance. The structure and surface chemical ...

    • openAccess   Piezoelectric Control of the Exciton Wave Function in Colloidal CdSe/CdS Nanocrystals 

      Segarra, Carlos; Climente, Juan I.; Polovitsyn, Anatolii; Rajadell Viciano, Fernando; Moreels, Iwan; Planelles, Josep American Chemical Society (2016-05-25)
      Using multiband k·p calculations, we show that strain-engineered piezoelectricity is a powerful tool to modulate the electron−hole spatial separation in a wide class of wurtzite CdSe/CdS nanocrystals. The inherent ...
