• openAccess   A DFT Study of Structural and Electronic Properties of ZnS Polymorphs and its Pressure-Induced Phase Transitions 

      La Porta, Felipe A.; Gracia, Lourdes; Andres, Juan; Sambrano, Julio; Varela, José A.; Longo, Elson John Wiley & Sons (2014)
      A systematic first-principles investigation, by using the density functional formalism with the nonlocal B3LYP approximation including a long-range dispersion correction, has been performed to calculate the structural and ...
    • openAccess   Charge control in laterally coupled double quantum dots 

      Muñoz Matutano, G.; Royo Valls, Miguel; Climente, Juan I.; Canet Ferrer, J.; Fuster, D.; Alonso-Jordá, Pedro; Fernández Martínez, Iván; Martínez-Pastor, Juan P.; González Diez, Yolanda; González Sotos, Luisa; Briones, Fernando; Alen Millán, B. American Physical Society (2011-07-27)
      We investigate the electronic and optical properties of InAs double quantum dots grown on GaAs (001) and laterally aligned along the [110] crystal direction. The emission spectrum has been investigated as a function of a ...
    • openAccess   Electronic structure and magnetic properties of FeWO4 nanocrystals synthesized by the microwave-hydrothermal method 

      Cavalcante, Laécio Santos; Morilla-Santos, C.; Lisboa Filho, Paulo N.; Beltran, Armando; Andres, Juan; Gracia, Lourdes; Longo, Elson; Almeida, M.A.P. Elsevier (2012)
      This communication reports that FeWO4 nanocrystals were successfully synthesized by the microwave-hydrothermal method at 443 K for 1 h. The structure and shape of these nanocrystals were characterized by X-ray diffraction, ...
    • openAccess   Experimental and theoretical approach of nanocrystalline TiO2 with antifungal activity 

      Longo, V. M.; Picon, Francini C.; Zamperini, Camila; Albuquerque, Anderson R.; Sambrano, Julio; Vergani, Carlos; Machado Maciel, Ana Lúcia; Andres, Juan; Hernandes, Antônio C.; Varela, José A.; Longo, Elson Elsevier (2013-07-09)
      Using a solvothermal method for this research we synthesized nanocrystalline titanium dioxide (nc-TiO2) anatase particles with a mean diameter of 5.4 nm and evaluated their potential antifungal effect against planktonic ...
    • closedAccess   Toward an Understanding of the Growth of Ag Filaments on a-.Ag2WO4 and Their Photoluminescent Properties: A Combined Experimental and Theoretical Study 

      Longo, Elson; Volanti, Diogo P.; Longo, V. M.; Gracia, Lourdes; Nogueira, Içamira C.; Almeida, M.A.P.; Pinheiro, Antonio N.; Ferrer, Mateus M.; Cavalcante, Laécio Santos; Andres, Juan American Chemical Society (2013-12)
      A combined experimental and theoretical study was conducted on the structure and electronic properties of α-Ag2WO4 to clarify the nucleation and growth processes of Ag filaments on α-Ag2WO4 crystals induced by electron ...
