    • openAccess   A novel ozone gas sensor based on one-dimensional (1D) α-Ag2WO4 nanostructures 

      Da Silva, Luis F.; Catto, Ariadne C.; Avansi, Waldir; Cavalcante, Laécio Santos; Andres, Juan; Aguir, Khalifa; Mastelaro, Valmor Roberto; Longo, Elson Royal Society of Chemistry (2014-01)
      This paper reports on a new ozone gas sensor based on α-Ag2WO4 nanorod-like structures. Electrical resistance measurements proved the efficiency of α-Ag2WO4 nanorods, which rendered good sensitivity even for a low ozone ...

    • openAccess   Acetone gas sensor based on α-Ag2WO4 nanorods obtained via a microwaveassisted hydrothermal route 

      Da Silva, Luis F.; Catto, Ariadne C.; Avansi, Waldir; Cavalcante, Laécio Santos; Mastelaro, Valmor Roberto; Andres, Juan; Aguir, Khalifa; Longo, Elson Elsevier (2016)
      This manuscript addresses the synthesis of one-dimensional (1D) α-Ag2WO4 nanorod-like structures via a microwave-assisted hydrothermal method to be used as an acetone gas sensor. The nanorods showed excellent gas-sensing ...

    • closedAccess   Improving the ozone gas-sensing properties of CuWO4 nanoparticles 

      Catto, Ariadne C.; Fiorido, Tomas; Souza, Érica L.S.; Avansi, Waldir; Andres, Juan; Aguir, Khalifa; Longo, Elson; Cavalcante, Laécio Santos; Da Silva, Luis F. Elsevier (2018-06)
      This paper consists of an experimental investigation on the effects of annealing temperature on the structural, surface and ozone gas-sensing properties of CuWO4 nanoparticles prepared via a sonochemical route. X-ray ...

    • openAccess   The role of counter-ions in crystal morphology, surface structure and photocatalytic activity of ZnO crystals grown onto a substrate 

      Catto, Ariadne C.; Ferrer, Mateus M.; Lopes, Osmando; Mastelaro, Valmor Roberto; Andres, Juan; Da Silva, Luis F.; Longo, Elson; Avansi, Waldir Elsevier (2020-11-01)
      In this contribution, we present an experimental and theoretical investigation of the role of counter-ions in the crystal morphology, surface structure, and photocatalytic activity of hierarchical ZnO nanostructures. The ...

    • openAccess   Unveiling the efficiency of microwave-assisted hydrothermal treatment for the preparation of SrTiO3 mesocrystals 

      Da Silva, Luis F.; Catto, Ariadne C.; Avansi, Waldir; Mesquita, Alexandre; Maia, Lauro; Lopes, Osmando; Li, Máximo Siu; Moreira, Mario Lucio; Longo, Elson; Andres, Juan; Mastelaro, Valmor Roberto Royal Society of Chemistry (2019-09-16)
      Material processing has become essential for the proper control, tuning and consequent application of the properties of micro/nanoparticles. In this case, we report herein the capability of the microwaveassisted hydrothermal ...
