Characterization of nanostructured material images using fractal descriptors
(ElsevierAmsterdam, 2013-04)
This work presents a methodology to the morphology analysis and characterization of nanostructured material images acquired from FEG-SEM (Field Emission Gun-Scanning Electron Microscopy) technique. The metrics were extracted ...
Thermal, morphostructural and spectrometric characterization of an antibacterial kaolinite-based filter modified with silver for water treatment
(2020-01-01)
The aim of this work is to synthesize and characterize a new structured silver–clay dried, calcined or sintered at different temperatures composite by TG–DTA analysis, FTIR spectrometry analysis, XRD and Rietveld refinement, ...
El efecto espejo en el MEB y su uso práctico en el estudio de propiedades dieléctricas de materiales: el diente humano
(Universidad Michoacana de San Nicolás de Hidalgo, 2017-03)
The mirror effect is produced with electrons in the Scanning Electron Microscope (SEM) and its origin is in the accumulation of electrostatic charge in non-conducting samples. The accumulation of charge on the area where ...
Transporte eletrônico em filmes ultrafinos nanoestruturados : o sistema SNO2:SB
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2015-12-14)
This thesis describes a study of the electronic charge transport properties in antimony-doped tin oxide (ATO) ultrathin films, prepared by two different methods: by colloidal deposition process (CDP) and by pulsed electron ...
Métodos para caracterização de meios filtrantes contendo nanofibras
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-05-02)
It is necessary knowing the characteristics of the filter media and how they influence the
filtration process to improve the filter media. With this, the aim of this study was to
characterize the filter media containing ...
Glass ionomer cement modified by resin with incorporation of nanohydroxyapatite: In vitro evaluation of physical-biological properties
(2020-07-01)
Resin-modified glass ionomer cement (RMGIC) has important properties. However, like other restorative materials, it has limitations such as decreased biocompatibility. The incorporation of nanoparticles (NP) in the RMGIC ...
Effects of gamma radiation on the thermoanalytical, structural and pasting properties of black rice (Oryza sativa L.) flour
(Springer, 2018-07-01)
The effects of different doses of gamma radiation on the thermoanalytical, structural and pasting properties of black rice (Oryza sativa L.) flour were studied using thermogravimetry and derivative thermogravimetry (TG-DTG), ...
Desenvolvimento de materiais híbridos baseados em nanopartículas de sílica densa decoradas com grupos carboxilatos e complexos luminescentes de európio
(Universidade Estadual Paulista (Unesp), 2019-03-01)
Biomarcadores luminescentes a base de íons lantanídeos tivalentes (Ln3+) vêm sendo aplicados como sondas luminescentes em imageamento celular e marcação biológica devido às suas excelentes propriedades óticas. Sua obtenção ...
Síntese e estudo das propriedades fotoluminescentes dos pós de CaTiO3 decorados com α-Ag2WO4
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-02-24)
The CaTiO3 (CT) and α-
Ag2WO4 (AW) are known to have photoluminescent properties, which is favored by
the existence of a structural disorder. The combination of these two materials was
observed through decoration of ...
One-step controllable synthesis of three-dimensional WO3 hierarchical architectures with different morphologies decorated with silver nanoparticles: Enhancing the photocatalytic activity
(2020-01-01)
Hierarchical architecture self-assembled three-dimensional WO3 and WO3·Ag with high uniformity have been successfully obtained using peroxopolytungstic acid as precursor and silver in a morphological engineering approach ...
