Electronic structure, growth mechanism and photoluminescence of CaWO4 crystals
(Royal Soc Chemistry, 2012-01-01)
In this paper, aggregated CaWO4 micro-and nanocrystals were synthesized by the co-precipitation method and processed under microwave-assisted hydrothermal/solvothermal conditions (160 degrees C for 30 min). According to ...
Optimal aerodynamic design of multi-flapping wing vehicles with morphing capabilities
(2021-01-01)
Some groups of birds have the ability to save energy during flight by arranging themselves in V-formation. This formation enables an increase in the overall efficiency of the group because the wake vortices shed by each ...
PROPIEDADES MECÁNICAS DE ACEROS BORURADOS AISI 1018 EVALUADAS POR INDENTACIÓN A ESCALA MICRO Y NANOMÉTRICA
(2011-10-13)
The present study evaluated the indentation size effect on the Fe2B layer at micrometric
scale, using the Vickers technique and on the Fe2B/substrate interface, at nanometric
scale by mean of the Berkovich nanoindentation ...
Density functional theory-based cluster expansion to simulate thermal annealing in FeCrW alloys
(Taylor & Francis Ltd, 2017-02)
In this work, we develop a rigid lattice cluster expansion as an ultimate goal to track the micro-structural evolution of Eurofer steel under neutron irradiation. The fact that all (defect) structures are mapped upon a ...
Influência dos íons Cu2+ nas propriedades ópticas dos pós de (Ca1-x Cux)TiO3 preparados por métodos químicos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2012-10-29)
The influence of Cu2+ doping as well as the preparation methods on the structural, morphological and optical properties of (Ca1-xCux)TiO3 powders with (x= 0; 0,01; 0,02; 0,04 and 0,10) of Cu2+ were studied in this work. ...
Micro-maquinado multi-ejes CNC aplicado a implantes dentales en aleación de Titanio Ti-6Al-4V
(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Materiales y ProcesosDepartamento de Ingeniería Mecánica y MecatrónicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
El micro-maquinado mecánico es una operación de micro-fabricación destacada en el área del corte de metales, especialmente cuando se aplica a materiales de ingeniería como las aleaciones de titanio. En la actualidad, el ...
Structural refinement and photoluminescence properties of cube-like (Ca 1-xCu x)TiO 3 crystals synthesized by the microwave-hydrothermal method
(2012-08-20)
In this work, (Ca 1-xCu x)TiO 3 crystals with (x = 0, 0.01 and 0.02), labeled as CTO, CCTO1 and CCTO2, were synthesized by the microwave-hydrothermal method at 140°C for 32 min. XRD patterns (Fig. 1), Rietveld refinement ...
