Fracture resistance of textured polycrystalline Zr: A simulation study
(Elsevier, 2019-05)
We report the results of large-scale molecular dynamics atomistic simulations of crack propagation in of α-Zirconium. The samples studied are polycrystalline columnar grains of 11–38 nm average diameter, and different ...
Effects of synthesis conditions on the nanostructre of CexZr1-xO2 mesoporous ceramics.
(Quebec, 2013-08-12)
CexZr1-xO2 (0.5 ≤ x ≤ 0.9) were synthesized with Zr and Ce chloride precursors, using the triblock
copolymer Pluronic P123 and HCl (2 mol/L). The pH adjustment was performed in two ways: synthesis
A used 11.4 mL of a ...
Crecimiento y caracterización de películas delgadas de nitruro de titanio circonio (Ti,Zr)N
(2009)
En el presente trabajo se presentan los detalles experimentales de la implementación metodológica para la producción de películas delgadas de nitruro de titanio circonio (Ti,Zr)N por medio de la técnica deposición física ...
Ce-Zr-Sm ternary oxides synthesized via a template free urea-hydrothermal method
(Elsevier, 2022-05-24)
Nano-crystalline Ce0.9Zr0.1-xSmxO2-δ (0 ≤ x ≤ 0.10) mixed oxides were synthesized for the first time by a urea-hydrothermal method without the use of template or structure directing agents. The use of a high molar ratio ...
Aplicação de nanopartículas de ZrO2 para a melhoria da qualidade do cimento
(Universidade Estadual Paulista (Unesp), 2021-07-27)
A indústria de cimento enfrenta desafios na conservação de materiais e recursos energéticos. A intercalação de aditivos na nanoestrutura C-S-H contribui para o preenchimento dos poros da pasta de cimento, tornando-a mais ...
Caracterización estructural de la transición de fase del intermetálico Al2Cu durante la molienda mecánica de alta energía
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-02)
The present research is related to the high energy mechanical milling (MM) process of the inter alloy Al 2 Cu at different times. This process is characterized by an out-of-equilibrium processing, which consists in the ...
