Topological derivative-based optimization of micro-structures considering different multi-scale models
(Tech Science Press, 2010)
A recently proposed algorithm for micro-structural optimization, based on the concept of topological derivative and a level-set domain representation, is applied to the synthesis of elastic and heat conducting bi-material ...
Fast and ejficient microwave-assisted synthesis of CaTiO3
(2017-06-01)
The traditional methods to synthesize nanocrystalline materials are energy-intensive and time-consuming. This paper describes a fast and simple route to synthesize CaTiO3, which requires just 30 s of processing in the HTMW ...
Key parameters to improve zeolites hierarchization in direct synthesis
(Indian Academy of Sciences, 2020-10-29)
In this study, we propose the generation of micro/mesoporous zeolites with ZSM-11 structure by hydrothermal treatment using tetrabutylammonium hydroxide (TBAOH) as micropore structure directing agent and cetyltrimethylammonium ...
Structural, optical and vibrational properties of ZnO:M (M=Al3+ and Sr2+) nano and micropowders grown by hydrothermal synthesis
(Elsevier Science SA, 2019-06)
Powders of ZnO and ZnO:M (M = Al3+ and Sr2+) with 1 and 4% of M nominal content were synthetized by a hydrothermal method in a diethanolamine (DEA) medium. The samples were studied by scanning electron microscopy (SEM), ...
ZnO nanoparticle/poly(vinyl alcohol) nanocomposites via 2 microwave-assisted sol−gel synthesis for structural materials, UV 3 shielding, and antimicrobial activity
(American Chemical Society, 2021-06-09)
Polymer nanocomposites based on poly(vinyl alcohol) (PVA) and ZnO hold a privileged position in the development of organic/inorganic hybrid multifunctional materials for applications ranging from food packing to biotechnological ...
Freezing Distortions and Photoluminescence Property in PbMoO4 Micro Octahedrons: An Experimental and Theoretical Study
(2013)
In this paper, we report a detailed structural and electronic characterization of PbMoO4 crystals by using a conventional hydrothermal (CH) method. The samples were characterized by X-ray diffraction (XRD), Fourier transform ...
Estudo da obtenção de nitreto de boro hexagonal por rotas de síntese assistidas por micro-ondas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-02-05)
Boron nitride (h-BN) is an attractive ceramic material that combines
excellent thermal, electrical and chemical properties. The combination of these
properties makes h-BN useful in the manufacturing of lubricants, ...
Metastability effects on the photoluminescence of ZnO nano-micro structures grown at low temperature and influence of the precursors on their morphology and structure
(IOP Publishing, 2018-09)
Nanocrystalline ZnO films were grown on silicon substrate by hydrothermal synthesis at 125 °C, using diethanolamine as stabilizer. A powder containing ZnO spheres, with diameters between 100 to 200 nm and formed by aggregation ...
