Proposta de um protocolo para o processamento de requisitos do cliente em empreendimentos habitacionais de interesse social
(2011) [Journal article]Muitos estudos têm apontado a importância do gerenciamento dos requisitos do cliente e as dificuldades para sua implementação na indústria da construção devido à natureza complexa de seus processos. Na habitação de interesse ... -
Adsorption properties of magnetic CoFe2O4@SiO2 decorated with P4VP applied to bisphenol A
(2023) [Journal article]In this study, the preparation and adsorption properties of cobalt ferrite core-shell nanoparticles coated with silica and decorated with poly(4-vinylpyridine) (CoFe2O4@SiO2-P4VP) applied to bisphenol A (BPA) adsorption ... -
Tunneling spectroscopy of few-monolayer NbSe2 in high magnetic fields : triplet superconductivity and Ising protection
(2022) [Journal article]In conventional Bardeen-Cooper-Schrieffer superconductors, Cooper pairs of electrons of opposite spin (i.e., singlet structure) form the ground state. Equal-spin triplet pairs (ESTPs), as in superfluid 3 He, are of great ... -
Tungsten oxide supported on copper ferrite : a novel magnetic acid heterogeneous catalyst for biodiesel production from low quality feedstock
(2022) [Journal article]This study aims to synthesize a WO3/CuFe2O4 catalyst through a wet impregnation method and use it as a new magnetic acid catalyst in the transesterification process of waste cooking oil (WCO). The results of the characterization ... -
Um estudo sobre a influência de um programa de mentoria na motivação para a persistência de licenciandos em física durante o ensino remoto emergencial
(2023) [Journal article]Dificuldades de adaptação ao contexto universitário costumam influenciar a motivação para persistir dos calouros. Um programa de mentoria pode favorecer a persistência ao amenizar as dificuldades na transição para a ... -
Cultura livre na educação : uma revisão da literatura sobre o uso de Tecnologias Livres, Ciência Aberta e Recursos Educacionais Abertos no ensino de Física e Engenharia
(2022) [Journal article]Com o objetivo de compreender a abordagem das pesquisas em ensino de Física e Engenharia em relação aos preceitos e ferramentas da Cultura Livre – especialmente em relação aos movimentos de Ciência Aberta, Recursos ... -
Catalog of magnetic white dwarfs with hydrogen dominated atmospheres
(2023) [Journal article]White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other ... -
Population and coherence dynamics in large conjugated porphyrin nanorings
(2022) [Journal article]In photosynthesis, nature exploits the distinctive electronic properties of chromophores arranged in supramolecular rings for efficient light harvesting. Among synthetic supramolecular cyclic structures, porphyrin nanorings ... -
Spatially resolved observations of outflows in the radio loud AGN of UGC 8782
(2023) [Journal article]We use optical integral field spectroscopy (IFU) to study the gas emission structure and kinematics in the inner 3.4 × 4.9 kpc2 region of the galaxy UGC 8782 (3C 293), host of a radio loud active galactic nucleus (AGN). ... -
The AGNIFS survey : spatially resolved observations of hot molecular and ionized outflows in nearby active galaxies
(2023) [Journal article]We present the hot molecular and warm ionized gas kinematics for 33 nearby (0.001 ≲ z ≲ 0.056) X-ray selected active galaxies using the H22.1218μ m and Br γ emission lines observed in the K band with the Gemini near-infrared ...
