Crescimento de filmes finos de NbN por magnetron sputtering reativo
(Universidade Federal de Santa Maria, 2013-02-18)
In the last decades, several applications of niobium nitride thin films has been proposed
or effectively implemented. In the cubic δ − NbN phase, the bulk material presents a Tc for
the superconducting transition near ...
Formação de texturas cristalográficas em filmes finos de NbN
(Universidade Federal de Santa Maria, 2017-12-20)
Niobium nitride (NbN) thin films can be hard and resistant not only to mechanical wear but
also to chemically aggressive atmospheres. Additionally, they can present a superconducting
transition in temperatures that are ...
Um modelo para a evolução de redes de proteínas contemplando a transferência horizontal de genes
(Universidade Federal de Santa Maria, 2022-03-31)
Around us we find several examples of complex systems, which are composed of a large
number of elements that interact with each other in very complex ways. These systems
range from the World Wide Web itself to energy ...
Oxidação de nanofios de InP: um estudo de primeiros princípios
(Universidade Federal de Santa Maria, 2012-12-17)
A study of InP nanowires with an oxide layer, as well as the initial steps of the oxidation process is pursued through first principles calculations and molecular dynamics simulations within the Density Functional Theory. ...
A hipótese de turbulência localmente isotrópica e a universalidade da constante de Kolmogorov
(Universidade Federal de Santa Maria, 2006-05-03)
According to the Kolmogorov's fully developed turbulence theory established in 1941, there is an equilibrium range in which phenomenological quantities associated to the turbulence flow are described by laws of universal ...
Estudo teórico de compostos de C6F5-corrol funcionalizados com hidrocarbonetos aromáticos para aplicações em terapia fotodinâmica
(Universidade Federal de Santa Maria, 2021-09-06)
The oxygen singlet generation by molecules in photodynamic therapy (PDT) requires an
electronic excitation by light absorption within a specific wavelength window, and a subsequent
intersystem crossing transition to a ...
Velocidade do som em matéria quente e densa de quarks
(Universidade Federal de Santa Maria, 2022-04-25)
In this work two different approaches to the regularization of thermal integrals in the NJL
(Nambu–Jona-Lasinio) SU(2) model are investigated from the phenomenological point of
view. Showing the usefullness of the speed ...
Medida da magnetização de filmes finos: desenvolvimento de um magnetômetro kerr
(Universidade Federal de Santa Maria, 2014-02-21)
The Kerr effect is the rotation of the plane of polarization of a light beam during
reflection on a magnetized sample. In this work we built an optical Kerr effect
magnetometer Longitudinal (L-MOKE) and measured the ...
Análise da origem da emissão e cinemática do gás na região central da galáxia NGC4546
(Universidade Federal de Santa Maria, 2020-03-11)
It is believed that most spheroidal galaxies host a Supermassive Black Hole (SMBH) at their centers and that, at some point, it becomes active, originating an Active Galaxy Nuclei (AGN). The formation and evolution of the ...
Cinemática bidimensional da região central das galáxias Seyfert NGC1068 e NGC2110
(Universidade Federal de Santa Maria, 2013-07-15)
In this work, we present a two-dimensional mapping of the central region of the active galaxies
NGC 1068 and NGC 2110, using near infrared integral field spectroscopy with the instrument NIFS
(Near-infrared Integral Field ...
