Análise das propriedades dinâmicas e estruturais da água confinada entre placas hidrofóbicas
(Universidade Federal de Santa Maria, 2013-04-26)
In this work we studied the properties of confined water by graphene sheets via Classical
Molecular Dynamics. The main objective of this dissertation is to understand how the
structural and dynamic properties of confined ...
Estudo computacional da difusão de água em nanotubos de carbono induzida por gradiente de pressão
(Universidade Federal de Santa Maria, 2013-02-08)
In this work we present a computational study of the properties of water transport
across membranes formed of carbon nanotubes (CNT) armchair with different diameters,
when subjected to pressure gradients 80-400 MPa. This ...
A influência dos fenômenos meteorológicos de escala sinótica na escala micrometeorológica
(Universidade Federal de Santa Maria, 2013-04-30)
In this paper we present a study on the influence of synoptic scale weather
phenomena on the scale micrometeorological, to the town of Cruz Alta – RS. For this
we used the precipitation data, satellite ...
Simulações em laboratório de escoamentos em meios estratificados
(Universidade Federal de Santa Maria, 2013-10-02)
In the present thesis, two distinct scientific problem in fluid mechanics are studied using
laboratory observation techniques. In the first of them, a tank was used to simulate microburst
propagation. In the experimental ...
Estudo das propriedades estruturais, eletrônicas e termoelétricas de nanofios de PbSe e PbTe
(Universidade Federal de Santa Maria, 2013-04-29)
In this work we study simultaneously the structural, electronic and thermoelectric
properties of PbSe and PbTe nanowires, analyzing the quantum confinement effects, the
dependence with the planar stoichiometry and the ...
Variações espaciais de propriedades físicas e químicas das nebulosas planetárias NGC 6302 e NGC 2440
(Universidade Federal de Santa Maria, 2013-08-30)
We present an analysis of the physical and chemical conditions of the planetary
nebulae NGC 6302 and NGC 2440 through spatially resolved spectroscopy. Long slit
spectrophotometric data were obtained with the Goodman ...
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 ...
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 ...
Estudo de exchange bias via magnetorresistência anisotrópica
(Universidade Federal de Santa Maria, 2013-08-15)
Anisotropic magnetoresistance (AMR) corresponds to the change of R in an ferromagnetic
material with the angle between electric current and magnetization. Sensors using this
effect are suited to detect both angular and ...
Dinâmica de paredes de domínios sob o efeito de correntes elétricas
(Universidade Federal de Santa Maria, 2013-11-28)
In this work, we have measured the domain wall velocity in the low field regime and studied
the domain wall dynamics in Joule-annealed amorphous glass-covered microwires with positive
magnetostriction. Such microwires ...
