Estudo de junções túnel magnéticas com barreiras isolantes piezoelétricas de AlN
(Universidade Federal de Santa Maria, 2015-01-20)
We analyze the possibility of using aluminum nitride (AlN) as a piezoelectric tunnel barrier
in magnetic or non-magnetic tunnel junctions. Samples in the form of monolayers, bilayers,
multilayers and tunnel junctions ...
Um método multiestatístico para identificação de vias genéticas diferencialmente expressas
(Universidade Federal de Santa Maria, 2016-08-19)
The determination of the causes and origins of a given disease is a complex undertaking, considering
that there is a large number of genes engaged that interact with each other (Watson,
2006). Bioinformatics experts ...
Nanotubos magnéticos sintetizados por eletrodeposição em alumina anódica porosa
(Universidade Federal de Santa Maria, 2016-09-09)
Magnetic materials when reduced to the nanoscale promote the emergence of new properties
and the specific functionalization of these magnetic nanostructures are key tools in the
development of improved devices for ...
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 ...
Espectroscopia de impedância elétrica do VO2
(Universidade Federal de Santa Maria, 2010-01-18)
Impedance Spectroscopy has been performed at the metal-semiconductor transition of vanadium dioxide thin films. The samples have been deposited by reactive magnetron sputtering onto heated glass substrates. The crystallographic ...
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 ...

In this study, simulated to net radiation and energy flux in a region with rotation of crops, for two distinct periods: Period 1 (01 / Feb / 2009 to 31 / Jan / 2010) and period 2 (14 / Dec / 2009 to 28 / Apr / 2010). In ...
Variabilidade em escala associada com jatos de baixo nível e ondas de gravidade na camada limite noturna do Pantanal
(Universidade Federal de Santa Maria, 2011-08-22)
The Nocturnal Boundary Layer (NBL) turbulent structure above Pantanal Mato-Grossense, under
the influence of low-level jets (LLJ) and gravity waves (GW), is investigated. Experimental data
obtained during the Interdisciplinary ...
Estudo teórico de nanofitas de grafeno dopadas com Ni e Mn
(Universidade Federal de Santa Maria, 2010-07-16)
In this work we present the results of a systematic study of the stability, and the electronic, stuctural and magnetic properties of graphene nanoribbons doped with Ni (Ni/GNR) and Mn (Mn/GNR), through ab initio density ...
Leis de escala e análise do fenômeno de intermitência em turbulência bem desenvolvida
(Universidade Federal de Santa Maria, 2010-10-15)
This study presents a review of the statistical theory for the inertial range of welldeveloped
turbulent flows. The main focus of the study is on the experimental estimation of
the so called intermittency exponent through ...
