Polyethylene/reduced graphite oxide nanocomposites with improved morphology and conductivity
(Elsevier, 2015)
The use of graphite and polyolefins as starting materials to prepare nanocomposites is convenient because both are inexpensive and have very different properties, one is conductive and the other is insulating. The formation ...
Commentary: Optical nanoantennas: From communications to super-resolution
(Society of Photo-Optical Instrumentation Engineers, 2011-06)
As silicon is the basis of conventional electronics, so strontium titanate (SrTiO3) is the foundation of the emerging field of oxide electronics1,2. SrTiO3 is the preferred template for the creation of exotic, two-dimensional ...
Influência dos materiais de fechamentos verticais e horizontais na eficiência energética de uma habitação unifamiliar térrea padrão normal em Santa Maria - RS
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2021-11-19)
More efficient buildings have a great impact on reducing national energy consumption, as they provide thermal comfort to their users with less electricity consumption. This work evaluated the impact that the use of EPS in ...
Three-Dimensional Imaging and Analysis of Electrical Trees
(2014)
Electrical trees are micrometre-size tubular channels of degradation in high voltage polymeric insulation, a precursor to failure of electrical power plant. Hence, electrical trees critically affect the reliability of power ...
Analysis of design variables for water-gas-shift reactors by model-based optimization
(Elsevier Science, 2007-11)
This work analyzes the water-gas-shift reactor design as component of the CO clean-up system of the ethanol processor for H2 production applied to PEM fuel cells. The WGS reactor constitutes the element of greater volume ...
Interdependência entre estrutura atômica e eletrônica de grafeno multicamada e isolantes topológicos
(Universidade Federal de Minas GeraisUFMG, 2015-02-24)
The structural and electronical properties of two materials with interesting bidimensional behavior were studied in this work: Multilayer Epitaxial Graphene and a topological insulator (Bi2Te3). Identification of the ...
Atenuação de ruído de impacto em pisos de edificações de pavimentos múltiplos
(Universidade Federal de Minas GeraisUFMG, 2008-08-29)
In Brazil as well in many countries, the development of constructive systems to provide acoustic comfort in buildings has been a permanent concerning nowadays in order to improve the life quality of its users. The annoyance ...
