The effect of wall thermal capacity and thermal resistance in the energy efficiency of small office
(AshraeDoha, Qatar, 2014-02-24)
Historically, many ancient civilizations erected buildings that happened to have high thermal inertia. In places with high daily amplitude of air temperature and intense solar radiation, buildings made of heavy elements ...
Graphite dispersions as a basis for development of high thermal conductivity fluids
Both conductivity and thermal resistivity measurements of commercial graphite dispersions in non-aqueous polar fluids and non-polar fluids were carried out. Fluids exhibiting different densities as: mineral oil, ethylene ...
New additive type amorphous-carbon/Zn modifier of the thermal conductivity of alcohol fuel
A functional inorganic-additive modifier of the thermal conductivity of biofuel type alcohol anhydrous was developed based on an amorphous carbon nanocomposite containing dispersed zinc. Dispersion and modification of ...
Al2O3 obtained through resistive evaporation for use as insulating layer in transparent field effect transistor
(Trans Tech Publications Ltd, 2014-01-01)
Alumina thin films have been obtained by resistive evaporation of Al layer, followed by thermal oxidation achieved by annealing in appropriate atmosphere (air or O-2-rich), with variation of annealing time and temperature. ...
Electrical and Mechanical Properties of Post-annealed SiC(x)N(y) Films
(Trans Tech Publications Ltd, 2009-01-01)
Amorphous SiC(x)N(y) films have been deposited on (100) Si substrates by RF magnetron sputtering of a SiC target in a variable nitrogen-argon atmosphere. The as-deposited films were submitted to thermal anneling in a furnace ...
Fatigue Performance of AISI 4340 Steel Ni-Cr-B-Si-Fe HVOF Thermal Spray Coated
Coatings are deposited on high strength materials to improve the surface degradation resistance of several elements. As a consequence, the fatigue strength of coated materials is significantly influenced by internal residual ...
Estudo das características morfológicas dos pites nos materiais resistentes à corrosão
This paper has as a purpose a new alternative technique development to characterize pitting corrosion evolution, aiming classification, size and determination of morphological parameters which rule pits increase. In this ...
Thermal tool for evaluation of essential oils of Eucalyptus spp susceptible and resistant to Glycaspis brimblecombei attack.
(In: CONGRESSO BRASILEIRO DE ANÁLISE TÉRMICA E CALORIMETRIA, 10.; CONGRESSO PAN AMERICANO DE ANÁLISE TÉRMICA E CALORIMETRIA, 4., 2016, São Paulo. Trabalhos. [S.l.]: ABRATEC, 2016., 2016)
EVALUATION OF HVOF SPRAYED WC-13Co-4Cr AND HARD CHROMIUM ELECTROPLATED ON STAINLESS STEEL 15-5PH FATIGUE STRENGTH
Fatigue failure is the result of a crack initiation and propagation as a consequence of cyclic loading. In the aeronautical industry, for components like landing gear, fatigue strength is an important parameter to be ...
