Reduced order modeling of composite laminates through solid-shell coupling
(2017)© 2017, Journal of Aerospace Technology and Management. All rights reserved.Composite laminates display a complex mechanical behavior due to their microstructure, with a through-thickness variation of the displacement and ... -
Interface energy measurement of MgO and ZnO: Understanding the thermodynamic stability of nanoparticles
(2010)Nanomaterials have triggered excitement in both fundamental science and technological applications in several fields. However, the same characteristic high interface area that is responsible for their unique properties ... -
Effects of dependence between solid solution and surface excess in nanoparticles
(2010)In this work, samples of 10 mol% Mg-doped SnO2 were synthesized by Pechini's method and calcined at 500°C. Previous analysis suggests that the additive is preferentially located on the surface of nanoparticles as a surface ... -
Surface modification of SnO 2 nanoparticles containing Mg or Fe: Effects on sintering
(2007)Controlling the surface chemistry of oxide systems has emerged an effective tool to obtain desirable nanostructures and macro properties. A relatively simple way to achieve this is by using dopants that are prone to segregate ... -
Mean strain influence in low cycle fatigue behavior of AA7175-T1 aluminum alloy
(2007)This work evaluates the mean strain influence on total number of cycles to fatigue failure of AA7175-T1 aluminum alloy, based on empirical relationships developed by SWT, Morrow and Walker, that were used to adjust the ... -
Heat transfer, pressure drop and structural analysis of a finned plate ceramic heat exchanger
(2017)© 2016 Elsevier LtdHigh temperature heat exchangers (HTHE) constructed with ceramics can achieve higher temperatures of operation. Resistance to oxidation is the great advantage of using ceramics for this application. This ... -
Evaluation of mechanochemical and hydrothermal transformations in a wet-milled alumina by transmission electron microscopy and thermal analysis
(2017)© 2017 Trans Tech Publications, Switzerland.Milling and hydrothermal treatment of alumina powders in aqueous medium can result in surface transformations generating aluminum hydroxides. The aim of this work was to advance ... -
Gelcasting of stainless steel powder: An alternative to injection molding
(2010)The gelcasting process is a forming technique originally developed for the shaping of advanced ceramics into final products in attempts to overcome some of the limitations of conventional forming techniques used in powder ... -
Scaffolds’ production based on calcium aluminate blends and their biological properties
(2019)© 2019, Sociedade Brasileira de Engenharia Biomedica.Purpose: Scaffolds are artificial structures that provide a temporary template to withstand mechanical loads in vivo during the process of bone regeneration. They should ... -
Alumina foam coated with strontium oxide as a heterogeneous catalyst
(2012)The most common method to produce biodiesel is the transesterification of oils in the presence of methanol and a catalyst. Catalysts may be either homogeneous or heterogeneous, whereas the heterogeneous consume fewer ... -
Effect of gel chemistry on the machinability of green SiC parts produced by gelcasting
(2012)The growing interesting in the use of silicon carbide in automotive components, biomaterials, energy, among others, which demand the production of parts with complex geometry that are difficult to obtain by conventional ... -
The rheological behavior and surface charging of gelcasting alumina suspensions
(2008)Aim of this work is to investigate the effect of monomers containing either carboxylate (ammonium acrylate) or acrylamide (hydroxymethylacrylamide) functional groups on the surface charging and rheological behavior of ... -
ABS/HIPS blends obtained from WEEE: Influence of processing conditions and composition
(2016)© 2016 Wiley Periodicals, Inc.The recycling of acrylonitrile-butadiene-styrene (ABS) and high-impact polystyrene (HIPS) from postconsumer electronic equipment housing was investigated. A preliminary study of shot size and ...
