Magnetostrictive behaviour of Fe73.5Si13.5B9Nb3-xMoxCu1 alloys
(Elsevier Science, 2010-08)
Magnetostriction, dilatation and calorimetric measurements were performed on FINEMET type as-quenched and heat treated ribbons. Nb was gradually replaced by Mo in order to study the influence of the refractory elements ...
Structural analysis of modified hydroxyapatite powders
(Pergamon-Elsevier Science Ltd, 2001-02)
In this work, the presence of structural defects in modified hydroxyapatite (HA) samples were studied. The behavior of HA samples with different chemical compositions was compared. Structural alterations were produced by ...
Occluded cobalt species over ZSM-5 matrix: Design, preparation, characterization and magnetic behavior
(Pergamon-Elsevier Science Ltd, 2007-10-05)
Co-containing molecular sieves with MFI structure was synthesized by the hydrothermal crystallization method and cobalt was incorporated in it by wet impregnation at different percentages. Thermal post-treatments were ...
Effect of 475°C embrittlement on the low cycle fatigue behaviour of lean duplex stainless steels
(Wiley Blackwell Publishing, Inc, 2018-02)
Lean duplex stainless steels (LDSSs) with lower nickel and molybdenum are less susceptible to suffer spinodal decomposition than standard duplex stainless steels. It is the purpose of this work to study the effect of thermal ...
Polycrystalline silicon thin films on glass obtained by nickel-induced crystallization of amorphous silicon
(Wiley, 2011-01)
In this work, we use the nickel-induced crystallization process to crystallize a-Si:H thin films at temperatures compatible with the utilization of glass substrates. Hydrogenated amorphous silicon films are deposited ...
Oxidation state characterization in Cr oxides by means of Cr Kb emission spectroscopy
(Elsevier, 2010-02)
High resolution Kb spectra of Cr oxide were measured using a non-conventional spectrometer. Theoretical spectra were obtained using the DV-Xa method in order to interpret the Kb spectrum structures. Kb spectrum structures ...
Rapid preparation of block copolymer templated mesoporous Zr1-xCexO2 thin films
(Royal Society of Chemistry, 2017-05)
A scalable, simple, robust and reproducible method is presented for the preparation of chemically homogeneous and ordered nanocrystalline and mesoporous Zr1-xCexO2 thin films. The method utilizes widely available commercial ...
Unsaturated polyester/bentonite nanocomposites: influence of clay modification on final performance
(Elsevier, 2013-01-29)
In this work, unsaturated polyester/bentonite nanocomposites were obtained and characterized. The bentonite used was unmodified and with different chemical treatments. The effects of these different chemical modifications ...
Characterization of starch from two ecotypes of andean achira roots (Canna edulis)
(American Chemical Society, 2009-07)
Starches from two ecotypes of achira roots (Canna edulis Ker-Gawler) were characterized and compared to commercial potato and corn starches. This included scanning electron microscopy (SEM) of starch granules and amylose ...
Alternative route for the synthesis of high surface-area eta-Al2O3/Nb2O5 catalyst from aluminum waste
(Elsevier Science Sa, 2016)
This paper describes an alternative route for the production of a high-surface-area eta-Al2O3/Nb2O5 catalyst synthesized from aluminum waste and niobium ammonium oxalate (NH4H2[NbO-(C2O4)(3)]center dot 3H(2)O). The effects ...
