Effect of Densification Conditions on Physical Properties of Pellets Made From Sawmill Residues
Sawmill residues produced in wood processing of Pilon (Hyeronimaalchorneoides) and Eucalyptus (Eucalyptus spp) species, were used to fabricate pellets with experimental design equipment. Different manufacturing conditions ...
Densification of Mn-doped tin oxide films by conventional heating and microwave heating treatment
Mn(II) doped SnO2 thin films used for shielding fluoride glasses against corrosion were investigated by x-ray absorption spectroscopy (EXAFS and XANE)S at the Sn and Mn K-edges. The effect of firing treatment on the ...
Integration between the ethanol production and the energy co-generation through the energetical densification of lignocellulosic residues and gasification process
This chapter presents the energetic densification as an alternative for the use of lignocellulosic residues, such as the ones from ethanol production, so that they can be used in gasifiers, aiming towards the energy ...
Oportunidad para el desarrollo de terrenos islas en la comuna de Las Condes
(Universidad de Chile Instituto de la Vivienda, 2017)
This paper analyzes the effects and potential of a regulation intended to mitigate the consequences of a densification process that took place from 2003 within the context of a regulatory plan promoted by the municipality ...
Effect of cobalt(II) oxide and manganese(IV) oxide on sintering of tin(IV) oxide
Additions of 0.5 to 2.0 mol% of CoO or MnO2 onto SnO, promote densification of this oxide up to 99% of theoretical density. The temperature of the maximum shrinkage rate (TM) and the relative density in the maximum ...
Densification and coarsening of SnO2-based materials containing manganese oxide
(Elsevier B.V., 1998-01-01)
The present work presents results on natural sintering of tin dioxide ceramics, prepared by a chemical route or by conventional mixing and containing manganese (X-Mn = Mn/(Mn + Sn)(atomic) with 0 less than or equal to ...
DENSIFIED RADIATA PINE FOR STRUCTURAL COMPOSITES
(Universidad del Bío-Bío, 2006)
Informe de práctica académica en arquitectura el valor del patrimonio en el Panorama Rioplatense
This article is a reflection and a critical view of the different definitions, and plan ways to intervene in Latin American architectural heritage context taking as reference the city of Buenos Aires, for it deals with the ...
Sintering of cobalt and strontium doped lanthanum chromite obtained by combustion synthesis
Lanthanum chromite (LaCrO3) is one of the most adequate materials for use as interconnector in solid oxide fuel cell (SOFC) applications, due to its intrinsic properties, namely its good electrical conductivity and resistance ...
