Rietveld refinements of SnO(2) ceramic powders doped with ZnO, WO(3), CoO, Nb(2)O(5) and MoO(3)
(Oldenbourg Verlag, 2007-01-01)
Polycrystalline materials of SnO(2) doped with ZnO, WO(3), CoO, Nb(2)O(5), and MoO(3). were synthesized by solid state reaction. X-ray powder diffraction data were collected with Cu K(alpha) radiation from a Rigaku-Rint ...
Generation of 3D mixed element meshes using a flexible refinement approach
(SPRINGER, 2005-12)
This paper describes and discusses the main characteristics and implementation issues of a 3D mixed element mesh generator based on a generalization of the modified octree approach. This mesh generator uses primitive ...
A novel lecithin:cholesterol acyltransferase for soybean oil refining provides higher yields and extra nutritional value with a cleaner process
(Springer, 2020-07)
The growing demand for food and biofuels urges the vegetable oil processing industry to adopt cleaner technologies to mitigate the environmental pollution caused by chemical refining processes. Over the past decade, several ...
Reducing GHG global emissions from copper refining and sea shipping
(Elsevier, 2020)
Chile is the largest copper producing country of the world; and almost 50% of the copper it exports to the rest of the world is exported as copper concentrates to be smelted and refined abroad. However, 70% of the weight ...
Spline-based methods with adaptive refinement for problems of acoustics and fracture mechanics of thin plates
(Universidad de Chile, 2018)
Both the CAD software and FEM software have a significant impact on engineering nowadays. Even though both are powerful tools for design and analysis, the main drawback is that CAD geometries and Finite Element models do ...
Superplastic behavior of AZ31 processed by ECAP
(Elsevier, 2015-09)
Magnesium base alloys have reached an important development as structural materials the last years due to its good strength/weight relationship. On the other hand, superplastic forming has also acquired a technological ...
