Geochemistry of heavy metals in bottom sediments from streams of the western coast of the Rio de la Plata Estuary, Argentina
(Springer, 2001-12)
The fluvial system within the southwestern coastal sector of the Río de la Plata interacts with a very large and efficient mixing basin known as the Río de la Plata estuary. The region is a densely populated and productive ...
Bread Staling: Changes During Storage Caused by the Addition of Calcium Salts and Inulin to Wheat Flour
(Springer, 2018-11)
The objective of this work was to study changes in staling parameters of wheat bread formulated with different calcium salts (carbonate, citrate, or lactate) and inulin. The moisture content and texture of crumbs were ...
Methane catalytic combustion over CeO2-ZrO2-Sc2O3 mixed oxides
(Elsevier Science, 2019-10)
In this work nanostructured CeO2-ZrO2-Sc2O3 mixed oxides prepared by citrate complexation method are studied. The effects of the co-substitution of ZrO2 and Sc2O3 in the CeO2 lattice are assessed in terms of the reducibility ...

Food spoilage is a major issue globally and million of people suffer from food-borne infections. Hence, there is a need to search for novel and effective antimicrobial agents. Nanoparticles act as antimicrobial agent, which ...
Residue of manufacture of porcelain stoneware tiles as supplementary material for cement mortars
(Mohammed Premier University. Faculty of Science, 2018-01)
This paper presents the results of the chemical and morphological characterization of a residue produced during the manufacture of the porcelain stoneware tiles, and an alternative for its recycling as cement mortar addition ...
Water uptake behavior of layered silicate/starch-polycaprolactone blend nanocomposites
(John Wiley & Sons Ltd, 2008-02)
The water uptake behavior of biodegradable layered silicate/ starch-polycaprolactone blend nanocomposites was evaluated. Three different commercial layered silicates (Cloisite Na+, Cloisite 30B and Cloisite 10A) were used ...
Interface-Mediated Twinning-Induced Plasticity in a Fine Hexagonal Microstructure Generated by Additive Manufacturing
(Wiley VCH Verlag, 2021-10)
The grain size is a determinant microstructural feature to enable the activation of deformation twinning in hexagonal close-packed (hcp) metals. Although deformation twinning is one of the most effective mechanisms for ...
