This paper presents the results of chemical analyses of the organic and inorganic fractions of pigment residues found in three archaeological sites located in the Beagle Channel region, Tierra del Fuego, Southern South ...

Archaeological objects require the design of non-destructive strategies for their study since they are part of the cultural heritage. In this work, we present a characterization strategy that minimizes the risk of damage ...

Scum is a residue generated during the anaerobic treatment of domestic effluents and requires periodical removal in order not to harm the process efficacy. This study aimed to use the scum ashes generated from Upflow ...

This paper presents the results obtained during the development of a didactic, interdisciplinary and contextualized alternative, using an approach that promoted elements of the Science-Technology-Society (CTS) and History ...

Zinc phosphate and related compounds have achieved wide application as suitable replacements for toxic and pollutant zinc Chromates and lead oxides which were employed as anticorrosive pigments for paints. The behaviour ...

The purpose of this study is to investigate the thermal performance of cool colored acrylic paints containing infrared reflective pigments in comparison to conventional colored acrylic paints of similar colors (white, brown ...
