Thermoanalytical study of purine derivatives compounds
(Ecletica Quimica, 2004) [Artigo]Thermal methods of analysis are now used in a very large range of scientific investigations. In this work simultaneous thermogravimetry-differential thermal analysis (TG-DTA), X-Ray powder diffractometry and infrared ... -
A new acrylated monomer from macaw vegetable oil that polymerizes without external photoinitiators
(Journal of Polymer Research, 2021) [Artigo]The photopolymerization process has been widely studied due to its use in painting/coating, dentistry, creating photoresist materials and more recently in 3D printing. Therefore, new monomers have been synthesized to be ... -
Thermal stability and thermal decomposition of sucralose
(Ecletica Quimica, 2009) [Artigo]Several papers have been described on the thermal stability of the sweetener, C12H19Cl3O8 (Sucralose). Nevertheless no study using thermoanalytical techniques was found in the literature. Simultaneous thermogravimetry and ... -
Effect of titanium addition on the structure, microstructure, and selected mechanical properties of as-cast Zr-25Ta-xTi alloys
(Metals, 2021) [Artigo]Ti alloys are the most used metallic materials in the biomedical field due to their excellent biocompatibility associated with good corrosion resistance in body fluids and relatively low elastic modulus. However, the alloys ... -
AIE Effect by Oxygen Clustering in Vegetable Oil-Based Polymers
(ChemistrySelect, 2021) [Artigo]Vegetable oil has been widely used to synthesize monomers and polymers in different fields. Some authors have found different polymers in maleinized vegetable oil; however, they have not described the luminescent properties ... -
Epoxidation reaction in promising Brazilian biomass: decreased time and catalyst loading to produce renewable monomers
(Journal of Polymer Research, 2021) [Artigo]The syntheses of new materials using vegetable oils have increased due to technological interest and low environmental impact. Baru nut provides baru oil, rich in linoleic and oleic fatty acids that can be modified into ... -
