Obtenção de polissacarídeos sulfatados da alga vermelha comestível Gracilaria birdiae e sua influência na formação e morfologia de cristais de oxalato de cálcio
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM BIOQUÍMICA, 2016-08-30)
The urolithiasis disease affects approximately 10% of the world's population and is strongly associated calcium oxalate crystals (CaOx). Until now, there is not an efficient compound that can be used to prevent this disease. ...
Ultrasound-assisted synthesis of novel chalcone, heterochalcone and bis-chalcone derivatives and the evaluation of their antioxidant properties and as acetylcholinesterase inhibitors
(2019)
The chalcone and bis-chalcone derivatives have been synthesized under sonication conditions via Claisen-Schmidt condensation with KOH in ethanol at room temperature (20-89%). The structures were established on the basis ...

Physical Properties of Monoglycerides Oleogels Modified by Concentration, Cooling Rate, and High-Intensity Ultrasound
(Wiley Blackwell Publishing, Inc, 2019-09)
The aim of this study was to investigate the effects of monoglycerides (MG) concentration (3, 4.5, and 6 wt%), cooling rate (0.1 and 10 °C/min), and high‐intensity ultrasound (HIU) application on physical properties of ...
Synthesis and characterization of SiO2 particles for the development of a novel sun skin protector enriched with antioxidants
(Elsevier, 2019-05)
This work is focused to study the influence of the reaction media, alkaline or acid media, the annealing temperature, and sonication treatment on size and morphology of silicon dioxide (SiO2) nanoparticles obtained by the ...
Ultrasound-assisted synthesis of novel chalcone, heterochalcone and bis-chalcone derivatives and the evaluation of their antioxidant properties and as acetylcholinesterase inhibitors
(Academic Press Inc., 2019)
The chalcone and bis-chalcone derivatives have been synthesized under sonication conditions via Claisen-Schmidt condensation with KOH in ethanol at room temperature (20–89%). The structures were established on the basis ...
Synthesis, characterization and cyclic voltammetry studies of helical carbon nanostructures produced by thermal decomposition of ethanol on Cu-foils
(Elsevier, 2019-12)
Cu-foils have been used intensively to fabricate graphene and other carbon nanostructures. Several routes have been implemented to improve the synthesis of such carbonaceous nanomaterials. We investigated the growth of ...
