Optimization of the extraction  process of   bioactive compounds present in ginger (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic      acid (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and chelating activity of Fe^II) followed by the characterization of the extraction, evaluation of cytotoxic activity and production of liposomes.

Vitamin and nutrient supplements have been increasingly consumed. However, these supplements may be contaminated with toxic elements such as mercury.

The multicomponent synthesis of isoxazol-5(4H)-ones using an imidazolium-type ionic liquid catalyst provided varying product yields under mild reaction conditions. Through principal component analysis (PCA), a weighted graph was generated representing the descriptors that influence the antimicrobial activity of the derivatives.

Despite coronavirus disease (COVID-19) closure of boards, trafficking of novel synthetic cannabinoids was still present, even inside prison facilities. During COVID-19 lockdown three synthetic cannabinoids were reported for the first time in Rio de Janeiro.

This study optimized and validated for the first time the solid-liquid extraction with low temperature purification (SLE-LTP) method to determine dinotefuran insecticide residues in soil samples.

A study to establish redox and thermodynamic properties of the protein denaturing agents dithiobutylamine and dithiothreitol was carried out on a glassy carbon electrode.

Nuclear magnetic resonance (NMR) and chemometrics determined the chemical profiles of different styles of beer. Ale and lager beers are differentiated.

New semisynthetic derivatives obtained from the diterpene stemodin, isolated from Stemodia maritima, and evaluation of the cytotoxic activity.

In situ production of methyl esters from crambe seeds applying dimethyl carbonate, as extraction solvent and acyl acceptor, and enzymatic catalyst.

This study investigates a series of compounds analogous to caffeic acid phenethyl ester, designed in-house, with promising potential as anticancer agents.

Glycerol-triethanolamine deep eutectic solvent allows the cross-coupling reaction to proceed under inorganic base-free conditions. Triethanolamine phenylboronates were formed in situ and cross-coupling products can be easily extracted with hexane.

Development of a Certified Reference Material (CRM) candidate in powdered egg matrix that meets the production minimum requirements to become a reference material, evaluating its homogeneity and stability, for application in physical-chemical analysis of total solids, fixed mineral residue and protein.

Schematic representation of the incidence of benzo[a]pyrene in olive oil and the employed method to determine its presence and concentration.

Indium from waste electrical and electronic equipment (WEEE) determination and recycling proposition.

Study of anti-ureolytic activity and the interaction of the Schiff base 4-(3-hydroxybenzylideneamino) phenol (3B4) and its amine derived (3B4a) against urease.

Magnetic crosslinked enzyme aggregates finding application on olive oil transesterification. It may be magnetically separated and reused for 6 cycles.

An efficient and green methodology for the use of cyanoacetic acid as active methylene group to aldol type condensation reaction and catalyst for Biginelli reaction was investigated in this study.
