A method for multi-element determination in biodiesel samples is proposed using energy dispersive X-ray fluorescence spectrometry after an extraction induced by emulsion breaking procedure.

Exposure routes to plasticizer migration from flexible plastic food and water packaging absorbed through the gastrointestinal system by consumers.

BiOCl nanosheets modified with AuCu nanoparticles were successfully designed and fabricated for water reduction of CO₂. The Au_xCu_y/BiOCl composites exhibited enhanced visible light absorption ability due to a surface plasmon resonance (SPR) effect. The Au_xCu_y/BiOCl composites could convert carbon dioxide to ethane (C₂H₆), while only CO was obtained over pure BiOCl nanosheets. In this study, the rate of C₂H₆ production (12.2 μmol h^-1 g^-1) and selectivity of C₂H₆ (75.7%) were obtained over the Au₁Cu₁/BiOCl photocatalyst under simulated sunlight illumination.

Glycerol from biodiesel production was used with brewery spent grains, a residue from the brewing industry, to produce a biodegradable plastic applicable for packaging and lining, adding value to the waste.

The newly synthesized imidazole based 1,2,3-triazoles were evaluated as carbonic anhydrase-II via comprehensive in silico investigations.

Total content of copper, iron, and zinc were determined in camapu (Physalis angulata), lipids and protein fractions by inductively coupled plasma emission spectrometry.

In this work, chitosan sorbent films were synthesized, characterized and used to retain Bordeaux S present in gelatin samples, followed by recording the films' images and quantifying the analyte by digital images analysis.

Performed procedures and type of flavonoids isolated from leaves and branches of Macrolobium acaciifolium (Fabaceae).

Development and validation of a sensitive and linear method to quantify four Maillard reaction markers in doce de leite by high pressure liquid chromatography with photodiode-array detection.

In silico modifications of molecules derived from beta-lactam compounds were carried out. These new molecules were docked with transpeptidase and beta-lactamase enzymes, and all of them showed a higher affinity for transpeptidase than the reference molecule (methicillin), but only two showed a lower affinity for beta-lactamase, and the two molecules that presented the best ranking docking results were subjected to molecular dynamics simulations to assess conformational stability.

Environmentally friendly and highly selective conditions for the reduction of nitroarenes to their respective primary amines.

Group of students discussing about the pharmaceuticals promoted as COVID treatment in Brazil (known as COVID kit), sample preparation, chromatography and environment.

Application of machine learning to build computational models capable of correlating chemical structures with the intrinsic activity of the molecule and thus making predictions of activity of molecules that have unknown biological activity.
