In this review, the methods for the production of selenium-quinones and tellurium-quinones and their biological applications until 2021 are highlighted.

The contamination of maize with antibiotic residues from soil, especially ciprofloxacin and enrofloxacin, may result in reduced production and damage to the crop. In this work, a reliable reversed-phase high-performance liquid chromatography method with fluorescence detection (HPLC-FLD) to monitor these residues in maize was validated.

Zn_xFe_(3-x)O₄ photocatalyst is remarkably active in degrading the indigo carmine dye in aqueous reaction medium containing H₂O₂ when irradiated by ultraviolet light.

Evaluation of nitrogen oxides in the air of five Brazilian urban centers, by passive sampling.

Development of a multivariate calibration model using net analyte signal (NAS) concept to quantify polymorphism of valsartan, a drug marketed in its amorphous phase.

The sediments from the Ipojuca River were analyzed by classical analyses and liquid chromatography-tandem mass spectrometry (LC-MS/MS) to evaluate sewage contamination levels.

This work describes the synthesis and application of an europium(III) complex, [Eu(TTA)₃(2-pyr)(H₂O)] and its application as potential luminescent sensor for detecting Pb^II and ethanol in gasoline fuel.

Research summary of the method development procedure for quantification of the elicitor salicylic acid (SA) in plant matrices through capillary electrophoresis.

Compounds isolated and identified by chromatographic and spectral analyses of the essential oils from the Amazonian species Aniba parviflora and Protium rubrum.

Synthesis of a series of alkylated and acylated derivatives of thymol and eugenol showed high antifeedant, larvicidal and ovicidal activities against Plutella xylostella.
