Several calibration strategies have been reported in the literature over the last few years to improve quantitative analysis using laser-induced breakdown spectroscopy (LIBS).

The adsorption and subsequent removal of amoxicillin from aqueous solution was investigated using nickel ferrite (NiFe₂O₄) nanoparticles.

(1S,2R)-Ephenamine was synthesized starting from commercially available chiral amino acid through straightforward procedures on a six-step methodology.

Gunshot residue (GSR) was analyzed with wavelength dispersion X-ray fluorescence spectrometry (WDXRF), discriminated according firearm/cartridge type by principal component analysis and classified as GSR and non-GSR by k-nearest neighbors (k-NN) method.

The fluorimetric method proved to be simple, rapid, and sensitive for determination of the total antioxidant capacity of drinks based on thiamine oxidation inhibition.

Representation of a valid methodology for determining Cr^III and Cr^VI in sewage sludge samples by high performance liquid chromatography, inductively coupled plasma tandem mass spectrometry (HPLC-ICP-MS/MS).

Conversion of hydnocarpic acid into a triazole compound 8 with antiproliferative activity (concentration able to inhibit 50% growth (IC₅₀) = 63.96 ± 3.98 µM) against lung adenocarcinoma (A549).

Regarding the adulteration increase, it is essential to assess the guarantee levels declared by the manufacturers in the packaging of its products using analytical techniques.

Solid phase extraction followed by high-performance liquid chromatography with diode array detection (SPE-HPLC-DAD) method was validated and applied to endocrine disruptors environmental monitoring detection; hormones, pharmaceuticals and plastic compounds were found in high concentration in sewage treatment plants in Ceará, Brazil; biological treatments showed some efficiency in removal of endocrine disruptors compounds, although a post-treatment step is necessary.

The evaluation of environmental effects on the lipids of Amazonian wild fishes is presented. Focus was given on seasonal dynamics of the river, eating habits, and tissue.

Identification of flavonoids as inhibitors of Plasmodium falciparum enoyl-acyl carrier protein (ACP) reductase was evaluated by hierarchical virtual screening and intermolecular interactions contributed to the molecular recognition process.

Hg is quantitatively extracted from the sediment using a new chelating reagent dithiothreitol.

First-order derivative spectrum of lamotrigine and nicotinamide allows the simultaneous assay of the drugs in cocrystals.

Twenty-eight novel organosulfur compounds were synthesized from a molecular combination of cardanol and glycerol derivatives, with excellent yields and employing more environmentally friendly processes.

Steps of the cleaning treatment for produced water aiming the analyses of the polymer by size-exclusion chromatography.

Fifteen new piperine derivatives were planned and synthesized. The new compounds were obtained through the substitution reaction between δ-chloro-esters and potassium piperate, and were evaluated through in silico study and in vitro for antimicrobial activity.

The extraction of bioactive compounds present in rosemary (R. officinalis L.) using water as solvent comprises the context of green chemistry, as non-toxic solvent, high availability and low cost. It is necessary to optimize the extraction methods in order to obtain a high concentration of antioxidant compounds.
