Two proton transfer salts and three copper(II) complexes have been synthesized and their antiglaucoma activities were studied in vitro.

Modified carbon black was used as an alternative nano-carbonaceous material for the preconcentration of trace levels of Cd²⁺ in different samples with posterior determination by flame atomic absorption spectrometry (FAAS).

Concentration evaluated of many compounds such as phytosterols, tocopherols, fatty acids and antioxidant, after different applications of fungicides.

Twelve Cirsium sp. methanolic extracts were analyzed using high-performance liquid chromatography to construct the appropriate fingerprint chromatograms. Obtained chromatograms were compared using various similarity and distance indices and the obtained results were compiled using principal component analysis (PCA).

Thin-film extraction procedure used for the determination of selected compounds from water samples.

Organic carbon (OC), N and P daily flow rates from Guanabara Bay to coastal ocean were obtained. Estimated OC, N and P flow rates are regionally and globally significant. Carbon (δ¹³C) and nitrogen (δ¹⁵N) isotopic composition and sterols reveal export of labile carbon, thus, of high nutritive value. The photo was taken during sampling.

Efficiency and kinetic of ethylenediaminetetraacetic acid disodium salt (EDTA) degradation showed considerable performance in the presence of phosphate modified nano titania compared to untreated nano titania probably due to better EDTA adsorption.

Herbicidal ionic liquids tend to prevent drops from running off the leaf and improve the wettability. Increasing time of contact with the surface of the leaves has a positive influence on the herbicide formulation efficacy.

Separation, detection, identification and quantification of acrylamide.

SD-SFO-DLLME (solvent-based demulsification and solidification of a floating organic drop combined with dispersive liquid-liquid microextraction): extractant and dispersing reagent were injected into the sample solution to extract the target compounds for HPLC-UV (high performance liquid chromatography with ultraviolet detection) analysis.

This graphical abstract summarizes the dangers of drinking "tape tea" due to the presence of neurotoxic and carcinogenic elements.

Ten new mesoionic derivatives from the 1,3-thiazolium-5-thiolate system with substituted acetamides were synthesized, had their potential as new drug evaluated in an in silico study and in their activity as antifungal against strains of Candida albicans.

Solid-phase peptide synthesis of dipeptide (histidine-β-alanine) as a chelating agent examined. Trityl chloride resin was used as a carrier.

The oxygen- and nitrogen-substituted indanes were prepared in good yield through iodine(III)-mediated ring contraction of 1,2-dihydronaphthalenes.

Continuous-flow production of solketal under atmospheric pressure by acid catalyzed ketalization of glycerol.

The metal contents and physicochemical properties were evaluated in samples of camu-camu from Pará (Amazonia region). The dendrogram shows the separation of 7 genotypes.

This scheme summarises the spectroelectrochemical results obtained for the samples of the hybrid materials based on polyaniline, chitosan and/or an organically modified clay.

The binding between serum albumin and the bioactive 19-nor-clerodane trans-dehydrocrotonin (t-DCTN) is weak and essentially due to hydrophobic interactions.

The additive substituent effect of phenylmercaptoderivatives of corannulene are investigated by spectroscopic and electrochemical techniques. The per-substituted phenylmercaptocorannulene is incorporated as a replacement for [6,6]-phenyl-C₆₁-butyric acid methyl ester (PCBM) in a photovoltaic device.

Using dereplication, gas chromatography coupled to mass spectrometry (GC-MS) and multivariate analyses by hierarchical cluster analysis (HCA) and partial least squares-discriminant analysis (PLS-DA), of 12 extracts from four Senna spp., hit compounds were identified and the steps of extract fractionation and purification of known compounds were avoided; therefore, in the prospect for new drug prototypes from biological sources, the research approach was improved.

Green online pre-concentration of rare earth elements REEs and uranium followed by inductively coupled plasma optical emission spectrometry (ICP OES) determination in environmental samples.

Steam explosion with or without dilute phosphoric acid resulted in a good pretreatment performance of cane bagasse. High hydrolysis and fermentation yields were obtained from water-washed steam-treated substrates but the pretreatment water solubles were highly inhibitory. Freeze-drying water-soluble furan compounds and acetic acid to non-inhibitory levels.

Overview of Chromophoreasy: a simple, practical and reliable program that detects and integrates chromatographic and electrophoretic peaks.

A multiproduct calibration based on ultraviolet spectroscopy and Tillman's titration as reference method was developed to predict vitamin C in industrialized juices.

The saturation transfer difference nuclear magnetic resonance (STD NMR) method was report for lipase-amide interaction as a first-pass design method in the enzymatic kinetic resolution of amines.
