This review provides an overview and update regarding the use of some nanomaterials as biosensors, which have shown attractive results over the last few years.

The interfacial electron transfer reactions that take place in dye-sensitized TiO₂ molecular devices for solar energy conversion govern their efficiency. This review visits general aspects of these reactions.

In this study, an aluminosilicate residue of high voltage transformer insulators was used as an adsorbent in basic dye solutions and its parameters and adsorption properties were investigated during the process.

Biomass with K₃PO₄ subjected to different pretreatments resulted in increased phenolics yields.

Environmental monitoring of potentially toxic elements in water and Mytella charruana (sururu) from Mundaú lagoon (Maceió, AL, Brazil).

Development and validation of a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of sacubitril, valsartan and LBQ657 (a metabolite of sacubitril) in human plasma and its application to clinical study.

A series of novel 2-(thiophen-2-yl)-4H-chromen-3-yl-sulfonate derivatives (4a-4n) were synthesized and investigated for their in vitro free radical scavenging potential as well as cytotoxic efficacies against selected cancer cell lines.

A hybrid molecular imprinted polymer was optimized by factorial design to obtain the best conditions for caffeine extraction in surface water. Caffeine is an important emerging contaminant used as anthropogenic marker to indicate the presence of water supplies contamination.

This research in coordination chemistry reports the synthesis and characterization of a new Ru^II complex, together with the evaluation of its catalytic activity for hydrogenation of ketones in real time by ¹H nuclear magnetic resonance (NMR).

Chromone derivatives were synthetized and their photoprotective properties were evaluated.

Cartridges with oxidized and non-oxidized cellulose were studied with different zeolites to assess some properties of such hierarchical materials.

The electrospray ionization mass spectrometry (ESI-MS) and principal component analysis (PCA) provided a simple and effective approach to screening alkaloid-producing endophytic Penicillium strains from Amazon medicinal plants.

Alkaloids are virtually perennial, with qualitative variation during the year, and flavonoids accumulate during the rainy season.

The remarkable current density of BiVO₄ electrode, associated with its morphological and structural properties of the electrode surface.

Advanced oxidation processes with persulfate enable the treatment of textile dye wastewater, which allows its reuse.

The biodegradation of the polycyclic aromatic hydrocarbon (PAH) fluoranthene by fungi from a Brazilian tropical peat was reported with the identification of metabolites.

Human whey obtained by ultracentrifugation, and its characterization regarding triacylglycerol profile and proximate and fatty acid composition.
