Bimetallic Zn^II complexes with phenoxy-imine ligands were synthesized and used as initiators for lactide polymerization.

A nanostructured porous gold based electrocatalyst was fabricated via a facile electrochemical approach and an excellent activity with good stability for hydrogen evolution reaction was noticed.

Based on thymine-Hg²⁺-thymine binding mode (T-Hg²⁺-T), a sensitive aptamer biosensor was constructed by utilizing functionalized Au@Ag core-shell nanoparticles as labels for detection of Hg²⁺.

The oil from the kernel of macauba presents high stability to oxidation, property that is transferred to its biodiesel, which also presents low cold filter plugging point. Such properties are inherited by its blends with biodiesels obtained from other vegetable oils.

Cheeses made with saffron are expected to provide an added value for consumers, due to saffron bioactive compounds. This UHPLC method seems to be useful to detect saffron crocins in dairy products.

The nature of crystal packing of an heterocyclic chalcone, investigated by Hirshfeld surfaces, and its potential nonlinear optical properties.

A series of novel substituted isoxazoles were prepared and tested for in vitro anti T. cruzi activity. The lead compound is equally as potent as reference drug benzonidazole.

The more efficient interaction of the fillers based on hydrophobic surface nanostructures with the hydrophobic UHMWPE chains leading to a much higher dispersion of the filler particles throughout the polymeric matrix.

The concentration of Cu, Zn, Cr and Pb in different species of fish collected in the estuarine and limnic regions of the Sao Gonçalo channel in Pelotas City were determined.

Virtual screening applied to FDA-approved drugs allowed the inhibitor discovery for enzymes diguanylate ciclases involved in the bacterial biofilm formation.

Surface of the activated silica gel was grafted with the complex of MTD-APS. The custom made holes to the MTD remain on the surface of molecularly imprinted adsorbent.

Schematic model of a 2:1 layer structure of the organofunctionalized materials present in this work, suggesting the superficial acid sites created.

Polymerization reaction with a nickel-based catalyst supported on SBA-15 mesoporous materials.

Tetraethylenepentamine modified magnetic graphene oxide nanomaterial was prepared and it had a good adsorption ability to remove dyes in wastewater.

The current study investigated the antioxidant activity, acetylcholinesterase inhibition and quantum studies of thiosemicarbazones.

Lead content was evaluated in chicken viscera by GF AAS after solubilization with tetramethylammonium hydroxide (TMAH). Sample preparation was monitored by Raman spectroscopy and SEM-EDS.

Mass spectrometry analysis as additional tool for description and differentiation of tumor physiopathology: a comparative proteomic study between pheomorphic sarcoma, metastasis and healthy tissues.

Selenate and selenite enrichment in the Veneza Roxa lettuce was carried out and the mineral composition was evaluated using ICP OES, PCA and molecular modeling. Selenate-biofortified lettuce showed a synergetic effect with S and Mo while selenite-biofortified lettuce showed a synergetic effect with Mn, P, Mg and Ca.

Photocatalytic degradation of estrogens by suspended and immobilized TiO₂ were compared in aqueous and wastewater samples. The EE2 degradation products were monitored by GC-MS/MS.

A fast evaluation of the degree of unsaturation and the presence of oxidized products in oil samples by Raman spectroscopy, through the identification of marker bands, assigned by supporting of GC-FID analyses of standard fatty acids.

Chiral GC chromatogram of the peak discrimination of 2-methyl-6-undecylpiperidine trifluoroacetamide stereoisomers (synthetic standard mixture).

Thermal properties and kinetics of Al/α-MnO₂ nanostructure thermite was reported in this work. According to DSC curves, the heat release and onset temperature were measured. Then the changes of activation energy on extent of conversion (α) for kinetics of Al/α-MnO₂ thermite were obtained by using isoconversional method.

Metal carboxylate complex modified with nitrogen ligands used as catalyst to oxidative polymerization of drying oils.

Fractionation of essential oils from Eucalyptus grandis x E. tereticornis, and its parental taxa, by HPLC followed by GC-MS analysis using two columns in series, allowed to determinate the enantiomeric excesses of selected monoterpenes. Significant differences were found in the enantiomeric ratios in monoterpene alcohols between the three essential oils.
