Four oils were treated with five inhibitors solutions and evaluated by rheology. These oils were fractionated by the SAP method (saturated, aromatic and polar) and the saturated fraction was analyzed by high resolution mass spectrometry (atmospheric pressure chemical ionization using a positive ionization mode (APCI(+)) Orbitrap) and two-dimensional gas chromatography coupled to quadrupole mass spectrometry (GC x GC-qMS).

Erythrosine photosensitizer (PS)-containing polycaprolactone (PCL)/upconversion nanoparticles (UCNPs)-apatite composite for biomedical applications in the therapy-stimulated bone repair and photodynamic therapy (PDT).

K₂MgSiO₄ was produced by impregnation of serpentinite rock with KOH and thermal treatment. New materials released K in a slow rate than KCl, showing potential as slow release K-fertilizers.

An easy-to-follow methodology for fish lipids analysis by nuclear magnetic resonance (NMR) spectroscopy is presented. Biological sample collection, sample preparation, lipid extraction, NMR spectroscopy analysis, statistical data analysis and the care needed in each step execution are explained in detail.

Geochemical investigation of tar balls collected in two distinct years (2012 and 2014) in a Brazilian beach using several analytical techniques suggesting that the area is subjected to frequent spill from the same source.

Environmental actions, related to the Ingá Mercantil legacy, led to a Zn reduction in surface sediments.

The successful fabrication of two silylated ruthenium(II)-neodymium(III) heterobimetallic complexes with excellent photophysical properties allow grafting onto any silicated matrix suggesting their application as new luminescent near infrared (NIR)-emitting biolabels.

New tetraphenylphosphonium (Z)-allyldithiocarbimates synthesized inhibit the germination of phytopathogenic fungi.

A voltammetric method was developed based on the adsorption of the complex of molybdenum(VI) with 8-hydroxyquinoline, using square wave cathodic stripping voltammetry. The concentration of the support electrolyte, frequency, amplitude and deposition time were optimized by factorial design in relation to the reduction of molybdenum(VI) current. The results obtained for the determination of Mo^VI in soils and leaves of vegetables show good agreement.

The amides from leaves of Piper tuberculatum are hydrolyzed by the weevil N. bipes and by caterpillars of H. hectorides but not bygeneralist grasshoppers.

With the addition of 0.01 mol L^-1 NaNO₂ in pH 1 to 5 HNO₃ solutions, the electrochemical behavior of X65 carbon steel transferred from the activation in the solutions free of NaNO₂ to the passivation in the solutions containing NaNO₂.

A fast, inexpensive, and ecological method for preparation of extract with high content of Nigella sativa quinones.

Thirteen new amidino pyrazolines were synthesized under ultrasound in 15-83% yield. Some examples showed promising antibacterial activity.

Different species of fishery residues present excellent catalytic activities in the synthesis of biodiesel and can represent a technological-socio-environmental solution for the coastal community of the Northeastern of Brazil.

Band structure and local density of states (LDOS), around the Fermi level, for (8.0) single wall carbon nanotube (SWCNT) plus ethinylestradiol molecule and estrone molecule, in most stable configurations.

Chemical identification and determination of the biomarkers associated with the cytotoxic potential of extracts.

Evaluation of the effect of extrusion on the discrimination of Sorghum bicolor by paper spray mass spectrometry.

The present study reports the high encapsulation efficiency and the in vitro release study of citronella essential oil in Pluronic^® F127 nanoparticles coated with chitosan-sodium alginate polyelectrolyte complex.

Essential oils rich in (E)-nerolidol were identified in different parts of M. leucadendra from Pernambuco, Brazil. Essential oils presented high toxicity against adults and eggs of T. urticae and P. xylostella

Nine 1,2,3-triazole derivatives were synthesized and had their fungicidal, phytotoxic and antiproliferative activities evaluated.

Sericin extracted from Bombyx mori cocoons was used for the development of a film for use in human skin.
