Chemical compositions of the propolis of Apis mellifera and Frieseomelitta longipes and determination of their biological activities.

Samples of biodiesel were first exposed to an accelerated oxidation process and then thermally decomposed. The final mass measured on the weight loss curve was used for assessing its oxidative level.

Triazolic derivatives of eugenol were prepared and had their cytotoxicity evaluated.

Potential energy variation for triethylaluminum combustion under different temperatures in NVE-MD simulations.

Dye sensitized solar cell (DSSC) can be prepared with natural dyes, such as Hibiscus. Photovoltaic parameters and a model capable of predicting the adsorption mechanism of the dye on the TiO₂ surface are investigated in this paper.

The article describes the incorporation of the yttrium aluminum oxide doped with Yb³⁺ and Er³⁺ incorporated into polyamide membrane obtained by Additive Manufacture. This work presents potential applications to transform infrared radiation into visible, upconversion.

A novel helicate [Fe₂L₃]⁴⁺ resulted from the subcomponent self-assembly of a C₃-symmetric triamine, iron(II) and 2-formylpyridine. The supramolecular studies showed that the size, functional group and symmetry of guest molecules remarkably influenced the host-guest interaction patterns.

This work shows the use of lemon varieties as natural reducing agents for the preparation of gold nanoparticles from two different metallic precursors. UV-Vis spectra of the red colloidal solutions show bands at ~ 520 nm corresponding to particle sizes of 5-25 nm.

Waste seed oils of Spondias mombin presents mostly unsaturated fatty acid, phytosteroids and two new alkenyl phenols.

Allantoin was encapsulated with galactomannan extruded from Delonyx regia.

This review summarizes recent developments, in the last twenty years, about the Ferrier rearrangement reaction involving synthesis, mechanistic proposal and application of 2,3-unsaturated O-glycosides.

Environmental friendly methods for regioselective iodination of the 3,7,3',4'-tetramethoxy-quercetin. Neat reation and aprotic polar solvent selective C-6, protic polar solvent selective C-8 and excess iodine reagent selective di-iodination.

Leaching of spent lithium-ion batteries under mild experimental conditions using weak and strong acids. Co(II) was extracted by D2EHPA at pH ~5. Lithium salts can be directly precipitated from the raffinate.

Schematic representation of possible reaction pathways in the corrosion of carbon steel by hydrogen sulfide.
