Synthesis of heterogeneous catalysts derived from thermal treatments on hydrocalumite-type compounds intercalated with chloride and nitrate anions was carried out. The prepared catalysts were used in transesterification reactions to produce biodiesel.

Stabilization of oil-in-water emulsions containing N,N-diethyl-3-methylbenzamide (DEET)  using oppositely charged cationic cellulose nanofibrils (CCNF) and silica nanoparticles (SiNP) to allow extended and sustained release of DEET.

Paeonol derivatives were synthesized and their biological activities tested.

The removal of environmental contaminants such as Turquoise Blue dye from an aqueous medium can be made using LaNiO₃ material, with perovskite structure, and occurs due to electrostatic interactions between both.

Effect of pasteurization, lyophilization and spray-drying processes on the lipid profile of colostrum, transitional and mature human milk.

Hypochlorous acid (HClO) is an endogenous oxidant, and nicotine is the primary addictive component of tobacco smoke. Nicotine catalyzes the chlorination of biomolecules. This paper describes the mechanism of the catalytic effect of nicotine.

After a partial lockdown decree in Rio de Janeiro, reductions in pollutant sources were the main factor explaining lower concentrations of criteria pollutants. Meteorological conditions, similar to previous year, favor pollutant dispersion by sea breeze.

Synergistic effect of poly(ethylene-co-vinyl acetate) (EVA) copolymer and asphaltic residue from refinery on the reduction of pour point.

The α-MoO₃ support employed in this work allows the synthesis of potentially active and selective Au-Pd catalysts for the aerobic oxidation of cinnamyl alcohol under base and solvent-free conditions.

Carbon dots from Pilosocereus gounellei were used to develop a fast, low-cost, eco-friendly fluorescence flow-batch method for the determination of tannins in teas.

Samples of biomass sorghum BRS716 were submitted to fast catalytic pyrolysis to produce a bio-oil rich in hydrocarbon or phenolic compounds after optimizing the suitable critical process parameters using a response surface methodology approach.

Chemometric tools make it possible to differentiate the luminescent markers inserted in the ink, creating a document encoding process.

Tetragonisca angustula stingless bee honey collected in dry and rainy periods were subjected to analysis of physicochemical parameters, phenolic content, identification of phenolic compounds by high-performance liquid chromatography with ultraviolet detection (HPLC-UV) and glioma cell inhibitory effect.

Cariniana estrellensis seedlings are used in forest restoration programs in the Atlantic Forest biome. We used rapid analysis by nuclear magnetic resonance and liquid chromatography coupled to diode array, charged aerosol, and mass detection to provide the first data on secondary metabolism from C. estrellensis. We identified hydrolysable tannins, hydroxycinnamic acids, and flavonoids.
