Aldol condensation of furfural with acetone catalyzed by amines.

A new formulation for controlled drug delivery from water-swellable matrix systems was proposed.

The protonation of the carbonyl moiety in the succinic acid activates the carbonyl carbon atom for nucleophilic attack of n-butanol followed by the desorption of the succinic acid monobutyl ester. After a new esterification process, the generated dibutyl succinate separated from the surface active sites of the catalyst.

Seven compounds were isolated from Casearia arbórea using chromatographic methods and the antimicrobial activity of kolavelone, a clerodane diterpene, was evaluated.

A simple fluorescent sensor L showed good selectivity toward trivalent metal ions (such as Al³⁺, Fe³⁺, Cr³⁺, La³⁺ and Ce³⁺) over other monovalent or divalent metal ions.

Computational screening of solvents through full SMD calculations can be an useful approach for finding the best solvent of a chemical reaction.

With the reaction the PCBs are partially dechlorinated, forming less chlorinated congeners and aryl glycol compounds by the chemical bonding to the polyethylene glycol.

Extraction and pre-concentration of pesticides in surface water samples by SPE-HPLC-UV, using a low-cost lab-made SPE sorbent.

Waste and residual triacylglycerols can be a valuable feedstock source to produce biodiesel. One of the main chemical aspects of quality is the oxidative stability of FAMEs during of storage process. We evaluate some specific conditions that can promote it.

CO₂ sorption using ionic liquid ([mbmim][Tf₂N] and [bmim][BF₄]) with glass microspheres K20 as surface area extenders.

Lanthanoid organic frameworks (LOFs)* stand out as an important class of functional materials due the optical, magnetic and redox properties. The main properties of these materials as, sensors, catalysis, luminescence and so on, is described in this review.

Four alternative biomasses were applied in undergraduate organic chemistry experiment for oil extraction and biodiesel production. Infrared and hydrogen nuclear magnetic resonance spectra of oils, oil and biodiesel and biodiesels were compared.

Pericyclic reactions can be classified according to the connectivity of reactants systems as connected atom reactions (CAR) and as not connected atom reactions (NOCAR). HOMO's topology is adequate to explain all CAR, while the HOMO-LUMO's topology explain all NOCAR.

Methylene Blue and Erythrosine B showed photodynamic action in the inhibition of microbial growth after LED light exposure in a simple and didactic experiment. It can be applied in Chemistry courses allying advanced researches with basic concepts.

1,2,4-Oxadiazoles are heterocyclic with a broad spectrum of applications. Given this, the present search aimed at analyzing the potential and evolution of the technology involved in oxadizoles application through research papers and publications of patent applications.
