The nucleophilic reagent usually attack at the C-2 position with γ -pyrone ring opening followed by further transformation during the course of the reaction producing a variety

In this work, the acid and base-catalyzed soybean oil methylation methods was monitored via GC-FID and also by ambient sonic-spray ionization mass spectrometry (EASI-MS)3.

porphyrin was electropolymerized in a glassy carbon electrode by the cyclic voltammetry and subsequently used as a voltammetric sensor for detection and quantification

Therefore, both the MLR and GRNN models of − log k OH based on quantum chemical descriptors from ground states of reactants and radical transition states are successful

In general, the molecular docking results show that the assessed compounds are located in the active site of both enzymes, but in butyrylcholinesterase, the carbamate group is

A solid phase extraction method based on magnetic iron oxide nanoparticles (MIONPs) modified by sodium dodecyl sulfate (SDS) was developed for the preconcentration and

The aim of the present work was to investigate for the first time the historical development of combustion processes in the hydrographic basin of the Guanabara as recorded in
