The aim of this work was to investigate the relationship between the calculated molecular descriptors (geometrics and electronics) for 21 rutaecarpine analogous synthesized

However, the real predictive ability of the HQSAR model derived with the 207 training set molecules was assessed by predicting logBB values of an external test set of 48

Short reaction times, good to excellent yields, safe process and simple workup make this method an attractive and useful contribution to present organic synthesis of 5-substituted-1

The demulsification test with the oil phase composed of the C5 asphaltenes fraction presented only a small phase separation (approximately 20%), which was expected since

Cloud point extraction has been applied for speciation of organic and inorganic Se in vitamin tablets prior Se determination by fluorometry; 4 total Se determination in acid

In this study, amperometric cholesterol enzyme electrode based on poly( o -phenylenediamine) film was prepared for the determination of total cholesterol content in serum samples.

The extraction and derivatization conditions were optimized using experimental designs, such as: extraction time and sample temperature of 5 min and 170 ºC, fiber recoat

Excitation energies of the lowest singlet states and oscillator strength ( f ) of ZnPc molecule with and without solvent (IEFPCM/DMSO), obtained with
