(American Chemical Society, 2017)A very simple method of reductive amination, based on the Leuckart reaction, is reported. This method enables not only the reduction of graphite oxide but also results in reduced graphene oxide functionalized with amine ...
-
(TAYLOR & FRANCIS INC, 2005)The synthesis of new eight-membered cycle dibenzo[b,f][1,5]-diazocine-6(5H)-one derivatives 11, 12 was developed. The key step in this synthesis was the intramolecular cyclization of the amino aldehyde precursors 9,10 ...
-
(Wiley, 2016)The formation of redox-active, totally organic nanoparticles in water is achieved following a strategy similar to that used to form metal nanoparticles. It is based on two fundamental concepts: i) complexation through ...
-
(Elsevier, 2018-06-15)The graphene-AgVO3 nanocomposites (GA30) were synthesized by facile one-step chemical-bath method. SEM and TEM images of the synthesized nanocomposites indicate that this method is possible to anchor the AgVO3 nanoparticles ...
-
(Bentham Science, 2016)With the aim of finding new chemical entities based on coumarin and chalcone scaffolds, new hybrid compounds 2-5 were designed and synthesized. The trypanocidal activity of these compounds was tested against the epimastigote, ...

Fat deterioration in deep fat frying of «french fries» potatoes at restaurant and food shop sector (Instituto de la Grasa, 1999)The objective of this work was to know the deterioration of fats employed in deep frying of «french fries» potatoes at restaurant and food shop sector in Santiago (Chile), before the recent Chilean legislation became ...
-
(1998)The oil extracted from the fat-storage organ (fat body) of the bullfrog (Rana catesbeiana) was characterized for its fatty acid composition. The main fatty acids were palmitic (18.1%), stearic (4.1%), myristic (2.7%), oleic ...
-
(Wiley, 2020)Toluidine blue O (TBO) is a water-soluble photosensitizer that has been used in photodynamic antimicrobial and anticancer treatments, but suffers from limited solubility in hydrophobic media. In an effort to incrementally ...
-
(BLACKWELL PUBLISHING, 2008-07)The conformations of organic compounds determined in the solid state are important because they can be compared with those in solution and/or from theoretical calculations. In this work, the crystal and molecular structures ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2000-06)Reaction of CpFe(dppe)I with dithiopyridine in methanol and in presence of NH,PF, affords the new mixed valence complex {[CpFe(dppe)](2)-mu-S-Py}(PF6)(2) (1). Observation of an intervalence electron transfer affords the ...
-
(Elsevier B.V., 2013-06-15)The possibility of simultaneously determining seven concerned heavy polycyclic aromatic hydrocarbons (PAHs) of the US-EPA priority pollutant list, in extra virgin olive and sunflower oils was examined using unfolded ...
-
(1972)Potassic Chilean nitrate, a cheap natural product of northern Chile, was found to support the growth of the unicellular green alga Chlorella pyrenoidosa, a possible sheep fodder supplement in this region. Comparisons with ...
