Differentiation of argentine propolis from different species of bees and geographical origins by UV spectroscopy and chemometric analysis
(Elsevier, 2018-09)Bees collect vegetal resins that they mix with their wax and mechanical impurities to elaborate propolis, whose chemical composition is complex and variable depending on botanical/geographical origin, type of bee, time of ... -
Quantitative analysis of metals in waste foundry sands by calibration free-laser induced breakdown spectroscopy
(2017-05-01)Laser-induced breakdown spectroscopy (LIBS) was applied for quantitative analysis of the elemental composition of waste molding and core sands produced from industry as part of the casting process. To perform the analysis, ... -
UV-Vis spectroscopy and chemometric: a simple method to differentiate honey, partially ripe honey and nectars
(Ediciones INTA, 2023-12)Honey is a supersaturated solution of sugars that also contains small amounts of enzymes, vitamins, phenolic compounds (e.g., flavonoids), terpenes, organic acids and hydrogen peroxide. The presence of such substances ... -
Vibrational study of caffeic acid phenethyl ester, a potential anticancer agent, by infrared, Raman, and NMR spectroscopy
(2014-01)The structural and vibrational properties of caffeic acid phenethyl ester (CAPE) were studied using infrared and Raman spectroscopy in the solid phase and multidimensional nuclear magnetic resonance (NMR) spectroscopy in ...
