Synthesis, thermal behavior and spectroscopic study of trivalentlanthanide and yttrium(III) α-hydroxyisobutyrates, in solid state
(2013-08-27)
Thermal and spectroscopic studies on solid trivalent lanthanides and yttrium(III) α-hydroxyisobutyrates, Ln(C4H7O 3)3·nH2O were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), ...
Multivariate curve resolution applied to kinetic-spectroscopic data matrices: Dye determination in foods by means of enzymatic oxidation
(Elsevier Science, 2017-07)
In this work, the combination of chemometric techniques with kinetic-spectroscopic data allowed quantifying two dyes (tartrazine and carminic acid) in complex matrices as mustard, ketchup, asparagus soup powder, pumpkin ...
A user-friendly excel spreadsheet for dealing with spectroscopic and chromatographic data
(2019-11-15)
A user-friendly interface was developed in Excel (Microsoft Office) to deal with spectroscopic and chromatographic data. The Excel spreadsheet includes baseline correction, area and height determination, and identification ...
The Gaia-ESO Survey: Spectroscopic-asteroseismic analysis of K2 stars in Gaia-ESO
(European Southern Observatory, 2020)
Context. The extensive stellar spectroscopic datasets that are available for studies in Galactic Archeaology thanks to, for example, the Gaia-ESO Survey, now benefit from having a significant number of targets that overlap ...

Spectroscopic study of early-type multiple stellar systems. I. Orbits of spectroscopic binary subsystems
(EDP Sciences, 2014-03)
Context. The present knowledge of stellar properties and dynamical structure of early-type multiple stellar systems is insufficient to offer useful statistical constraints for stellar formation models.
Aims. To increase ...
Thermally induced solid-state transformation of cimetidine. A multi-spectroscopic/chemometrics determination of the kinetics of the process and structural elucidation of one of the products as a stable N3-enamino tautomer
(Elsevier Science, 2015-05)
Exposure of cimetidine (CIM) to dry heat (160-180 °C) afforded, upon cooling, a glassy solid containing new and hitherto unknown products. The kinetics of this process was studied by a second order chemometrics-assisted ...
