Spectroscopic study and thermal behavior of trivalent lanthanides and yttrium(III) chelates of EDTA using TG-DSC, FTIR, and TG-DSC coupled to FTIR
(2013-07-23)
Solid-state compounds of yttrium and lanthanide chelates of ethylenediaminetetraacetic acid have been synthesized. Simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC), theoretical and experimental ...
Multi-analyte quantification in bioprocesses by FTIR spectroscopy using Partial Least Squares Regression and Multivariate Curve Resolution
(Elsevier Science, 2014-01)
This paper presents the quantification of Penicillin V and phenoxyacetic acid, a precursor, inline during Pencillium chrysogenum fermentations by FTIR spectroscopy and partial least squares (PLS) regression and multivariate ...
Development and validation of the quantitative analysis of ampicillin sodium in powder for injection by Fourier-transform infrared spectroscopy (FT-IR)
(Scientific and Academic Publishing, 2012)
This paper describes the validation of an innovative analytical method for ampicillin sodium in powder for injection quantification, using Fourier-transform infrared (FT-IR) transmission spectroscopy. This technique does ...
Study of coprolites from the araripe sedimentary basin through FT-IR spectroscopy and X-ray diffraction
(Soc Brasileira Quimica, 2007-01-01)
Coprolites are fossilized faeces that constitute an important source of palaeobiological informations. This paper describes the characterization of some coprolite materials originated from the Romualdo Member of the Santana ...
Evaluation of photo-induced crosslinking of thymine polymers using FT-IR spectroscopy and chemometric analysis
(Elsevier, 2012-09)
The photo-induced immobilization of 4-vinylbenzyl thymine (VBT) and 4-vinylbenzyl triethyl ammonium chloride (VBA) copolymers has been investigated with the aid of grazing-angle specular-reflectance FT-IR spectroscopy. ...
Monitoring changes in the cellular content of biomolecules during ageing with FTIR spectroscopy
(Elsevier Science, 2019-11)
Dietary regimens have proven to promote longevity in several eukaryotic model organisms including the budding yeast Saccharomyces cerevisiae. These interventions are effective strategies for preventing ageing and diseases ...
