Characterization of soluble and insoluble fibers in artichoke by-products by ATR-FTIR spectroscopy coupled with chemometrics
(Taylor & Francis, 2021-11)
The objective of this study was to characterize the insoluble and soluble dietary fiber present in Argentine and Italian artichoke (Cynara scolymus) by-products by comparing chemical analysis and ATR-FTIR spectroscopy. ...
A comparative investigation of metal-support interactions on the catalytic activity of Pt nanoparticles for ethanol oxidation in alkaline medium
(2016-04-15)
The effects of interactions of Pt nanoparticles with hybrid supports on reactivity towards ethanol oxidation in alkaline solution are investigated. Studies involve catalysts with identical Pt nanoparticles on six hybrid ...
Changes of physical properties of glass surfaces exposed to KNO3 vapors
(Elsevier B.V., 2006-08-01)
Modifications of glass surfaces were studied after exposure of samples to an atmosphere resulting from the decomposition of molten KNO3. The diffusion coefficient of K+ ions migrating into the surfaces of float glass and ...

FTIR characterization of Mexican honey and its adulteration with sugar syrups by using chemometric methods
(2012-12-17)
A chemometric analysis of adulteration of Mexican honey by sugar syrups such as corn syrup and cane sugar syrup was realized. Fourier transform infrared spectroscopy (FTIR) was used to measure the absorption of a group of ...
Aluminoxane-epoxi-siloxane hybrids waveguides
(Elsevier B.V., 2008-11-01)
Boehmite-GPTS (GKS-glycidoxypropyltrimethoxysilane) hybrids (BGS) have been prepared by the sol-gel methodology. Spectroscopic properties and structural features have been evaluated from the initial sols to xerogels as a ...

Organic and inorganic content of fluorotic rat incisors measured by FTIR spectroscopy
(Pergamon-elsevier Science LtdOxfordInglaterra, 2010)
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 ...
Novel techniques for drug loading quantification in mesoporous SBA-15 using chemometric-assisted UV and FT-IR data
(Elsevier Science, 2022-07-15)
Albendazole is a crystalline drug that is poorly soluble in water, thus the dissolution rate in gastrointestinal fluids is limited. Mesoporous materials loaded with poorly water-soluble drugs become an interesting strategy ...
