Infrared spectroscopy: A tool for determination of the degree of conversion in dental composites
(2008-01-01)
Infrared spectroscopy is one of the most widely used techniques for measurement of conversion degree in dental composites. However, to obtain good quality spectra and quantitative analysis from spectral data, appropriate ...
Optical diagnosis of actinic cheilitis by infrared spectroscopy
(2016-12-01)
Actinic cheilitis (AC) is considered a potentially malignant disorder of the lip. Biomolecular markers study is important to understand malignant transformation into squamous cell carcinoma. Fourier transform infra red ...
Thermal and spectroscopic studies on solid ibuprofen complexes of lighter trivalent lanthanides
(Elsevier B.V., 2014-01-10)
Solid-state compounds of general formula Ln(L)(3), in which Lis ibuprofen and Ln stands for trivalent La, Ce, Pr, Nd, Sm and Eu, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), ...
FTIR Spectroscopy Applied in Remazol Blue Dye Oxidation by Laccases
(2012-12-17)
We have used FTIR with attenuated total reflectance (ATR) technique to analyze the decolourization process of Remazol Blue
dye (RBI 9) caused by the oxidative activity of laccase enzyme. It is known that laccases catalyze ...
Peak Separation by Derivative Spectroscopy Applied to FTIR Analysis of Hydrolized Silica
(Soc Brasileira Quimica, 2008-01-01)
Reliable spectral analysis is only achieved if the spectrum is thoroughly investigated in regard to all hidden and overlapped peaks. This paper describes the steps undertaken to find and separate such peaks in the range ...

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 ...
