Infrared Spectroscopy of Carbonaceous-chondrite Inclusions in the Kapoeta Meteorite: Discovery of Nanodiamonds with New Spectral Features and Astrophysical Implications
(IOP Publishing, 2018-03-22)
We report the finding of nanodiamonds, coexisting with amorphous carbon, in carbonaceous-chondrite (CC) material from the Kapoeta achondritic meteorite by Fourier-transform infrared (FTIR) spectroscopy and micro-Raman ...
Low-cost analytic method for the identification of Cinnamon adulteration
(Elsevier Science, 2020-12)
In this work, a novel low-cost and non-destructive method for true cinnamon authentication -based on Near-infrared diffuse reflectance spectroscopy and chemometrics- is presented. The use of cinnamon as a spice and flavouring ...
Parametric study of the gel-combustion synthesis of nanocrystalline ZrO2-based powders
(Elsevier Science Sa, 2011-12)
In this paper, we report a study of the effect on the powder morphology of zirconia based solid solutions of several parameters of the synthesis by gel-combustion routes, such as fuel, metal/fuel ratio, composition of the ...
Preformulation: The use of FTIR in compatibility studies
(South Asian Academic Publications, 2019-07)
Studies of active pharmaceutical ingredient (API) - excipient compatibility represent an important study in the preformulation stage of the development of new dosage forms. The potential physical and chemical interactions ...
Low Temperature Infrared Spectroscopy Study of Pyrazinamide: from the Isolated Monomer to the Stable Low Temperature Crystalline Phase
(American Chemical Society, 2010-01)
A structural and spectroscopic analysis of the anti-tuberculosis drug pyrazinamide (PZA) was carried out. The PZA molecule was predicted theoretically to possess two conformers differing by internal rotation around the C ...
Polymerization of an epoxy resin modified with azobenzene groups monitored by near-infrared spectroscopy
(John Wiley & Sons Inc, 2009-06)
New photosensitive materials containing photochromic azobenzene moieties were synthesized. For this purpose, an epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) was reacted with an azobenzene chromophore (disperse ...
Examining water in model membranes by near infrared spectroscopy and multivariate analysis
(Elsevier Science, 2018-03)
By exploiting the sensitivity of the NIR spectrum, particularly the first overtone of water, to the number and strength of hydrogen bonds, the hydrogen bond network and water polymerization in membranes of DMPA ...
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 ...
