Powder X–Ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), scanning electron microscopy (SEM), UV–vis absorption spectrum, photoluminescence (PL) spectrum, Fourier transform infrared spectroscopy (FTIR), thermogravimetric and differential scanning calorimetry (TG–DSC) were used to characterize the as–obtained products.
Calcined fibers were characterized by thermogravimetric-differential thermal analyses, Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). Results showed that fibers calcined at 600°C were apatite fibers.
The intercalating interaction between gelatin and montmorillonite (MMT) was simulated with ( -COO~-),-NH~+_3 and -OH groups of low molecules such as lauric acid, laurylamine and lauryl alcohol. The results of X-ray diffraction (XRD)and fourier transform infrared spectroscopy (FTIR) indicated that their interaction sequence was -COO~->-NH~+_3>-OH>-COOH.
In this paper, pulsed laser deposition and pulsed laser ablation and synthesis deposition were used to prepare HA films. The microstructures of HA films were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), electron probe microanalysis (EPMA), fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and high resolution electron microscopy (HREM).
Both monomers and polymers were characterized by Fourier transform infrared spectroscopy, 1H nuclear magnetic resonance, and elemental analysis measurements, and their structures were identified.
Fourier transform infrared spectroscopy and thermal gravimetric analysis were used to detect the imidization and thermolysis processes of PAA/PU blends under thermal treatment.
Fourier transform infrared spectroscopy analysis showed that DHPDMS had been incorporated into the polyurethane chains.
Fourier transform infrared spectroscopy (FTIR) results show that the special coupling agent POE-g-MAH, in a chemical reaction with CaCO3, can produce an interfacial layer stronger than simple physical adhesion attained with usual coupling agents.
The properties of the modified CNC were characterized by means of Fourier transform infrared spectroscopy (FT-IR), 13C nuclear magnetic resonance (NMR), transmission electron microscopy (TEM) and thermogravimetric analyses (TGA).
Development of capillary supercritical fluid chromatography/Fourier transform infrared spectrometry
The feasibility of a new technique, supercritical fluid chromatography/Fourier transform infrared spectrometry (SFC/FTIR), for separation and identification of nonvolatile and labile compounds in complex mixtures is discussed in this report.
The use of deuterated solvents in high-performance liquid chromatography-Fourier transform infrared spectrometry
The coupling of carbon dioxide supercritical fluid chromatography with Fourier transform infrared spectrometry (SFC-FTIR) is a powerful tool for the separation and on-line identification of non-volatile compounds.
