The aim of the present study was to investigate the possibility of using infrared spectroscopy for detecting the irradiation of meats. Samples of beef meat containing fat were subjected to gamma irradiation at doses of 0, 1.5, 3 and 4.5 kGy at room temperature. Then irradiated and non-irradiated beef meat samples were examined by Fouriertransform infrared (FT-IR) spectroscopy post irradiation t...

Terahertz time-domain spectroscopy (THz-TDS) and Fourier transform infrared (FT-IR) spectroscopy were used to generate far-infrared and low-frequency spectral measurements of monomeric lysozyme and lysozyme fibrils. The formation of lysozyme fibrils was verified by the Thioflavin T assay and transmission electron microscopy (TEM). It was evident in the FT-IR spectra that between 150 and 350 cm(...

The FT-IR, FT-Raman and SERS Spectra of 1-Chloro 4-Flurobenzene (C6H4CLF) have been recorded in the range 4000-400cm -1 , the optimized geometry,frequency and intensity of the vibrtional bands of C6H4CLFhave been obtained by DFT levels of theory with complete relaxation in the 6-311**G basis sets. A complete vibrational assignment, aided by the theoretical frequency analysis, has been proposed....

We have studied the Fourier Transform Infrared (FT-IR) and the Fourier transform Raman (FT-Raman) spectra of stanozolol and oxandrolone, and we have performed quantum chemical calculations based on the density functional theory (DFT) with a B3LYP/6-31G (d, p) level of theory. The FT-IR and FT-Raman spectra were collected in a solid phase. The consistency between the calculated and experimental ...

Fourier transform-infrared (FT-IR) spectroscopy has become an important tool for rapid analysis of complex biological samples. The infrared absorbance spectrum could be regarded as a "fingerprint" which is characteristic of biochemical substances. In this study, Pseudomonas putida NCIMB 9869 was grown with either 3,5-xylenol or m-cresol as the sole carbon source, each inducing different metabol...

the knoevenagel condensation of aromatic aldehydes with barbituric acid, dimedone and malononitrile occurred in the presence of bf3/nano-γ-al2o3 at room temperature in ethanol. this catalyst is characterized by powder x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), thermal gravimetric analysis (tga), field emission scanning electron microscopy (fesem) and energy-disper...

Simultaneous positron emission tomography (PET) and fluorescence tomography (FT) for in vivo imaging of small animals is proposed by a dual-modality system. This system combines a charge-coupled device-based near-infrared fluorescence imaging with a planar detector pair-based PET. With [(18)F]-2-fluoro-2-deoxy-d-glucose radioactive tracer and the protease activated fluorescence probe, on the on...
