in this research calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. the mentioned nanoparticle were studied by fourier transform infrared spectroscopy (ftir) , x-ray diffraction (xrd), absorption and photoluminescence spectra (pl) and scanning electron microscopy (sem). the xrd patterns indicate a typical cubic fluorite structure and no other...

in this paper, tin dioxide nanoparticles were synthesized by a fast and simple co-precipitation method. for sno2 preparation, we used ammonia as precipitation agent and bis (acetylacetone) ethylene diamineas as capping agent. by changing in sncl4, acacen mole-ratio different morphologies were obtained. this semiconductor nanostructure has photo-catalyst activities and can degrade organic dyes a...

researchers have found a big interest in biological application of fourier transform infrared (ftir) spectroscopy. evaluating many diseases, staging them and studying the chemical structures of different formed compounds in diseases are some of the research applications of ftir. cancer is also one of these diseases. researchers are trying to set up ftir methods to detect and diagnose cancer cel...

Detection of animal mixtures in meatballs by using Fourier Transform Infrared Spectroscopy (FTIR spectroscopy) has been studied. This research aims to study the different markers fat characters containing mixture chicken fat, lard and rat fat. Sample preparation used Soxhlet extraction with n-hexane solvent distillation from solvent. The temperature is 70°C volume 200 mL. Fat samples were prepa...

Surface acoustic wave (SAW) measurements were combined with direct, in-situ molecular spectroscopy to understand the interactions of surface-confined sensing films with gas-phase analytes. This was accomplished by collecting Fourier-transform infrared external-reflectance spectra (FTIR-ERS) on operating SAW devices during dosing of their specifically coated surfaces with key analytes.

The synthesis of polynorbornene by ring opening metathesis polymerizations (ROMP) in the presence of 2 nd generation Grubbs catalyst-functionalized nanotube initiators, is reported. A full characterization of Grubbs catalyst-functionalized nanotubes was performed by FTIR (Fourier Transform Infrared Spectroscopy) and TG-DTGMS (Thermogravimetrical Analysis coupled with Mass Spectrometer), in orde...

16-Mercaptohexadecanoic acid (MHDA) and tripeptide glutathione conjugated with gold nanoparticles (Au-NPs) are characterized by Fourier Transform InfaRared (FTIR) spectroscopy combined with Surface-enhanced Raman scattering (SERS) spectroscopy. Surface Plasmon Resonance (SPR) technique based on FTIR spectroscopy has become an important tool in biophysics, which is perspective for the study of o...

ABSTRACT In this study, the effect of urbanization and environmental pollution on qualitative (structural) and quantitative changes of the Corylus avellana (hazel) pollen was investigated using scanning electron microscopy, Fourier Transform Infrared (FTIR) spectroscopy and curve-fitting analysis of amide I profile. The obtained spectroscopic results show significant variations in the fraction ...
