Structural Characterization of Membrane Proteins and Peptides by FTIR and ATR-FTIR Spectroscopy
2012Fourier transform infrared (FTIR) spectroscopy is widely used in structural characterization of proteins or peptides. While the method does not have the capability of providing the precise, atomic-resolution molecular structure, it is exquisitely sensitive to conformational changes occurring in proteins upon functional transitions or upon ...

Fourier transform infrared (FTIR) spectroscopy
Photosynthesis Research, 2009Fourier transform infrared (FTIR) spectroscopy probes the vibrational properties of amino acids and cofactors, which are sensitive to minute structural changes. The lack of specificity of this technique, on the one hand, permits us to probe directly the vibrational properties of almost all the cofactors, amino acid side chains, and of water molecules ...

FTIR microspectroscopic characterization of Spitz nevi
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015In the last 10 years, few efforts have been carried out to apply vibrational spectroscopy in the study of dermal pathologies in order to characterize the most relevant spectral markers for distinguishing benign from cancerous lesions. Spitz nevi are a special group of benign melanocytic lesions, characterized by spindled and/or epithelioid ...

FTIR analysis of carbonate precursors in manganite coprecipitation synthesis by FTIR spectroscopy
2021The simple perovskite oxides, manganites, are nowadays subject of extensive research because of their electrical, magnetic and photocatalytic properties. Manganites described with general formula A1-xSrxMnO3 (A = Ca, Ba, La) were prepared by the coprecipitation method.

Study of jojoba oil aging by FTIR
Analytica Chimica Acta, 2009As the jojoba oil was used in cosmetic, pharmaceutical, dietetic food, animal feeding, lubrication, polishing and bio-diesel fields, it was important to study its aging at high temperature by oxidative process. In this work a FT-MIR methodology was developed for monitoring accelerate oxidative degradation of jojoba oils.

An FTIR study of hexamethylenetetramine in porous silicon
physica status solidi (a), 2003In this work the results of an infrared study of porous silicon (PS) single layers and superstructures exposed at room temperature to air with saturated hexamethylenetetramine (urotropin) vapor for different exposure time are reported. It is shown that significant adsorption is achieved even at very low urotropin concentration (10-7 M).

2006 International Biennial Baltic Electronics Conference, 2006
A portable FTIR spectrometer system has been developed to provide rapid on-site spectroscopic information. Rather than taking the samples from the field to the lab for analysis, the portable instrument allows an analyst to take the lab to the field. Depending on the modification the system is capable to allow connection to any standard FTIR accessory ...

FTIR-microscopy versus FTIR-ATR-spectroscopy for the analysis of multilayer polymer films
Mikrochimica Acta, 1986Transmission FTIR-microscopy can be applied successfully for routine analysis of the different areas of a multilayer polymer film as used in packaging industry or for new flame resistant airplane wall covers and for other high tech applications. Using a microtome cut of approx.

FTIR-mittaustekniikka savukaasuanalytiikassa
1994Tutkimuksessa selvitettiin FTIR-mittaustekniikan soveltuvuutta savukaasuanalytiikkaan laboratorio- ja kenttäkokeiden avulla. Laboratoriokokeissa tutkittiin FTIR-analysaattorin havaittavuusrajoja, analyysin toistettavuutta, lineaarisuutta eri komponenteille ja synteettisten kaasuseosten analysointia.
