A rapid Fourier transformed infrared (FT-IR) attenuated total reflectance (ATR) spectroscopic is applied to predict the quantity of oil in fresh olive in tree. The analytical method is evaluated by use of validation samples with nearly quantitative oil. 80 samples of olives in oil content, which varies between 8 and 21%, picked up in the Moroccan region, were subjected to infrared analysis. Ana...

Extracellular matrix (ECM) is a key component and regulator of many biological tissues including aorta. Several aortic pathologies are associated with significant changes in the composition of the matrix, especially in the content, quality and type of aortic structural proteins, collagen and elastin. The purpose of this study was to develop an infrared spectroscopic methodology that is comparab...

in this paper, cuo nanoparticles  have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem).

the potential of fourier transform near-infrared (ft-nir) spectroscopy technique was applied to determine moisture and soluble solids content of shahani date fruit. spectral acquisitions were carried out in reflectance mode using a ft-nir spectrophotometer in the range of 12000- 4000cm-1. three different preprocessing methods namely: multiplicative scatter correction (msc), first and second der...

Soft X-ray absorption spectroscopy coupled with nano-scale microscopy has been widely used in material science, environmental science, and physical sciences. In this work, the advantages of soft X-ray absorption spectromicroscopy for plant biopolymer research were demonstrated by determining the chemical sensitivity of the technique to identify common plant biopolymers and to map the distributi...

The Fourier transform infrared spectra (FT-IR) and Fourier transform Raman spectra (FT Raman) of The 1-Propyl 4-Piperidone have been recorded in the regions 4000-400, 4000-100 cm -1 . The ultraviolet spectra (UV) spectra of the title molecule in the region 800-200 cm -1 . Utilizing the observed FT-IR and FT Raman spectra data, a complete vibrational assignments and analysis of the fundamental m...

Different yew species contain poisonous taxane alkaloids which serve as resources for semi-synthesis of anticancer drugs. The highly variable amounts of taxanes demand new methods for fast characterization of the raw plant material and the isolation of the target structures during phyto extraction. For that purpose, applicability of different vibrational spectroscopy methods in goods receipt of...

A collection of bacteria belonging to the genus Bacillus were analysed by diffuse reflectance absorbance and attenuated total reflectance Fourier transform infrared (FT-IR) spectroscopy in the mid-infrared. The diffuse reflectance absorbance method is a rapid whole organism fingerprinting method, which generates a biochemical profile of the bacteria, where samples are presented to the FT-IR spe...

OBJECTIVE Evaluation of early compositional changes in healing articular cartilage is critical for understanding tissue repair and for therapeutic decision-making. Fourier transform infrared imaging spectroscopy (FT-IRIS) can be used to assess the molecular composition of harvested repair tissue. Furthermore, use of an infrared fiber-optic probe (IFOP) has the potential for translation to a cli...
