Forsterite amorphisation by ion irradiation: Monitoring by infrared spectroscopy

Non-invasive monitoring of brain temperature by near-infrared spectroscopy

Optical techniques are promising methods for measuring tissue temperature noninvasively due to the transparency of tissue to near infrared-light and the temperature dependent light-absorbing properties of endogenous absorbers, particularly water. Besides being noninvasive, the instruments are compact and portable, permitting bedside monitoring.

On-line fermentation monitoring by mid-infrared spectroscopy.

A new method for on-line monitoring of fermentations using mid-infrared (MIR) spectroscopy has been developed. The method has been used to predict the concentrations of glucose and ethanol during a baker's yeast fermentations. A completely automated flow system was employed as an interface between the bioprocess under study and the Fourier transform infrared (FT-IR) spectrometer, which was equi...

Monitoring Mineral Surface Phenomena by Infrared Reflection Spectroscopy

Determination of the mineral surface composition and structure at molecular and atomic levels and understanding adsorption mechanisms and kinetics are crucial to perform efficient separation processes for mineral beneficiation. This understanding is a fundamental requirement to make possible the prediction and control of the macroscopic surface properties that govern the efficiency of separatio...

Studies on the Formation of Mullite from Diphasic Al2O3-SiO2 Gel by Fourier Transform Infrared Spectroscopy

Al2O3-SiO2 diphasic gel was synthesized by sol gel route from aluminium nitrate and silicic acid following aqueous phase colloidal interaction. The precursor gel powder was thoroughly characterized by chemical analysis, measurement of surface area and bulk density measurement. The gel powder was further characterized by thermogravimetry, XRD diffraction stud...
