Collision-Induced Infrared Absorption by Molecular Hydrogen Pairs at Thousands of Kelvin

Abstract

Background: Non-linear dielectric spectroscopy (NLDS) of microorganism was characterized by the generation of harmonics in the polarization current when a microorganism suspension was exposed to a sinusoidal electric field. The biological nonlinear response initially described was not well verified by other authors and the results were susceptible to ambiguous interpretation. In this paper NLDS was performed to yeast suspension in tripolar and tetrapolar configuration with a recently developed analyzer.

“…Microwaves are part of the non-ionizing radiation and their frequency range spread from 100 MHz to 100 GHz (Kent et al, 2001). This technique has been also used in numerous investigation fields as medicine (Treo and Felice, 2009), pharmaceutical industry (Wojnarowska et al, 2011;Smith et al, 1995) and material sciences Labidi et al, 2011). In food technology, this technique has been used for controlling the osmotic dehydration of apple (Castro-Giráldez et al, 2011a) and kiwifruit (Castro-Giráldez et al, 2011b), for determining the fruit ripening of apple (Castro-Giráldez et al, 2010b), for determining the salt content in butter , characterization of alcoholic beverages and solutions of ethanol in water (Bohigas and Tejada, 2010), in the study of desalted cod (De los Reyes et al, 2009), to observe the behavior of beef meat during maturation (Damez et al, 2008), to monitor changes in the dielectric properties of whole meat across a temperature range (Brunton et al, 2006), to determine the dielectric properties of a whey protein gel, a liquid whey protein mixture and also to detect the whey protein denaturation (Bircan et al, 2001).…”
