This parameter was originally defined in the case of a single symmetric EPR line and used as a new datation method for organic matter in the field of exobiology. ... Electron Paramagnetic Resonance (EPR) is a non-destructive, non-invasive technique useful for the characterization of organic moieties in primitive carbonaceous matter related to the origin of life. ... Electron Paramagnetic Resonance (EPR) is a nondestructive and non-invasive technique which has indeed long been used for the study of paramagnetic defects (organic radicals) in carbonaceous materials ...doi:10.1186/1751-0473-8-15 pmid:23866970 pmcid:PMC3847542 fatcat:ea4qmej3xvcnreq7xtgrc3eqhm
We used electron paramagnetic resonance (EPR) for assessing the syngeneity of organic matter in cherts that have a metamorphic grade no higher than greenschist. ... We concluded that EPR is a powerful tool to study primitive organic matter and could be used in further exobiology studies on low-metamorphic grade samples (from Mars for example). ... The authors wish to thank Frederic Mentink-Vigier for his constructive discussions on EPR experiments and the TGE-RENARD facility. ...doi:10.1089/ast.2012.0855 pmid:23397956 pmcid:PMC3582280 fatcat:fb7whwvh5reljg4mehtasb7v3i
At low shear rates the global orientation parameters, , , are close to zero, but at a critical shear rate which shows some dependence on the temperature, there is a marked increase in orientation with ... However, a flow aligning regime is not attained for the shear rate range considered here (from 0.1 to 190 s -1 ). ... order to determination of suitability for use in electrical engineering and to increase the efficiency of energy management". ...doi:10.52340/ns.2010.04 fatcat:ghwwgjzlujaxpf3g3l5hh5ky6m
Proceedings of the 71st International Symposium on Molecular Spectroscopy
Molecular spectroscopy has been a powerful tool in the study of molecules in gas phase, condensed phase, and at interfaces. ... The transition from in vitro spectroscopy to spectroscopic imaging of living systems is opening new opportunities to reveal cellular machinery and to enable molecule-based diagnosis (Science 2015(Science ... We show that there is constructive interference in the forward in forward direction, and destructive interference in backscattering direction. ...doi:10.15278/isms.2016.wb02 fatcat:oblsm3g4g5aqxjaz63feslacay
