The emission ((57)Co) variant of Mössbauer spectroscopy, rarely used in biology-related studies, was applied to study binding and possible transformations of (57)Co(II) traces in live and dead (hydrothermally treated) cells of the rhizobacterium Azospirillum brasilense (strain Sp7) at T=80 K in frozen aqueous suspensions and as their dried residues. The Mössbauer parameters calculated from the ...

The stability of iron ascorbate solutions was investigated, under both anaerobic and aerobic conditions, with the Fe2+ and Fe3+ indicators, respectively ferrozine and mimosine, at different pH values. The species present under the differing conditions were investigated by electron paramagnetic resonance (EPR) and Mössbauer spectroscopy and by gel-filtration chromatography. At physiological pH (...

Herein is presented a review of recent technical advances in Raman and nuclear resonance spectroscopy (both Mössbauer spectroscopy and nuclear resonant inelastic Xray scattering spectroscopy (NRIXS)), as they have great implications for geoscience. Optical and X-ray spectroscopies probe different momentum and energy transfers caused by interactions between the incident light and the lattice, ma...

1. Introduction Recently a method based on the emission Mössbauer spectroscopy of radioisotope nuclei inserted in grain boundaries worked out by Klotsman and Kaigorodov [1] was successfully employed in a number of studies of grain boundaries in transition and noble metals. In the present investigation this method is used to study the diffusion mechanism and grain boundary segregation in polycry...
