Mössbauer spectroscopy in inorganic glasses
TLDR
In this paper, the Mossbauer effect has been used in the study of nuclear gamma ray absorption in crystalline systems, and the theory of the effect and its practical details are presented.Abstract:
Recoil-free emission and resonant absorption of nuclear gamma rays (i.e., the Mossbauer effect) has proven to be an effective tool in the study of certain physical and chemical properties of crystalline systems. The theory of the effect, as well as certain practical details, are presented. On this basis the experimental work on inorganic glasses is discussed and the usefulness of the tool in such systems assessed.read more

Investigation of the high-temperature behaviour of coal ash in reducing and oxidizing atmospheres
TL;DR: In this paper, phase analysis of ash samples quenched from various temperatures under either a reducing (60% CO/40% CO2) or an oxidizing (air) atmosphere was performed by Mossbauer spectroscopy, scanning electron microscopy (SEM)/automatic image analysis (AIA), and X-ray diffraction (XRD).

Structure and redox equilibria of iron-bearing silicate melts
TL;DR: In this article, the anionic structure of the silicate network of the melts has been determined with laser Raman spectroscopy, and it was interpreted to suggest that quenched metasilicate melts on the join CaSiO3-MgSiO 3 predominantly consist of three structural unitsseparate Sioxtetrahedra, Siroland Sirofunits.

Interpretation of the Fe 57 Isomer Shift
TL;DR: In this article, the Hartree-Fock calculations of Watson on the various 3D configurstions of iron were combined with the data on the isomeric shifts in the most ionic compounds to calibrate the shift in terms of s-electron density.

Note on the Paramagnetic Resonance of Iron in Glass
TL;DR: In this article, a theory is proposed explaining the observed g value and the implications for the atomic surroundings of Fe++ + + are discussed, and it is also proposed that the g=6 resonance observed in glass by Sands is due to Fe+ ++ + plus.
