Moessbauer spectrometry

Abstract

played in chemical analysis by microwave spectroscopy remains to be determined. To this end, it is important that those in the business of chemical analysis become sufficiently familiar with the technique to recognize when microwave spectroscopy can be applied profitably to their problems.

Heteronuclear dual-metal atom catalysts for nanocatalytic tumor therapy

“…(2) Only finite types of nuclei such as Fe and Sn have the Mössbauer effect, and must be carried out at low temperatures or in laboratories with preparation source conditions, which limits its application. [141][142][143][144][145] energy to match the internal electron shell of the target element, and then collect the absorbed X-ray amount and discuss its energy dependence [117,118]. It can help researchers to identify the dynamic structure/bond state evolution of reaction centers under working conditions.…”

Alternative Reductants for Foam Control During Vitrification of High-Iron High Level Waste (Hlw) Feeds

“…The CS values of these sites are all within the range of tetrahedral Fe 3+ [54] each sample has a site with relatively lower and higher QS, indicating a site where the electron cloud symmetry is distorted by local bonding, e.g. rather than Fe-O-Fe there are Fe-O-M bonds where M is an atom with a different electronegativity [59]. In the HLW-NG-Fe2-S sample at 1000 ℃ there is a IV Fe 2+ phase contributing 2.4 ± 2% to the spectral area, which is only slightly above error.…”

Moessbauer spectrometry

“…It is based on subjectively weighted averages of many experiments over a large time interval. As in the previous review (726), we give most of the information on chemical applications of Móssbauer spectrometry during 1972-73 in the following tables, dealing with 57Fe (Table II), 119Sn (Table III) and other isotopes (Table IV).…”
