Hyperfine Interactions and Metal Atom Dynamics in a Number of Stannyl Phosphide Compounds and the Detailed Crystal Structure of Triphenyltin Chloride Revisited
Autor: Rolfe H. Herber, Benny Bogoslavsky, Israel Nowik
Publikováno v: European Journal of Inorganic Chemistry. 2016:1619-1624
Temperature-dependent 119Sn Mossbauer effect (ME) spectroscopy has been used to elucidate the hyperfine parameters (isomer shift and quadrupole splitting) as well as the dynamics of the motion of tin in three triphenyltin phosphide complexes, namely

Publikováno v: Journal of synchrotron radiation. 26(Pt 2)
Three experiments are reviewed, performed (in 2014–2016) at ID18 of ESRF to measure the influence of acceleration on time dilation by measuring the relative shift between the absorption lines of two states of the same rotating absorber with acceler

Publikováno v: Journal of Synchrotron Radiation. 22:723-728
Many Mössbauer spectroscopy (MS) experiments have used a rotating absorber in order to measure the second-order transverse Doppler (TD) shift, and to test the validity of the Einstein time dilation theory. From these experiments, one may also test t

Publikováno v: Journal of Materials Chemistry C. 3:10723-10727
We report the development of new conductive–magnetic composite films obtained by the entrapment of silver nanowires (AgNWs) in sol–gel derived magnetite. The resulting films are highly adhesive on PET, highly flexible, and translucent. The films
