A phenomenological model is exploited to obtain the thermomagnetic parameters. The magnon drag and phonon drag largely decide the thermoelectric power in the low-temperature ferromagnetic region, whereas the small polaron hopping of carriers contributes to the TEP in the high-temperature paramagnetic region. A colossal TEP value of -800 μV K-1 is observed at around 14 K for the x = 0.3 sample.A trimeric tri-Tb3+-including antimonotungstate (AMT) hybrid Na17(WO4)[Tb(H2O)(Ac)(B-α-SbW9O31(OH)2)]3·50H2O (Tb3W28) was successfully s

In European rivers, research and monitoring programmes have targeted metal pollution from bed and floodplain sediments since the mid-20th century by using various sampling and analysis protocols. We propose to characterise metal contamination trajectories since the 1960s based on the joint use of a large amount of data from dated cores and subsurface sediments along the Rhône River (ca. 512 km, Switzerland-France). For the reconstruction of spatio-temporal trends, enrichment factors (EF) and geo-accumulation (Igeo) approaches were compared. The latter index
