Article Synopsis
- - The crystal structure of samarium iron borate was studied, revealing that about 7% of Bi atoms were included when grown with BiMoO flux, while LiWO flux resulted in pure crystals without impurities.
- - Below 80 K, the (SmBi)Fe(BO) structure exhibited a negative thermal expansion, and its properties were characterized by various atomic distance changes as temperature decreased, with specific behavior noted for different atoms.
- - The study determined the Néel temperature to be 31.93 K, indicating a transition to easy-plane long-range magnetic ordering, with findings supported by paramagnetic Mössbauer spectra showing linear changes with cooling.
Bioerosion is a process with a high socio-economic impact that contributes to coastal retreat, and likely to increase with climate change. Whereas limestone bioerosion is well explained by a combination of mechanical and chemical pathways, the bioerosion mechanisms of silicates, which are harder and chemically more resistant, remain elusive. Here we investigated the interface between siltstone and freshwater rock-boring bivalves Lignopholas fluminalis (Bivalvia: Pholadidae).
