P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
Terra Nova, Volume 38, Issue 1, Page 65-76, February 2026.ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Pressure-induced phase transitions in AgClO4 [PDF]
, 2011 AgClO4 has been studied under compression by x-ray diffraction and density functional theory calculations. Experimental evidence of a structural phase transition from the tetragonal structure of AgClO4 to an orthorhombic barite-type structure has been ...

ChemBioChem, Volume 27, Issue 1, January 2026.The synthesis and the investigation of the lanthanide (Ln) and Fe‐binding properties of the putative lanthanophore methylolanthanin (MLL) and the siderophore rhodopetrobactin B (RPB B) are reported. While both chelators bind Lns, they unexpectedly precipitate with Lns under biologically relevant conditions and thereby challenge the proposed classic ...
