The sequestration of phosphate by iron phases in the sediments from Lake Rotorua, New Zealand
, 2007 A sequential extraction method was used to determine which dominant sedimentary mineral phase was involved in phosphorus retention in the sediments of Lake Rotorua and to verify the importance of iron phases in the role as a phosphorus sink. The observed

The mineralogy, geochemistry, and petrogenesis of the grønnedal-íka alkaline igneous complex, south-west Greenland [PDF]
, 1989 At 1299±17 Ma (Blaxland et al, 1978), the Grønnedal-Íka is the oldest of the Gardar centres, situated in the extreme north-west of the province. Hare-earth clement (REE) trends suggest that the nepheline-syenites which make up the bulk of the complex ...

Advanced Science, EarlyView.This study presents a ″trash‐to‐treasure″ strategy that converts harmful joint overloads into beneficial electrical cues. The biodegradable MagPie, by providing piezoelectrical stimulation and releasing Mg2+ during mastication, exerts synergistic pro‐regenerative and anti‐inflammatory effects on Prg4+ cells via the ECM‐mediated FAK‐PI3K‐Akt axis ...

Advanced Science, EarlyView.Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework
