Geosciences, 2017 Cr-spinels from ultramafic rocks from Lokris (Megaplatanos and Tragana), and Beotia (Ypato and Alyki) ophiolitic occurrences were studied. These rocks comprise principally harzburgite with minor dunite. Small amounts of clinopyroxene-rich harzburgite and

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration
Journal of Raman Spectroscopy, EarlyView.This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Small Science, EarlyView.The lithium supplementation strategy is employed to address the capacity loss in battery systems. This perspective focuses on various lithium compensation strategies in anode‐free lithium metal batteries (AFLMBs), emphasizing their mechanisms, compatibility, and lithium storage efficiency, and further provides insights for advancing the AFLMBs with ...

, 2011 Pulsation is believed to be the leading cause of dusty mass loss from Asymptotic Giant Branch (AGB) stars. We present a temporal study of T Cep, a long-period Mira variable, using seven ISO SWS spectra, covering a 16-month period over a single pulsation ...

Archaeometry, EarlyView.Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland
Boreas, EarlyView.Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 392-421, March 2025.Abstract The Calcalong Creek lunar meteorite is a regolith breccia with a lithologically diverse array of clasts set in a glassy, highly vesicular matrix. Here, we present a comprehensive new analysis of the meteorite. Comparisons to remote sensing data, lunar sample lithologies, and lunar sample ages indicate that it was likely sourced from regolith ...
