Spectral analysis of lunar regions observed by MAJIS during the JUICE Moon-Earth flyby

Abstract. The Moons and Jupiter Imaging Spectrometer (MAJIS) instrument onboard the ESA Jupiter Icy Moon Explorer (JUICE) mission acquired the first hyperspectral data of the lunar surface since Chandrayaan-1/Moon Mineralogy Mapper (M3), Cassini/VIMS, and the more recent Chandray...

Whole‐crop harvestable chicory for the phytoextraction of copper from wine‐growing soils and its use in animal feed

Abstract Background Since 2018, European Union regulations have reduced copper (Cu) doses in viticulture to combat fungal diseases, but Cu continues to accumulate in soils, potentially harming soil organisms. The aim of our study was to reduce the Cu content of soils by means of...

Intra- and inter-specific variability in benthic foraminifera modulates surface sediment reworking

Abstract Bioturbation is a key ecological process that regulates benthic ecosystem functioning, including organic matter remineralization and nutrient regeneration. Despite growing evidence that meiofauna, and benthic foraminifera in particular, contribute to sediment bioturbatio...

Structural Responses of Aluminoborosilicate Glasses to Pressure and Iodine Incorporation: An Advanced NMR Investigation

ABSTRACT Iodine‐129 is a critical challenge for nuclear waste immobilization due to its high mobility and extremely long half‐life (1.57 × 10 7 years). Although high‐pressure glass synthesis has been shown to significantly enhance iodine solubility, the structural mechanisms gove...

Post launch spectral and radiometric performances of MAJIS, the VIS-NIR imaging spectrometer of JUICE

Abstract. The post-launch spectral and radiometric performances of MAJIS, the VISNIR imaging spectrometer of the ESA Jupiter Icy Moon Explorer (JUICE), have been evaluated using observations performed during the Lunar-Earth Gravitational Assist (LEGA) of 19–20 August 2024 and obs...
