Limnology and Oceanography: Methods, EarlyView.Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials
Small, EarlyView.In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

From mystery to modulation: the structural story of Rb2[Si2O5]
Acta Crystallographica Section B, EarlyView.The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial
Archaeometry, EarlyView.ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.
