Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

In this study, we revealed the disturbed metabolic status of circulating and tumour‐infiltrating CD4+ and CD8+ T cells in melanoma patients through targeted metabolomic and lipidomic (on sorted subsets) and at single cell level using the SCENITH method.

ABSTRACT The extensive use of glyphosate for weed control in‐crop poses significant risks to non‐target crops, such as wheat, due to spray drift. Biostimulants are widely used to improve nutrient uptake, stimulate root growth, and enhance tolerance to abiotic stress. These growth effects of biostimulants may aid in alleviating glyphosate‐induced damage

Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.
