Interstratified Illite‐Hydroxy‐Interlayered Smectite—A Disorder Structure Model for Quantification Using Rietveld Refinement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The acidic weathering of soils is known as a problem for decades. It leads to the deterioration of essential soil properties, including soil fertility, water, or cation buffering capacity due to solution and solid storage of Al3+ by polymerization in the interlayer of (former) swellable clay minerals.

Stratigraphy and geomorphology of Des‐Cubierta Cave (Pinilla del Valle, Madrid, Spain): Geological insights into a Neanderthal symbolic accumulation of large crania

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Des‐Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years ...

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

open access: yesJournal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).

Polypept(o)ide‐Based Core–Shell Bottlebrush Polymers: A Versatile Platform for Drug Encapsulation

open access: yesMacromolecular Bioscience, EarlyView.
This study developed polypept(o)ide‐based core–shell brushes (CSBs) with tunable sizes (Rh: 17–70 nm) for hydrophobic drug delivery. CSBs achieved 10% dasatinib loading through π–π interactions, enabling sustained release over 72 h. Notably, CSB‐dasatinib complexes showed comparable cell viability reduction to the free drug in U‐87 MG cells ...
