Construction and characterisation of the DarkSide-20k veto silicon photo-multiplier tiles
Abstract Silicon photo-multipliers (SiPMs) are state-of-the-art sensors capable of detecting a single photoelectron under cryogenic conditions, with potentially lower radioactivity than widely used photomultiplier tubes. The DarkSide-20k experiment, designed to perform direct dar...

Design Principles of Optimizing Cementitious Glasses for the Disposal of Radioactive Waste
ABSTRACT We designed, synthesized, and characterized 26 cementitious calcium‐magnesium aluminosilicate (CMAS) glasses using the chemical and mineralogical properties of ordinary Portland cement (OPC), ground, granulated blast furnace slag (BFS), and class F fly ash as bounding co...

Microbial decomposition of organic matter in a constructed wetland designed for metal retention
Abstract Metal contaminants threaten water resources and constructed wetlands can retain them using microbial processes that are supported by organic compounds. However, organic compounds also form transient metal complexes. To determine how microbial communities from a construct...

ABSTRACT High‐valent oxyanions, such as chromate (Cr VI O 4 2− ) and pertechnetate ( 99 Tc VII O 4 − ), are highly soluble, weakly coordinating, and exceptionally stable, making their removal from water and nuclear waste extremely challenging. Here, we report a redox‐coupled meta...
