Bentonite-loess slurry for construction of diaphragm walls and bored piles
Roads and Bridges, 2020 Bentonite fluids are used in narrow excavations in technologies of slurry walls and bored piles. If bentonite is characterised by high liquid limit, production of support fluid with sufficiently high density and accompanying low viscosity is impossible ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

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.

steel research international, EarlyView.H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...
