Recent studies of sediment capping and flocculation for nutrient stabilisation [PDF]
, 2006 Water quality in the Rotorua Lakes has declined in the past 30 to 40 years due to increasing nutrient loads, specifically nitrogen and phosphorus. In situ restoration techniques, including sediment capping and flocculation, have been developed to attempt

Advanced Science, EarlyView.Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude

Simulating complex hydro-geomorphic changes in lake-catchment systems [PDF]
, 2013 Management of lake-catchment systems is a long-term challenge for prevention of hazard risk and further sustainable development. Climate change and human activities are two important factors that concurrently affect the hydrology and sediment regimes ...

Phosphorus fractions and alkaline phosphatase activity in sediments of a large eutrophic Chinese lake (Lake Taihu) [PDF]
, 2008 Spatial, vertical, and seasonal variations in phosphorus fractions and in alkaline phosphatase activity (APA) were investigated in sediments in a large-shallow eutrophic Chinese lake (Lake Taihu) in 2003-2004.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Modeling and interpreting element ratios in water and sediments: A sensitivity analysis of post-Chernobyl Ru : Cs ratios. [PDF]
, 1995 When elements are simultaneously added to lakes, experimentally or by accident, their ratios in the water phase and in bottom sediments can change with time due to differential partitioning between solution and suspended particles or sediments.
