Changes in phosphorus biogeochemistry along an estuarine salinity gradient: The iron conveyer belt
Changes in phosphorus biogeochemistry estuarine salinity gradient The iron conveyer belt
2014/4/18
We used sequential extractions to quantify different forms of particulate phosphorus (PP) in sediments along the salinity gradient of the Patuxent River estuary. About 50-90% of the PP was phosphate b...
Effects of Clay Fraction and Temperature on the H2O Self-Diffusivity in Hectorite Gel: A Pulsed-Field-Gradient Spin-Echo Nuclear Magnetic Resonance Study
Complexity of Pore Structure Hectorite H2O NMR Self-Diffusion
2011/12/6
Abstract: Self-diffusion coefficients of H2O molecules in Na-rich hectorite gel were measured by 1H nuclear magnetic resonance (NMR). Spin-echo pulse sequences with magnetic field gradient pulses for ...
