No limit? The multiphasic uptake of silicic acid by benthic diatoms
No limit multiphasic uptake silicic acid benthic diatoms
2014/4/18
Silicic-acid uptake kinetics for a field population of benthic diatoms were examined using a radioisotope tracer over a concentration range of 0–300mmol L21. The microphytobenthos half saturation cons...
Control of silica production by iron and silicic acid during the Southern Ocean Iron Experiment (SOFeX)
silica production iron and silicic acid Southern Ocean Iron Experiment
2014/5/9
We examined the role of Si limitation in mediating the response of siliceous biomass and silica production to mesoscale Fe fertilization in the high-silicic acid high-nitrate waters of the Antarctic a...
Comparison of size-dependent carbon, nitrate, and silicic acid uptake rates in high- and low-iron waters
size-dependent carbon nitrate silicic acid uptake rates high- and low-iron waters
2014/5/9
We compare the relative contribution of large phytoplankton (>5 and >10 μm) to uptake rates of carbon (C), nitrate (NO3-), and dissolved silicon (Si) and uptake ratios of Si :NO and Si :C in Monterey ...
Effect of iron deficiency on diatom cell size and silicic acid uptake kinetics
iron deficiency diatom cell size silicic acid uptake kinetics
2014/5/19
We studied the silicic acid uptake kinetics of the pennate diatom Cylindrotheca fusiformis grown under a wide range of iron concentrations (from Fe-limiting to Fe-sufficient conditions) to assess the ...
Effects of ultraviolet-B radiation and vertical mixing on nitrogen uptake by a natural planktonic community shifting from nitrate to silicic acid deficiency
ltraviolet-B radiation vertical mixing
2014/5/20
We investigated the combined effects of mixing regimes and ultraviolet-B radiation (UVBR: 280–320 nm) on
the uptake of nitrate, ammonium, and urea by an estuarine phytoplankton community during a 10-...
Tris(Acetylacetonato)Silicon(IV) Binding to Montmorillonite and Hydrolysis to Interlayer Silicic Acid
Hydrolysis Montmorillonite Pillared interlayer complex Si(acac)3+ Silicic acid
2012/2/2
The reactions of the tris(acetylacetonato)silicone(IV) cation (Si(acac)3+) with Na+-, Mg2+-, and Co2+-exchange forms of hectorite and montmorillonite have been investigated to understand better the fo...
