Contribution à l'étude du système ternaire H2O-(NH4)3Al(C2O4)3-(NH4)2MO2O5(C2O4)2. L'isotherme 25 °C

, 2001
The H2O-(NH4)2Mo2O5(C2O4)2 binary system has been investigated in the -20 to 75°C temperature range. An incongruently melting dihydrate is observed. The solubility curves at 25°C for H2O-(NH4)3Al(C2O4)3-(NH4)2Mo2O5(C2O4)2 system have been established ...

Soil Inorganic Electron Acceptors and Carbon Substrates Hierarchically Govern Wetland Methanogenesis Temperature Response

Advanced Science, EarlyView.
ABSTRACT Wetlands constitute Earth's largest natural methane (CH4) source, yet projections of their climate feedback remain uncertain due to poorly constrained temperature sensitivity (Q10‐CH4) of microbial methanogenesis. While water table dynamics have been demonstrated to regulate wetland methanogenesis by altering key soil conditions such as ...

Feedback inhibition of AMT1 NH4 +-transporters mediated by CIPK15 kinase

BMC Biology, 2020
Background Ammonium (NH4 +), a key nitrogen form, becomes toxic when it accumulates to high levels. Ammonium transporters (AMTs) are the key transporters responsible for NH4 + uptake.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...

Growth, physiology, and metabolism of Halomonas meridiana in aqueous ammonium sulfate with implications for icy moon astrobiology

Frontiers in Microbiology
The discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan. Tentative evidence of ammonium sulfate ((NH4)2SO4) has been detected on the surface of Europa, and (NH4)2SO4 could be a prominent ...
