Redox-Controlled Ammonium Storage and Overturn in Ediacaran Oceans

open access: yesFrontiers in Earth Science, 2021
As a key nutrient, nitrogen can limit primary productivity and carbon cycle dynamics, but also evolutionary progress. Given strong redox-dependency of its molecular speciation, environmental conditions can control nitrogen localization and ...

Genetic Basis of Ammonium Toxicity Resistance in a Sake Strain of Yeast: A Mendelian Case. [PDF]

open access: yes, 2013
High concentrations of ammonium at physiological concentrations of potassium are toxic for the standard laboratory strain of Saccharomyces cerevisiae In the original description of this metabolic phenotype, we focused on the standard laboratory strains ...

Comparing Soil Nitrous Oxide and Methane Fluxes From Oil Palm Plantations and Adjacent Riparian Forests in Malaysian Borneo

open access: yesFrontiers in Forests and Global Change, 2021
Riparian forests are often kept as buffers between rivers and oil palm plantations. Many benefits of riparian forests, such as increasing biodiversity and providing a travel corridor for wildlife have been documented.

Synthesis and Properties of Acyclic Ammonium-based Ionic Liquids with Allyl Substituents as Electrolytes

open access: yesMolecules, 2009
Several new acyclic ammonium-TFSI ionic liquids with an allyl substituent(s) were synthesized and their physicochemical and electrochemical properties were characterized. [AAMM]Am-TFSI (3) with two allyl groups showed the widest electrochemical stability

Ammonium and methyl ammonium transport by RhAG

open access: yesThe FASEB Journal, 2012
The erythroid Rh protein (RhAG) is one component of the “Rh complex” that is known for its immunogenic characteristics. Recently, a role of RhAG in transport of ions has been proposed. In this study, we characterized NH3/NH4+ transport by RhAG expressed in Xenopus oocytes. To do so we used ion‐selective microelectrodes & two‐electrode voltage clamp

Amine exchange into ammonium bisulfate and ammonium nitrate nuclei [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Abstract. The exchange kinetics and thermodynamics of amines for ammonia in small (1–2 nm diameter) ammonium bisulfate and ammonium nitrate clusters were investigated using electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). Ammonium salt clusters were reacted with amine gas at constant pressure to determine
