Oxygen diffusion in soils: Understanding the factors and processes needed for modeling
(Inst Investigaciones Agropecuarias, 2015)
Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...
Oxygen integration of autothermal reforming of ethanol with oxygen production, through ion transport membranes in countercurrent configuration
(Pergamon-Elsevier Science Ltd, 2017-04)
In this work, we propose a new arrangement for integrating an Autothermal Reforming of Ethanol process with oxygen production with the technology of ITM membranes. In the conventional configuration O2is first separated ...
Modeling the influence of benthic primary production on oxygen transport through the water-sediment interface
The context of this study is salty lagoons a few centimeters deep that are found in the arid region of the Andes Mountains in South America. The trophic structure of these aquatic ecosystems is supported by microalgae and ...
Blood oxygen affinity increases during digestion in the South American rattlesnake, Crotalus durissus terrificus
(Elsevier B. V., 2015)
Digesting snakes experience massive increases in metabolism that can last for many days and are accompanied by adjustments in the oxygen transport cascade. Accordingly, we examined the oxygen-binding properties of the blood ...
Determination of Electrode Oxygen Transport Kinetics Using Electrochemical Impedance Spectroscopy Combined with Three-Dimensional Microstructure Measurement: Application to Nd2NiO4+δ
(Electrochemical Society, 2014-10)
Oxygen reduction kinetic parameters – oxygen ion diffusion Dδ, molar surface exchange rate ℜO and surface exchange coefficient k – were determined for porous Nd2NiO4+δ solid oxide fuel cell cathodes as a function of ...
