Hypoxia activates a Ca2+-permeable cation conductance sensitive to carbon monoxide and to GsMTx-4 in human and mouse sickle erythrocytes. [PDF]

open access: yesPLoS ONE, 2010
Deoxygenation of sickle erythrocytes activates a cation permeability of unknown molecular identity (Psickle), leading to elevated intracellular [Ca(2+)] ([Ca(2+)](i)) and subsequent activation of K(Ca) 3.1.

Microbial Respiration, the Engine of Ocean Deoxygenation [PDF]

open access: yesFrontiers in Marine Science, 2019
Microbial plankton respiration is the key determinant in the balance between the storage of organic carbon in the oceans or its conversion to carbon dioxide with accompanying consumption of dissolved oxygen.

The influence of deoxygenation on Caribbean coral larval settlement and early survival

open access: yesFrontiers in Marine Science, 2023
Deoxygenation is emerging as a major threat to coral reefs where it can have catastrophic effects, including mass coral mortality. Some coral species cannot survive more than a few days of exposure to low oxygen conditions, while others can tolerate ...

Comparative, reusability and regeneration study of potassium oxide-based catalyst in deoxygenation reaction of WCO

open access: yesEnergy Conversion and Management: X, 2022
In this work, the comparative study on the performance of K2O/SiO2 and calcined dolomite catalysts was conducted via deoxygenation of waste cooking oil (WCO). KSi catalyst has the potential as a deoxygenation catalyst due to mesoporous structure catalyst

Differential susceptibility of reef-building corals to deoxygenation reveals remarkable hypoxia tolerance

open access: yesScientific Reports, 2021
Ocean deoxygenation threatens the persistence of coastal ecosystems worldwide. Despite an increasing awareness that coastal deoxygenation impacts tropical habitats, there remains a paucity of empirical data on the effects of oxygen limitation on reef ...

Investigation on in-situ deoxygenation performance of bio-oil model compound guaiacol over Ce-Fe/Al2O3 catalyst

open access: yesGreen Energy and Resources, 2023
The investigation of the low-cost deoxygenation of guaiacol (GUA, a model bio-oil compound) is of importance for upgrading bio-oil. At present, common sulfide catalysts for GUA deoxygenation reactions cause contamination of the liquid product, and noble ...

Hydrogen-free Deoxygenation of Waste Cooking Oil over Unreduced Bimetallic NiCo Catalysts for Biojet Fuel Production

open access: yesChemical Engineering Transactions, 2023
The conversion of waste cooking oil (WCO) into renewable fuels has been proposed as a waste utilisation method which can ease global energy demand. The deoxygenation of WCO into fuel range hydrocarbons avoids the use of expensive hydrogen but comes at ...
