Spatial Variations in Vitreous Oxygen Consumption. [PDF]

open access: yesPLoS ONE, 2016
We investigated the spatial variation of vitreous oxygen consumption in enucleated porcine eyes. A custom made oxygen source was fabricated that could be localized to either the mid or posterior vitreous cavity and steady state vitreous oxygen tension ...

Baseline oxygen consumption decreases with cortical depth.

open access: yesPLoS Biology, 2022
The cerebral cortex is organized in cortical layers that differ in their cellular density, composition, and wiring. Cortical laminar architecture is also readily revealed by staining for cytochrome oxidase-the last enzyme in the respiratory electron ...

Energy Consumption Optimization of a Synthetic Ammonia Process Based on Oxygen Purity

open access: yesChemical Engineering Transactions, 2018
The energy consumption of an ammonia process is huge, and it occupies a large proportion in the industrial energy consumption. The air separation unit is an important energy-consuming unit in the process of ammonia synthesis. For the ammonia process with

Substantial oxygen consumption by aerobic nitrite oxidation in oceanic oxygen minimum zones

open access: yesNature Communications, 2021
Oxygen is fundamental for marine life, yet it is absent from large areas of the ocean. Here the authors demonstrate that microbial nitrite oxidation effectively consumes oxygen where oxygen concentrations are low, playing a pivotal role in these regions.
