To further improve combustion efficiency and save energy, measurement of the oxygen concentration in exhaust gases is required. (yokogawa.com)
The measurement of oxygen concentration in the furnace is essential. (yokogawa.com)

Chemical oxygen generators are not used for the cockpit crew, who are typically supplied using compressed oxygen canisters, also known as oxygen bottles. (wikipedia.org)

As dependence on iron is a key feature of tumor cells, using chelators to reduce iron represents an opportunity to improve conventional GBM therapies. (biomedcentral.com)
Taken together, these in vitro results could raise the question of the benefit of using iron chelators in their native forms under the hypoxic conditions often encountered in solid tumors such as GBM. (biomedcentral.com)
Therefore, fungi evolved fine-tuned mechanisms for uptake and storage of iron, such as the production of siderophores (low-molecular mass iron-specific chelators). (frontiersin.org)

TMPRSS6 gene mutations reduce or eliminate functional matriptase-2, which disrupts iron regulation and leads to a shortage of iron in the bloodstream. (medlineplus.gov)

Premium oxygen free copper (OFC). (ironforgetools.com)
The geological framework and origin of the iron-copper-cobalt-gold-rare earth element (IOCG-REE) deposits in southeast Missouri are not well defined. (usgs.gov)
This terrane is geologically analogous to iron-copper-gold-rare earth element-uranium deposit and similar (but smaller) deposits that have been discovered there in recent years. (usgs.gov)

[ 10 ] It is this excessive iron that damages tissues. (medscape.com)
With further development, the findings could inform a potential treatment that lowers oxygen levels in certain tissues in humans to reverse advanced disease. (broadinstitute.org)

On the International Space Station, chemical oxygen generators are used as a backup supply. (wikipedia.org)
This new finding, which was made using W. M. Keck Observatory on Maunakea in Hawaii to analyze the chemical makeup of the ancient star, provides an important clue on how oxygen and other important elements were produced in the first generations of stars in the universe. (sciencedaily.com)
The data, which required more than five hours of staring at the star over a single night, were used to measure the abundances of 16 chemical species in the star's atmosphere, including oxygen. (sciencedaily.com)
Syngas production from chemical looping reforming of ethanol over iron-based oxygen carriers: Theoretical analysis and experimental investigation[J]. Chinese Journal of Chemical Engineering, 2021, 38(10): 123-131. (cip.com.cn)
This finding, reported in the journal The Astrophysical Journal Letters today, provides an important clue on how oxygen and other chemical elements were produced in the first generations of stars in the Universe. (iac.es)

Thermal decomposition releases the oxygen. (wikipedia.org)
FeO can be prepared by the thermal decomposition of iron(II) oxalate . (wikipedia.org)

A furnaces for heating slabs needs to be operated under low-oxygen conditions at high temperatures of 1000°C and above to prevent oxidation of the steel. (yokogawa.com)

All of the virulence-associated genes are transcriptionally upregulated during iron starvation and encode functions that are important for survival during iron starvation, which emphasizes the crucial role of adaptation to iron starvation in virulence. (frontiersin.org)
