Looking at oxygen storage dynamics in three-way catalysts

In light of vehicular pollutants contributing to decreasing air quality, governments across the globe are posing stricter emission regulations for automobiles. This calls for the development of more efficient exhaust gas ...

Describing the mechanism by which oxygen in the blood is detected

Hypoxia (oxygen deficiency), in addition to occurring in areas of considerable altitude, is a critical factor linked to various cardiopulmonary diseases of high morbidity and mortality in humans. The carotid body, a highly ...

How gas nanobubbles accelerate solid-liquid-gas reactions

Solid-liquid-gas reactions are common in various natural phenomenon and industrial applications, such as hydrogen-oxygen fuel cell reactions, heterogeneous catalysis and metal corrosion in ambient environments. However, the ...

Defects in quartz crystal structure reveal the origin of dust

Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, ...

How some tissues can 'breathe' without oxygen

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

How plants prevent oxidative stress

When excess light energy is absorbed by plants during photosynthesis, harmful reactive oxygen species are produced. These reactive oxygen species break down important structures such as proteins and membranes, preventing ...
