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 ...

Trade winds ventilate the tropical oceans

Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and ...

Better oxygen extraction attracts commercial interest

Developing highly efficient ion transport membranes for the extraction of oxygen for industrial and medical use has earned a team of Curtin University scientists first prize in the university's Commercial Innovation Awards.
