Sentences with phrase «oxygen gas bubbles»

Not exact matches

Many of us are familiar with electrolytic splitting of water from their school days: if you hold two electrodes into an aqueous electrolyte and apply a sufficient voltage, gas bubbles of hydrogen and oxygen are formed.

Now a report in the 26 January Physical Review Letters suggests that searing hot temperatures generated inside the bubbles drive out nitrogen and oxygen, leaving behind a stunning light show produced by the trace gas argon.

«Without a membrane, the photoanode and photocathode are close enough to each other to conduct electricity, and if you also have bubbles of highly reactive hydrogen and oxygen gases being produced in the same place at the same time, that is a recipe for disaster,» Lewis says.

When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.

«Without a membrane, the photoanode and photocathode are close enough to each other to conduct electricity, and if you also have bubbles of highly reactive hydrogen and oxygen gases being produced in the same place at the same time, that is a recipe for disaster,» Lewis says regarding his findings published in PNAS.

The physiologic effects of Hyperbaric Oxygen Therapy («HBOT») include improved oxygenation, intravascular and tissue gas bubble reduction, vasoconstriction, increased antimicrobial activity, modulation of inflammation, improved immune function, and angiogenesis.

For example, ice cores taken in various locations around the world (Greenland and Antarctica, for example) are excellent proxies; gas bubbles containing CO2 trapped in ancient ice can be measured, and the age can be determined very accurately (by counting the seasonal ice layers, or measuring the isotope levels of oxygen).
