The researchers directed a precisely tuned 225.7 nm femtosecond laser into water enriched with atomic oxygen generated by a ...

They observe for the first time the movement of oxygen atoms in liquid water, revealing life forms and effects for plasma ...

Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years.

TALIF works by using a precisely tuned laser to excite the atoms being measured. Instead of absorbing a single photon, each atom absorbs two photons at the same time, and the combined energy of these ...

For roughly 2 billion years of Earth's early history, the atmosphere contained no oxygen, the essential ingredient required ...

Endress+Hauser's Memosens COS81D hygienic optical sensor can measure dissolved oxygen in pharmaceutical fermenters and bioreactors. Endress+Hauser’s Memosens COS81D hygienic optical sensor can measure ...

These nodules can act like batteries that split seawater into hydrogen and oxygen In an unexpected twist, metal-rich nodules found on the seafloor are generating oxygen, new research suggests. This ...

Efforts to reduce nitrogen pollution in the Sound, include wetlands restoration, upgraded septic systems, stormwater ...

Experienced boiler operators know that oxygen can cause localized, severe corrosion in steam boiler systems through a process called oxygen pitting. This occurs when dissolved oxygen in the water ...

Dissolved oxygen meters are used to quantify the amount of dissolved oxygen (DO) in surface waters or at different stages of wastewater treatment. There are two dissolved oxygen meters in the ...
