Fish and other aquatic organisms survive in water because of DO. The amount of DO in water is affected by the water temperature, salt concentration, and atmospheric pressure, among other factors.

The absorption of light by organic molecules with chromophores contribute to the formation of brown carbon in the atmosphere, which can partially counteract the expected cooling effect of aerosols on ...

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 ...

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 ...

Modern-day Mars may be more hospitable to oxygen-breathing life than previously thought. A new study suggests that salty water at or near the surface of the red planet could contain enough dissolved ...

Scientists have directly imaged atomic oxygen in water using a femtosecond laser, revealing unexpected stability and movement in liquids.

Salty water buried just beneath the Martian surface could have enough dissolved oxygen to support microbes, and perhaps even simple animal life such as sponges in some places, a new study suggests.

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 ...
