The optical probe measures the interaction between dissolved oxygen and luminescent dyes within the probe. As oxygen molecules pass through the semipermeable membrane, blue light excites the oxygen ...

Oxygen is crucial for aquatic life to thrive. But levels of dissolved oxygen have declined in many watery environments, ...

The oxygen atom has a stronger pull on electrons than the carbon atom. This makes the oxygen ends of the molecule slightly negative and the carbon atom slightly positive. Although the candies seem ...
