Simple sensing device could make cleanup easier by identifying the type of oil involved in a spill. The device is designed to float on the water, where it could remotely monitor a small area susceptible to pollution or track the evolution of contamination at a particular location. “Fast detection of a spill is crucial for a quick antipollution response to avoid, as much as possible, the progressive mixture of the oil into the water, which would make cleaning more difficult and inefficient,” said Jose R...
