Cooling molecules Earth

Scientists have long predicted the existence of molecular cooling the Earth. The presence of molecules that ultimately proved successful. Molecule called Criegee biradikal.

Researchers from the University of Manchester, University of Bristol and Sandia National Laboratories is able to prove its existence. They say that the Criegee biradikal is able to oxidize pollutants such as nitrogen dioxide and sulfur dioxide from combustion.

The presence of these molecules was detected using the light from the third generation synchroton facility at the Advanced Light Source at Lawrence Berkeley National Laboratory.

The intense light and can be adjusted from synchroton it allows scientists to distinguish different types of isomers, molecules consisting of the same atoms but have different arrangements.

Based on research, biradikan Criegee pollutants react more quickly than expected. These molecules accelerate the formation of aerosols in the atmosphere spur and cloud formation. This enables these molecules to function as a cooling planet.

"We have been able to support how fast biradikal Criegee reaction for the first time. Hail is a significant impact on our understanding of atmospheric oxidation capacity and the broad implications on pollution and climate change," said Carl Percival, an expert from the University of Machester, told TG Daily , Monday (16/01/2012).

"Sources biradikal Criegee not depend on sunlight, so the process can occur on the day and night," added Percival.

And now this molecule may also have a role to protect our planet.

"The materials needed for production biradikal Criegee derived from a chemical compound that is released naturally by plants, so the ecosystem is significantly contribute to preventing warming," said Sudley Shallcross from the University of Bristol.

If the hopes that this molecule could clear the forest of human wishes and prevent climate change by cooling molecules, it seems it can not be done.
