Photochemical

Indicative of the importance of different chemicals interacting to cause smog, is the term photochemical smog. ❋ Unknown (2009)

Because this type of smog forms when chemical reactions take place in the presence of sunlight, it is termed photochemical smog. ❋ Unknown (2008)

Puralytics, winner of this year's CleanTech Open, uses photochemical processes work to break down or remove contaminants from water. ❋ Andrew Winston (2011)

On Earth, methane produced by bogs or cows can remain for a decade; on Mars, for reasons that are not fully understood but imply a photochemical destruction process unlike anything now known, the gas is destroyed in under a year. ❋ Marc Kaufman (2011)

Her research focuses on the poryphyrins, which can be used as photosensitive drugs for cancer treatment, photosensitizers for photochemical destruction of pollutants in water, and in the development of sensors for biologically and medically important molecules. ❋ Peggy (2008)

Ozone is an important tracer of photochemical processes in the atmosphere of Mars. ❋ Unknown (2010)

Mixed with pollution from the growing number of heavy industries in northern China, the particles create photochemical smogs in Korea, Japan, and toxic winds that blow across the Pacific to the west coast of the United States, adding the problem of “global dimming” to that of global warming.5 ❋ Jonathan Watts (2010)

The team also performed measurements of the ozone abundance over the Syrtis Major region, which will help to constrain photochemical models in this region. ❋ Unknown (2010)

Likewise, chemical energy could also have provided initial energy; with a switch to other forms photochemical, etc coming later. ❋ Unknown (2010)

Putting the compatibility of the data from these two instruments on a firm base will support combining the ground-based infrared measurements with the SPICAM ultraviolet measurements in testing the photochemical models of the Martian atmosphere. ❋ Unknown (2010)

Although not explicit in the Physics Reports paper, Lu explicitly relies on the aforementhions Pope ClOOCl absorption cross-section which would limit the amount of ClO in the atmosphere, as a falsification of the photochemical models, but that result is, as they say, in deep doo doo, gone histoire..... some more to report soon ❋ EliRabett (2010)

To test predictions by current models of photochemical processes and general atmospheric circulation patterns, observations of spatial and temporal ozone variations are required. ❋ Unknown (2010)

The second source of water vapor is the photochemical decomposition of methane in the stratosphere which only comes into play at high altitudes, explaining the increasing concentration of water vapor at the left of Figure 1. ❋ EliRabett (2010)
