Vehicles running on ethanol will generate higher concentrations of ozone than those using gasoline, especially in the winter, Stanford researchers have found. That could create new health concerns in areas where ozone hasn't been a significant problem before.

 | Purdue University ice chemists are studying the surface structure of snow crystals and why sharp transitions in shape occur at different temperatures. The differences they see not only explain why no two snowflakes are identical, but also hold implications for their ozone research in the Arctic Ocean region. ...> Full Article |
 | Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. ...> Full Article |
 | Chemists have discovered that a chemical reaction in the atmosphere above major cities long assumed to be unimportant in urban air pollution is in fact a significant contributor to urban ozone-the main component of smog. ...> Full Article |
 | Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere. This is the result of climate simulations, which have just been published in the journal „Geophysical Research Letters" (Brand et al, Geophys. Res. Lett.). Scientists at the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research, which is a member of the Helmholtz Association, have investigated a fundamental process for climate interactions in the Arctic. So far it is not known what causes natural variations of atmospheric air flow patterns which have been playing an important role for climate changes in the last decades. This basic knowledge is necessary to improve climate models that still hold much uncertainty. ...> Full Article |
