Molecular Storage of Ozone in a Clathrate Hydrate: An Attempt at Preserving Ozone at High Concentrations
This paper reports an experimental study of the formation of a mixed O(3)+ O(2)+ CO(2) hydrate and its frozen storage under atmospheric pressure, which aimed to establish a hydrate-based technology for preserving ozone (O(3)), a chemically unstable substance, for various industrial, medical and consumer uses. By improving the experimental technique that we recently devised for forming an O(3)+ ...

متن کاملStratospheric ozone and health.
BACKGROUND Stratospheric ozone is being depleted and ambient ultraviolet (UV) irradiance is probably increasing. While remedial steps have been taken through the Montreal protocols, at best it will take some 90 years for stratospheric ozone concentrations to return to the levels existing in the 1970s. METHODS The evidence that these changes may have harmful effects on health has been reviewed...
متن کاملStratospheric Ozone Depletion
There is now strong evidence that a consequence of human activities is the inadvertent accumulation of a variety of trace gases in the earth’s atmosphere. In the past decade, these global-scale changes in the chemical composition of the atmosphere have led to a very significant depletion of the stratospheric ozone layer over Antarctica in the southern spring months and also at northern latitude...
متن کاملStratospheric Ozone Depletion in CESM
7 Observations show an increase in maximum precipitation extremes and a decrease in 8 maximum temperature extremes over southeastern South America (SESA) in the second 9 half of the 20th century. The Community Earth System Model (CESM) Large Ensemble 10 (LE) experiments are able to successfully reproduce the observed trends of extreme precip11 itation and temperature over SESA. Careful analysis...
