In most studies of the net ecosystem-atmosphere exchange of CO2 (NEE) using tower-based eddy covariance( EC) systems it has been assumed that advection is negligible. In this study we use a scalar conservation budget method to estimate the contribution of advection to NEE measurements from a very tall tower in northern Wisconsin. We examine data for June-August 1997. Measured NEEo, calculated as the sum of the EC flux plus the rate of change of storage below the EC measurement level, is expected to be constant with measurement height, and we take the differences between levels as a measure of …

Morphology And Photocatalysis Of Titanium Dioxide Aerogels, Sean Kelly
Morphology And Photocatalysis Of Titanium Dioxide Aerogels, Sean Kelly
Dissertations, Theses, and Capstone Projects
Pollution of our environment has become one of the most serious problems of this century. Titanium dioxide aerogels is composed of nanocrystallites of TiO2 close-packed in roughly spherical mesospheres, which are agglomerated to form a highly-porous sponge. Aerogel morphology produces porosities of around 80% and surface area that can be as large as 1000 m2/g. The aerogels efficiently adsorb organic materials from the environment and when illuminated with UV light, decompose or oxidize the organic pollutants, ultimately to safe by-products such as CO2 and H 2O.
In this work we modify the synthetic conditions to produce aerogels with different morphologies …
