Although the dynamics of methane (CH4) emission from croplands and wetlands have been fairly well investigated, the contribution of trees to global methane emission and the mechanisms of tree transport are relatively unknown. Methane emissions from the common wetland tree specie…
In these times of striving for cleaner, more efficient fuels, research is needed to provide understanding that will allow technologies to improve. Planar laser induced fluorescence (PLIF) is a popular, non-intrusive technique for studying flame structure. A radical species, hydr…
Wetlands contribute an estimated 25% of the global annual methane (CH4) emissions. However, delineation of the processes responsible for the large variations in emission rates found within and across wetland types has been challenging. Field measurements were collected in Franci…
This body of work expands the understanding of in situ cosmogenic 14C production and retention in the upper layer of accumulating ice sheets and presents new measurements of 14CH4 that improve our understanding of the fossil component of the CH4 budget. Samples were collected at…
As a result of stricter environmental regulations worldwide, hydrogen is progressively becoming an important clean energy source. For H2 to replace fossil fuels in mobile applications, it will require the creation of a production and delivery infrastructure equivalent to that cu…
