Gasoline Confined In Nano-Porous Media, Matthew Giso
Gasoline Confined In Nano-Porous Media, Matthew Giso
Honors Theses
The heat of combustion was determined for gasoline confined in nano-porous media of differing pore size by bomb calorimetry. The heat of combustion of the confined fuels was comparable to that of bulk within the experimental uncertainty. This suggests that all of the confined fuel burns without any flame quenching and no chemical interactions at the interface between pore walls and fuel mitigate combustion.

We studied melting and freezing of 2-decanol nano-crystals (100 Angstrom to 1000 Angstrom) using a Differential Scanning Calorimeter (DSC). In agreement with the Gibbs-Thompson equation, the melting temperature of nano crystals decreases with physical size and its change scales linearly with the inverse of physical size. The apparent heat of fusion of the nano scaled systems, however, has been found to be lower than the heat of fusion for the bulk. Although this is in agreement with previous experimental observations, it is in contradiction with the assumptions used to develop the Gibbs-Thompson equation. We believe that the apparent heat of …
