Abstract:

The objectives of this project are to fundamentally understand the interaction between spore forming bacteria and thermite reactions and products and to exploit energetic material reactions with biocidal properties to destroy bacteria and investigate how the properties of individual nano-scale particles influence their macroscopic combustion behaviors and mechanisms of interactions with spore forming bacteria. These objectives will be addressed through examining the response of spores exposed to gas generating thermites that include iodine or other halogen species that demonstrate the potential to neutralize bacteria. This investigation will characterize the gas phase chemical species responsible for bacterium neutralization as well as examine the thermal and physical effects, such as exposure time, on spore destruction. Reaction kinetics of the candidate thermites will also be studied to elucidate the mechanisms of destruction.
