Final Report Abstract

The project explored a new transport approach, which supports the localized collection of airborne particles at a higher rate than previously possible. Strongly simplified the process is an electrodynamic Coulomb force directed transport process. Specific experiments achieved the main goal and discovered missing fundamental elements and an expanded model of gas phase electrodeposition. The research on the expanded model identified two key parameters: carrier gas flow rate and spark discharge power. Both parameters affect electrical current carried by charged species, nanoparticle mass, particle size and film morphology. During the project, four key discoveries were made, which were used in three applications leading to nine journal publications. In addition to the project, knowledge was generated for two further cooperative publications. In addition to the project, three further discoveries have recently been made which have not yet been published but offer potential for further research.
