Nanothermite Metastable Intermolecular Composites and Aerosol Dynamics

This study by Zachariah McCormick focuses on the synthesis of metal oxide nanoparticles and the development of a pressure cell apparatus for measuring kinetics. Various computational and experimental approaches are used to explore aerosol dynamics, including nucleation, coagulation, and surface growth. Current directions include synthesizing porous oxidizer particles and studying the effects of loading the oxidizer pore with nitromethane.

  1. In-line charge amplifier Oscilloscope Signal conditioner Sample Pressure Sensor Nichrome McCormick, Zachariah Developed an aerosol-based sol-gel method for making metal oxide nanoparticles with high internal surface area and nanothermite metastable intermolecular composites Developed pressure cell apparatus for measuring kineticsof mixtures of oxidizers with Alin terms of pressurization rate:

  2. McCormick, Zachariah (cont.) A nodal algorithm and software were developed to solve the aerosol general dynamic equation (GDE)with size-dependent surface tension Size-dependent surface tension for Al at 1000 K from molecular dynamics simulation: Including this variation allows more realistic simulations of nucleation, coagulation, and surface growth.

  3. McCormick, Zachariah (cont.) Snapshots of MC simulation Monte-Carlo Simulation for Two-Component Aerosol Nucleation, Diffusion, and Coagulation time Aggregating nanoparticles in an evaporating aerosol droplet (initial number of solute particles 25,000; relative humidity 50%)

  4. McCormick, Zachariah (cont.) Current directions of computations • Experimental work in progress • Using polystyrene-latex to synthesize porous oxidizer particles (CuO) with organized pores • Studying the effect on nanothermite reactions of loading the oxidizer pore with nitromethane • Synthesis of aluminum by thermal cracking of an alane aerosol. • Parallel programming for larger-scale calculation • Two-component 2-D code that accounts for • viscosity • local concentration • nucleation • growth of aggregated particles • phase segregation and reaction
