ABSTRACT: Energetic composite materials comprise crystalline energetic particles embedded in a polymer matrix. There is a need to gain insight into the microstructure and damage mechanisms of energetic composites via nondestructive evaluation. Applications of x-ray computed micro-tomography to resolve the microstructure of energetic composites are challenged by the low density gradient between th ...

Colloid thruster technology continues to be attractive for spacecraft propulsion, especially since its specific impulse can be many times greater than even the best bi-propellant chemical rocket. However, the technology was abandoned in the 1970s due to low charge-to-mass ratios, which lead to excessively high voltages and large inert mass fractions. The recent advent of microelectromechanical s ...

Successful training in complex environments is normally accomplished through the interaction of a trainee and a skilled expert, but due to resource constraints, experts’ use in training can be problematic. Using an optimal model of task performance subject to human constraints may be a more efficient way to develop models of skilled human performance for use in training, especially since optima ...

Objective The objective of this project is to develop an organic solution-based CMOS process capable of producing printed RFID tags. Key to this objective is to optimize the n-type semiconductor and dielectric materials developed in Phase I, and to integrate these materials into a complete process line. The Approach CMOS utilizes p-type and n-type transistors to significantly reduce static power d ...

High performance energetic materials are based on inorganic thermite mixtures such as MoO3/Al or organic compounds such as RDX. Future developments in explosives are dependent on the fabrication of nanoscale materials and composite mixtures that display higher energy release rates. The ability to tailor composite materials precisely at the nanoscale by fabricating multilayer component particles ...
