Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEA’s) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry. In this project, a new method is suggested, which can qualitatively and quantitatively measure different surfact ...

As the human population grows, it is critical to decrease consumption materials from the planet and its ecosphere. The world adds 70 million people annually. The UN expects the population to grow to over 9 billion 2050. Climate change, soil degradation, ...

In the Phase I SBIR, the SpaceWorks team proved the technical feasibility of a modular persistent platform in GEO based on the assembly of individual spacecraft each sized to the DARPA POD form factor. The team also determined that such a platform would ...

Inertial Measurement Units (IMUs) for flight systems (interceptors, airborne platforms, and space assets) are constrained by limits on size, weight, power, and cost (SWaP-C). These IMUs are also exposed to severe shock and vibration during storage, transport, launch, staging, deployment and engagement. This Phase II effort will continue research from the Phase I and achieve three main objectives 1 ...
