In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

This Small Business Technology Transfer Research (STTR) Phase II proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline tungstate ceramics with densities greater than 99.95% and a mean grain size of less than 1 um. These ceramics have been chosen because of their low thermal expansion and low elastic ...

This Small Business Technology Transfer (STTR) Phase II project will transform the Hybrid Optimization Model for Electric Renewables (HOMER

This Small Business Technology Transfer (STTR) Phase II project aims to develop a manufacturing process to synthesize metal oxide, sulfide and other nanoparticles. The subject method simply involves mixing of common dry chemical starting materials and heating the resulting precursor material to a modest temperature. The objective is to demonstrate feasibility and scalability of this low-cost man ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

To meet Navy needs for high performance and safe lithium ion (Li-ion) batteries for naval aircraft, ADA Technologies Inc. (ADA) and its university collaborator propose to optimize and transfer a highly tunable, high performance and safe, block copolymer derived nanoporous separator. The innovative strategy provides a powerful tool to allow exquisite tuning of performance and safety features of the ...

The United States is currently faced with unprecedented energy challenge. Petroleum prices have skyrocketed due to rising competition for energy resources from emerging economies. There is a significant need for processes that can produce hydrocarbons from renewable resources rather than petroleum. The use of renewable resources ensures a long-term supply of hydrocarbons, even after easily extract ...

During the Phase 1 effort, there were several achievements toward the design of grounding systems for MVDC architectures. For one, the common-mode equivalent circuit (CMEC) modeling approach that was derived at Purdue under ESRDC funding, was validated in a reduced-scale hardware setup at Purdue. The system studied consisted of a single generator, active rectifier, inverter, and propulsion machine ...

During the Phase II effort, the ISSAC Team will investigate several objectives and questions posed in Phase I efforts, in order to best develop a draft specification for NGES MVDC DLI systems. This includes exploring notional and conceptual architectures and discerning thresholds for DLI parameters; exploring individual and hybrid protection plan technologies to drive performance requirements for ...

The purpose of this Phase II project is to develop computational modeling methods that are able to describe the propagation and interaction of fatigue cracks using the phase-field methodology within the numerical framework of isogeometric analysis (IGA). The resulting computational platform, while focused on fracture and fatigue, will be general, in that any phase-field method can be easily incorp ...
