This Small Business Technology Transfer (STTR) Phase I project will demonstrate the feasibility of a two-phase controllable flow in microchannels. The fluid consists of a carrier fluid, nano-magnetic particles, and additives. The proposed work will also produce low-cost, nano-magnetic particles using a novel scaled-up synthesis process. The objectives of the proposed research are to design a large ...

Recreation trails are a key component of the social, economic and health of rural communities. People with mobility impairments are often excluded from trails, shared-use paths, parks and other public areas where barriers are erected to prevent access by motorized trail vehicles (MTVs), to control livestock or wildlife, as an access point in a fenced area, or for a variety of other reasons. Many p ...

This Small Business Technology Transfer (STTR) PhaseI project will design, fabricate, and validate a novel low cost (under $40/kW), robust and high-power-density 3 kW fuel cell (FC) power-conditioning system (PCS) suitable for lower voltage FC stacks, comprising a high-frequency inverter (HFI) followed by a forced cyclo-converter, which yields the following features: (1) 300 kHz switching frequen ...

The invention of Electrically Controlled Extinguishable Solid Propellants (ECESP) over the last five years opens the door for completely new ways of controlling solid rocket motors. When the propellant is fitted with electrodes and a current of the required voltage is applied, the propellant ignites and continues to burn until the voltage is removed. Throttle control and multiple restarts have b ...

The project focuses on the development of a small, water-proof elecromyographic (EMG) sensor for a myoelectric arm prosthesis that transmits by a wireless link and can be easily and consistently installed over any muscle site. The wireless link eliminates wires and connectors inside the arm socket that can be bulky and unreliable due to corrosion and breakage of wires representing a significant i ...

Develops a small waterproof Warless EMG Preamp sensor for myoelectric arm prostheses that transmits a digital signal via a wireless link eliminating many of the wires and connectors associated with arm prostheses and allowing connection to modern rollon gel type liners

The remarkable sensitivity, compactness, low cost, low power-consumption, scalability, and versatility of microcantilever sensors make this technology possibly the best solution for container screening. In Phase I, Nevada Nanotech Systems (NNTS) successfully demonstrated all components of a prototype sensor system for measuring the concentrations of unlawful or hazardous materials in shipping con ...

This Small Business Innovation Research (SBIR) Phase II project will extend the applicability of the multi-environment probability density function (MEPDF) method to model turbulent combustion problems with realistic chemical kinetics within comprehensive Computational Fluid Dynamic (CFD) simulations of practical combustion equipment. The project aims to further advance the MEPDF method by extendi ...

This Small Business Technology Transfer (STTR) Phase I project is to determine the feasibility of developing a hydrodynamic combustion stability analysis design tool for rockets, gas turbines, and large engines. As combustors are run at leaner mixture ratios to avoid NOx pollutant issues, vortex liquid rocket engines are designed with swirling flows to cool engines, and solid rocket motors are bui ...

Components used in missile propulsion and control systems such as Throttling Divert and Attitude Control Systems (TDACS) are susceptible to damage and degradation under the harsh operating conditions. Notwithstanding such conditions, a monolithic variant of the “NZP” ceramic has been successfully utilized by Aerojet for TDACS components in MDA’s GMD and SM3 missiles. For more advanced soli ...
