Single chirality of single-walled carbon nanotubes (SWCNTs) is critical for their superb mechanical, thermal, optical and electronic properties. All known methods for producing nanotubes give mixtures of tubes with different chiralities. Physical separation of SWCNT by chirality is thus an enabling step for many potential applications and fundamental studies. The existing anion exchange resins are ...

Invention House LLC proposes to lower the initial cost of solar energy by minimizing the material used in the reflector of a concentrating trough. Placing the support structure on the front (sun) side and using a thin reflecting membrane will reduce material usage and cost by approximately 66%. The system is capable of producing boiling hot water for use in grain drying, food processing, and steri ...

ABSTRACT: Flight tests of hypersonic maneuvering vehicles are a challenging but necessary endeavor. While ground tests and numerical simulations can provide important guidance regarding vehicle performance, they are both limited in their reach. Likewise surface-based measurements during flight tests provide valuable information, but do not provide sufficient insight into the complex flowfield t ...

ABSTRACT: We propose to apply modern massively multicore processors to a key problem area of interest to the Air Force: multiphysics computational fluid dynamics (CFD) and computational structural dynamics (CSD) solvers. The capabilities of the CPU to solve these problems have been increasing steadily, but the CPU is still a general-purpose device designed to run diverse applications such as word ...

ABSTRACT: Crystalline semiconductor nanomembranes (NMs) possess the electronic/photonic properties of bulk material, although they are flexible, deformable, and conformable. Semiconductor nanomembranes offer unique opportunities for novel active/ passive electronic, and photonic devices suitable for vertically stacked high-density photonic/electronic integration. Silicon-on-insulator substrates. ...

Typical agrochemical sprayers use nozzles to atomize a liquid stream into droplets; these droplets then travel to the target. Nozzles may be selected to provide a range of droplet sizes, spray distribution patterns, and flow rates for a desired liquid material application. Spray distribution, droplet size, and flow rate are important considerations in achieving a high quality agrochemical applicat ...

Vapors produced during the process of refueling cars are a significant source of Volatile Organic Compounds (VOCs) emissions. Uncontrolled emissions cause economic losses and pollute the environment. This problem is exacerbated when the gasoline contains bioethanol because its presence increases the vapor pressure and volatility of the fuel. These increased fuel emissions from ethanol-gasoline ble ...

Soybean is the major source for production of edible oils worldwide and in United States. Pressing of the soybean into flakes followed by the solvent extraction with hexane (solvent) is most widely practiced for extraction of oil. Separation of solvent from oil-solvent mixture for solvent recovery and reuse is usually carried out by solvent evaporation. Evaporation (or distillation) demands consid ...

The U.S. population has a deficit of dietary calcium that represents a serious challenge to public health. Many consumers, however, find current methods of increasing dietary calcium to be inconvenient, costly, or unpalatable. This SBIR Phase II proposal seeks to increase calcium levels in lettuce, a specialty crop that already comprises a significant part of the average U.S. diet. Successful Phas ...

Use of an airborne platform for a directed energy system is currently severely limited by aero-optic aberrations arising from density variations in air flowing over the aircraft; the primary limitation is for aft pointing applications. Innovative Technology Applications Company (ITAC), in collaboration with the University of Toledo (UT), is working to develop techniques of integrating flow control ...
