Through this research effort, DSR is developing test equipment that can be used by the Air Force to investigate inert and live explosive material properties through a variety of different pressure and temperature environments. Strain-rate levels are adjustable and will vary between 10-5-10-2 s-1 depending upon the stiffness and strength of the test material. 25.4-mm-diameter specimens with lengt ...

The objective of this proposed Phase II work is to develop a production method for manufacturing rolled plates of a high-strength aircraft aluminum alloy (7075) with high SCC (stress corrosion cracking) resistance. The corrosion resistance is to be improved without a loss in tensile strength. The basic operational processing procedure is to produce aluminum alloy plate through roll bonding of a co ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...

Not Available Anhydrous ammonia (NH3), a heavily used nitrogen fertilizer, is a volatile gas which flashes at -40 F. It is handles as pressurized liquid and difficult to meter accurately and dispense. Its low cost, due to inexpensive energy, has encouraged wasteful over-application rather than investment in currently costly and ineffective application control systems. Ammonia costs will increase w ...

Not Available Computational Geosciences, Inc. will develop and implement a Doppler Radar Irrigation Scheduling System (DRISS). It will be a real-time, operational system specifically designed to meet the irrigation scheduling information requirements of an irrigation district. DRISS will capitalize on the enhanced capabilities of Doppler radar technology to provide (1) a more accurate estimate of ...

This Phase II proposal is targeted towards development of novel process technology for profitable utilization of fruit and vegetable wastes. The technology will be used to recover valuable organic soluts, such as flavor and fragrance chemicals, from aqueous waste streams. In Phase I we addressed the recovery of onion flavor from an aqueous waste stream generated during the production of onion oi ...

Plants are increasingly being used to provide industry with high-value chemicals, biochemicals, and drugs. This proposal focuses on the isolation and purification of specific components in plant-derived oils. For example, L-menthod is a valuable chemical that is the major component of peppermint oil. L-Menthol is widely used in the flavoring of chewing gums, candies, desserts, and beverages; an ...
