Many DOD systems employ rechargeable batteries to supply power. Battery weight, volume, cycle life and cost are generally limited considerations in enabling satisfactory mission performance. Systems presently utilize Lead-Acid, Nickel-Cadmium, Nickel-Metal Hydride or Lithium-Iobatteries. The Nickel-Metal Hydride (Ni-MN) system is now under study as a superior candidate for many applications. El ...

Those battery systems that are currently readily available (lead-acid and nickel-cadmium), as well as those that are only now becoming a vailable in limited sizes and capacities (nickel-metal hydride and lithium-ion), can provide ample power for most portable equipment applications but the energy density/specific energy performance often resultsin inadequate run times. In contrast, the zinc-ai ...

Yardney Technical Products proposes to develop low cost, long life, safe and environmentally benign lithium-ion batteries ideal for applications sensitive to operational and disposal costs as well as safety andperformance criteria. Phase I of the proposed project will focus on the selection and development of battery materials. A lithiated manganese oxide will be selected as an active cathode ma ...

AJT proposes to develop a low-cost, engine test-stand system for small (500 pound) thrust engines using gaseous, liquid or cryogenic propellants. This test stand would incorporate automated propellant transfer and automated propellant line purge systems. The engines would be configured to a standard test-stand interface, greatly reducing the time required to install and remove various engines. Thi ...

The Space Station Biological Research Program at NASA is developing advanced facilities, including cell culture systems to conduct microgravity research in cell biology onboard the Space Station. These systems will provide basic and essential infrastructure for space-based cell biology research. However, full utilization of the Space Station biological research facilities will require additional i ...

Rotating wall vessels (RWV) are widely used for cell culture in simulated microgravity conditions. Sensor technologies capable of monitoring the expression of proteins on a large scale (proteomics) are needed to fully exploit the unique capabilities of RWVs. This Phase II effort is part of a program to develop an advanced analytical monitoring system for quantitative detection of bioreactor biopro ...

For flight experiments in low earth orbits and planetary missions, an innovative electrode structure is proposed to obtain a metastable helium ionization detector of active volume down to a fraction of a microliter for use with microbore and microchannel gas chromatographs. Such a small detector volume is achieved by the special electrode structure and gas flow pattern. In Phase I, the detector st ...
