Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

Rugged field spectrometers with no moving parts are needed for detecting chemical, biological, and explosive threats using the long wavelength (LWIR) spectrum. QuantaSpec has successfully designed and developed a no moving parts spectrometer with a spectral range of 7 to 12 microns in a past project. QuantaSpec has also built a functioning Wollaston prism spectrometer. This proposal will implem ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened digital memory in aerospace and defense applications and in long-life, high-speed memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight with device redundancy and shielding. Recent focus on Graphene and its capabilities ...

ABSTRACT: Structural monitoring of the landing gear of fixed and rotary wing aircraft is of critical importance to the Air Force. These structures are subjected to repeated large dynamic loads that are highly variable in nature. In order to track these structures"fatigue over time, the magnitude and direction of load events and the number of fatigue cycles must be recorded. Smart, embedded mult ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened, non-volatile (NV) memory in aerospace and defense applications and in reliable, long-life, high-speed NV memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight. Recent refocus on magnetic memory technologies, stemming f ...

Standoff detectors are required to detect IEDs. These detectectors are needed to save the lives of American soldiers. QuantaSpec has developed patent pending methods for long-range, sensitive, and selective standoff detection of explosives. These methods have already demonstrated sensitive remote detection of explosive vapors under previous efforts. QuantaSpec's multidisciplinary team will dem ...

DESCRIPTION (provided by applicant): Our research is focused on the potential of acid-prepared mesoporous silica (APMS) as a delivery agent for siRNA constructs to inhibit the ERK1/2 and ERK5 pathways in the treatment of human malignant mesothelioma (MM). These pathways are critical to MM cell proliferation and chemoresistance. Our initial research suggests that APMS will be significantly more eff ...
