The widespread use of per- and polyfluorinated alkyl species (PFAS) chemicals for commercial products and industrial applications has resulted in bioaccumulation of these chemicals in the environment and a public health hazard. Development of novel approaches for in situ degradation of PFAS in industrial and landfill wastewaters would greatly facilitate efforts to prevent discharge of these hazard ...

Due to release of industrial and landfill effluent into the environment, per- and polyfluorinated alkyl species (PFAS) have been accumulating in soil, sediment and groundwater, with subsequent absorption by living organisms. PFAS have the potential to cause multiple adverse health effects, including low birth weight, accelerated puberty, and cancer. Novel approaches for in situ degradation of PFAS ...

In the Phase II project, METSS will continue the development of a safe, robust, rapid, and effective chlorine dioxide (ClO2) gas dispersion system to be used for on-site room decontamination in hospital and non-hospital settings. The heart of the decontamination system is a proprietary ClO2 generating micro-reactor technology that is used to quickly and safely generate ClO2 on-site. This technolog ...

Army missions require robust, error-free transmission of video data without network errors. In compressed data, such as with H.264 or H.265 compressors, small bit errors can obliterate large portions of the de-compressed image, or render it un-compressible at all, depending upon where in the compressed data the errors occur. Dropped packets may obliterate frames containing significant mission-crit ...

Idaho Scientific presents a Risc-V based secure processor architecture that provides unique security properties complimentary to the seL4 microkernel. The work conducted under this Phase I SBIR effort will further the discipline of computer security by mitigating memory corruption vulnerabilities, enforcing strong processes separation, covering seL4's formal verification assumptions, and provide a ...

The repair and rebuilding of injection molded parts is an important activity at army depots. The unit cost to make small batch parts is quite expensive due to the high cost and long lead time for injection molds for tooling. Fused Filament Fabrication AM offers a viable alternative to reduce tooling costs and lead time, however most AM thermoplastics do not meet the stringent requirements of high- ...

Opioids are a class of potent analgesics used for both pain relief and their euphoric effects. The range of effective doses stretches across multiple orders of magnitude, down to micrograms per individual for a lethal dose. With such low doses causing significant intoxication, it is crucial to identify novel markers and means to monitor for opioid exposure both on the battlefield (opioid chemical ...

The nature of complex combat operations must now include adversaries that have peer-level capabilities, such as the ability to locate friendly troops by their transmissions and jam their radios so they can’t call for help, setting them up for attack. However, critical to all combat scenarios, regardless of adversary capability levels, is the need to command, control, communicate and exchange inf ...

The objective of this proposal is to enable high-sensitivity, passive imaging system of natural mm-wave emissions, which can be used as standalone or fused with other imaging modality such as conventional IR imagery in degraded environments. This is achieved through a unique antenna integrated electro-optic (EO) modulator, where received mm-wave signals modulate an optical carrier. The optical car ...

To date, Simultaneous Transmit and Receive (STAR) solutions have primarily relied on a circulator in the RF frontend, paired with digital signal processing (DSP) to suppress the approximately known transmitted signal. These techniques have demonstrated only limited isolation and bandwidth and struggle to remove non-linear harmonics and transmit noise. Moreover, the limited isolation of circulators ...
