Innovation: The Cleaned and Green (C&G) enhanced efficiency fertilizer (EEF) technology is a cost-effective, environmentally friendly, and beneficial solution to the use of poultry litter. Litter applied raw, dried, or composted can negatively impact the environment and is impractical and unhealthy to transport long distances. C&G technology converts raw poultry litter to a superior, valuable, nut ...

In this innovative Phase I effort, nSI will construct and demonstrate an empirically driven directed evolution model that rapidly selects for BBB-crossing NPs in vitro, as a proof of concept. Leveraging cutting-edge NP formulation advances, we will (1) synthesize a library of DNA-barcoded NPs, (2) administer the library in multiplex to in vitro BBB models, (3) use the BBB infilitration data collec ...

The overall objective of the Phase II effort is to further investigate the generations of RF emissions from the detonation of high explosives and how those signatures maybe used to further understand the complex interactions within an event as well as the physics responsible for their generation. To accomplish this objective, IS4S will conduct an optimized series of experiments based on the lesson ...

The potential of explosive energetics has long elicited the need for understanding, control, and optimization. Scientific theory, development, and experimental investigations collaborate to create applications for offensive and defensive strategies. Visual evidence of ionization, subsequent recombination, and shockwave interaction indicate that dynamic electrical potential distributions are intrin ...

Improvised Explosive Devices (IEDs) are a dangerous and effective weapon system that today’s military warfighters and innocent civilians regularly experience. IEDs are created with randomly assembled materials and their payloads may include projectiles, biological toxins, and other dangerous items that can cause injury or death to personnel and equipment. Detection and neutralization of these we ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is crucial to detect proliferation of nuclear material. Critical challenges include: (a) high sensitivity detection of signature emissions from radioactive isotopes, and (b) cost-effectiveness for deployment of sensor networks across large storage facil ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

Cost-effective application of advanced commercial electronics technologies in DoD space systems requires early development of radiation-hardened-by-design (RHBD) techniques, and use of simulations is critical to the efficiency of this process. CFDRC has developed an integrated, mixed-mode simulation approach allowing their NanoTCAD device physics simulator to interface with commercial circuit simu ...

The proposed ultra-fast shutter achieves all design requirements for hypervelocity debris mitigation in the EUV cold x-ray Z-machine experiment using a high reliability magneforming shutter which has been field tested hundreds of times under conditions very similar to the Z-pinch machine. The proposed device is based upon the electromagnetic hypervelocity debris mitigation shutter put into operati ...
