There is an unmet demand for ultra-low-power, ultra-compact and low-cost radios to address emerging sensing and communication needs for military and commercial applications such as IoT/IoE. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by integration of a nano-scaled THz transceiver, on-chip antenna, and energy harvesting circuits in a form ...

Ballistic systems operate in flow regimes characterized by high speeds, temperatures and pressures, with reacting multiphase, multi-species fluids and fluid-structure interactions. Substantial progress has been made on methods to simulate the component physics. However, there are technical gaps remaining related to tracking the interacting physical components throughout a simulation. This project ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...

Despite their broad applications, up to date, diode pumped solid state green lasers are almost exclusively dominate the market due to the lack of low defect or defect-free semiconductor materials with high efficiency at green wavelength (480-550nm). We propose to develop compact, high efficiency, and high brightness III-nitride based green lasers. In phase I, we will focus on design, epitaxial gro ...

A human produces more than 100 Watts of waste heat during normal activity. If a fraction of this heat energy can be harvested it can replace the stored chemical energy in one or more of the batteries typically carried by soldiers in the field. The current generation batteries, such as the BB2590 are bulky and rigid. The PowerFelt material developed by Wake Forest University is ideally suited for h ...

Random numbers are essential for a growing number of modern applications. As computer speed and communications bandwidth have increased the potential for practical streaming cipher and large-scale Monte Carlo simulations have become technologically feasible. For these and other applications, ultrafast random number generators are essential. This is intuitively clear. Additionally, however, the ide ...

HYPRES, in collaboration with University of California, Berkeley, proposes to transition superconducting parametric amplifier technology into a robust line of products. In Phase I, we designed a compact package for lumped-element Josephson parametric amplifiers (LJPA) fabricated by our collaborators at MIT Lincoln Laboratory. We have also established the feasibility of digitization of the amplifie ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

Future vaccine development should focus on rapid upscale production, long-term and broad protection, and sufficient global distribution to prevent and reduce the impact of many infectious diseases and potential epidemics. Agave BioSystems proposes to develop a novel whole-microorganism vaccine inactivation strategy involving high-throughput screen of extensive radio-protectant matrices and radiati ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...
