Renewable sources of energy including solar and wind are fast gaining ground on fossil fuels, in part because of their sustainability and environmental benefits. A major issue, however, has been finding efficient ways to store the energy that renewables generate for use when the demand for energy is high. Lithium-­‐sulfur batteries, which store electrical energy by transferring electrons to or ...

This program will demonstrate how additive manufacturing technologies can be used with reactive and high energy materials to create rapid and flexible fabrication of payload and munitions. Our primary approach to this problem will be to use powder bed binder printing techniques to print reactive structures. The anticipated feedstock will consist of composite particles containing all reactant spe ...

Micro-RDC will develop portable radiation effects test structures that scales to new process nodes. These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level. The production of the chosen structures and the development of software to extract the model parameters will form the framework. A suit ...

Establish a radiation-aware analysis capability in a commercial EDA design flow that will enable first-pass success in radiation-hardened by design (RHBD) for DoD ASICs in much the same way that existing EDA design suites ensure first pass functionality and performance success of complex ASICs destined for commercial applications. Layout-aware, calibrated single-event radiation models that captur ...

For effective protection against EMP and HPM threats, it is important to understand the physics of the threats, and also to quantify the effects they have on electrical systems. EMP and HPM vulnerability testing requires delivery of high peak power and electric fields to distant targets. The most practical solution to simulate such environments is to develop a modular, optically-isolated MV-antenn ...

There is a continuing need for high power circulators to protect the next generation of high power RF sources from waveguide reflections that can destroy the device. Currently, the power level of circulators is limited by the materials, specifically ferrites that provide the required non-reciprocal operation. New approaches are required that use materials capable of very high power operation. Stat ...

The Brayton cycle for power generation offers significant advantages over the Rankin cycle typically used. Unfortunately, the Brayton cycle uses very high pressure and high temperature, supercritical CO2 (sCO2) as the heat transfer fluid. New materials that can handle the harsh environment of sCO2 are required to enable power generation and prevent issues with corrosion and erosion or efficiency d ...

The Department of Energy has a mission to ensure America's prosperity and security by addressing energy and environmental challenges. This Phase I project aims to produce domestic, economic and environmentally responsible biodiesel fuel from brown grease, a waste that is currently disposed in landfills or incinerated. The conversion of "brown grease" from wastewater treatment plant’s fats oils a ...

There is an increasing need to understand the impacts particles emitted by both natural and human activities have on cloud properties, precipitation and climate. DOE has identified a need to improve the measurement capability of observational platforms, particularly in the Arctic region. One barrier to progress in understanding the interactions of particles and clouds and the importance of cloud c ...

High brightness and high average power Free Electron Lasers known as x-ray FELs, developed by DOE, are intently desired by the scientific community for their unique capabilities and for the opportunities they enable in the medical and biological sciences, such as imaging biological molecules or chemical reactions. Beam optics codes (particularly Particle-in-Cell codes) couple non-uniformity and su ...
