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 ...

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 ...

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 SBIR/STTR project targets the development of a validated modeling/design tool for predicting the behavior of spouted fluidizied beds for chemical looping combustion/gasification applications of coal and biomass fuels and fuel blends. Chemical looping is an advanced energy conversion technology for generating a pure CO2 effluent, which can then be sequestered or utilized. A spouted fluidized b ...

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 ...

Density functional theory is used by many researchers funded by the Department of Energy as a method for predicting the behavior of chemicals and materials used in energy applications. However, results of these calculations are often not standardized and, even when they are, expert-level understand of the methods is needed in order to properly perform a simulation. The energy research community a ...

The rate of climate change in the Arctic is larger than elsewhere on Earth. The Arctic has unique and complex couplings and feedbacks between the surface and the atmosphere that in turn modify the radiative balance there differently than elsewhere. Current understanding holds that an increase in downwelling long wave radiative flux, driven by increased water vapor and clouds, may be accelerating c ...

Despite incremental improvements in the technology, polyfluorosulfonic acid (PFSA) membranes are still not an ideal fuel cell membrane material and their drawbacks (e.g., high cost and low mechanical strength at high temperature) require development of alternative polymer electrolyte membranes (PEMs) for successful adoption of fuel cells as reliable and inexpensive energy conversion devices. The g ...
