Award Data

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

Industrial hydrogen production relies primarily on natural gas and hydrocarbon feedstocks to drive the various reaction chemistries that lead to hydrogen generation. Carbon dioxide, the ultimate co- product when such feedstocks and processes are employed, necessarily becomes a major contaminant of the generated hydrogen. Thus, carbon dioxide isolation and removal is an important process step in ...

Inductive pickup loops are one of the primary magnetic diagnostics in modern fusion concepts. To convert the voltage measurement from the inductive pickup loop to a measurement of magnetic field, the loop voltage must be integrated. While simple in principle, in practice several factors make the integration difficult, especially when there are large scale differences between the fast and slow magn ...

A high energy density capacitor with superior life and reliability will be developed that is a key component of power semiconductor inverter circuits, used in automotive hybrid and electric vehicles, rail transit, wind power generators, photovoltaics, and transportable energy storage systems for grid applications.

Advanced rotary shear technologies from this project will reduce the cost of reactor-ready feedstocks and improve the energy balance for advanced biofuels, thus moving the nation towards import oil independence.

This project will develop high performance sealing plugs for use in deep borehole disposal of nuclear waste and commercial wells. The technology provides a high strength, high corrosion resistant well sealing material superior to conventional cements.

With no moving parts other than a syringe pump, this tool will allow for the reliable measurement of flow rate as a function of depth within a geothermal wellbore and thus provide for improved reservoir management. By improving wellbore flow measurements, predictions of well performance will dramatically improve and EGS energy production will become more reliable and more cost effective.

This Phase I proposal determines the feasibility of growing multiple species of macroalgae in commercial marine aquafarm environments. Marine aquaculture is a logical outgrowth of successful wild harvest seaweed businesses over the last several years. Developing a marine aquaculture prototype will foster the science of sea farming. Extending growing seasons for multi-species would provide year ...

Oxygen enriched air (OEA) can be a valuable tool to enhance combustion processes, reduce CO2 emissions per unit of heat generated and also concentrate CO2 to enhance subsequent CO2 concentration ahead of CO2 sequestering. OEA reduces the presence of parasitic nitrogen and therefore flame temperature and associated heat transfer is higher with OEA. Studies show that using 40-50% OEA, which is the p ...

Switching power amplifiers (SPAs) have a wide variety of applications within the fusion science community, including feedback and control systems for dynamic plasma stabilization in tokamaks, inductive and arc plasma sources, Radio Frequency (RF) helicity and flux injection, RF plasma heating and current drive schemes, ion beam generation, and RF pre-ionizer systems. SiC MOSFETs offer ...
