Compact Membrane Systems membranes have shown very stable performance. Operating for over 270 days with propylene/propane showed propylene flux of 175 GPU and propylene/propane selectivity of 30. Even more impressive was operation of 75 plus days in the presence of hydrogen sulfide foulant that showed propylene flux of 175 and selectivity of 25.

This proposed research project responds directly to the need of a high-efficiency continuous-wave microwave source at a frequency of 1.497 GHz delivering at least 8kW of power. This research will provide a klystron with an overall efficiency of 82% and a high degree of backwards compatibility to allow its use as a replacement for klystrons currently used today, which are only 35% efficient.

In the DOE SBIR topic “Advanced Digital Network Technologies and Middleware Services”, the Office of Advanced Scientific Computing Research seeks grant applications for developments in advanced optical network technologies that enable DOE scientists to communicate with peers, and collect/process data at Gbps data-rates. Providing Gbps wireless connection is a challenge in last-mile networks as ...

for the batteries, PM motor and electric drive train while simultaneously reducing weight. Increasing the drive train conversion efficiency has a significant impact as it extends battery life, vehicle range and allows for a reduction of heavy cooling components through the reduction of heat generating losses. Therefore much attention is placed on increasing the efficiency of the traction power inv ...

Reducing the size, weight, and increasing the efficiency of automotive traction power inverters requires the development of novel high voltage, high current silicon carbide high speed rectifiers, since the existing silicon technology is severely limited in terms of operating temperature, frequency and energy efficiency. However, the non-optimized device and manufacturing technology currently used ...

Heavy metals such as lead, arsenic, chromium, mercury, and cadmium have attracted significant worldwide attention for their impact on human health. To allow the efficient monitoring of such RCRA 8 heavy metal levels in water in steam electric power plants and other facilities, a precise, mobile and highly sensitive measuring instrument is required. Traditional laboratory based water analysis syste ...

This project will create a new category of advanced all Silicon Carbide power inverters for use in energy storage in the medium voltage range and > 100 kW ratings. A design showing a significant increase in circuit efficiency, cost reduction, an increase in power density, and a reduction in thermal management requirements over the existing Silicon power inverters will eliminate significant waste o ...

High speed imaging of plasma spectroscopy is limited to relatively short record lengths and requires low light sensitivity which is very expensive. Silicon Photomultipliers (SiPM's) are a new solid state device that can replace conventional photomultipliers. When leverageing SiPM detectors, portions of the tradeo space where slightly reduced spatial resolution allows gains in record length and re ...

Marine and hydrokinetic (MHK) energy converters are often installed in remote, harsh environments where access is limited and maintenance is a costly and labor intensive process. The lack of real time information on the status and health of critical structural components prevents the adoption of condition based maintenance strategies, and thus requires the use of preemptory maintenance practices. ...

Nuclear power plant (NPP) operators are required by the Nuclear Regulatory Commission (NRC) to perform cybersecurity assessments on their internal networks, control systems and critical data assets on a regular basis to ensure regulatory compliance and safety, security and emergency preparedness of the nation’s most critical infrastructures. However, the current assessment processes in the nucle ...
