Redox flow batteries (RFBs) have the potential for economical storage of electrical energy than other battery chemistries. They use high-cost ion exchange membranes as separators between anolyte and catholyte, which prevent broad market penetration. Proton exchange membranes (e.g., Nafion) are poorly selective, allowing undesired cross-diffusion of active species in solution electrolytes across t ...

This Small Business Technology Transfer (STTR) Phase 1 project will lead to the development of a simple, cost effective technology which can recover helium from gas reservoirs containing helium concentrations too low to permit economic recovery at present. This will enable helium recovery from fields currently producing natural gas but considered uneconomical for the recovery of the contained heli ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

A STEAMFLOODING/STEAM GENERATION SYSTEM IS PROPOSED FOR DEEP, HEAVY OIL RESERVOIRS. THIS CONCEPT MINIMIZES THE DOWNHOLE HEAT LOSSES, IMPROVES RELIABILITY AND REDUCES THE COST OF STEAM GENERATION. ITS FEATURES WILL MAKE STEAMING OF VERY DEEP WELLS (BELOW 7500 FEET) TECHNICALLY AND ECONOMICALLY FEASIBLE, AND WILL IMPROVE THE ECONOMICS OF SHALLOWER WELL STEAMFLOODING. THIS NOVEL CONCEPT SUPPLIES HEAT ...

TO ACHIEVE PRECISE SHAPING OF DENSITY PROFILES IN FUSION REACTORS WITH PELLET FUELING, INJECTION VELOCITIES OF UP TO 10 KM/SEC MAY BE REQUIRED FOR PELLETS OF A FEW MILLIGRAMS IN MASS. PRESENT PELLET INJECTORS BASED ON THE PNEUMATIC GUN OR CENTRIFUGE PRINCIPLES ARE CAPABLE OF ATTAINING VELOCITIES OF ABOUT 2 KM/SEC, AND THE BASIC CONCEPTS DO NOT APPEAR TO BE EASILY SCALABLE TO HIGHER PERFORMANCES. A ...

In this project we will develop a framework for and demonstrate the feasibility of a neural signal processing system for informing cognitive models. Specifically, we will use single-trial analysis of EEG to inform a cognitive model of socio-cultural behavior. Our framework will include 1) a methodology for mapping characteristics of neural signals to cortical processes and cognitive modules, 2) a ...

The recent disclosure of sensitive and classified government documents through WikiLeaks demonstrates a new systemic threat, exfiltration and broad global broadcast of government confidential data and information. We propose to develop techniques and mechanisms for identifying likely malicious insiders within an organization by leveraging automatically generated misinformation and modern system an ...

Increased use of hydrogen as a fuel can provide benefits to our nations energy security, the environment and economic growth. Toward hydrogen economy, an innovation in hydrogen separation technology is needed in the production of hydrogen. Current separation technologies for industrial hydrogen production mainly include pressure swing adsorption process and the cryogenic separation process, which ...
