Deliquescence Behavior of Sodium Borohydride and Steam

Oct 16, 2011
Hong Liu
Sodium borohydride as an effective, cheap and stable material for hydrogen storage has been studied widely. Despite prior studies [ 1-5 ] on the steam hydrolysis of NaBH 4 , the mechanism for the release of hydrogen by water vapor/ NaBH 4 contact has not been well understood. Recently, Beaird et al...

Forward Osmosis: Potential Use In Desalination and Water Reuse

Oct 16, 2011
Ali Altaee
Abstract There has been a recurring interest in using Forward Osmosis (FO) process in water treatment and desalination. The recent advance in membrane technology has encouraged further investment in the process technology. Despite the promising results from pilot and bench scale experiments the...

Energy, Water, Sustainability for a Smarter Planet

Nov 7, 2010
Spike Narayan
Over the last few years, our eyes have been opened to global climate change, and to the environmental and geopolitical issues surrounding sustainability. As an example, by 2015, more than half of the regions in the world will experience some level of stress in water supply and management. Similar...

Water and Energy: Integrated Challenges, Integrated Solutions

Nov 7, 2010
Jared Ciferno
Water, once considered a nearly inexhaustible resource, is becoming increasingly limited, and water requirements for electricity production must compete with other demands, such as agriculture and sanitation. The Department of Energy's (DOE) Fossil Energy Program is conducting a considerable R&...

Fouling Monitoring Techniques for Water Treatment Membrane Processes

Nov 7, 2010
Kuo-Lun Tung
Membrane fouling and flux decline are undesirable, albeit inevitable, problems in membrane filtration processes for water treatment. The development of low fouling membranes, the design of high efficiency modules, the selection of optimal operational strategies, and several improvements made in...

Hydrogen Production by Reforming of Logistic Diesel Fuel in Supercritical Water

Mar 23, 2010
Carsten Cremers
Compared with other fuels, diesel fuels still have significant advantages in terms of logistic properties such as energy density, availability and ease of handling. However, diesel fuels also have their draw backs. For an example, the only established technology to convert the chemical energy of...
