Sodium Clusters for a Superior Light Source

Sodium lamp is one of the most efficient light sources providing an output of 150-200 lumens/watt; for comparison, light output of a fluorescent lamp is about 60-100 lumens/watt. Despite its efficient operation, sodium lamp is [...]

Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy

Omer A.M., University of Nottingham, UK

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of [...]

Technologies for Deep Reductions in Military Operational Energy Use

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Acoustic Power Recovery System for Thermoacoustic Cooling

Schwartz D.E., Garner S.R., Johnson J.R., Tuganov A.V., Palo Alto Research Center, US

In this work, we present a novel zero global-warming-potential, high efficiency thermoacoustic heat pump that can replace vapor compression systems for conventional air conditioning and refrigeration.

Testing a Geochemical Tool to Enhance Our Ability to Ensure Water Security

Slade A.T., Whitehead B.P., The University of Auckland, NZ

Chemicals that are transported in our water can be used to our advantage. Both natural and anthropogenic chemicals can be targeted to understand the way our water behaves. The use of boron isotope compositions has [...]

Dairy CAFO Wastewater, Water Harvesting and Ammonia Fuel Cells

Collins C., Hughes S., Jackson G., Spiralcat of Maryland, US

Spiralcat of Maryland has two pilot demonstration: A Dairy CAFO located within the Chesapeake Bay Watershed brings together precision agriculture and targeted air quality strategies while conserving water, and removing unwanted salts and excess nutrients [...]

Preparation and characterization of polyaniline nanofiber and nanocomposites and their applications in removal of Cr(VI) and phosphate

Najim T.S., Mustansiriya University, IQ

Polyaniline (PAN) nanofibers have received much attention owing to their superior properties compared to the conventional bulk PAN[1-3]. PAN nanofibers show enhanced water processability[4] and improved sensitivity and time response when they are exposed to [...]

Computer modeling of water and salt transport in RO membrane active layers

Pitera J.W., Na Y.-H., Vora A., Dubois G., IBM Research, US

As part of a combined computational and experimental effort to develop new reverse osmosis desalination membrane materials, we have carried out detailed equilibrium and nonequilibrium molecular dynamics simulations of the aromatic polyamide active layers of [...]
