In May 2011, the authors participated in the 2011 Renewable Energy Conference: “Supporting Sustainable Development for Iraq” sponsored by the Iraqi government with assistance from the U.S. Civilian Research and Development Foundation. The conference was [...]
Acoustic Power Recovery System for Thermoacoustic Cooling
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.
Technologies for Deep Reductions in Military Operational Energy Use
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 [...]
Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy
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 [...]
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 [...]
Structural and Thermo-Mechanical Characterization of Calcium and Barium Alginate Films
Alignate films require its precise characterization of mechanical and thermo-mechanial properties, which are useful for several potential applications in environmental protection, biotechnology, and others areas. Therefore, this work study the aforementioned film properties of sodium [...]
CNT-polyamide nanocomposite membranes for gas and water separations
Marand E., Surapathi A., Chan W.F., Chen D., Chen H., Chen D., Chen H., Shao X., Johnson J.K., Virginia Polytechnic Institute and State University, US
We have developed asymmetric carbon nanotube/polyamide membranes for desalination applications. The carbon nanotubes are functionalized with zwitterionic groups that control the rejection of anionic species, while permitting the transport of water. Water flux measurements demonstrate [...]
Enhanced RO Performance of Polyamide Bi-layer Membranes Prepared by Sequential Interfacial Polymerization
Na Y.-H., Nassar M., Diep J., Davis B., Vora A., Dubois G., Al-Rasheed R., Nassar M., Geise G., Freeman B., IBM Almaden Research Center, US
We have developed polyamide bi-layer thin film composite membranes to enhance RO-desalination performance. The polyamide bi-lyer membrane consists of conventional non-substituted aromatic polyamide under-layer and HFA-substituted aromatic polyamide top-layer, which can be esaily prepared by [...]
Computer modeling of water and salt transport in RO membrane active layers
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 [...]
Preparation and characterization of polyaniline nanofiber and nanocomposites and their applications in removal of Cr(VI) and phosphate
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 [...]
Dairy CAFO Wastewater, Water Harvesting and Ammonia Fuel Cells
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 [...]
Testing a Geochemical Tool to Enhance Our Ability to Ensure Water Security
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 [...]
