An Ab Initio Study of CuGaSe2 (001) Surface

Chew S., Liborio L., Harrison N., Imperial College London, UK

The chalcopyrite material CuIn1-xGaxSe2 makes one of the best performing devices for thin film solar cells. Despite this, there is still a lack of understanding of some of the fundamental properties of the material. CuGaSe2 [...]

Multi Solar Desalination Plant

Elazari A., Millennium Electric T.O.U. LTD., IL

Desalination technology, which makes it possible to exploit sea water as a water source, is playing an increasingly important role throughout the world. However, its high energy consumption is costly (4-5kWh/1 cubic meter of desalinated [...]

Sustainable and cost effective solar technology made from Tetrapod Quantum Dot Solar Cells

Glass R.A., Squires S., Solterra Renewable Technologies, Inc, US

Solterra Renewable Technologies Inc is designing and manufacturing solar cells using a proprietary thin film semiconductor technology that will allow a reduction in the average solar cell manufacturing costs and be extremely competitive. Solterra will [...]

Use of Solar Energy in the Automotive Sector

Van Oyen H., Quantum Technologies, Inc., US

With the advent of more Plug-in Hybrid Electric Vehicles (PHEV) on the market, the use and integration of solar electric components in this sector is becoming larger. Two areas of providing electrical energy into a [...]

High-Performance dye-sensitized solar cells with various nanostructured materials as counter electrode

Ouyang J., National University of Singapore, SG

Traditionally, Pt prepared by hydrolysis was used as the counter electrode of dye-sensitized solar cells. But the hydrolysis requires a high-temperature process, so that it is not suitable for flexible substrates like plastics. In addition, [...]

Greening and Growing the Grid: Utility-Scale Solar 101

Alcombright D., SOLON Corporation, US

With the growth of renewable portfolio standards, rising electricity rates and increasing peak load demands, U.S. utilities are seeking new solutions to meet their renewable energy needs. Scalability, cost and reliability have been the primary [...]

The influence of surface termination on growth of cupper clusters

Xiao L., Srinivasan J., Subramanian L., Accelrys Inc., US

Oxide supported transition metal catalysts are widely used in variety of heterogeneous catalytic processes. Knowledge of the interaction of metals with oxide surfaces provides insight into understanding a broad variety of properties of the catalysts. [...]

High-temperature Desulfurization with Nanosize ZnO

Wang H.P., Wang T.C., Kang H.Y., Wang H.P., Wang T.C., Jou J.G., Wei J.L., National Cheng Kung University, TW

Thermal efficiencies of an integrated gasification combined cycle (IGCC) process can be enhanced with high-temperature desulfurization. Nanosize, sub-nano (clusters) and atomic-dispersed ZnO has been prepared for the high-temperature desulfurization. An enhanced absorbance of the nanosize [...]

Nanoparticles: Promising Solution to Overcome Stern Drilling Problems

Abdo J., Danish M., Sultan Qaboos University, Oman, OM

General solution to overcome stern and frequently occurring drilling problems lies in controlling the rheology of drilling fluids. Pipe sticking, lost circulation, erosion, formation damage, thermal instability, poor hole cleaning, high torque and drag are [...]

Microkinetic Study of Oxygenate and Hydrocarbon Formation from Syngas on Rhodium and Cobalt Surfaces: Effect of Site Structure on Catalytic Cycles

Kapur N., Sampara C., Hao X., Hyun J., Shan B., Nicholas J.B., Davis B., Cho K., Nanostellar Inc., US

Syngas reformation into fuels is an attractive opportunity to diversify away from petroleum and address energy-dependency concerns. Rh and Co-based catalysts used within Fischer-Tropsch (FT) process selectively convert syngas into oxygenates and hydrocarbons respectively but [...]
