 Washington DC (SPX) Aug 03, 2009 
With a sustained national commitment, the United States could obtain substantial energy-efficiency improvements, new sources of energy, and reductions in greenhouse gas emissions through the accelerated deployment of existing and emerging energy technologies, according to America's Energy Future: Technology And Transformation, the capstone report of the America's Energy Future project of ... read more 
Carbondale IL (SPX) Aug 03, 2009A researcher at Southern Illinois University Carbondale is working with the Canadian oil and gas industry to take land reclamation to a higher level. Dale Vitt, professor and chair of the Department of Plant Biology in the College of Science, is working with Syncrude, a joint venture of oil and gas companies mining the oil sands in Alberta. The project - part experimental research, part ... more

New York NY (SPX) Aug 03, 2009At first glance, the light-emitting diode, or LED, beats the venerable incandescent bulb in every way. It's compact, bright, long-lasting, and in its latest form it can produce a warm, white light. Best of all, it saves more than enough money on electricity to cover the extra cost. But the LED is bedeviled by a problem known as droop, which kicks in just as the power levels begin to get high enough for general lighting. ... more 
Amherst MA (SPX) Aug 03, 2009In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than ... more 
Atlanta GA (SPX) Aug 03, 2009Recent research into the properties of graphene nanoribbons provides two new reasons for using the material as interconnects in future computer chips. In widths as narrow as 16 nanometers, graphene has a current carrying capacity approximately a thousand times greater than copper - while providing improved thermal conductivity. The current-carrying and heat-transfer measurements were ... more |

Fayetteville AR (SPX) Aug 03, 2009Electrical engineering researchers at the University of Arkansas and the University of South Carolina were informed this week that they will receive federal economic stimulus funds via the National Science Foundation to continue and strengthen their efforts to modernize the national power grid. The award will establish an NSF center of excellence, known as an Industry/University Cooperative Rese ... more 
Cambridge, UK (SPX) Aug 03, 2009A team of physicists from the Universities of Cambridge and Birmingham have shown that electrons in narrow wires can divide into two new particles called spinons and a holons. The electron is a fundamental building block of nature and is indivisible in isolation, yet a new experiment has shown that electrons, if crowded into narrow wires, are seen to split apart. The electron is ... more  
Cholpon-Ata, Kyrgyzstan (AFP) July 31, 2009The presidents of seven ex-Soviet states were to meet Friday for a summit of a security grouping led by Russia and touted as an eastern counterweight to NATO. But the meeting at an idyllic location on the shores of Lake Issyk Kul in Kyrgyzstan was set to be marked by differences as Moscow struggles to keep control over its former Soviet subjects. The leaders of the Collective Security Tr ... more |
