In recent years, the possible applications for double-walled carbon nanotubes have excited scientists and engineers, particularly those working on developing renewable energy technologies. These tiny tubes, just two carbon atoms thick, are thin enoug... [more]

A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a new article.... [more]

The first generation of quantum dots were made from the toxic heavy metal cadmium and had emission wavelengths, and colors, determined by their size. Lattice strain created by layers of different semiconductor materials allows the color of quantum ... [more]

Ultra-thin and energy efficient displays that use organic compounds to emit light have been stirring up excitement in the consumer electronics industry for several years. Researchers have now developed a cost-effective method for manufacturing flexib... [more]

The push for alternative energy has created a large demand for corn stover, a popular feedstock used to produce cellulosic ethanol, but utilizing these materials, rather than using it as compost, means a loss of soil organic carbon. Researchers have ... [more]

A new study suggests that evolution can behave as differently as dogs and cats. While the dogs depend on an energy-efficient style of four-footed running over long distances to catch their prey, cats seem to have evolved a profoundly inefficient gait... [more]

Deep cuts in carbon dioxide emissions consistent with the UK's 80% greenhouse gas emission reduction target by 2050 are technologically and economically feasible. However, these cuts will require fundamental shifts in technology and behavior. Much mo... [more]

As most American families sit down to Thanksgiving dinner, a University of British Columbia researcher is revealing how one of the largest animals on earth feasts on the smallest of prey -- and at what cost.... [more]

The Danish energy system can be changed to depend mainly on renewable energy and cut carbon dioxide emissions by 50%, according to a consensus from scientists, government officials and businesspeople. The big challenge lies in the system itself.... [more]

Reducing friction in industrial machinery can save substantial amounts of energy and researchers are working to develop nanoscale coatings for machine parts that not only reduce friction but extend tool life as well. Estimated energy savings from the... [more]
