Lehigh University’s Energy Research Center is leading an effort to recycle the carbon dioxide produced by fossil fuel power plants while simultaneously helping Mexico increase its use of renewable energy sources and reduce national CO2 emissions.
Since they were first developed a quarter-century ago, carbon nanotubes (CNTs) have impressed scientists with their mechanical strength and stiffness, their optical performance, and their ability to conduct heat and electricity.
Aluminum recycling has become a successful business since its inception a century ago. Nearly a third of the aluminum produced in the United States is made from aluminum scraps that have been recycled in a process—usually remelting—that uses only 5 to 10 percent of the energy it takes to extract aluminum from mined bauxite ore.
In a twist on "survival of the fittest," researchers including biologist Greg Lang have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride.
