For years, scientists have dealt with the problem of trying to increase the efficiency and drive down the cost of solar cells. Now researchers have hit upon a new idea—trying to give the light collected by solar cells a bit of “amnesia.”
Energy prices and environmental concerns are driving the United States to rethink its energy mix and to develop domestic sources of clean, renewable energy.
This spring, officials at Chicago’s Department of Public Health (CPDH) watched the H5N1 bird flu tear through neighborhoods, taking down public agencies and shuttering public schools. Good thing it was just a drill.
Last month, the U.S. Department of Energy (DOE) announced a multi-institutional effort composed of leading scientists from several institutions, including Argonne National Laboratory.
More affordable and efficient solar cells, batteries and lighting systems could result from a new X-ray lens that will let scientists study the nanoscale in greater detail than ever before.
