Breaking Kasha's Rule

Image Ames Laboratory researcher Sanjeevi Sivasankar was part of a team at Berkeley National Laboratory that created artificial molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as “Kasha’s rule.”

AMES LABORATORY’S GORDON RECEIVES ACS COMPUTING AWARD

AMES, Iowa –Mark S. Gordon, a senior scientist at the U.S. Department of Energy’s Ames Laboratory, has been named the recipient of the 2009 American Chemical Society Award for Computers in Chemical and Pharmaceutical Research. The international award recognizes outstanding achievement in the use of computers in research, development or education in the chemical and biological sciences.

AMES LABORATORY’S GSCHNEIDNER RECEIVES ACTA MATERIALIA GOLD MEDAL

AMES, Iowa – Karl A. Gschneidner, Jr., senior metallurgist at the U.S. Department of Energy’s Ames Laboratory, has been awarded the prestigious Acta Materialia Gold Medal, considered by many scientists and engineers to be the top award worldwide in the field of materials research. Gschneidner received the award during the 2008 annual meeting of The Minerals, Metals & Materials Society in New Orleans, La. on March 11, 2008, where Ames Lab senior metallurgist Iver Anderson was honored also with a TMS Distinguished Scientist/Engineer award.

MIDDLE SCHOOL SCIENCE TEACHERS RETURN TO AMES LABORATORY

AMES, Iowa - The U.S. Department of Energy's Ames Laboratory is making science exciting this summer for eight science teachers from middle schools across the Midwest.  These dedicated and motivated teachers are participating in their second year of the Laboratory's Academies Creating Teacher Scientists, or ACTS, program.  ACTS began on June 23 and runs through July 25, 2008.  This year the teachers had the added bonus of visiting both the DOE's Argonne and Fermi national laboratories, where they toured facilities and met with scientists and teachers participating in the ACTS program in Illinois.

AMES LAB SHOWS 3-D PHOTONIC CRYSTALS MAKE NOVEL ADD-DROP FILTERS

AMES, Iowa – Researchers at the U.S. Department of Energy’s Ames Laboratory have come up with a potentially perfect way to sort and distribute the massive amounts of data that travel daily over optical fibers to people throughout the world. The new technology, a three-dimensional photonic crystal add-drop filter, promises greatly enhanced transmission of multiple wavelength channels (wavelengths of light) traveling along the same optical fiber. The innovative filter is a significant achievement in the effort to develop all-optical transport networks that would eliminate electrical components from optical transmission links and guarantee virtually flawless data reception to end users of the Internet and other fiber-based telecommunications systems.
