CAMBRIDGE, Mass., Aug. 10, 2010 — A new silicon material has been produced that actually melts as it cools off, which could lead to applications in solar cells and other devices. A tiny silicon chip — the glowing orange square at the center of this special heating device...

MENLO PARK, Calif., June 30, 2010 — The world’s brightest x-ray source has been used to strip neon atoms of all their electrons, and also to create "hollow" atoms, which are devoid of only their innermost electrons. The first published scientific results from the hard x-ray...

ARGONNE, Ill., June 16, 2010 — Using silver chloride nanowires decorated with gold nanoparticles, a scientist at the US Department of Energy’s (DoE) Argonne National Laboratory has created visible-light catalysis that may decompose organic molecules in polluted water. ...

ANN ARBOR, Mich. – Light can bend rigid structures, at least on a microscopic scale, researchers report. Light-driven twisting of tiny ribbons could someday be used for negative refractive index materials, in microelectromechanical systems (MEMS), or for lithography...

BERKELEY, Calif. – Researchers have shown that they can control matter directly with intense x-ray beams and can use one beam to control another. The experiments could open the door to new and interesting ways to use x-rays, said Thornton E. “Ernie” Glover...

May 10, 2010 — Researchers anticipate that the world’s energy needs will double by 2050. To help meet these ballooning needs, the US Department of Energy (DoE)’s Argonne National Laboratory in Illinois recently launched an Alternative Energy &...

BERKELEY, Calif. May 7, 2010 — Scientists working at beamline 9.0.1 of the Advanced Light Source (ALS) at the US Department of Energy’s Lawrence Berkeley National Laboratory have used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest...

BERKELEY, Calif., March 29, 2010 — By changing the material medium through which x-rays pass, scientists are using laser light to control x-ray beams. The team of scientists was led by Thornton E. Glover of Lawrence Berkeley National Laboratory’s Advanced Light Source (ALS),...

ST. LOUIS, March 24, 2010 – The National Science Foundation has awarded $1.65 million to a project led by physicist Ken Kelton of Washington University in St. Louis to build an electrostatic levitation chambe...

BERKELEY, Calif., August 1, 2008 – For the first time, scientists have discovered a way to perform high-resolution x-ray diffraction imaging of an aerogel. Sometimes referred to as “frozen smoke,” aerogels are solid nanoscale foams with a sponge-like structures that are riddled by...

Jan 1, 2008 — Much progress is being made in using electromagnetic radiation at terahertz frequencies for noninvasive detection and pharmaceutical testing applications, among others. Current technologies, however, limit generation and detection of the frequencies...

Oct 26, 2007 — Physicist Walter F. Henning of Argonne National Laboratory in Argonne, Ill., was awarded a Cross of Merit of the First Class of the Federal Republic of Germany by German President Horst Köhler at a ceremony this month in Berlin. Argonne National...
