ID’ing Molecules from the Briny Deep
ABERDEEN, UK, and ZURICH, Switzerland, Aug. 11, 2010 — In a pioneering research project, scientists at IBM and the University of Aberdeen have collaborated to “see” the structure of a marine compound from the deepest place on the Earth using an atomic force microscope (AFM). The results of...
Laser-Triggered Nanoblasts Treat Cells
ATLANTA, Ga., July 29, 2010 — Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells. A field of human...
UV Light Fills in RNA Gaps
ATLANTA, Ga., June 15, 2010 — For scientists attempting to understand how the building blocks of RNA originated on Earth, guanine, the G in the four-letter code of life, has proven to be a particular challenge. While the other three bases of RNA — adenine (A), cytosine (C)...
Letters to the Editor
Jan 4, 2010 — A question on energy I was pleased to see the GreenLight article “Making energy personal” (October, p. 35) on photocatalytic water conversion. In my opinion, this is the only lo...
A New World of Fiber Sensors
Oct 1, 2009 — Optical fiber is well-known for its ability to carry information at high speeds over long distances. Twenty years after the first transatlantic fiber optic cable was laid, these strands of ultrapure glass continue to offer unrivaled bandwidths. They...
Making energy personal
Oct 1, 2009 — A plan sketched out on the back of a paper placemat may one day result in portable, personal power. It all began when Arunas A. Chesonis invited MIT professor Daniel G. Nocera to lunch and asked him what he would do with $10 million from the...
The Main Extraction: Helium Production in the US
Oct 14, 2008 — Helium, especially highly purified versions, has been increasingly in demand globally for its usefulness in high tech applications. Here is a brief history of helium production in the US.
Photolysis Extracts Hydrogen
VICTORIA, Australia, Aug. 26, 2008 – Hydrogen is the most plentiful gas in the universe and having only one proton, it is the simplest element known to man. As a gas, hydrogen is lighter than air and rises into the atmosphere, which is why it is only found as a compound form with other...
Make Like a Plant
CAMBRIDGE, Mass., June 25, 2008 -- Guess you could say that researchers at the Massachusetts Institute of Technology (MIT) have themselves a bit of plant envy. This particular group of researchers is focused on harnessing energy from the sun because they are adament that it is the...
New Superconductors Sought
LOS ALAMOS, N.M., Dec. 21, 2007 -- Fifty years after the Nobel-prize winning explanation of how superconductors work, a research team is suggesting another mechanism for the still-mysterious phenomenon. In a review published this week in Nature, researchers from Los Alamos...
EUV Lithography Improved
CHAMPAIGN, Ill., Sept. 12, 2007 -- Light has been generated and optics damage lessened in extreme ultraviolet lithography by adding a lighter gas to plasma. The microelectronics lithography method is considered a candidate for creating a new generation of smaller, more powerful...
Radoslav Adzic Receives Electrochemical Society Award
May 7, 2007 — Radoslav Adzic, a senior chemist at the US Department of Energy’s (DoE) Brookhaven National Laboratory in Upton, N.Y., has been named the recipient of the 2007 Research Award of the Electrochemical Society (ECS), Energy Technology Div. The award...
Magnetic Polymers May Advance Spintronics
ARGONNE, Ill., Dec. 20, 2006 -- Researchers have pioneered a new approach for making magnetic polymers that are held together with very strong hydrogen bonds and that contain an innovative bifluoride that allows a magnetically ordered state to be obtained. The development may help...
Molecule Camera Images Hydrogen
HEIDELBERG, Germany, Nov. 9, 2006 -- Using intensive, ultrashort laser pulses and compiling a film from the separate images, German researchers have "photographed" the smallest and fastest molecule -- hydrogen. The method allows them to visualize the quantum mechanical wave pattern of...
New Telescope Findings Shake Up Galaxy Formation Theories
BOULDER, Colo., Aug. 15, 2006 -- A heavy form of hydrogen created just moments after the Big Bang has been found to exist in larger quantities than expected in the Milky Way, a finding that could radically alter theories about star and galaxy formation, according to a new...
New Imaging Method Uses Helium Atoms
EUGENE, Ore., Aug. 1, 2006 -- A newly devised nozzle fitted with a pinhole-sized capillary has allowed researchers to distribute helium atoms with x-ray-like waves on randomly shaped surfaces. The technique could power the development of a new microscope for nanotechnology,...
IR Radiation Breaks Si-H Vibrational Stretch Mode
Jul 1, 2006 — Scientists from the University of Minnesota in Minneapolis and from Vanderbilt University in Nashville and Oak Ridge National Laboratory, both in Tennessee, have achieved the room-temperature photodesorption of hydrogen from a Si(111) surface using...
Alternative Studied for Sensitizing TiO
2
to Visible Light
Apr 1, 2006 — To truly enable a transition to a global industrial system based on hydrogen rather than on fossil fuels will require the development of an efficient and environmentally friendly means of extracting hydrogen from feedstocks such as water. One...
Engineers Question 'Buckyball' Safety
Dec 9, 2005 — NASHVILLE, Tenn., Dec. 9 -- Buckyballs, pure carbon nanoparticles shaped like soccerballs, have shown promise as components of fuel cells, drug delivery systems and cosmetics that delay aging since their discovery in 1985. But in a newly published...
