Lab-Made Antennas Are Sun ‘Sponges’
ST. LOUIS, Aug. 27, 2013 — The evolutionary chemical machinery of nature — and a dash of human ingenuity — have created synthetic light-harvesting antennas that convert sunlight into unprecedented amounts of usable energy.
Turning Gold to Purple to Harvest Sunlight
PROVO, Utah, Jan. 31, 2011 — Professor Richard Watt and his chemistry students at Brigham Young University suspected that a common protein could potentially react with sunlight and harvest its energy — similar to what chlorophyll does during photosynthesis. They...
Mimicking nature to build a better solar cell
Dec 1, 2010 — Leaves are nature’s quick-change artists. In summer, dressed in hues of green, they convert sunlight into chlorophyll, take in carbon dioxide and expel oxygen. Come fall – in northern latitudes, anyway – they turn from...
Gold Nanoparticles Advance Bioluminescence
TAINAN, Taiwan, Nov. 8, 2010 — Gold nanoparticles can induce luminescence in leaves, which could lead to more environmentally sound LEDs, researchers in Taiwan report.
Nature’s ’Light Switch’ Decoded
UPTON, N.Y., June 2, 2010 — Scientists at the US Department of Energy’s (DoE) Brookhaven National Laboratory and collaborators at the University of Wisconsin, Madison, have deciphered the structure of a molecular ‘switch’ much like the one plants use to sense...
The road to solar cell supremacy
Oct 1, 2009 — The silicon traditionally used to make solar panels is costly and inefficient at converting sunlight into electricity, experts say, yet it remains the material most commonly used to make solar panels. “This sounds rather ugly, but silicon is the...
Blue Bananas Linked to Cell Death
INNSBRUCK, Austria, & NEW YORK, Sept. 10, 2009 – Bright blue luminescent rings found under UV light on the peels of very ripe bananas hold promise for studying how organisms rid themselves of dying cells, according to chemists in the US and Austria.
Green Bacteria Harvests Light
UNIVERSITY PARK, Pa., May 5, 2009 – The structure of chlorophyll molecules in green bacteria that are responsible for harvesting light energy were determined by an international team of scientists. The discovery could one day be used to build artificial photosynthetic systems, like...
The bluer the banana, the better
Dec 1, 2008 — That’s one conclusion you might come to after reading a study on the breakdown, or catabolization, of chlorophyll – the process that takes place in autumn leaves as they turn from green into reds, yellows and browns. After discovering recently that...
