Soon we can be our own light bulbs. Note the silicon, the polymer, and gold..... Sparklies anyone? "By depositing narrow light-emitting fibers on a silicon substrate patterned with gold electrodes, researchers at Cornell University have created extremely small light sources with dimensions of only a few hundred nanometers. The fibers are made of a polymer that is embedded with light-emitting molecules, which light up when exposed to an electric field. When the researchers apply voltage to the electrodes, the fiber glows orange at different points, much like Christmas lights, says Hector Abruna, a chemistry and chemical-biology professor at Cornell who is one of the project's leaders.

from the Science Daily Link, I find this quite interesting. I wonder what species is used on the outside?
"The central core of the nanorods is an inorganic crystal, but the polymers attached to the outside are organic species. The combination of the inorganic and organic features resulted in a hybrid structure that proved to be critical to the study. " .....
Organic Polymers? Okayyyyyyyyyyy!

Clay, polymers and organic species: "Sol-gel hybrids The main alternative to the clay route for the formation of organic-inorganic hybrids is the sol- gel process. This is a low temperature route to inorganic oxides and glasses, which involves the hydrolysis and condensation of precursor molecules, typically alkoxides. The reaction proceeds via formation of a sol, which subsequently gels, hence the name. The fact that this process occurs at temperatures between ambient and about 200°C makes it possible to form a vast array of hybrids of oxides such as silica, alumina and titania with organic species ranging from polymers to small organic molecules to bacteria (Figure 1). The products can also be produced in a variety of physical forms, including coatings, monoliths, fibres and nanoparticles. The many potential applications of such sol-gel hybrids include speciality coatings, structural materials, active glasses, sensors, biomaterials, catalysts and so on. An article of this nature can barely scratch the surface of this vast topic, so the versatility of sol-gel science will be illustrated with reference to only two areas, viz. sensors and biomimetics.

Then there are nanocoils so we can't tell the difference between real natural flagellas and synthetic ones, amazing....... Researchers have developed a novel form of propulsion for microrobots that mimics the way bacteria zip about using corkscrew-like appendages called flagella. Tests show that the tiny rotating nanocoils--just 27 nanometers thick and 40 micrometers long--are capable of spinning at 60 revolutions per minute and that it is possible to propel an object at nearly 5 micrometers per second."....... www.technologyreview.com/Nanotech/18532/Skytroll

Such an interesting line of thought, gollum dust and gold rings. Reminds you of the lord of the rings doesn't it. I've been reading the books, only on the second chapter of the first book and a few things I've noticed. Gollum the hobbit type being that killed for the ring of power and can't remember his name or who he was, kind of like soul shattering. Didn't someone say that about morgs? Most that get this affliction loose everything and everyone, a bit similar. What of his eyes flashing with a green flame. The story starts with Bilbo Baggins on his 111 birthday where he invited 12 dozen folks, that would be 144. And here is a link to the dark one of the movie, lots to see here especially if you've been reading my posts and making connections: en.wikipedia.org/wiki/SauronDoesn't what happened in the movie remind you of our world, quickly being destroyed by industry. I love the green myself, the living green world that we were blessed with. So much to see in this world if one will only open their eyes. And what of the all seeing tower, remind you of anything?
