The brilliant colors come from microbes that have evolved to thrive in this extreme environment of boiling acid. (This photo is straight from the camera, with no editing. The colors really do look like that. large size)

Synthetic Genomics just finished sampling these waters to try to help unlock their secrets.

And it’s not the first foray. Early in my exploration of nanotechnology, I came across Jonathan Trent and his work with these microbes. He found a peculiar protein that self-assembled in groups of nine into a ring, and then into a sphere, and the spheres would pack together into thin films on a surface. Metals inside the rings could be left behind on a surface when the proteins were boiled off. It seemed like a jump to the future – an ability to create regular arrays of nanoscale structures from the bottom up, long before the semiconductor industry’s top-down approach.

So I wrote in my first article on Transcending Moore’s Law:
“Researchers at NASA Ames are taking self-assembling heat shock proteins from thermophiles and genetically modifying them so that they will deposit a regular array of electrodes with a 17nm spacing. This could be useful for patterned magnetic media in the disk drive industry or electrodes in a polymer solar cell.”

And my interests shifted to the biological bottom-up path to creating complex systems.

Here are a few of the solar cells produced in the polymer lab. They must be contained as they degrade quickly in air.

One of only 4 polymer labs in California (the others being at Berkeley, Stanford, and USC) this is the only polymer lab where undergrad students are allowed to participate. This polymer lab is used to create organic solar cells and organic LEDs. Organic solar cells can be made at room temperature, making them much cheaper to produce than traditional solar cells. Organic LEDs are the future for TVs, cell phones, and pretty much every other display. OLEDs are much brighter and have much more contrast than LCD or plasma screens. The polymer cells and LEDs must be created in a nitrogen rich environment or the organic matter they are created with will degrade quickly (hence the glove boxes).

An electron microscope image of electrochemically grown TiO2 nanotubes. 10,000 times smaller than the width of a human hair, the tubes are filled with organic polymer in a new technique developed at Argonne for "growing" solar cells with the potential to be cheaper than current solar cells.

Question–: whats the conductive polymers used in Dye Sensitized Solar Cells to get the best efficiency?
Whats the types of conductive polymers known till now which give the best efficiency to the dye sensitized solar cells and also the types of Ru(II) used ?
all what i care about is the high efficiency and stability.
i will be very greatful if you can help me…


The answer in the following: (Hint: For answers, no site audit.)

Answer by ronwizfr
Look up the work of Wayne Campbell at Massey University, New Zealand, who has experimented with a wide variety of organic dyes based on porphyrin, and reported solar cell efficiency of 7% and more.

    as always well done great color and detail all the best bob

    One of my fave places in Yellowstone. Aerial shots are the best of these amazing colours! Interesting structure info, too.

    Great photo! DNA is the most interesting computer program that we have found to date. We are at least now starting to "scratch the surface" in decoding it. I think Venter’s work is fascinating and shows much promise. We may find that his greatest impact may be outside of medicine.

    Excellent shot and excellent explanation. When I first saw this I thought you had gone to the Gulf to observe the spill; then I clicked on it and wow. Great experience visiting Yellowstone.

    this is way pretty..

    love the colors

    always an adventure around hot spot super volcanos…. am taking a class in geology right now, was told that the times between geysers at Yellowstone is lengthening, implying new activity….

    Electronic microscopy gives a whole new perspective about things, much beyond what we see on the screen. Great stuff!
