what is the most recent development in nanotechnology?

Answer 1

not the most recent, the most potential for importance.

nano crystals of Titanium Dioxide. They are so small 100 of them fit along one side of a toner particle.

Why are they important? The latest flavor of photoelectric generator used an organic dye bonded to a TiO2 crystal

Present devices, called GRETZEL CELLS, have very low efficiency in full sunlight because you only get one electron per crystal. Then it takes many femtoseconds to reset before another electron can be produced.

Nanocrystals give a breakthrough improvement in the number of crystals, thus more AMPS in a given area.

Horray..

Answer 2

I'll answer that question with a diatribe:

Unfortunately, when Clinton provided research funding for nanotechnology, the definition of nanotech was vague and anyone and everyone in materials sciences started calling their work nanotech. So what we are getting is lots of things like coatings and treatments instead of things like micromachines. Too bad.

Answer 3

Hi. I just read about a sprocket that was turned by harnessing bacteria. Also read about a carbon nano-tube that was used to compress metal within it's structure.

Answer 4

Metameterials!!!

They have been found to accelerate lightwaves around the materials so that that it appears invisible. Unfortunatly, no one has figured out how to do it in the visible light spectrum, on in the microwave spectrum.

Answer 5

One of my favorites is the field effect display made from carbon nanotubes

Answer 6

yea nanotubes are really cool, its like kevlar/carbon fiber in thats its made molecularly from carbon but its much lighter and stronger than kevlar because instead of fibers its tubes of carbon atoms.

Answer 7

Nonotubes or nanowires...
