Among Many Uses Gold Nanoparticles Could Help Dye Sensitized Solar Cells

Gold nanoparticles could be used to make better Graetzel solar cells, among others, as a Queensland University of Technology scientist claims to have discovered.
The scientist is Adrian Fuchs, and he found out how gold nanoparticles can be dispersed into polymers or plastics, to make them more durable.
They could also be used in intensifying the colors of dyes: "Paint is essentially plastic so when gold nanoparticles are added it makes colours more intense across the whole visible spectrum.The paint also be more durable when exposed to a harsh environment."
The interesting part for us it that "if you put gold nanoparticles with titanium dioxide using a plastic mould, you can make every efficient catalyst to purify water: the titania absorbs the light and converts it into elctricity which is passed into the conductive gold."
Today's Graetzel (dye-sensitized solar cells) are very inefficient but cheap. Making better conducting layers for them wold accont for an increase in efficiency, which more than expected. You may think that if gold is involved in this process it may bring the prices up from where they were, but Fuchs only studies a gold nanoparticles approach, so i think high prices are out of the question here.

Instead of gasoline - bioaccumulative

The United States consumes daily vehicles over 7 million barrels of gasoline - a figure that explains perfectly why we need to find a solution as soon as organic for reducing science experiments fuel.
Scientists first powered engines and electric cars water, but could be a viable solution and so-called lithium-air battery.Called top invention of many metal-based batteries is extremely safe and environmentally sound.
Studies, yet in its infancy, already show that the battery is able to store nearly as much energy as a gasoline tank, so basically there are all prerequisites for a new enviromentally friendly vehicle.
