"Decorators will soon be charging more"
That is truly awful.
I'll get your coat (of paint). And mine please.
Boffins in America have developed a "one-dimensional" nanomaterial liquid which can be painted onto walls or pieces of paper to create working batteries. "If I want to paint my wall with a conducting energy storage device, I can use a brush," says Yi Cui, materials engineering prof at Stanford. "These nanomaterials are …
Just like black-powder.
The smaller the particle the quicker to discharge, and charge, though overall capacity may be the same it doesn't last as long.
Sounds good, especially interesting is the places where this can be applied when compared with a normal battery.
Though I find it hard to believe that the description of 'one-dimension' can be taken seriously.
PH - cos her personality's more likely to be one dimensional, though her physical side is clearly operating in all 4 (easily) observable dimensions.
is 3 dimensional, with the possible exception of some people I have met. That must be a translation error for nano-scale flat. I am sure it has at least the height, depth, and width of an electron...
I'll be painting some on me pint to keep the unwanted hands off of it..
One-dimensional? Then it truly is the most remarkable invention of all time! An imaginary mathematical construct made real! Anything one-dimensional would have zero mass and, of course, it would be invisible. You could stack an infinite number of them in your shirt pocket.
The world's energy problems have been solved!
One-dimensional is a mathematical construction used for theorizing.
As Mike61 pointed out, there is nothing one-dimensional in the real world. Paper may only be a hundredth of a an inch thick, but one- and two-dimensional mathematical figures have NO thickness whatsoever - thus they can only exist in mathematical constructions.
Of course, something that is only a few nanometers thick is probably the best real-life approximation of one-dimensional we'll ever get, but by the way they pasted the nano-battery material on the paper, I doubt that the material is that thin.
