/sci/ - Science & Math

I've been accepted to do a physics degree starting this September, what am I getting myself into for the next four years? Any advice?

>self repairs when exposed to loose carbon atoms
>more conductive than copper
>one molocule thick
>easy to make
>harder than diamond
>flexible
>transparent
>ultra light
Why havent we started mass producing this shit yet?

Nanotechnology as such, especially graphene comes to mind out of the recent nano discoveries. I think that it will be a game-changing factor as far as technology is concerned.

Hey /sci/, I was planning on making graphene based on the new dvd laser oxidation method of making it. Here are my materials:
-Pure Graphite Powder
-HCl
-KMnO4
(and some additional materials not specifically used for making the graphene):
-Fine Al Powder
-Fine Fe3O4 powder

Any ideas of what I should do for experimentation once I make it? Anyone have any experience making graphene? Anything else that I can do with these materials (besides make thermite; I already did that)?

So what can /sci/ tell me about graphene?

>not taking into account the structure of graphene

Is someone here well read about graphene?

I'm just wondering if it's true something that one of my teachers said, that it would be used in light-based circuits since it could block or let light through by applying a certain electric current to it, though there was still the problem of finding a light source that was small enough.

Because graphene.

Saw this in another thread: "Graphene - The Perfect Water Filter"
http://www.extremetech.com/extreme/115909-graphene-the-perfect-water-filter

... then, read some comments on various messageboards and some people claim that 100% pure water is harmful to humans, or, at least, not healthy.

Sounds like FUD to me... Regardless of whether or not the graphene filter claim is true, is drinking pure H2O healthy?

GRAPHENE ITS THE FUTURE!!!

http://en.wikipedia.org/wiki/Graphene

why am i just hearing about this now?
and why hasn't this started being implemented on mass-scale?

some things that sparked my interest;

>Measurements have shown that graphene has a breaking strength 200 times greater than steel
>'Not only is it lighter, stronger, harder and more flexible than steel, it is also a recyclable and sustainably manufacturable product that is eco-friendly and cost effective in its use.'
>In 2008, the smallest transistor so far, one atom thick, 10 atoms wide was made of graphene.
>In June 2011, IBM researchers announced that they had succeeded in creating the first graphene-based integrated circuit, a broadband radio mixer. The circuit handled frequencies up to 10 GHz, and its performance was unaffected by temperatures up to 127 degrees Celsius.

sounds like this stuff could change the engineering world as we know it
