Wonder Paper Shows Antibacterial Promise

- Today in the news - 30 years have passed since graphene was introduced into food packaging, now research suggests that graphene causes impotence and micropenis to develop in the fetus.

[citation][nom]Arethel[/nom]Oh thank you!Yea I was wondering if this was the case looking at the structure of graphene. So then it does only act on a plane...Say do you know if carbon coating is possible as a post machining process? At my last company, we used to send out a lot of parts to get coated for use as sputtering targets and for hot isostatic press.[/citation]
Yeah, the real world thermal conductivity of pyrolytic graphite (which is stacked sheets of graphene) is 6-7 W/m-K in the Z axis, but along the x-y plane the real world conductivity can be anywhere from 600 to 1000 W/m-K. The theoretical z-axis of graphene is supposed to be 500-600 and the x-y is supposed to be 5000-6000 (even higher than diamond at 2000) according to some white papers I've read but a single atom thick material isn't terribly practical and when its turned into stacked sheets (pyrolytic) the final numbers decrease significantly.

It is possible to coat post production parts, highly oriented pyrolytic/graphene coated systems are typically created using a CVD (chemical vapor deposition) process. CVD is the only method I'm personally familiar with for carbon coating, but I'm sure there are some other electrostatic or sputter methods out there (I just don't have any experience with them). We also use some graphite inks to screen test pads on some of our materials, but I don't really consider that a refined coating process.

Since its being researched in China. Does that mean they will all lead to it before shipping it to the states?

[citation][nom]wawa sxm[/nom]what worries me is that we are introducing all this nano technology and dont know the effects on humans....its so small we must be breathing more and more nano particles and it has to go somewhere....[/citation]
straight out ur butt with the rest of the feces.

^ which goes into the toilet (hopefully), and cleans all system from there on... there will be no need for water filter.

What? Oh, I'm sorry, I was looking at that bird over there...

Yeah.. possibly the next triclosan... supposedly a miracle anti-bacterial compound that inhibited bacteria cells.. but under long term use does that to human metabolism in cells too-- go figure. Since skin is very regenerative that wasn't an issue in NORMAL HEALTHY ADULTS.. but CHILDREN and the IMMUNE (elderly or other conditioned people) COMPROMISED... another story completely.

Where are our supercomputers to run these long-term projections?
Nobody's programming long-term worst case scenarios on these new materials they're inventing (aka cooking up) in the labs.
