Survival water filters.  Now that is useful.

I've read that hraphene is harder than diamond.  I wonder if body armor would b a practical application?

Football helmets?

I thought the main envisioned use for graphene was for semiconductors to keep on that Moore's Law schedule.

Thank you, Marty.  Now, if I had some decent coffee I might go back and re-read all this fascinating information.

While I'm tempted to resurrect that one too, I'll resist the temptation because it's game day and I would be treading on "dangerous grounds."  :-\

This is why I stopped doing undergrad admission interviews for Stanford--it was too depressing seeing so many bright kids (many of whom surely had better resumes than I did as a high school senior) get rejected.

I wish it had.

But when you realized it wasn't about coffee you said to yourself, "Self!  This would be perfect for the Intrigued By Graphene" thread!  At least ferrari will comment!  Let's do this!"

Is this Shaw's fault, too?  I'm not getting the drift here.

I don't really understand why GG posted it, but it made me very underwhelmed by local sushi spot.

Thanks for nothing garvin.

No.  Common wisdom is its Bush's fault.  Along with the drought.

Well, since the drought is also partially Bush's fault, we can simplify things by just going with it is all Bush's fault.  ;)

You all missed the point.  After his TV show Dangerous Grounds was cancelled (which is a mystery to me), Todd has a new show on the Travel Channel called "Uncommon Grounds."

Just because... the Economist's technology quarterly featured a special on materials science, including the following passage on our old friend graphene:

Quote:At this scale, problems such as power leakages and instability start to crop up. One day silicon may well make way for other materials that promise superior electrical properties, such as gallium arsenide, titanium trisulphide or possibly graphene.
Unclaimed treasure
Much hyped as a “wonder material”, graphene is a form of carbon discovered in 2004 at Manchester University in Britain by Andre Geim and Kostya Novoselov, who won the Nobel prize in physics for their work. It is one of a number of two-dimensional materials, so called because they are only an atom or so thick. Lots of researchers and startups have moved into graphene because it is extremely light yet strong; it is transparent; and it can be made to work as a semiconductor. So far, though, most graphene is used in research labs, which are still looking for a “killer app”. Beside computer chips, potential uses might include membranes for water purification, more efficient solar cells and invisible electrodes in glass. Meanwhile, though, carbon in other forms is already big business in two of the world’s largest manufacturing industries.

You can read the whole thing to find out what other materials you should be intrigued about.

The ships were slow and much too inefficient for peace time work and many were purposefully sunk to form breakwaters and reefs after the wars.  This world war I era derelict is still in place south of Santa Cruz at Seacliff beach in Aptos.

Thanks for illuminating us regarding Graphene and for the trip down memory lane regarding the cement boat.  As a kid growing up in Aptos/Santa Cruz, I caught my first fish off that boat with my father!  He told me that when it was first docked/sunk at that location it was turned into a night club with some concerts and dances that hosted some jazz greats over the years.  I'm fairly certain that was before Santa Cruz had true harbor.

I spent my high school years (late 1970s) in Santa Cruz, and for ten years before that, my grandfather would rent a beach house for two weeks for all of us every summer.  I've been out on that boat probably 1/2 dozen times.  Good times.

Re: Intrigued by Graphene - BostonCard - 08-09-2016

At the risk of reviving the thread that won't die, I found this article about everyone's favorite carbon compound:

http://www.economist.com/news/science-and-technology/21704743-world-moves-step-closer-graphene-based-electronics-obstacles?fsrc=scn%2Ftw%2Fte%2Fbl%2Fed%2F

Quote:SINCE its discovery in 2004 graphene, a form of carbon made of sheets a single atom thick, has been an invention in search of an application. In particular, it has fired engineers’ imaginations with the possibility of making thin, flexible, semi-transparent electronics. But it has always promised more than it has delivered because, though an excellent conductor of electricity, its other electronic properties are lacklustre. First, instead of being easily channelled, electric current moves across a graphene sheet randomly and in all directions. Second, graphene does not have a bandgap—a property needed to create the distinct “on” and “off” electronic states that transistors rely on to work, and which is induced in a material by disrupting the way its electrons are distributed.

Sounds like some significant challenges in this attempt to make graphene useful.  But you never know...
