Rice lab makes pristine graphene in a flash

[TrackZero]

You guys cracked it, mass production! Everything's about to change. Excellent work!

NightHawkInLight just did a video on doing this at home. This process is amazing in it's effectiveness and simplicity.

[Shunarjuna]

I really really hope this lives up to the promise.

OMG Duy Luong, this will make History! You will get the Nobel Prize.

"Rice Lab" fits it perfect .... lol

Now graphene is only eternally 14 years away!

[RandyJames]

I've gotta ask -- Could you could put rice in there?

The winds and currents of SE Asia drive all the plastic/rubber thrown into the sea, in SE Asia, into the Gulf of Carpentaria. Cape York Peninsula enjoys huge solar energy resources. Combine the two ... and anything's possible!

okay, so I converted/converting my sailboat to an electric sailboat. I will be adding some amount of capacitors for burst speed (to try to outrun rouge waves) and I feel I could dual-purpose the bank of capacitors for Diy flash graphene. maybe use the motor controller to control the timing. I would like to add it to the epoxy resin as I rebuild and repair the boat.

There is a better path to mass production. I calculated that a 20m radius sphere that is mirrored on the bottom half would reflect enough sunlight to the focal point to heat several kg of rubber (any carbon source would work though) per second to the same temperatures as your flash process. This is assuming a 75% theoretical efficiency (1kw/m2-25%). Since it is a sphere you can pump it down to a vacuum and spray melted/liquid feedstock through the focal point and into a catch pipe. The bottom of the catch pipe can have a double gate to allow continuous removal of graphene.

Another option is to use a mirrored tube, which allows for lower density/slower heating feed stock to be brought to temperature over a longer time. This requires a much larger diameter though because the reflective area is reduced greatly.

This process would be sun powered, so there is very little cost once the sphere is built. Glass is cheap and so is a first surface silver mirror treatment. By adjusting the shape of the sphere slightly you can widen the focal point to account for the volume of the feed stock. This is needed because a perfect parabola would focus too much energy to a small point.

amazing discovery! Could welding machines be turned into production units like this? Just a thought.

[wessonsmithjr.]

It's at this point that Duy Luong's student visa isn't renewed and James Tour takes all the credit for his discovery.

How much electricity would it take to convert 1 ton of coal into how much graphene?

[dragossorin]

Good job, fruits of research always worth a lot and change the world for better

[JohnFerrier]

This is interesting for sure but I'm not convinced of the applicable nature of it. Powdered graphene is great for research. But, how well is the thickness controlled? I sure there's a bit of randomness to it but is there a specific method for controlling that? Otherwise, it's not much different than reorganized graphite.

[roninbadger]

lets see you do this with pressurized gas? co2 or co. use the coal to power a plant, use the output and exhaust for graphene.

[xddelectronics]

1:28 look's like sun shine actually grapheshine :o

[juanfranco]

I have a doubt.. If you put pure black carbon inside the quartz tube and give it one discharge, how much of this carbon is turned into graphene? Thanks! Great work!!

[muhammadomer]

Can this process be done by using concentrated sunlight heat ?
