Nice find.    I wonder if you could combine a graphene super capacitor with a Jule Thief circuit.

Does anyone know, what does the chemical reaction in this video? can anyone translate, what`s spoken/written?

Anyone?
Any idea what could make this reaction? Looks like exothermic reaction.... could this be something like the thing in the draincleaner with (the metalic looking spots) aluminum and water?
 
Or does anyone know, how to make (easy way) "Graphite oxide"?

Thanks!

Hello

Heat up graphiteoxide :

Thanks for the response!

My Question is, how to make  "Graphite OXIDE" , because this is the start material to get to Graphene :)   .... the description in the video you posted is :"Graphite oxide exfoliation at ~350 degrees C. About 30 mg of graphite oxide loaded into furnace heated to 380C and in two minutes it explodes into fine carbon powder. Reaction occurs with impressive increase in volume."

So, does anyone know, how to get the OXIDE state of Graphite?

From this we can start to get on experimenting and build Graphene......

The main goal is now to get a easy way to produce  OXIDE state of GRAPHITE.....

THANKS :)

A while ago I made a post here perhaps it's relative now.

Producing large amounts of graphene is not very difficult using an electrochemical method with sulfuric acid:

It's much harder to make long strings of graphene, which would have much more applications.

This kind of graphene already has many potential applications one of which is cleaning up oil spills, quickly, safely, cheaply:

This can be even produced on demand on a ship, and not only is it completely non toxic, the oil can even be retrieved simply by burning it. Makes you wonder why oil spills still are being cleaned by very toxic and dangerous oil dispersants.

Thanks for the support!

Here maybe something of interest:

Anyone who knows, or has any idea how it is made, please let us know!

The key to all is the liquid chemical that "Victor Petric" has "invented" for the process...

That guy does not reveal a word about those components or technology. I was learning Russian a while ago and I still understand it somewhat. He says only something like: "look, how science is wonderful and especially Russian science."

You can easily find the patents however the magic juice which is the “activated acid catalyst” sounds a bit vague to me.

Quote
As still further used herein, the term “activated acid catalyst” refers to an acidic solution of a compound, wherein the solution (typically, but not necessarily aqueous) is subjected to an electromagnetic field, electromagnetic radiation, and/or laser irradiation. Most preferably, the activated acid catalyst comprises an acidic solution that is plasma-activated and/or comprises a compound having the general formula MXOn, wherein M is selected from the group consisting of H, NH4, Na, and K, wherein X is selected from the group consisting of Cl, Br, and I, and wherein n is an integer between 0 and 4, inclusive. It should be noted that the term “activated acid catalyst” also includes one or more oxidizers (typically, but not necessarily in aqueous solution) that were previously subjected to electromagnetic radiation, an electromagnetic field, and/or laser irradiation. Alternatively, and in less preferred aspects, activation using the electromagnetic radiation, electromagnetic field, and/or laser irradiation may replaced by admixing the acid or oxidizer with a penetration enhancer (e.g., compounds and/or mixtures commonly found in lubricating formulations, etc.).
In one preferred aspect of the inventive subject matter, the inventors discovered graphene can be produced from commercially available graphite (e.g., Natural crystalline flake graphite from Superior Graphite Co., 10 S. Riverside Plaza, Chicago, Ill. 60606) using commercially available activated acid catalyst (e.g., Activated Acid Catalyst #3[Plasma-activated hydrochloric acid] from SupraCarbonic, LLC., 348 N. Eckhoff Street, Orange, Calif. 92868, USA). For example, the crystalline flake graphite is granulated to a size between about 0.1 and several millimeter and mixed with the activated acid catalyst in approximately same weight proportions (e.g., 10 gram graphite with 10 ml activated acid catalyst). The so prepared activated graphite is then subjected to heating at a temperature of about 120° C. for up to two minutes (typically less than 40 seconds) to expansion (up to 500-fold in volume). Exemplary electronmicrographs of the so produced material are depicted in FIG. 1A and FIG. 1B at different magnification.

From this patent:

This explains a new way to make GO.  Then, all we need is a DVD disk and a DVD burner.  It might take some time to figure out the mixture ratio but man, this stuff is the future.

The first thing I would do is to hook it to a JT circuit.

I wonder if we can really make this stuff?

Print your own supercaps!

This is directly related to the dvd burner process.  This is amazing.
