vrushali gawari, so glad to be helpful. We appreciate your feedback. If you have other graphene questions we have not answered yet, please make suggestions!
@@NixenePublishing I would like to know about reduced garphene oxide as well. I like this video, it's so interesting , and wonderful knowledgeable. Thank you 😊
@@vrushaligawari9721 Thank you for your suggestion! I will pass it along. Stay tuned - as a subscriber, you'll see our videos before they're distributed on other social media channels.
Most enlightening and excellent 'no~frills' presentation My long~held curiosity now sateable, thanks to you and this channel. Bless you both! 💖 Subbed.

What are the downsides to graphene? Following points summarize Graphene disadvantages: ➨Creation of high quality graphene is expensive and complex process. ➨In order to grow graphene, toxic chemicals are being used at high temperatures. Due to this it exhibits toxic qualities.
Amazing explanation !!!Thank you

Hello again! Did you see the video about Reduced Graphene Oxide? Your question inspired an entire video! ua-cam.com/video/qN0qHq_izto/v-deo.html
Most enlightening and excellent 'no~frills' presentation
My long~held curiosity now sateable, thanks to you and this channel. Bless you both! 💖

How would graphene oxide crystals affect the brain?
Thanks for your video, but can I ask this, GO can be applied as a Lithium ion Battery, right ?
Is it good if we applied as a battery?
Human bodies are mostly water
Mainly empty space
@@darrent2733 well there are likely energies within the fabric of water, and bodies, that though yet remain unseen, do not qualify as 'empty'.
Was this in flu vaccine also?
Maybe in China. Not in the United States.
@Mruuuczek No. I wouldn't.
why on earth would they put random bits of material in a vaccine ?
Yes
Can we use HCl for the synthesis of graphene oxide instead of using sulphuric acid or phosphoric acid..?
Thank you for asking - we will be back to you shortly with the answer!
"A good question, I assume that you use the term HCl to mean Hydrochloric Acid
The short answer is HCl is used more as a processing aid than critical component of the graphene manufacturing process
Longer answer...
Acids are used in two ways in the manufacture of graphene and graphene oxide from graphite (Both are significant commercial production processes for making graphene and graphene oxide powders from graphite)
1. Hummer’s method
Concentrated strong acids and oxidising agents can break apart graphite into graphene oxide. (don't try this at home)
Sulphuric acid (H2SO4) tends to be used in Hummer’s method and HCl is used to wash the graphene oxide to remove impurities and HCl also seems to reduce the graphene oxide back to graphene slightly
You can find out more from this paper:
Synthesis of Graphene Oxide using Modified Hummers Method: Solvent Influence
www.sciencedirect.com/science/article/pii/S1877705817316235
2. The electrochemical exfoliation of graphite to graphene and graphene oxide.
Dilute Sulphuric acid helps the electric current flow through water from one electrode to another made of graphite
The sulphate ion from the acid does the intercalation helping the graphene layers separate into graphene (Exfoliation)
Imagine graphite is like a deck of cards (each of these cards is a layer of graphene)
The electricity helps force apart the cards
The Sulphate ion gets in between the cards (Intercalation) stopping them from sticking back together again
Hydrochloric acid has been tried in this electrochemical method but the Chloride ion doesn’t form as easily as the sulphate ion and chlorine gas is evolved,
This means HCL doesnt help the exfoliation process
A paper has just been published that looks into this in more detail, you can find out more from this link:
Role of anions on electrochemical exfoliation of graphite into graphene in aqueous acids

Correct
Sounds awesome.... Let's inject everyone with it... What's the worst that can happen?
Heart attack brain haemrrage clotting multiple organ failure sudden death based upon amount they act as micro razors inside body
I'm also working on graphene oxide
Can I pllz contact you ,because me too I have the same subject
all cientist are psico??
I would love to meet yay, from Columbia,MS
Turn comment on U TUB E EVERY THING
So ?
