Description: Discussion surrounding the latest news stories and interesting papers involving the cutting edge of Graphene research.
Graphene - a substance composed of pure carbon, with atoms arranged in a regular hexagonal pattern similar to graphite, but in a one-atom thick sheet. It is very light, with a 1-square-meter sheet weighing only 0.77 milligrams. It is an allotrope of carbon whose structure is a single planar sheet of sp2-bonded carbon atoms, that are densely packed in a honeycomb crystal lattice. The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or 'flake' form of graphite consists of many graphene sheets stacked together.

I'm trying to learn about the structure of graphene and the concept of k-parallel keeps popping up. What is it? I am a sophomore btw so the papers on it are still difficult for me to understand. Thank you!
I have been thinking about making some homemade graphene. Does graphite in a blender with dish soap actually work? Or is it just another internet hoax?
I was wondering if anyone has experience with transferring mechanically exfoliated graphene on a densely patterned silicon oxide die? I haven't been getting great yield and it is frustrating. I clean the dies with IPA and acetone, then oxygen plasma, then do my transfer. If anyone has some suggestions for increasing the yield.
TL/DR : Does anyone have a good demo code or blog post showing gathering metrics from Django Graphene GQL queries to Prometheus?
We have a Django Graphene app working, and are gather Prometheus telemetry to monitor our end points. We are leveraging the Django Prometheus Middle Ware and are able to get telemetry and view it via Grafana. This all works and is awesome.
However, we want to be able to add telemetry to our Graphene GraphQL resolvers and object serialization/deserialization. Right now with Django Prometheus we get a single end point for *all of* our graphql calls, which isn't helpful as we are heavily leaning on GQL for client queries, and the metrics don't provide any insight on which resolvers are slow, or what queries are doing on the back end.
We found Graphene-Prometheus middleware which claims to support Django, but it is out of date, doesn't run on Django 3.x, and we could not get it working.
Any pointers appreciated. Thank you.
Hi, I struggle to understand is there a difference between pure graphene (flash graphene) and graphene oxide. As I can see GO is more available. Also many composites researches using GO instead of pure graphene. Is there any difference between them? Do composites with GO and pure graphene have different properties and how big is the difference?
Another question - as I can see in many many researches they use 0.1%-1% of graphene. What if we use 5-10-20% will mechanical properties increase as well or not? Is it about expensiveness of graphene or problems of dispersion of bigger amount of graphene? Or something else?
Graphene Manufacturing Group and global miner Rio Tinto have entered a Joint Development Agreement to commercialize GMG's graphene-aluminum batteries. GMG will receive $6 million AUD, and this is non-dilutive. Rio Tinto is to receive first purchase rights for the batteries.
Kindly read and share my research on the machine learning interatomic potentials for graphene
I'm trying to find a place to purchase pints or quarts of laminating epoxy resin that has graphene in it.
Pristine flake or nanotubes.
Any help will be greatly appreciated.
I love the French machina concept car
Unfortunately economic situation is bad and price of the share on the stock market was divided by 28 42 to 1.45€...
Lot of explanations but the biggest is battery with electric car are much loved and much more implemented in UE
Hydrogène got 22% of hydrogen efficiency and electric cars 45% So companies prefer going to electric car mot Hydrogène solution
I would like to know the price of 1kg of grqphene
The Hopium Machina got a box solution of stockage of the hydrogen of 300kg ! Plus 10kg Hydrogène under 700 bar of pression 1000km of range
I am sure if we use graphene we could got 30kg max and minimum 3000km range
But as far I know graphene is very expensive
Should be a company or a way to produce it at a very cheap price
Any informations on this great technology price ?
