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.

Hi,
I’m Ben. I work for Black Swan Graphene.
I noticed some of our Black Swan press releases on here, so I thought I’d share our latest announcements that you might not have seen:
Black Swan Graphene and Hubron International enter commercial agreement
Black Swan Graphene announces range of graphene-enhanced masterbatch products
Black Swan Graphene announces distribution and sales agreement with Thomas Swan
Let me know if you have any questions and I will try to get a response from the team!
hi - a computational lithographer here; I wonder how graphene electronics are plan to be scale up in VLSI scheme of things ? Is there a SPICE models for graphene ? Is there some kind photonics / electronics design tool that accepts Graphene ?
Thanks
is there any software available that could print graphene as a tetrahedral polytope on different logarithmic scales?
Hey folks, I just joined this sub and I hope I can find some answers about electrical conductivity. Like using graphene (by itself or mixed with other materials) as interconnection for microelectronic applications, just like the conductive tracks in a PCB for example.
Appreciate the help!
Hello, I am interested in going back to school to learn the production of Graphene. I am seeking advice on which Graphene conference to attend should I go to Graphene Flagship Week in Prague or the Graphene Conference in Madrid?
Is it possible to layup CFRP on Pyrolytic Graphite sheets? The idea is to stack up layers of pyrolytic graphite sheets on an Invar tool and on top of these graphite sheets, CFRP layup to be done. Pyrolytic graphite sheet is chosen for it’s low CTE. Need your feedback, thank you!
Hey are there any good ideas out their for a high school science fair project that involves graphene?
So I've been trying to replicate the method on this paper https://pubs.acs.org/doi/10.1021/acsnano.5b04258 for my work, but I can't seem to make the flakes larger than around 10um in size. Has anyone had any luck with this? Do you have some suggestions? Thanks!

This store is good for Graphene cloth. Use my link for discount 😊
I am looking for partners to research and produce products related to Graphene. We have produced graphene conductive ink and graphene powder with high porosity. However, it is very difficult to find. Can you help me?
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?
Hello,
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.
Hello
TL/DR : Does anyone have a good demo code or blog post showing gathering metrics from Django Graphene GQL queries to Prometheus?
Longer:
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?
