This is a scam. On the Telegram group, in which you cannot chat btw, they have a post that says they have participated in the 14th International Conference on Functional Energy Materials and there is a plaque/diploma the two supposed founders are holding. The picture is actualy a photoshoped picture from this website in which they mirrored the photo and put the graphene logo on the diploma.
There is absolutely no trace of any of the team member on the internet, im not talking about LinkedIn profiles, Im saying ANY trace whatsoever.
