Also, "graphene-based chips could deliver speeds more than ten times faster than silicon chips" -- wut? The basic reason (I thought) silicon could be used to make integrated circuits is that it is mostly NON-conductive, but can be made conductive in part, so as to form e.g. capacitances, insulated conductors, diodes, etc. But in my ignorance I thought the one thing that graphene has to be, is conductive, completely conductive in all directions. So how can you make the various parts of a circuit in a material that is one big short circuit?
> At room temperature, graphene is also capable of conducting electricity 250 times better than silicon, a rate faster than any other known substance.
Conducting "better", by which I think they are referring to resistance or conductance, has no relation to "speed" of current flow. So that sentence is noise. And I don't think it's possible for current to move 250 times faster even in a superconductor. Current in silicon is already a good fraction of the speed of light.
Their description of a graphene transistor is not much better,
> They then applied a magnetic field to the graphene ribbon, which made them realize they could control the resistance of the flowing current through the ribbon.
This confusing sentence seems to be trying to describe a magnetically-controlled switch, with an applied field throttling the current flow in a graphene conductor. Hall effect?
OK, now you made me try to find something better. The Wikipedia article on Possible Uses of Graphene does talk about transistors but primarily as FETs and says nothing about magnetic control. A magnetic field does produce a Hall effect but this is not the same as a transistor. As for switching speed,  says "In 2013 researchers created transistors printed on flexible plastic that operate at 25 gigahertz" which is fast but not faster than silicon.
As for the "rate faster" sentence, you are misinterpreting it. It's referring to the amount of charge transferred per time unit, not speed of propagation. See
Reduce R and I goes up.

A *factor of 30 would be unreal. Anything more than 2 in the real world would be amazing.
That's what I think of when I hear "30x improvement", at least.
Hopefully this news triggers a wave of new investment built on hype with a few companies that actually succeed, enabling another platform for even more new innovations.
The capability to control graphene layer properties defines its usefulness for the desired application. Whether this be physical (mechanical strength, porosity, thickness of stacked layers), electrical (conductivity, carrier density, band gap availability) or otherwise (thermal conductivity, transparency, flexibility).
In U.S. English, "spin-out" usually refers to an automobile spinning while out of control, for example when it hits a patch of ice and gets uneven traction.
If they have samples, I'd expect them to want to distribute those (hell, every time I see a graphene related company I look on how I could buy a sample), but I'm not even sure about what I'll get after contacting them. Is the contact there for investors only? For hiring?
If they want people to start using their graphene for something, they may need to add a "get a sample" button somewhere. They may not be vaporware (there are enough labs producing some kind of graphene out there, there are even sites that are more clear on what they produce and yet aren't clear enough on how to get some), but there isn't a line of people wanting to jump over any obstacle to get it either.
