Oh brilliant.
Now they'll finally be able to justify the ridiculously high price of replacement (graphene) ink cartridges.
Long gone are the days when the inkjet printer was the consumable that people bought for school projects and family photographs: a group of researchers from Cambridge University has added graphene-based transistors to the list of things that you can take from the output tray. The researchers, led by Andrea Ferrari of the …
Nanotechnology is hard.
Pencils are great at smearing down a disorderd streak of graphite particles and binding material; this bears a similar relationship to graphene circuitry as sand does to silicon-based semiconductors.
Graphene seems to have been known about since the 60s. What sort of 'before' were you thinking of?
Yes I wondered that too. But then again, if it's a field effect transistor the gate would be near but isolated from the channel, so perhaps it's been left out for clarity. As it is drawn it would appear to be a diode.
Wouldn't fancy the cost of replacing the gold/chromium cartridge in that thing either.
Used extensively in the fine chemical industry - it's a high-boiling point dipolar aprotic solvent meaning it has a high dipole that helps to solubilize materials but isn't capable of ionizing under 'reasonable' conditions.
Reading the data sheet is a bit like looking up your symptoms in a medical dictionary - scary
With correct handling, ventilation and recycling it's no problem. Doesn't mean that you should be using it in a 'normal' inkjet printer though
