Quoting: "[S]cientists are still trying to devise a cost-effective way to produce graphene at scale. Companies like Samsung use a method pioneered at the University of Texas, in which they heat copper foil to eighteen hundred degrees Fahrenheit in a low vacuum, and introduce methane gas, which causes graphene to "grow" as an atom-thick sheet on both sides of the copper—much as frost crystals "grow" on a windowpane. They then use acids to etch away the copper. The resulting graphene is invisible to the naked eye and too fragile to touch with anything but instruments designed for microelectronics. The process is slow, exacting, and too expensive for all but the largest companies to afford. ... Nearly every scientist I spoke with suggested that graphene lends itself especially well to hype."
I became a regular employee of the company I work for just this week, making me the newest in one sense.
I've been contracting for them since 2009, which would put me in the middle of the pack.
I started working for the company that merged into this one way back in 2003, and I'm the only one who used to work for that company still left, as well as having been at one or the other longer than most employees of the current company.
