I'm intrigued by the ability to wear a graphene patch as a fitness tracker:

Might condensed matter physicists finally build a graphene-based topological insulator?

Physicists were stunned when two twisted sheets of graphene showed signs of superconductivity. Now Stanford scientists have shown that the wonder material also generates a type of magnetism once only dreamed of theoretically.

Graphene goes commericial - triangle2 - 09-25-2019

I am one of the many people on the board who has truly enjoyed the multiyear thread about Graphene. I never really thought that following the thread was preparing me to feign scientific coolness when a friend shoved her laptop in front of me and said "what the hell is Graphene?"

Well duh, that's obvious.  ;>)

not exactly graphene but "white graphene" may extend Moore's law

Quote:In the current state of the art, the smallest components (transistors and diodes) made on a silicon chip are about seven nanometres (billionths of a metre) across. That is a thousandth of the diameter of a red blood cell. But problems are mounting. As components shrink, electrons start to leak from the connections between them, causing interference and unreliability. The prophets of doom have therefore returned. Once again, however, they look like being wrong. The answer to the electron-leakage problem is better insulation between chip components. And a group of researchers in South Korea and Britain think they have the insulator required. It is called thin-film amorphous boron nitride (a-BN).
The wonder that waits

The backstory of this material is intriguing. Boron and nitrogen lie on either side of carbon in the periodic table, one consequence of which is that materials composed of equal numbers of boron and nitrogen atoms crystallise in the same ways that carbon does. There are, in other words, boron nitride equivalents of diamonds and graphite. There are also boron nitride versions of the tiny arrangements of carbon atoms known as fullerenes and nanotubes. So it was no surprise, after the creation in 2004 of yet another allotrope of carbon, graphene, which consists of single layers of atoms arranged in a hexagonal grid like a honeycomb, that it had a boron-nitride analogue. This has come to be known colloquially as white graphene.

Quote:A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current.

"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery.

That's probably what powered the probe droids used by the Empire.  Very intriguing.

Quote:Graphene microbubbles make perfect lenses

...
"For applications requiring precise bubble position and size, as well as high stability—for example, in photonic applications like imaging and trapping—creation of bubbles at accurate positions with controllable volume, curvature, and stability is essential." Jia explains that, for integration into biological or photonic platforms, it is highly desirable to have well controlled and stable microbubbles fabricated using a technique compatible with current processing technologies.

[b]Balloons in graphene[/b]
Jia and fellow researchers from Swinburne University of Technology recently teamed up with researchers from National University of Singapore, Rutgers University, University of Melbourne, and Monash University, to develop a method to generate precisely controlled graphene microbubbles on a glass surface using laser pulses. Their report is published in the peer-reviewed, open-access journal, Advanced Photonics.

Good find, have you ever heard of C60? I continue to be intrigued by Graphene. :-)
