Intrigued by Graphene

[82lsju]

Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit—meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. The demonstration, which used a new kind of graphene-based qubit, represents a critical step forward for practical quantum computing, the researchers say.

Encouraged by an early link to video of a tiny live frog apparently being tumbled weightless in some sort of levitation field, have followed this thread for four years plus, waiting for graphene research to prove conclusively that USC sucks.  So far we only have tradition and the evidence of our own eyes to validate the proposition, which should be OK because graphene is just one atom thick and transparent so everyone could see that USC sucks.  But time passes and the lack of research progress into this pressing matter is...concerning.

He had a brain the size of a qubit and skin as thin as a sheet of graphene.

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.

A new study shows that graphene sheets can block the signals mosquitos use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention.

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?"

This pioneering work demonstrates that the integration of GRMs inks with on-demand morphology and tuneable optoelectronic properties in a tandem structure, can lead to high-throughput industrial manufacturing,” he said. “Graphene and related materials improve the performance, stability and scalability of these devices.

Well duh, that's obvious.  ;>)

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

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.

You beat me to it; I heard about this in the Economist's weekly podcast, and was going to post.

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.
