...in simple terms what they mean when they refer to 'half-spin'. They are really talking about minute energy differences in the energy responses of atoms, but they have wrapped up the theory with relativistic notions of four-dimensional space which no one can really understand.
Researchers led by Paul McEuen, professor of physics at Cornell, began by putting a single nanotube in a circuit and giving it three electrical contacts called gates, one at each end and one underneath. They used the gates to apply a voltage across the nanotube, then illuminated it with light. When a photon hits the nanotube, it transfers some of its energy to an electron, which can then flow through the circuit off the nanotube. This one-photon, one-electron process is what normally happens in a solar cell. What's unusual about the nanotube cell, says McEuen, is what happens when you put in what he calls "a big photon" -- a photon whose energy is twice as big as the energy normally required to get an electron off the cell. In conventional cells, this is the energy that's lost as heat. In the nanotube device, it kicks a second electron into the circuit.
Hexagonal relationships [based on the more fundamental attributes of equilateral triangles] can be used to quantify the potential field in any system, according to Bob Smith.
At normal atmospheric pressure, the material's molecules stay relatively far apart from each other. But as researchers increased the pressure inside the chamber, the material became a two-dimensional graphite-like semiconductor.
Source: Washington State UniversityThe researchers eventually increased the pressure to more than a million atmospheres, comparable to what would be found halfway to the center of the earth. All this "squeezing," as Yoo calls it, forced the molecules to make tightly bound three-dimensional metallic "network structures."

The ability to make electrons behave as if they were in magnetic fields of 300 tesla or more - just by stretching graphene
seasmith wrote:Precursor magnetic flux
"We have shown experimentally that when graphene is stretched to form nanobubbles on a platinum substrate, electrons behave as if they were subject to magnetic fields in excess of 300 tesla, even though no magnetic field has actually been applied. This is a completely new physical effect that has no counterpart in any other condensed matter system," said Crommie.
Crommie notes that "for over 100 years people have been sticking materials into magnetic fields to see how the electrons behave, but it's impossible to sustain tremendously strong magnetic fields in a laboratory setting."
The current record is 85 tesla for a field that lasts only thousandths of a second. When stronger fields are created, the magnets blow themselves apart.
The ability to make electrons behave as if they were in magnetic fields of 300 tesla or more - just by stretching graphene - offers a new window on a source of important applications and fundamental scientific discoveries going back over a century. This is made possible by graphene's electronic behaviour, which is unlike any other material's.
Have been toying with idea that graphene's form and structure tend to favor longitudinal trans~missions, over transverse.
And leading magno-signals: waves or domain pattern interface planes.

“ “ Is there really some fundamental discovery here made in terms of electrical dynamics, or is it more akin to a fundamental misunderstanding of already well established EM principles? Guess I'm not getting what the "electron behavior" is that they're describing, and what that behavior is in terms of "real" magnetic influence (real vs "pseudo" as in, I guess, a supposed mechanical action [stress] only), or what the perceived difference is.”

I can't help but notice the similarities between graphene's crystalline and amorphous states when compared to "Liquid Crystals". I'm wondering if the nano-sizing is of such extent that graphene reveals the two states as being fundamental to the nature of propagation of "charge".
Such that the crystalline state is optimal for the 'transference' of "charge" via a material adopting an crystalline phase for the duration of "charge" 'transference', which occurs as a temporary resonant "imbalance" to the material's amorphous and overall "neutral" phase. These are very intriguing qualities:”
Using the technique, the researchers revealed new details about how water coats surfaces. They found that the first layer of water on mica is actually two water molecules thick, and has the structure of ice. Once that layer is fully formed, a second, two-molecule-thick layer of ice forms. On top of that, "you get droplets," Heath says. "It's truly amazing that the first two adsorbed layers of water form ice-like microscopic islands at room temperature," says Xu. "These fascinating structures are likely important in determining the surface properties of solids, including, for example, lubrication, adhesion, and corrosion."
