If this is what component formulation is all about I'm done pretending I can figure anything out. What is "high temperature shear stable nanographite dispersant". It's amazing just how much chemistry goes into oil formulation. Looks like this is a patent application for a unique dispersant.


Oil Base Stocks
[0043]
The petroleum liquid medium can be any petroleum distillates or synthetic petroleum oils, greases, gels, or oil-soluble polymer composition. More typically, it is the mineral base stocks or synthetic base stocks used in the lube industry, e.g., Group I (solvent refined mineral oils), Group II (hydrocracked mineral oils), Group III (severely hydrocracked oils, sometimes described as synthetic or semi-synthetic oils), Group IV (polyalphaolefins), and Group VI (esters, naphthenes, and others). One preferred group includes the polyalphaolefins, synthetic esters, and polyalkylglycols.

Indeed. It's equally amazing how some members are firmly convinced they can do a better job by mixing up a "Frankenbrew" in their garages.

Yep, it is persistent the inovation of lubricant enhanced by graphite, but, curious is the fact that you dont see much of it in the consumer products side. Another great property of graphite is the termal conductivity between oil and hot engine parts, because is a high density (2) lubricant, when a small quantity has double mass as compared with (.88) density of average oils.

Although not the same, reminds me of this recent thread about crumpled graphene balls...

Lol, no way. I studied "buckyballs" in the early 90's, they are only 60 atoms in size. So small they exhibit quantum behavior in the aggregate.

Yeah, I read that they've diffracted them through double slits...that's amazing...

Ahhhhh…..material science in the 90's. If you weren't working on buckyballs, then you had to be working on High Temperature SuperConductors (HTSC), otherwise you were so 1970's and uncool.

HTSC in the 90's, we were just ten years away from room temperature superconductors (zero ohmic resistance) and almost free energy. And then we realised that we always would be ten years away…..

LOL 60 atoms is a pretty big (several molecules Polymeric) substance, you get quantum behavior in subatomic microcosmic, fotons and such, never in a division of 60 atoms. You can easily divide H2O! Imagine a buckball... Study again.

Shannow, Yeah, they made graphene sheets, with double tape slits on a flick of nano graphite. Peeling out the tapes they got a sheet of graphene in the face of each tape.

What?
 
I had a one minute read of this patent and thought meh.

This is a patent for a stable nano-graphite dispersion in what looks like a bog standard engine oil. It's not a nano-graphite dispersant per se. The milled graphite is being kept in suspension by conventional PIB-Succinimide ashless dispersant and Dispersant VII. Without wanting to sound like a smartarse, isn't this sort of what you get in used Heavy Duty Diesel Oil except we call the nano-graphite particles, soot?

It I scanned it properly, the big claim for this invention is that it increases the thermal conductivity of the oil. I can readily accept this but I'm struggling to think why this might be a benefit. I can see that this might possibly make for a cooler engine but the engine's water coolant system is the primary regulator of engine temperature. For the majority of engines, the oil temperature sort of 'floats' and follows.

No doubt someone somewhere will have a go at commercialising this stuff but my gut feel is this one is destined to go the same way as the Sinclair C5...

Pontual, you must seriously love the taste of shoe leather, yet again, you've got to take your shoe out of your mouth...

Quote:
The formation of an interference pattern when a beam of particles passes through a double slit is the classic signature of the wave-particle duality of quantum particles. Wave-particle duality has been observed with electrons, atoms and small molecules. Now Markus Arndt, Anton Zeilinger and co-workers at the University of Vienna in Austria have observed wave-like behaviour in a beam of carbon-60 molecules - which are an order of magnitude larger than any other particles for which quantum interference effects have been observed (M Arndt et al. 1999 Nature 401 680).
The Vienna team sent a collimated beam of carbon-60 molecules through a slit made of silicon nitride and detected the interference pattern by ionizing the molecules with a laser and then counting the ions. The slits in the diffraction grating were 50 nanometres wide and the grating had a period of 100 nanometres. The team detected the central maximum and the two first-order diffraction peaks in the interference pattern. The molecules had a most probable velocity of 220 metres per second, which corresponds to a de Broglie wavelength of 2.5 picometres (2.5x10-12 metres) - some 400 times smaller than the diameter of the molecules. They also observed wave-particle duality in carbon-60 molecules that contained one or two atoms of 13C, the heavy isotope of carbon.


It was a huge finding...akin to difracting an elephant.
 
The discussion is about possible division of a buckball. Now if you ionize a particle with laser and get a waveform with some quantum behaviour, you found nothing against it. Stuck it, up yours now?
You cant throw everything you find on the father of the dumps, in here to take heed, just to look fine and contradict.
 
Pontual, quantum effects technically exist at even macroscopic levels. They get much, much harder (i.e. smaller by orders of magnitude than the error bar for the measurements of the object itself) to detect in such cases. I had professors who used to make us calculate Heisenberg uncertainties for macroscopic objects just to demonstrate that.

OK, you're right. I'll tell you what, we can get back to that discussion if you explain this:

So are you saying you can spilt a water molecule by mechanical shearing?
