@Explosions_Fire

I make Youtube videos on chemistry and energetics occasionally. Would do more but it's hard ok. 'Backyard Science' 🇦🇺

Do you think extractions&ire is in Virat Kohli’s top 10 favourite chemistry youtube channels? I like to think it is

A group of Spanish and Mexican researchers loaded 25,000 hexagonal dice, each with a side of about half a centimeter, into a transparent cylinder. They then applied different agitation effects to the cylinder to see which one could cause the most effective compaction. Initially they started shaking the cylinder by rotating it alternately, about once a second, clockwise and then counterclockwise. This alternating rotation method worked best, but only when the rotation was fast enough. The rotation applied a force to the dice facing the walls of the container. At the same time, when reversing the direction of rotation, the periodic shocks caused an oscillation of the stones. By adjusting the speed of rotation, the researchers were able to vary the strength of these shocks. With an acceleration of 0.52 g, the stones end up in a concentric ring pattern in horizontal layers inside the cylinder after 10,000 alternating rotations. However, at lower speeds, it can take years for the rotation to provide the ideal compaction. The researchers hope that their method is a possible new means of compacting materials as part of fabrication processes or even packaging granular materials. In fact, this method turns out to be much more efficient than tapping. In fact, a granule system, when tapped, does not reach a maximum density state of its own, but tends to get stuck in an intermediate density state.

@lukeweston Yeah I guess ‘industry’ I meant hospitals and research. Interestingly though PsiQuantum have committed to building their quantum computer array in Brisbane, and will install a full cryoplant for it! No local helium supply though

@Explosions_Fire Do we actually use helium in industry though? No advanced manufacturing. Aside from MRI, NMR and research? Nobody here is pulling Si boules or running large accelerators, or spacecraft. Apparently it’s quite good for MIG/TIG on high thermal conductivity metals, but rarely used.

Not to rant but the fact that Australia produces no helium is ridiculous. The amount of natural gas we produce is enormous, yet no one refines the helium out so we are 100% reliant on importing it for all the critical industries that require it

at any moment Trump could stop exports of US helium and the price would skyrocket over already historically high levels. In the past month the price of a cylinder here has doubled because…. ? And the local supplier has been on back order for 2 months due to supply issues lol

@David_Fawcett Rare earths are hard, so I kinda get that. But we barely make steel or refine lithium ore

@Explosions_Fire It's also insane we don't refine rare earth's, make quality steel and a dozen other things. Energy prices are too high, and government regulations are too strict.

Every ‘securing sovereign supply chain’ effort is like ‘we made this foreign nation pinky promise to keep selling us this item at whatever price they chose- and no one will break a pinky promise!’ Rather than like, building any refinery

explosions&fire is not science communication. science is a vehicle for the video to make statements that will not resonate and perhaps not even be perceived. i am desperate to not communicate with the viewer.
