cheers mate :')
One example was a floor material for care homes that could detect pressure in a 2D sense, so the floor itself could detect "fall events" and track movement + gait etc.
And I think they had a prototype of a similar thing in Australia that weighed all trucks coming and going from a mine just under the road they drove, no need to stop on weighing stations.
No idea where that went.
Nowadays we'd do the fall detection with either a wrist device (any Apple Watch can do this) or cameras + "AI" detection. The floor is a lot more privacy preserving though, it only detected shapes and pressure.
Try not to breathe any, studies are still pending but that stuff gets everywhere.
Literally just, take a process that used to use sand or horsehair or whatever filler, and add a significant portion by mass of asbestos powder instead.
Answering my own question: the WHO estimates it costs 200K lives per year. No estimates on the other side, but that's a big number to overcome...
I'm not sure how to square that with claims like:
> With phenolic resins, asbestos products are produced which will provide insulation and retain strength when subjected to 5,000°F for periods of minutes (1 to 30 minutes) . See Figure 2.1 in which a rocket motor part is subjected to a temperature of 5,000°F. Figure 2.1. Rocket motor aft (asbestos-phenolic insulator) before and after firing at 5,000°F.
> The temperature approximately 1/8 in. from the surface exposed to 5,000°F will be approximately 200°F after 1/2 to 1 min. of exposure.
> When combined with magnesium carbonate and other similar products, heat insulators can be produced which will be useful for many years in such applications as boilers operating at temperatures from 500° to 1,200°F or 1,800°F.
We seem to use a matted "Ceramic Fiber" roll for its high-heat insulation capabilities these days, up to about 2300F-2600F depending on type. Asbestos fiber insulation seems to be good to somewhere between 1500F to 2700F depending on how you use it. Ceramic fiber is carcinogenic in a similar way to asbestos, but apparently considerably safer due to the fiber length/alignment.
I would understand such comment in the context of carbon nanotubes or fullerenes, but graphene? Have you forgot that graphite is literally a bunch of stacked graphene?
Considering how much graphite pencils are used across the world, we would've seen hypothetical negative effects already with a high degree of confidence.
Yes, graphene production aims to produce larger sheets, but it only makes graphene less biologically active, not more.
Graphitosis is the graphite equivalent of silicosis and asbestosis so yes we’ve got plenty of evidence it’s harmful, but it’s mostly a problem with occupational exposure where large amounts of graphite dust are produced.
That might change if there’s tiny sheets of graphene flaking off everywhere from nanocoatings and it turns out to be carcinogenic for the same reason asbestos is (which isn’t out of the question given the studies on CNTs and nanotoxicity in general).
Musou black is what I tried.
Wait what? If this is actually true this Jensen is going to be the richest/most important. If $500B is being invested in Datacenters and this company is raising a few ten million, something isn't adding up here.
It looks like they're using "graphene" as a pigment in the plastic, and I'd wager this probably means "99% conventional black dye and 1% graphene", because why would that matter either way...
