supercooled rubberband airplane twist; catalyst carrier polymer
Just like putting 300 turns of a rubberband airplane rubber band, supercooling it, and then watching the polymer counter rotate 300 times when supercooled; use this to make always fresh surface polymer blobs full of catalysts so the catalysts always rotate to freshness
If you've ever watched a cookie shake in a blender you
see visually how the particles stick up in the rotating
of semisolid ice cream for awhile then get
into the bulk. If there are sprinkles the sprinkles rotate
which are on top and most sticky-outy.
be possible with polymers, that is the
would have a memory-material urge to internally rotate
and push out, so if it were a rubber with catalyst
acting as cooled rubber at room temperature the surface
would change which sprinkles were on top and outside.
Twisted rubber as a kind of metaphor and very near the
actual technology: if you take a condom, twist the
say 100 times it will rotate 100 times to reach
again, so again it may be possible to put a twist in a blob
of polymer, or 100+ circular twists that then resolves
(unwinds) itself if cooled down to super slowness by
rotating (and again, bringing new and different sprinkles
So, you've got a plastic blob that spends 100 days, or
days gradually untwisting from memory plastic rotaion
effects, one full time-delay rotation every 24 hours.
do you do with it? Change chemistry! Load it up with
catalysts and reactive chemical reagents of course as
Due to the autorefreshing of the surface the polymer
always presents fresh surface to the reaction liquid or
so fresh reagent or catalyst always faces the other
reactants in solution or at gases. This has notable
at catalysts (and enzymes), this could make it so a
catalytic converter always has a fresh surface to remove
pollution. It could be used to make always-fresh surface
catalysts for the oil and gas refining industry or the
chemical process industries to make other chemicals in
bulk even more cheaply than they are made now.
The long lasting duration of auto-refresh self-stir
in-polymers could make it so the chemical process
had to reload catalysts into continuous process reactors
much less often, maintaining and extending their
continuous, highly value effective non-batch continuous
It is even possible that this "always fresh sprinkles
on top" effect makes it so already studied catalytic
chemicals that previously did not function long enough or
that "fouled" easily could be back in the running as
chemical catalysts. One advantage is that these other
catalysts may have preferred yield profiles, that is they
make 98% something instead of 80% something. Self-stir
polymer matrix for catalysts increases the number of
actual chemical catalyst unique chemicals available for
reactions. This also makes new cheaper catalytic
(antipollution) materials possible, because the chemists
can design new catalysts around short-lifetime catalyst
chemistry which might use cheaper metals.
If you do not like supercooled twisty condom rubber as a
metaphor for the technology, there is a completely
different way to do it: abradable laser scored mica
sandwiche. Basically you coat mica with a catalyst, hold
the thousands or tens of thousands or hundreds of
thousands of layers together with a central bolt, then
tumbling around the reaction vessel the mica abrades
disintegrates predictably, always exposing fresh catalyst
surface on the laminate shape. A laser scores the mica
sandwiches as the mica is produced (and of course pre-
so it extra-predictably breaks down, also you don't have
use mica you can just use any predictable disintegration
from abrasion polymer as a sandwich layer.

youre reading my mind
||Aren't most catalytic converters made of things that don't like
to twist and untwist? Like platinum and metal?
||I like the whole concept of adding little twisty stresses to
chemistry to see what happens. I say, add some convincing-
looking graphs and charts, and submit it to the Nobel
committee or somewhere where people with degrees, lab
coats, and test tubes hang out.
||At the very least, make a nanoscopic rubber band airplane.
||Is it possible to write this in plainer language?
||"Extend availability/lifetime of chemically reactive
by incorporating them into stressed, folded or twisted inert
substrates. As the substrate rebounds, clean/unused
material exposed for reactions."
||Is that about it? The bit about supercooling or laser etching
to make the substrate rebound take longer? And the bit
condoms is because, well, it's a beanangel posting?
||Oh, the quoted part is for making it better, you may have
read an earlier version with that in it.
||Basically, if you imagine the little sprinkles in the polymer
that contain the catalyst or reagent to be coated, like
vitamin E gelcaps then: Extend availability/lifetime of
chemically reactive compounds by [putting them in little
vitamin e capsules] or incorporating them into stressed,
folded or twisted inert gradual remotioning substrates.
[you can use millifiore technique to put stripes of catalyst
or reagent with a coating layer at a polymer blob] As the
substrate motionizes/untwists/rebounds, clean and
unused catalyst material or reagents are exposed for
||When I run the thought experiment with the twisted condom, the
inside and outside of the condom do not change places. But
the application proposed for this idea seems to require that
inside and outside should change places.
||So we put down the condom and switch on the blender. Then
inside and outside do change places, but then the movement is
not driven by the unwinding elasticity of the substance being
||Myosin and Actin are the muscles molecular motor. Maybe twisting long fibres interlocks these molecules and when supplied with ATP they slowly walk out the twist. A lot of accurate molecular geometry to work out though.
||This idea does sound like a material with a whole lot of those suction cup pop-up toys as molecules or a slowly unbinding velcro.
||//slowly unbinding velcro// That's new to me and very
intriguing; the memory polymer velcro layer-sphere could
just detach at a predictable rate to release fresh
catalyst/fresh catalyst surface. Gradual-reveal velcro is a
little like the stack of mica coasted with catalyst though.
