Freeze Ray improves cryogenics
hypermicrocrystals are good Thus alter the thermodynamics of crystallization to favor minute over large Technologically this goes with variable IR or acoustic absorption at different crystal sizes as well as creating hyperdiamagnetic IBP proteins that modify ice shape as it forms | |
When freezing tissue to maintain characteristics or maintain revivability hypermicrocrystals or glassification are good Bigger ice crystals are known to cause membrane disruption as well as fracture
Everything from TV dinners to cryopreserved eggs n sperm as well as cryogenically preserved human
lives benefit from better cryopreservation techniques
Thus alter the thermodynamics of crystallization to favor minute over large at the phase change point; even if large crystals would ordinarily form thermodynamics can be nudged to favor microcrystals or glassification
Thus to make tiniest size ice grains make small grains more thermodynamically stable Three ways to do this are reradiance radii that cause ice crystal radius change as a result of larger crystals warming as they grow
what if you could add IR absorptive material to IR illuminated ice matrix while it was crystallizing The effect would be that the larger crystals would be warmer that is less stable than the the slush that has less IR absorption very gradual freezing under the right amount of IR creates the tinyest crystals
You may well object that crystals form their lattices as an exclusionary purifying process Yet viewing nature the color differences between gemstones is caused from the slightest chemical variation at their lattices Aiming an IR laser at a white diamond gets a different warmth result than from a colored diamond Thus I think water ice crystals could be IR absorption shifted with a physiologically benign chemical
Another way to impart meltation energy to larger crystals thus thermodynamically favoring tiny crystals is acoustics A crystal grain has a resonant size as well as a sound absorption frequency range Thus ice crystallization amongst a variety of crystals of different sizes will favor those not absorbing sound energy With an audio beam you could always keep the larger crystals from forming as either their internal or edge surface energies would tend to be higher than the slush
Diamagnetism is illustrated with the way at high magnetic fields water can be levitated with a magnet Thus a hyperdiamagnetic version of a natural Ice blocking protein that accumulates around the surface of forming ice crystals could be energized with a big magnetic field
put another way the antifreeze proteins of fish n plants could have a highly diamagnetic bismuth atom on them Placing a slush of this material at a magnetic field you could vibrate the bismuthized protein to keep large crystals from forming
Thats three kinds of cryopreservation Freeze Rays Optical with uptake of IR absorbing chemical to ice Acoustic based on sound antenna size Diamagnetic based on being able to electroadjust or stir a crystallizing fluid where proteins meet fluid
It might even be possible to favor microcrystallization along a particular direction I read about a researcher creating 3d patterns of music possibly as a side project to building ion moters (SciAm) a 3D acoustiscape could be used to cryopreserve neurons over capillaries or the cleverest regions of an oocyte

By using semiconduc...by natural stimuli.
tissues can be monitored as to optimal function right to the freezing point By using semiconductor nanoparticles as tiny solar cells, the scientists can excite neurons in single cells or groups of cells with infrared light. This eliminates the need for the complex wiring by embedding the light-activated nanoparticles directly into the tissue. This method allows for a more controlled reaction and closely replicates the sophisticated focal patterns created by natural stimuli. [beanangel, Feb 24 2009]

Explain how a "Freeze Ray" works, please. |
|
| |
Actually, this is not such a stoopid idea. |
|
| |
What he's saying is this:
(a) Cryopreservation of large things is difficult because the
gradual cooling encourages the formation of large,
damaging ice crystals. |
|
| |
(b) You could disfavour large ice crystals if you can find a
way to selectively impart energy to them, as opposed to
smaller (better) crystals. |
|
| |
(c) You might be able to do this by finding an IR absorber
which is incorporated in growing ice crystals; hence, larger
crystals absorb more IR (energy) in proportion to their
surface area, and hence will tend to melt (or not grow),
whereas smaller crystals will be favoured |
|
| |
(d) Another option might be to use some kind of
resonance process (eg acoustic) tuned so that larger
crystals absorb more energy and are hence disfavoured. |
|
| |
It actually makes sense, more or less, and is interesting, so
I will grit my teeth and bun it. |
|
| |
... so the goal is ice crystals that are so small there's only a mono-molecular layer of whatever else is in the solution between them (?) |
|
| |
I think the goal is to make the ice crystals as small as
possible, approaching a glass (a non- or micro-crystalline ice).
You can do this for cells, small tissue samples etc and retain
viability because you can freeze almost instantaneously.
For bigger pieces of meat, like grandparents for example, it's
more difficult. |
|
| |
I thought to avoid the large crystals you were supposed to refrigerate anything you intended to freeze until it was about 40 degrees prior to freezing. |
|
| |
Do apostrophes not count as punctuation then? |
|
| |
//you were supposed to refrigerate anything you intended
to freeze until it was about 40 degrees prior to freezing.//
Yes, that helps, but not much. The idea behind that is
that you bring everything close to freezing, so that the
final freezing step can be quicker. |
|
| |
However, it doesn't help very much. Very little energy has
to be removed to go from ambient to just-above-freezing.
Almost all the energy removal happens when you go from
just above freezing to frozen - latent heat of fusion of
water. |
|
| |
I actually think (and believe me, I am the last person to
say this rashly) that Beanybaby's idea of using resonance or
energy absorbtion to disfavour large ice crystals is
potentially a good one. And my fee for translating is quite
modest. |
|
| |
//And my fee for translating is quite modest.//
That sounds like a halfbakery idea right there. |
|
| |
You give this idea way to much credit. I employed my delete key and extracted the idea. It's not much. |
|
| |
When freezing tissue ice crystals are known to cause membrane disruption. |
|

Cryogen(ics) would benefit from better cryopreservation techniques (that) favor minute crystals over large . |
|
| |
1) To make ice grains small you could add IR absorptive material to IR illuminated ice matrix while it was crystallizing (??) The effect would be that larger crystals would be warmer than the tinyest crystals |
|
| |
You may object that crystals form their lattices as an exclusionary purifying process Yet viewing nature the color differences between gemstones is caused by chemical variation at their lattices. ice crystals could be IR absorption shifted with a physiologically benign chemical (???) |
|
| |
2) Another way to impart energy to larger crystals is acoustics A crystal grain has a resonant size as well as a sound absorption frequency range favor(ing) those not absorbing sound energy(,) an audio beam could keep the larger crystals from forming. |
|
| |
3) Diamagnetism of a natural Ice blocking protein could be energized with a big magnetic field to keep large crystals from forming |

Better put those in a zip-loc bag, [nineteenthly], or they'll roll away. |

Well that's a reason for a fixed-width font if ever there was one. |

It's a really bad sign if you can remove 90% of the words without loosing any of the content. Not sure if it's a snow job or if the intention is to bore the reader into an uncritical fung. |

[bigsleep]: // microwaves tend to cook from the inside out. //
Yes, but only to a depth of an inch or less under the surface. I suspect IR would penetrate even less. |

[beanangel]: let [MaxwellBuchanan] and [WcW] show you the way to bun-related profit |

MaxB, thanks for summarizing the idea. You were mighty brave to read it. |
