Piezochemistry

Of especial interest in the context of gemstone metamaterial technology
is highly anisotropic (and highly localized) pressure in piezomechanochemistry which covers both
piezochemical mechanosynthesis and Chemomechanical converters.

By current day (2023 ...) means in most cases what is investigated in the context of piezochemistry
is the effect of extreme isotropic compression in diamond anvil cells].
g. to figue out what is happening in planets interiors.

Thus the for discussion of gem-gum-tec relevant aspects
here in this wiki we'll use the novel term piezomechanochemistry.

The plan is that this page here will rather be used discuss
bulk high pressure piezochemistry eventually. It's usefulness and limitations.
Current day and in future gem-gum-tec.
For now see: high pressure

Bulk pressure piezochemistry future tech

Possibly room temperature superconductors wires where superconductivity is induced by extreme (semi)bulk pressure.
Thick walled tube segment squeezing as a very easy (weirdly satisfying) method to attain nanoscale wires with cores that are under ultra high pressure.

Bulk pressure piezochemistry current tech

Current day autoclaving containers are needed.
All larger scale products (excluding shock impact nano-mineralization experiments) are under
the very hard constraints of thermodynamic equilibrium. Simulated deep Earth hydrothermal processes.
Some amazing gems can be made. But all are bulk crystals in pretty much lowest energy state.
Granted often (very stably) metastable at room-temperature including diamond that wants to be graphite.

• leukosapphire (this is gem quality corundum) – colored variants: sapphire, ruby, padparadscha, ...
• beryll – colored variants: emerald, aquamarine, ...
• quartz – colored variants: amethysts, citrine, smokey, ...
• tourmaline – (quite complex crystal structure and many possible end-members thus many colors)
• topaz – (Mohs 8 defining mineral)
• diamond & moissanite – technical gems
• peridot (this is gem quality olivine - typically yellowish green)
• laser-medium-gems –(often need less extreme growing conditions - to check)
• ...
