beammeup, thanks for posting this article.
I am interested in the line regarding liquid super crystalline structure with regards to vibration and electrical charge.
thanks again

am reading the entire glossary plastics A large group of polymers that has properties between elastomers and fibers. As such, plastics have a wide range of properties such as flexibility and hardness and can be synthesized to have almost any combination of desired properties self-assembly The aggregation of molecular moieties into more ordered structures that are thermodynamically stable and involve noncovalent bonds. Crystallization is an example of such self-assembly. Self-assembly is used to build nanostrucures such as inorganic clusters and lattices, nanotubes and channels, host-guest complexes, monolayers, hydrogen-bonded networks and systems of intertwined molecules super critical fluids A substance above its critical point on the temperature/pressure phase diagram. Above the critical point, the fluid is neither a gas nor a liquid but possesses properties of both. The viscosity of a supercritical fluid is at least one order of magnitude higher than the viscosity in the gaseous state, but is one or two orders of magnitude less than in the liquid state thermosets A type of plastic that must be cured, forming network-like structures that do not soften at high temperatures. -------------------------------------------------------------------------------- thermotropic Liquid crystal molecules which exhibit temperature dependent liquid crystalline behavior. See also: lyotropic -------------------------------------------------------------------------------- threading When a nemaparallelepipedtic liquid crystalline material shows a tangled, thread-like appearance when observed between crossed polaroids in the optical microscope. plc.cwru.edu/tutorial/enhanced/files/GLOSSARY/Glossary.htm
