Elastomers are usually thermosets (requiring vulcanization) but may also be thermoplastic (see thermoplastic elastomer). The long polymer chains cross-link during curing (i.e., vulcanizing). The molecular structure of elastomers can be imagined as a 'spaghetti and meatball' structure, with the meatballs signifying cross-links.
Rubber science is a science fiction term describing a quasi-scientific explanation for an aspect of a science fiction setting. Rubber science explanations are fictional but convincing enough to avoid upsetting the suspension of disbelief. Rubber science is a feature of most genres of science fiction, with the exception of hard science fiction.
The phase transition temperature of an azo-liquid crystalline elastomer can be reduced due to the trans-cis isomerization of the azobenzenes during UV-irradiation and thus the liquid crystalline phase can be destroyed isothermally. For liquid crystalline elastomers with a high azo-concentration, a light-responsive change of the sample's length ...
The Universal Being appears again and gives them a clue on how to wake Ms. Bookhart, who will teach them about the books and how to use the library. Figuring out one part of the clue, Abakas starts to read a section of The Story of the Amulet , which wakes up Ms. Bookhart.
One of three stable transuranic elements predicted by the new science of nucleonics in James P. Hogan's Giants series. Not naturally occurring outside of neutron stars, but trace amounts are created at the detonation of nucleonic weapons. Bureaucratium Scientific in-joke: Similar to Administratium and variation of the joke.
Technology in science fiction is a crucial aspect of the genre. [ 1 ] [ 2 ] As science fiction emerged during the era of Industrial Revolution , the increased presence of machines in everyday life and their role in shaping of the society was a major influence on the genre.
Allie Pribula, a 25-year-old TikToker who used to be an elementary school teacher in the Philadelphia suburbs, says she started making GRWM videos as a way to process her feelings about her old job.
The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. [1] The principal difference between thermoset elastomers and thermoplastic elastomers is the type of cross-linking bond in their structures ...
