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.
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 ...
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.
Materials science in science fiction is the study of how materials science is portrayed in works of science fiction.The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no ...
Spy-fi can be defined as media that centers around the adventures of a protagonist (or protagonists) working as a secret agent or a spy.Usually, these adventures will revolve around defeating a rival superpower or singular enemy from achieving a nefarious aim.
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 ...
Move over, Wordle and Connections—there's a new NYT word game in town! The New York Times' recent game, "Strands," is becoming more and more popular as another daily activity fans can find on ...
Metal rubber is a broad, informal name for several conductive plastic polymers with metal ions produced by NanoSonic Inc. in cooperation with Virginia Tech.This self-assembling nanocomposite is flexible and durable to high and low pressures, temperatures, tensions, and most chemical reactions, and retains all of its physical and chemical properties upon being returned to a ground state.
