Secondary microplastics are small pieces of plastic derived from the physical breakdown and mechanical degradation of larger plastic debris, both at sea and on land. Over time, a culmination of physical, biological, and photochemical degradation, including photo-oxidation caused by sunlight exposure, can reduce the structural integrity of ...
Kaynemaile was created as a chainmail fabric that looked and moved like real chainmail, but without the weight, made of polycarbonate resin rings with no joints or seams in the links. [ 5 ] [ 6 ] The material was created by a team of New Zealand based chainmail technicians manually interconnect millions of polypropylene (PP) rings [ 7 ] and ...
In chemistry and biology, a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins ).
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
A master link or quick-release link is a roller chain accessory that allows convenient connection and disconnection of a chain without the need for a chain tool. [1] It acts as a set of the chain's outer plates, so joining two sets of the chain's inner plate ends. Such master links may or may not be re-usable. [2]
The weathering of plastic debris causes its fragmentation into particles that even small marine invertebrates may ingest hence contaminating the food chain. Their small size renders them untraceable to their source and extremely difficult to remove from open ocean environments. [79]
