Ring-opening polymerization - Wikipedia
The mechanism is affected by the stability of the resulting cationic species. For example, if the atom bearing the positive charge is stabilized by electron-donating groups, polymerization will proceed by the S N 1 mechanism. The cationic species is a heteroatom and the chain grows by the addition of cyclic monomers thereby opening the ring system.

Ring spinning - Wikipedia
Ring spinning is a method of spinning fibres, such as cotton, flax or wool, to make a yarn.The ring frame developed from the throstle frame, which in its turn was a descendant of Arkwright's water frame. Ring spinning is a continuous process, unlike mule spinning which uses an intermittent action. In ring spinning, the roving is first attenuated by using drawing rollers, then spun and wound ...

Anaerobic benzene degradation by bacteria
Oct 14, 2011· Benzene degradation in laboratory microcosms – electron acceptors and 'key players' Benzene‐mineralizing laboratory microcosms have been established under several electron‐acceptor conditions; in most cases, successful enrichments of anaerobic benzene degraders were established by using anoxic sediment or soil taken from petroleum contaminated sites (for an overview see Table 1).

Properties of Graphene – Graphenea
Graphene Structure. Graphene is, basically, a single atomic layer of graphite; an abundant mineral which is an allotrope of carbon that is made up of very tightly bonded carbon atoms organised into a hexagonal lattice. What makes graphene so special is its sp2 hybridisation and very thin atomic thickness (of 0.345 nm). These properties are what enable graphene to break so many records in terms ...
