Taking star polymers as an example, RAFT differs from other forms of living radical polymerization techniques in that either the R- or Z-group may form the core of the star (See Figure 10). While utilizing the R-group as the core results in similar structures found using ATRP or NMP, the ability to use the Z-group as the core makes RAFT unique.
4,4′-Azobis(4-cyanopentanoic acid) (ACPA) is a free radical initiator used in polymer synthesis. [1] ACPA is a water-soluble initiator used in both heterogeneous and homogeneous free-radical polymerizations.
A Carley float. The Carley float (sometimes Carley raft) was a form of invertible liferaft designed by American inventor Horace Carley (1838–1918). [1] Supplied mainly to warships, it saw widespread use in a number of navies during peacetime and both World Wars until superseded by more modern rigid or inflatable designs.
Raft is a consensus algorithm designed as an alternative to the Paxos family of algorithms. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features. [ 1 ]
A raft is any flat structure for support or transportation over water. [1] It is usually of basic design, characterized by the absence of a hull . Rafts are usually kept afloat by using any combination of buoyant materials such as wood , sealed barrels , or inflated air chambers (such as pontoons ), and are typically not propelled by an engine.

The JUNK Raft Project was organized by Dr. Marcus Eriksen, Joel Paschal and Anna Cummins in Long Beach, California in 2008, to bring attention to the issue of plastic pollution in the Great Pacific Garbage Patch. The project was launched with the Algalita Marine Research Foundation, after founder Charles J. Moore encountered the patch in 1997. [9]
