1. Adipic acid is produced from a mixture of cyclohexanol and cyclohexanone called “KA oil”, i.e. ketone-alcohol oil. The KA oil is oxidized with nitric acid to give adipic acid, via a multistep pathway. Early in the reaction, the cyclohexanol is converted to the ketone, releasing nitrous acid. Among its many reactions, the cyclohex...

~ also known as polyepoxides; EP 828 acrylate; ED 20 acrylate; E 44, acrylate; YD 128 acrylate; Pacrosir VE 196, etc. is a class of reactive prepolymers and polymers which contain epoxide groups.

Epoxy resins may be reacted either with themselves through catalytic homopolymerization, or with a wide range of co-reactants including polyfunctional amines, acids, phenols, alcohols, and thiols. These co-reactants are often called hardeners or curatives, and the cross-linking reaction is referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer. As of 2006, the epoxy industry amounts to more than US$5 billion in North America and about US$15 billion worldwide.

In a controlled environment, the fastest-growing orientation of graphene crystals overwhelms the others and gets “evolutionarily selected” into a single crystal, even on a polycrystalline substrate, without having to match the substrate’s orientation. An Oak Ridge National Laboratory-led team developed the novel method that produces large, monolayer single-crystal-like graphene films more than a foot long.

A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals...
