Carbon Nanotubes

The structure of a carbon nanotube is formed by a layer of carbon atoms that are bonded together in a hexagonal (honeycomb) mesh. This one-atom thick layer of carbon is called graphene, and it is wrapped in the shape of a cylinder and bonded together to form a carbon nanotube. Nanotubes can have a single

Acetylene

Acetylene alkylates the cytochrome P450 prothestic heme. This alkylation is coupled with catalytic turnover by the target enzyme and results in suicide inactivation of the enzymes. The oxidation of acetylene appears to result in the highly instable epoxide that rearranges to the keten. The structure of the prosthetic heme adduct is -CH2CHO.

FRUIT RIPENING

FRUIT RIPENING Ripening is the process by which fruits attain their desirable flavour, quality, colour, palatable nature and other textural properties. Ripening is associated with change in composition i.e. conversion of starch to sugar. On the basis of ripening behavior, fruits are classified as climacteric and non-climacteric fruits.

One such structure is carbon nanotube; Carbon nanotubes (CNTs) are hollow cylinders of carbon atoms. Their appearance is that of rolled tubes of graphite, such that their walls are hexagonal carbon rings, and they are often formed in large bundles. The ends of CNTs are domed structures of six-membered rings, capped by a five-membered ring.
