Organic Functionalization of Carbon Nanotubes

Journal of the American Chemical Society, 2002
A very general and versatile method for functionalizing different types of carbon nanotubes is described, using the 1,3-dipolar cycloaddition of azomethine ylides. Approximately one organic group per 100 carbon atoms of the nanotube is introduced, to yield remakably soluble bundles of nanotubes, as seen in transmission electron micrographs.

Determination of Organic Carbon and Carbonates in Soils

Soil Science Society of America Journal, 1967
Abstract Procedure and apparatus for determining organic and inorganic carbon in soils are described. The digestion acids used differ from those used in common practice in containing no H 2 SO 4 .

Carbon- and Nitrogen-Based Organic Frameworks

Accounts of Chemical Research, 2015
This Account provides an overview of organic, covalent, porous frameworks and solid-state materials mainly composed of the elements carbon and nitrogen. The structures under consideration are rather diverse and cover a wide spectrum. This Account will summarize current works on the synthetic concepts leading toward those systems and cover the ...

A rapid method for the determination of carbonate carbon and organic carbon

Chemical Geology, 1970
Abstract The reaction of gaseous carbon dioxide with a solution of barium hydroxide is used as a basis of an accurate, rapid and inexpensive volumetric method for the determination of carbonate and organic carbon.

Synthesis of Organic Carbonates

2014
Abstract Nowadays, organic carbonates are becoming widely used as solvents due to their low toxicity, as monomers for the preparation of polymers, and several other uses. The use of carbonates as monomers to form polymers, in particular, may expand in the near future causing a large increase of their demand on the world market.
