Carbon pyrolytic, coupled

Perhaps the single most versatile class of material is carbon. Pyrolytic graphite, glassy (vitreous) carbon, various polymers or oil-impregnated or paste electrodes have been used. There is a growing awareness of the complex surface chemistry of carbons, coupled to an appreciation of the great electrochemical differences between apparently similar forms of the material In practice, mechanical chemical and electrochemical pretreatment methods are usually essential if reproducible results are to be achieved. 

C2H6, respectively, using explicitly correlated coupled-cluster theory with singles and doubles combined with standard coupled-cluster theory with up to connected quadruple excitations. Transition-state theory has been used to compute the respective reaction rate constants in the temperature interval 250-1500 K. The computed rates for the reaction to ethane are orders of magnitude slower than those used in the mechanism of Norinaga and Deutschmann (Ind. Eng. Chem. Res. 46 (2007) 3547) for the modeling of the chemical vapor deposition of pyrolytic carbon. 

Isotropic pyrolytic carbon exhibits excellent stability under neutron irradiation. This, coupled with its high strength, dense isotropic structure, and impermeability to gases, makes it the material of choice for the coating of nuclear fission particles to contain the fission products.PIP I The coating is produced in a fluidized bed (see Sec. 2.7 above).
