Degree of carbon ordering

The degree of molecular order obtained by NMR as a function of bilayer depth is relatively constant between carbons 1 and 9 and then falls significantly for positions deeper... [Pg.811]

Carbonaceous materials with varying degree of graphitic order are the most common commercial anodes in secondary lithium-ion batteries. Among carbon-based materials, natural graphite is the most promising anode... [Pg.330]

Isotropic carbon fibers, whose degree of crystalline order is exceptionally low and whose structure is similar to glassy carbon, have the poorest mechanical properties. Their strength is, however, sufficient for their utilization as insulting fibers, filter media and for catalyst support. [Pg.378]

Figure 2.8 Raman spectra of various carbon materials vith an approximately decreasing degree of structural order in the following sequence natural graphite (GC2), high surface area graphite (GA2), calcined needle coke (QCA), green needle coke (QVA), isotropic carbon fiber (FCl), and subbituminous coal (CM3). (Reprinted from Ref. [48] with pemussion firom Elsevier.)...

In order to assess the accuracy of the dynamic SDMRG technique, we have performed a series of model calculations we computed the dynamic linear polarizabilities (0(0 )) and third-order polarizabilities (7(0 , 01,0 )) corresponding to the third harmonic generation (THG), for the Hubbard and J7—V polyene-like chains of up to 20 sites with and without dimerizations (note that the dimerization parameter S reflects the degree of carbon-carbon bond-length alternation along the polyene chain nonzero S leads to alternating t and V values while zero 5 means uniform t and V). [Pg.163]
