✦ Synopsis

By-products related to fuels NMR spectroscopy.

Structural characterization by elemental analysis, FTIR, and NMR spectroscopy on both vacuum-distilled and air-blown pitches showed that distillation of lighter fractions, reduction of atomic H/C ratio, and dehydrogenation raised their softening points. Structural analysis by NMR showed that asphaltite pitches consist of condensed aromatic rings combined with methylene bridges and heterocyclic groups and substituted with alkyl and naphthenic groups. Aspbaltite pitches, which were prepared by solvent extraction (HI-BS) and vacuum distillation (AVD3), resulted in very good and medium spinnable green fibres, respectively. Scanning electron microscope analysis was used to study the morphology of the stabilized fibres. 00100236

The microporous phase of carbonaceous materials is characterized by means of fractal dimension D, determined on the principle of the coverage of microporous body of ideal shape with a monolayer of molecules of various sizes. A part of molecules remains lying on the external surface of the solid phas

## Intercalation of Ni atoms under a two-dimensional graphene film (ZDGF) on ( 111) Ir was studied in ultra high vacuum using high-resolution Auger spectroscopy. Ni atoms were shown to be intercalated effectively at 900 to 1500 K, and a polylayer nickel film was shown to grow under the 2DGF. A rel
