educational work of group.

• Within the framework of laboratory courses "the
  physical practical work " and " physical bases of
  the information reception" for 3 years students
  of physical and engineering specialities were
  carried out laboratory works by a technique of
  x-ray researches of fullerites and carbon black
  containing fullerenes. Opportunities of
  information reception on crystal structure of
  fullerites of various structure were analyzed.
• Within the framework of a laboratory practical
  work for 4 years students for courses " Methods
  of diffraction researches of materials " and "
  Computer processing of results of diffraction
  experiment " were carried out laboratory works
  "Rietveld analysis of the x-ray pattern of
  fullerite ?60 " and " X-ray pattern indexing of
  fullerites of various structure ".

• On the one hand, this analysis is necessary to
  make search of optimum conditions of
  plasmachemical influences more realized and
  purposeful, on the other hand, it is extremely
  interesting to find out behaviour of the
  materials structure, exposed to so strong
  influences as a result of which occurrence of new
  compounds and substances is possible.
• Structural identification of substance, in
  itself, represents the complex(difficult),
  labour-consuming research problem demanding
  special preparation of samples, the techniques of
  experiment based on diffraction of x-ray
  radiation, and application of a complex of
  mathematical methods for decoding an observable
  of scattering pattern.
• The analysis of products of plasmachemical
  influences on materials is complicated also that,
  as a rule, samples represent not single-phase
  objects containing in both polycrystalline phases
  and an amorphous component.
• Such work demands not only uses of traditional,
  standard techniques of research, but also
  development of new approaches to the analysis of
  structure of substance in the condensed
  condition.
