Hierarchic Structure the computer and computer graphics. . I want to direct your attention to the “Generalised Crystallography” first promulgated by J. D. Bernal about 25 years ago. X-ray crystal structure analysis has been so successful that people have forgotten that most materials are not in fact crystalline.

Geometry of Films of Amphiphile Molecules: A Curved Space Approach of water without self-intersection separates two identical labyrinths of amphiphilic molecules . We wonder if the complex geometry of such structures could not rely upon the same principle than that which is easily discernable in the much simpler lamellar and smectic phases.

On the Dark Field Imaging Behaviour of Icosahedral Phases in Rapidly Cooled Aluminium Alloysicrystals in other alloy systems can exhibit other behaviour, such as diffuse scattering in reciprocal space (Mukhopadhyay .., 1987a, 1987b; Ebelard and Spaepen, 1989; Gibbons .., 1989) and/or clear thickness fringes in dark field at the edge of thin foils (Ishimasa .., 1988), but here we restrict o

Electron Microscopy and Quasicrystalscronic size, when obtained for example by rapid solidification, but also coexisting, at a more or less fine scale, with other intermetallic crystalline compounds; this last point hampers evidently characterization techniques with limited spatial resolution which sample the alloys at a heterogeneous scale or which requires a large amount of matter.

These comprise the need to recur to "exotic" spaces for describing the type of order of the atomic or molecular configurations of these system

Einführung in die Krankenhaus-Kostenrechnung really quantitative structure refinement, with a quality comparable to that of a conventional structure determination, has been performed. Table 1 gives a short list of more or less quantitative analyses of quasi crystal structures (QCS) known to the author. For a review of the state of art of QCS analysis confer Steurer (1989b).

Further experiments revealed however, that one could get the icosahedral phase under as equilibrium conditions. , and that it could coexist. with, and recrystallize into. , other crystalline structures.
