    Functional nano-structure of aggregates self-organized on the liquid/solid interface-enzymatic polymerization of ADP (1997)
    Springer
    Colloid & polymer science 106 (1997), S. 245-248 
    Details
    ISSN: 1435-1536
    Keywords: Poly(adenylic acid) (poly(A)) ; sodium bis(2-ethylhexyl) sulfosuccinate reversed micelle ; liquid/solid interface ; polynucleotide phosphorylase (PNPase) ; atomic force microscopy (AFM)
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The enzymatic polymerization of ADP was carried out in sodium bis(2-ethylhexyl)sulfosuccinate (AOT)-reversed micellar solutions. The poly (adenylic acid), poly(A), being formed in the water pools precipitated out of the AOT solution together with the enzyme, whose activity was maintained for a long time. The process of the precipitation was studied in comparison with the polymerization in cationic surfactant reversed micelles and the precipitate aggregates were observed by atomic force microscopy (AFM).

    The crystallographic structure of the natural air-hydrate in Greenland dye-3 deep ice core (1990)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 8 (1990), S. 17-24 
    Details
    ISSN: 1573-1111
    Keywords: Air-hydrate ; clathrate ; ice core ; guest molecule
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract We have carried out X-ray diffraction studies on single crystals of natural air-hydrate in deep ice cores recovered at Dye-3 Greenland. Integrated intensities for 470 diffracting planes were measured by an automated four-circle diffractometer. The space group determined is cubicFd3m and the lattice constant is 17.21(3) Å. These results indicate that the crystallographic structure is the Stackelberg's structure II, in contrast to the previously anticipated structure. This finding agrees with the recent results on the synthetic air-hydrate by Davidsonet al. It was also found by difference Fourier synthesis for guest molecules that electron density in a 16-hedral cage has multiple maxima displaced from the center of the cage while that in the 12-hedron was approximately spherical.
