Neutron Scattering from Cyclic Polymers,which allows manipulation of the contrast between various parts of the scattering system. This is of most use for studying individual molecules in concentrated solution and bulk samples, but it can be important even for studying dilute solutions in situations where the natural contrast for light or

Organic Cyclic Oligomers and Polymers,of chemists for a long time. The most ‘beautiful’ molecules incorporating cyclic structures might be the ‘platonic hydrocarbons’ such as the cubane ., the tetrahedrane . and the dodecahedrane . system..

Cyclization, Gelation and Network Formation,m polymerizations (as defined in Ref. 1) under conditions of chemical equilibrium. Such polymerizations have been used to good advantage, particularly by Semlyen and collaborators (see earlier chapters), for the preparation of cyclic polymers and the study of the cyclization probabilities for linear

Mit fortschreitender Denkentwicklung erkennen viele Heranwachsende, dass Regeln nicht unumstüßlich sind, sondern auf sozialer Übereinkunft beruhen. Gleichzeitig wird ihr moralisches Urteil flexibler, indem die Umstände und Beweggründe eines Handelns berücksichtigt werden.
