"The nine unit landsurface model and pedogeomorphic research". Sauvage erhielt unter anderem dafür 2016 den Nobelpreis für Chemie. The example of this approach consists first in a structural component, the recurring pattern of certain soils in a landscape transects in which every chain element has its place in the chain, a soil has it in a landscape. Y. Liu, S. A. Vignon, X. Zhang, P. A. Bonvallet, S. I. Khan. The interlocked rings cannot be separated without breaking the covalent bonds of the macrocycles. Das Olympiadan hat keinen expliziten Zweck, sondern ist lediglich ein Beitrag zur Grundlagenforschung, die Synthese sollte die Machbarkeit solcher Synthesen untersuchen.[6]. On a steeper slope in the middle of a catena, erosion, such as by runoff, is faster, so facets are typically thinner and drier. The importance of a catena is the variation of soils across a small area such as a slope.
