Phyllotaxis: a framework for foam topological evolution
Nicolas Rivier, Jean-François Sadoc, Jean Charvolin
Phyllotaxis describes the arrangement of florets, scales or leaves in composite flowers or plants (daisy, aster, sunflower, pinecone, pineapple). As a structure, it is a geometrica…
Conjecture on the lateral growth of type I collagen fibrils
Jean Charvolin, Jean-François Sadoc
Type I collagen fibrils have circular cross sections with radii mostly distributed in between 50 and 100 nm and are characterized by an axial banding pattern with a period of 67 nm…
Phyllotaxis on surfaces of constant Gaussian curvature
Jean-François Sadoc, Jean Charvolin, Nicolas Rivier
A close packed organization with circular symmetry of a large number of small discs on a plane is obtained when the centres of the discs are distributed according to the algorithm…
Ordering in dense fiber bundles, the phyllotactic solution and its application to collagen fibrils
Jean Charvolin, Jean-François Sadoc
The shape of the cross section of a dense fiber bundle is related to the symmetry of its molecular packing. However, this statement might be belied by type I collagen fibrils which…
Phyllotaxis: a non conventional crystalline solution to packing efficiency in situations with radial symmetry
Jean-François Sadoc, Nicolas Rivier, Jean Charvolin
Phyllotaxis, the search for the most homogeneous and dense organizations of small disks inside a large circular domain, was first developed to analyze arrangements of leaves or flo…
A Phyllotactic Approach to the Structure of Collagen Fibrils
Jean Charvolin, Jean-François Sadoc
Collagen fibrils, cable-like assemblies of long biological molecules, are dominant components of connective tissues. Their determinant morphological and functional roles motivated…
