Understanding the regulation of allometry in electrospinning would have broad implications on furthering our knowledge of the process and on controlling the diameter of the electrospun fibres. 13) where R is the dimensionless jet radius, Z is the dimensionless axial coordinate, and NW, NE and NR are the Weber number, Euler number and effective Reynolds number, respectively. 14) Shin and co-workers [23] reported an experimental investigation of the electrically forced jet, and the data revealed that the radius decreased as z increased.

This nano-effect is very similar to Arnold diffusion: the higher the dimensionality, the stronger Arnold diffusion is [1]. A review on mathematical models for electrospinning is available in [27]. 8 A section of a nanofibre, showing aggregated macromolecules in the centre and a high proportion of atoms on the fibre surface. 9 The fractal kissing problem [1]. 10 Hierarchical structure in E-infinity turbulence model [25]. 11 Hierarchical structure of the blood-vessel system where E-infinity theory can be powerfully applied [26].

3 Resistance of an electronic jet: R ~ 1/rα, α = 2δ / (δ+1). The exponent ‘α ’ can be explained as the fractal dimension of the ‘charged’ section. 34b) where α and β can be explained as the fractal dimensions of the ‘charged’ perimeter and ‘charged’ section, respectively; h and k are constants. For a conductive textile we have: If we want to design an electrochemical cell constructed of two electrodes, which are made of knitted, woven or non-woven 27 Electrospun Nanofibres and Their Applications conductive textile material, the allometry leads to the following formulation: where k is a constant, L is the distance between the electrodes, A is the surface area of the electrodes, and c is the concentration of the electrolyte solution.
