Natural morphology

Note-. Physical attributes are a strong function of the natural morphology and can be manipulated to some extent, as indicated below under corrective actions... 

The principal operating parameters influencing the transfer in a membrane separation processes are the hydrodynamic [9], pressure [10,11], solutes nature [12], pH [12], and of course, the nature, morphology, and thickness of the membrane. Usually, during the concentration increase of the compound interacting most strongly with polymer the membrane swells, thus the diffusion coefficient increases [13]. Therefore the compounds flow increases while the selectivity decreases [12]. 

The acid-catalyzed polycondensation of tetraethoxysilane, a silicic acid precursor, results in the formation of an aggregated silica gel (Figure 1). Con aratively, the three-dimensional structure of die aggregated silica gel was similar to the natural morphologies of the silica particles catalyzed by proteins (9) and polypeptides (12J3J7). Furthermore, e use of external force was demonstrated (21) to control the morphology (e.g. arched, fibrillar) of a silica material catalyzed by a biomimetic silaffin peptide (i.e. a non-modified Sil Ip R5... 

This chapter reviews the nature, morphology, and extent of this association and use of these structures for bone grafts, drug delivery, and extracts such as proteins for regenerative medicine. The role model for this specific biomimicry is the filtering microskeleton of Foraminifera. New selected strategies based on our and others works for the engineering of new bone based on biomimicry will be also covered. 

In summary, gross man-made fibrous structures, as well as natural morphological structures, of cotton fibers are mixed and must be considered in any modifications of properties. ...
